CREST allows system designers tremendous flexibility to vary the flow rate through the boiler. It can service systems that operate with widely fluctuating flow rates depending on demand. CREST can be installed with primary/secondary piping or in a full-flow arrangement. Typical design techniques include full-flow systems or variable flow systems using variable frequency drives on the heating water pumps. In either case, CREST excels in these applications and allows the flow through the boiler to vary based on system demand. * 35 GPM min. flow on FB1500 model, 80 GPM on FB3500 model.
Sequences up to an 8-boiler system using simple 2-wire daisy-chain connection, eliminating cost and uncertainty of separate “third party” sequencer. On demand, one boiler functions as the leader and modulates to capacity. Increasing load then “cascades” to additional “lag” boilers in sequence as needed. Lead-lag rotation shifts “first on” boiler role every 24 hours, distributing equal lead-lag runtimes to each unit.
CREST’s ability to sequence up to eight units that each have as much as 25:1 turndown means that the combined system has the potential of operating with modulation of up to 200:1 turndown. A bank of eight
2.0M Btu CRESTs would be able to provide as little as 80,000 Btu/hr and as much as 16,000,000 Btu/hr of heating output. In addition, the CREST Cascade can be set for “Efficiency Optimization” with each boiler firing at the same low BTU/hr input rates to receive the benefits of the highest thermal efficiency.

Fire Tube Innovation up to 3.5 Million BTU
Lochinvar® has taken the fire-tube concept in an innovative new direction with the CREST® modulating-condensing boiler. With sizes that range from 1.5 to 3.5 million Btu/hr, you finally have the opportunity to utilize Lochinvar leading-edge technology in your largest applications. W ith thermal efficiencies up to 99% in low water temperature applications, CREST is positioned to provide exceptional energy-saving performance.
The advanced CREST introduces a combustion system with a unique burner design with up to 25:1 turndown. The burner fires into an array of 316L stainless steel fire-tubes that transfer the heat to the surrounding water with exceptionally high efficiency.
CREST communicates seamlessly and in real time with building management systems by utilizing an on-board Modbus protocol. The SMART TOUCH™ control has a built­in cascading feature that communicates with up to eight units, providing total command without an external control or complex and expensive control logic programming by the BMS integrator.
Yes, innovative fire-tube boiler technology integrated with our SMART TOUCH™ operating control makes the CREST a genuine game-changer among commercial boilers.
Advanced Negative Regulation Technology
CREST safely and reliably operates with supply gas pressure as low as 4 inches water column. Because Negative Regulation (Neg/Reg) technology draws fuel gas into a pre-mix combustion system instead of relying on utility pressure through the gas valve, operation is steady in low gas pressure systems or when peak demands occur on supply lines. Plus, Neg/Reg automatic fan speed control fine-tunes the correct fuel/air ratio entering the burner, providing even, consistent combustion for a cleaner burning flame achieving high combustion efficiency.
Fully Modulating up to 25:1 Turndown
F
25:1 turndown means the burner can fire at a rate as low as 4% of its maximum input. For example, a 2 million Btu/hr CREST unit can modulate from 80,000 up to 2,000,000 Btu/hr depending on demand. High turndown greatly reduces “short cycling” when demand is low. All boiler systems are designed to provide enough heat to maintain a facility’s heat loss on the coldest days. When the system is zoned, the CREST’s high turndown works to match the actual system demand and, in return, reduces the customer’s fuel bill and provides better comfort by load matching the heat loss of the system. Greater seasonal efficiencies will be realized due to the extremely large turndown offered by CREST.
As Low As 35 GPM* to Full 350 GPM Flow Rates
CREST allows system designers tremendous flexibility to vary the flow rate through the boiler. It can service systems that operate with widely fluctuating flow rates depending on demand. CREST can be installed with primary/secondary piping or in a full-flow arrangement. Typical design techniques include full-flow systems or variable flow systems using variable frequency drives on the heating water pumps. In either case, CREST excels in these applications and allows the flow through the boiler to vary based on system demand. * 35 GPM min. flow on FB1500 model, 80 GPM on FB3500 model.
Built-in Cascading Sequencer
Sequences up to an 8-boiler system using simple 2-wire daisy-chain connection, eliminating cost and uncertainty of separate “third party” sequencer. On demand, one boiler functions as the leader and modulates to capacity. Increasing load then “cascades” to additional “lag” boilers in sequence as needed. Lead-lag rotation shifts “first on” boiler role every 24 hours, distributing equal lead-lag runtimes to each unit.
CREST’s ability to sequence up to eight units that each have as much as 25:1 turndown means that the combined system has the potential of operating with modulation of up to 200:1 turndown. A bank of eight
2.0M Btu CRESTs would be able to provide as little as 80,000 Btu/hr and as much as 16,000,000 Btu/hr of heating output. In addition, the CREST Cascade can be set for “Efficiency Optimization” with each boiler firing at the same low BTU/hr input rates to receive the benefits of the highest thermal efficiency.

Building on a Tradition of Innovation
s t
.
Lochinvar’s commitment to research and development once again brings innovation to the industry! The SYNC™ Commercial Boiler combines stainless steel heat exchanger technology with Modulating Condensing combustion to deliver thermal efficiencies as high as 98% in low-temperature applications.
With models at 1.0, 1.3 and 1.5 million BTU/hr inputs, SYNC will serve a large range of commercial applications and add the “green” touch that building owners and facility managers desire.
SYNC also reaches new levels of innovation with SMART TOUCH™… touchscreen technology that puts total operational control at your fingertips! With SMART TOUCH, it’s easier than ever to set up a perfectly synchronized “green” system, and access a complete onboard database of real-time operational data and performance history.
Other features in SYNC include space-saving footprints, direct-vent design with intake and exhaust runs up to 100 feet, and a built-in cascading sequencer for up to 8 boilers, delivering up to 12 million BTU/hr heating capacity.
Total Control, at Your Fingertips
The full-color SMART TOUCH Main Menu screen is your gateway to complete control of all SYNC functions, and total access to system performance data and history. Do it all and see it all right here, using our SMART TOUCH software.
Direct-Venting up to 100 Feet
SYNC offers tremendous flexibility for building plan placement because it permits direct-vent air intake and exhaust runs up to 100 equivalent feet using PVC, CPVC or AL29-4C stainless steel vent pipe. Intake and exhaust runs can terminate horizontally through a sidewall or vertically through the roof
Advanced Negative Regulation Technology
SYNC safely and reliably operates with supply gas pressure as low as 4 inches water column, because Negative Regulation (Neg/Reg) technology automatically adjusts fan speed to ensure the correct volume of fuel and air entering the burner.
“Fail-Safe” Direct-Spark Ignition
With each call for heat, two electrodes ignite the fuel/gas mixture. A third electrode then senses for flame. SMART TOUCH will lock out and display the fault if ignition does not occur.
Two-in-One Stainless Steel Heat Exchanger
A primary heat exchanger combined with a secondary exchanger captures flue gas heat and allows very low return water temperatures and does not require a low-temperature bypass. The stainless
steel, pH-tolerant design features a weld-sealed assembly with no O-rings or gaskets, and does not require special glycol. ASME Section IV approved and stamped.
Fully Modulating Burner
SMART TOUCH allows fully modulating combustion with 10:1 turndown. The combustion system can operate as low as 10% of
maximum input, and modulates the firing rate up to 100% as demand increases. The burner design incorporates a woven steel mesh sleeve over a stainless steel burner tube and fires in a 360° pattern along the entire length of the primary heat exchanger. These together allow SYNC’s compact size to excel compared to units with larger multiple burners.
Built-in Cascading Sequencer
Sequences up to an 8-boiler system using simple 2-wire daisy-chain connection, eliminating cost and uncertainty of separate “third party” sequencer. On demand, one boiler functions as the “leader”, and modulates to capacity. Increasing load then “cascades” to additional “lag” boilers in sequence as needed. Lead-lag rotation shifts “first on” boiler role every 24 hours, distributing equal lead-lag
runtimes to each unit.

Infinite Modulation
With thermal efficiencies up to 87%, Power-Fin boilers feature infinitely modulating burner firing rates (turndown), precisely matching the firing rate to domestic water load requirements. The result is better overall efficiency and less cycling. Power-Fin
boilers may be specified as either 5:1 turndown (502 - 2001), 2:1 turndown (1501 - 2001), or 100% ON/ OFF (502 - 1302). With 5:1 turndown the burner fires as low as 20% of maximum input when demand is lowest and increases the firing rate up to 100% as demand increases. Models with 2:1 turndown modulate from 50% to 100% of maximum input.
Venting Options
DirectAire Horizontal
Vents horizontally up to 50 equivalent feet using Category IV vent materials. Draws combustion air up to 50 ft. from a different pressure zone.
DirectAire Vertical
Vertical venting up to 50 equivalent feet using Category I or IV vent materials. Draws combustion air up to 50 ft. from a different pressure
5
zone.
Direct Vent
Horizontal or vertical venting up to 50 equivalent feet using Category IV vent materials. Draws combustion air from the same pressure zone. This option only available with 5:1 (M) firing code models.
Common Venting
Vents multiple units vertically through one vent termination with Category II vent materials and draws combustion air from the room, roof or sidewall. Vent kit and Category IV to II conversion kit required.
Gasketless Heat Exchanger
The Power-Fin heat exchanger features an array of 20 or 24 copper-finned tubes surrounding the burner for maximum heat transfer. Lochinvar also pioneered the “gasketless” heat exchanger, which eliminates the use of O-rings and gaskets. Because of the time-proven reliability of this design, the Power-Fin heat exchanger is backed by a 5 year limited warranty.
Sidewall
Horizontal venting up to 50 equivalent feet using Category IV vent materials. Draws combustion air from the room.
Vertical

Advanced Negative Regulation Technology
KNIGHT XL safely and reliably operates with supply gas pressure as low as 4 inches water column. Negative Regulation (Neg/Reg) technology automatically adjusts fan speed that ensures the correct volume and mix of fuel and air throughout the firing range.
Two-in-One Stainless Steel Heat Exchanger
A primary heat exchanger combined with a secondary heat exchanger captures flue gas heat and condenses to utilize available latent energy. The stainless steel, pH-tolerant design features a weld-sealed assembly with no O-rings or gaskets and does not require special glycol. ASME Section IV approved and stamped.
Fully Modulating Burner
The SMART SYSTEM allows fully modulating combustion with 5:1 turndown. The burner can fire as low as 20% of maximum input and modulates the firing rate up to 100% as demand increases. The burner is a single stainless steel assembly covered with woven steel mesh and fires in a 360° pattern along the entire length of the primary heat exchanger. This allows the compact KNIGHT XL to exceed the capacity of units with larger multiple burners.
Direct Venting up to 100 Feet
KNIGHT XL offers 7 venting options and tremendous flexibility for placement of units within the building, because it permits direct-vent air intake and exhaust runs up to 100 equivalent feet using either PVC, CPVC or AL29-4C stainless steel vent pipe. A sidewall vent termination kit is shipped standard with every KNIGHT boiler.

The Foundation of Lochinvar Becomes Stronger
Copper-finned tube, non-condensing appliances are the foundation of Lochinvar’s success. In 1993, Lochinvar introduced the Copper-Fin II, the first horizontal chassis, copper-finned tube boiler to operate with fan-assisted combustion. Now, the Copper-fin II is even better. Along with high thermal efficiency, gasketless heat exchangers and multiple venting options we have added Lochinvar’s exclusive SMART SYSTEM™ control.
Nine models from 399,999 to 2,070,000 Btu/hr input provide you with exceptional products with a long list of new features in addition to the established features which redefined the industry. The Copper-fin II was the first proportional fired, fan-assisted boiler on the market. Every model features a small footprint for easy passage through a 36” door, low NOx – third party tested to less than 20 PPM, Stack Frames that can put twice the Btu/hr input in the same space and vent diameters up to 8” smaller than conventional atmospheric boilers.
SMART SYSTEM Puts More Control and Information at your Fingertips
The most exciting addition to the Copper-Fin II is the SMART SYSTEMTM control. The SMART SYSTEM is an advanced, state of the art integrated operating control. We introduced the SMART SYSTEM control in 2005 and it has delivered proven operation in thousands of demanding commercial applications. The control provides the installer, owners and operators with precise temperature control and diagnostic information.
Advanced features include:
• 2-Line, 16 Character LCD display of Setup, System Status and Diagnostic Data in Words, not codes
• Built-in Cascade sequencer controlling up to 8 Boilers
• Outdoor Reset adjusts setpoint based on reset curve
• Domestic hot water prioritization allows the boiler to provide space heating and produce domestic hot water all in one system
• 0-10 VDC BMS Input to control boiler operation
• Modbus protocol - optional
Proportional Firing
Proportional firing divides a single manifold of multiple burners into smaller, independent stages. With up to four stages of individual operation, the Smart System control can reduce the firing rate down to approximately 25% Btu/hr input. This simple but effective design matches the boiler’s firing capacity to the constantly changing system demand. Full Fire or On/Off combustion systems often fire the entire gas train in short, inefficient bursts. Stage firing delivers the Btu’s required in smoother and longer burn cycles which will improve operation and reduce component fatigue.
Gasketless Heat Exchanger
In 1989, Lochinvar was the first water heater manufacturer to offer gasketless cast iron & copper-finned tube heat exchangers. Our unique gasketless design enhances reliability by eliminating o-rings and gaskets found on other brands. The heat exchanger features glass lined headers and copper-finned tubes with extruded integral fins spaced 7-fins per inch for exceptional heat transfer. The heat exchanger is built to ASME construction standards for 160 psi working pressure and is backed by a ten year limited warranty.
Venting Options

Energy Efficient, Cost Effective Boilers
Lochinvar first introduced Copper-Fin technology to the boiler industry some 50 years ago. Since then, we’ve continued to refine and perfect it - adding advanced fan-assisted combustion, hot surface ignition, a unique gasketless cop per finned tube heat ex chang er and highly efficient insulating materials.
Installation Flexibility and Cost-Savings
With compact sizes that use less floor space than ever before, all Copper-Fin units are narrow enough to fit through a standard 36” doorway – an ad van tage most commercial boilers can’t provide. Plus, thanks to special insulating materials, Copper-Fin units require only 3” clearance from combustible walls. What’s more, our Stack Frame allows you to install two units in the area normally required for one. This makes it easier to fit
Copper-Fin
multiple Copper-Fin boilers into cramped me chan i cal rooms. And you can even use a smaller diameter vent stack - up to 8” smaller than typically required for comparable atmospheric boilers - so it saves money as well as valuable mechanical room space.
Unique Copper-Fin Heat Ex chang er
The Lochinvar Copper-Fin boiler design uses a two pass heat ex chang er. Water is circulated through a row of
high ly-efficient, finned copper tubes. The high rate of water flow creates a scour ing action that prevents sed i-
ment and lime-scale buildup, common in conventional boilers, and the finned copper tubes allow maximum
heat transfer efficiency.To create this special heat transfer capability, Lochinvar extrudes the fins from
thick wall copper tubing to precise specifications - ex act ly 7 fins per inch. The result is an integrally-
finned tube with a heat transfer ratio 9 times greater than a plain copper tube.
Heavy-Duty Gasketless Design
What’s more, advanced casting processes allowed Lochinvar to develop a unique one-piece
header system. This gasketless design provides enhanced reliability, improved durability and
optimum performance - without the problems or failures common with O-rings and gaskets.
Meets the Toughest Air Quality Standards
Because of our unique fan-assisted combustion process, the Copper-Fin exceeds today’s toughest NOx emissions requirements. An independent certification laboratory test gave us a rating of less than 20 ppm - corrected to 3% O2. And less NOx means a cleaner environment.
Enhanced to Provide Performance and Serviceability
Our enhanced Copper-Fin models offer the same reliable operation, and feature a more service friendly design. The down stream test valves and referenced gas valves are now in the upper deck for easier access, and the electrical and BMS connections have been repositioned to the front of the unit for easier installation.
The gas valves, which are referenced to the sealed combustion chamber, improve operational performance by monitoring the pressure in the sealed combustion chamber and adjusting gas flow to maintain the optimum air/fuel mixture. And the built-in air inlet filter reduces maintenance and improves performance by trapping dust and airborne particulates that can foul the burners and blowers.
With dual sight glasses (one on each end), you can easily monitor burner performance and flame characteristics throughout the entire combustion chamber.
The operator interface panel provides two-stage electronic temperature control and comprehensive diagnostic status without opening the control panel. Its user friendly design simplifies service while providing additional diagnostic information through a series of LEDs.

Lightweight, Flexible and Energy Efficient
Copper-Fin gas-fired atmospheric boilers are high-efficiency boilers that save space, save money, are lightweight, and are simple to service and install. Copper-Fin boilers are equipped with a built-in draft hood, a highly efficient copper finned tube heat exchanger, our own specially designed two-stage electronic control system, and they are approved for installation on combustible floors. Models are available with inputs from 315,000 to 500,000 Btu/hr.
Two-Stage Control System
The boiler’s two-stage electronic temperature control provides flexibility and saves fuel by
Copper-Fin
closely matching heat output to system demand. On colder days the boiler fires at full output, and in warmer conditions the boiler reduces heat output to save energy and reduce boiler cycling.

%
standard equipment on all Copper-Fin boilers, provides dramatic fuel savings by reducing the firing rate 50%. And the two-stage firing control is ideal for applications utilizing indoor/outdoor reset.* *I/O reset is available as an option.
During the majority of the heating season, less than full boiler output is required to satisfy the heat load. For this reason, Lochinvar has developed a two-stage firing system. Two-stage firing -
Copper Finned Tube Heat Transfer
The heart of the Copper-Fin boiler is its copper finned-tube heat exchanger. With this unique gasketless design, we’ve combined the best of both worlds: cast iron headers for long-lasting durability, and a copper finned-tube heat exchanger for high efficiencies and fast heat transfer. The gasketless heat exchanger design reduces the risk of leaks or system failures that are common with conventional boilers. Plus, the unit’s low-mass design means that water gets heated quickly. Not only is heat up time nearly instantaneous with these boilers, the energy consumption and operating costs are lower too.
Intermittent Ignition Device
The Intermittent Ignition Device is a solid-state electronic spark-to-pilot ignition system that reduces fuel consumption. It’s electronic circuitry continuously monitors the system and provides pilot gas only when there is a call for heat, eliminating the need for a continuously burning pilot, and providing an additional measure of operational safety.

Built-In Draft Hood
The lower overall height of the draft hood makes it easier to install the Copper-Fin boiler in all applications, especially in those instances where overhead space is limited and headroom restrictions exist.
Serviceability
This boiler is as flexible and convenient to install and service as it is efficient and compact. The heavy-duty stainless steel burners can easily be adapted for use with either natural or liquefied petroleum (LP) gas, and the boiler’s design allows for easy access to all major components for servicing. The heat exchanger is designed to slide out the front of the boiler for faster maintenance, and Lochinvar backs it up with an exclusive 10-year Limited Warranty.

Stainless Steel Fire Tube Heat Exchanger
The KNIGHT® Wall Mount, engineered with Lochinvar’s exclusive SMART SYSTEM™ control and an array of other innovative features is far ahead of any heating boiler in its class. It promises and delivers ultimate ease of installation and maintenance. With up to 99% thermal efficiency, low-NOx emissions and a fully modulating burner, it is the best ”green choice” for today’s environmentally focused market.
Seven modulating/condensing stainless steel KNIGHT Wall Mount boilers are available with 55,000–399,999 Btu/hr inputs in a space-saving wall-mounted design. All are equipped for direct-vent installation with air intake and exhaust runs up to 100 feet using PVC, CPVC or AL29-4C vent materials. This range of choices is ideal for residential or light-duty applications such as small hotels, schools and office buildings. For higher-demand applications, up to eight KNIGHT Wall Mount units can be installed utilizing the built-in cascading sequencer to deliver up to 3.2 million Btu/hr heating capacity.
The new KNIGHT Wall Mount Boiler reflects Lochinvar’s constant commitment to providing all the options you need to serve every application.
Advanced Negative Regulation Technology
KNIGHT safely and reliably operates with supply gas pressure as low as 4 inches water column.Negative Regulation (Neg/Reg) technology automatically adjusts fan speed to ensure the correct volume and mix of fuel and air throughout the firing range.
Fire Tube Design
This fully welded ASME Certified stainless steel heat exchanger uses oval shaped tubes to pass
heat from the products of combustion into the water stored in the vessel. To facilitate heat transfer the tubes are manufactured with dimples to slow the flue products and extract available latent energy. With a fire tube design the flue products are inside tapered passage ways and the water
passed through a vessel. Since the flue products pass through tubes and the water is circulated
through a larger diameter vessel a fire tube design allows for minimal head pressure loss through the boiler which allows the boiler to be installed easily into various hydronic applications.
Water-Backed Combustion Chamber
An outstanding feature of the fire tube design is a water backed combustion chamber. By having
the combustion chamber surrounded by water the Knight Wall Mount has more heating surface
area. This larger heating surface area allows for efficiencies up to 99%.
Fully Modulating Burner
The SMART SYSTEM allows fully modulating combustion with 5:1 turndown. The burner
can fire as low as 20% of maximum input and modulates the firing rate up to 100% as demand increases. The burner is a single stainless steel assembly covered with woven steel mesh and fires
in a 360° pattern along the entire length of the burner. This allows the compact KNIGHT to exceed
the modulation capacities of units with larger multiple burners.

length of the primary
heat exchanger.
Direct Venting up to 100 Feet
KNIGHT offers 5 venting options and tremendous
flexibility for placement of units within the building,
because it permits direct-vent air intake and exhaust runs
up to 100 equivalent feet using either PVC, CPVC or AL29-4C
stainless steel vent pipe. A sidewall vent termination kit is standard
equipment with every KNIGHT boiler.

It’s the Little Things
The Efficiency+ is quietly heating more and more homes and small businesses across America and throughout the world. This quiet revolution is the product of years of research and development, which has resulted in a boiler that provides all the bells and whistles typically found on commercial boilers in a package small enough to fit in a closet. Operating at 84% thermal efficiency, the Efficiency+ easily meets expectations and requirements. What makes the Efficiency+ unique is its ability to focus on the little things - so you don’t have to.
Ease of Installation
When installing the Efficiency+, you’ll notice that the details have all been taken care of. It’s smaller than most units of comparable Btu/hr input, so it will fit just about anywhere you need to put it. And it is available with four venting options, including horizontal and vertical direct venting, so wherever you put it, it’s easy to vent - with or without a masonry chimney. Plus, it weighs less than comparable units because of design advantages such as a copper finned tube heat exchanger and Loch-Heat insulation material - so it can be handled by just one man.
Serviceability
TM
tile - a remarkably light
The Efficiency+ is designed to be installed and forgotten about, quietly and reliably heating away. It includes an integrated control system that ensures safe burner operation and prevents flame-failures. It continuously monitors the flame and can even restart the ignition sequence automatically. Plus, the Efficiency+ comes standard with a burner flame observation port and internal diagnostic lights which can help pinpoint any problems, making trouble-shooting easy.
Two Stage Firing
The Efficiency+ more than lives up to its name with an outstanding 84% thermal efficiency rating. Two-stage firing is standard on all Efficiency+ boilers, providing dramatic fuel savings by reducing Btu output by 50%. This means when outdoor temperatures become warmer, the boiler will use less fuel to maintain comfortable indoor temperatures, matching the heat output to the system demand and maximizing operating efficiency.
The Details
The Efficiency+ is full of hidden advantages - details you’ll notice when they matter most. For example, if you live in the Northeast or in the Mountain States, where natural gas supply pressure can be as low as 4 inches of water column, you’ll appreciate the fact that the Efficiency+ is designed to operate on low gas pressure. If you’re using radiant heating, you’ll love that the Efficiency+ is easy to adapt to the low water temperatures typically used in radiant heating, and that the unit’s low-mass design means that water gets heated quickly, delivering a quicker response to demand and providing significant savings. And everyone can appreciate the fact that the Efficiency+ has the lowest NOx rating in the industry, helping to keep our environment safe.

Flexibility is the Solution
What could be better than a high-efficiency boiler that saves space, saves money and helps resolve all your heating problems? How about one that’s lightweight and simple to install, too! That’s the Solution™ boiler by Lochinvar finned tube heat exchanger, to our own specially designed two-stage electronic control system, the Solution boiler offers these features and many more in models up to 260,000 Btu/hr. Plus, all Solution boilers are equipped with top water connections, a built-in draft hood, and are approved for installation on combustible floors.
Copper Finned Tube Heat Transfer
The heart of the Solution boiler is its copper finned-tube heat exchanger. With this unique gasketless design, we’ve combined the best of both worlds: cast iron headers for long-lasting durability, and a copper finned-tube heat exchanger for high efficiencies and fast heat transfer. The gasketless design reduces the risk of leaks or system failures that are common with conventional boilers. Plus, the unit’s low-mass design means that water gets heated quickly. Not only is heat up time nearly instantaneous with the Solution boiler, the energy consumption and operating costs are lower too, with a rating of 84% AFUE.
Two-Stage Control
The Solution boiler’s two-stage electronic temperature control provides flexibility and saves fuel by closely matching heat output to system demand. On colder days the boiler fires at full output, and in warmer conditions the Solution boiler reduces heat output to save energy and reduce boiler cycling.
®
. From the highly efficient copper
During the majority of the heating season, less than full boiler output is required to satisfy the heat load. For this reason Lochinvar has developed a two-stage firing system. Two-stage firing - standard equipment on all Solution boilers, provides dramatic fuel savings by reducing the firing rate 50%. Two-stage firing is ideal for applications utilizing indoor/outdoor reset* and is advantageous in systems where the Solution boiler is used with an Squire indirect water heater to produce domestic hot water. *Outdoor air reset is available as an option.
PVC/CPVC Vent Kit (optional)
Vent up to 25 feet out a sidewall or rooftop with inexpensive PVC/ CPVC (CB 45-135).
Simple To Service
The Solution boiler is as flexible and convenient as it is efficient and compact. For example, the heavy-duty stainless steel burners can easily be adapted for use with either natural or liquefied petroleum (LP) gas. What’s more, Solution boilers allow easy access to all major components for servicing. We even designed the heat exchanger to slide out the front of the boiler for faster maintenance, and we back it all up with our exclusive 20-year Limited Warranty.
Built-In Piping Solutions
Other boilers often require system piping upgrades which are cumbersome and expensive. The Solution boiler eliminates this problem with its built-in, performance loop. The loop maintains constant flow through the boiler when only a single zone of the system is calling for heat. This helps maintain peak system performance by keeping the copper heat transfer surface clean and operating at top efficiency. And the top water connections make replacements a snap by fitting into existing piping arrangements without additional elbows and connections.

Total System Efficiency
Lochinvar Buffer Tanks are a cost effective way to enhance small load effectiveness and increase heating system efficiency. Lochinvar Buffer Tanks are also engineered as the system air separator, further reducing the installed cost of your system, since there is no need for a separate system air separator. System run time is important to overall operating efficiency. To prevent short cycling of the system, it is important to minimize boiler on/off cycling.
Air Elimination System
The tank’s tangential connections create a swirling action in the center of the unit as water enters and exits, pushing any air held in the system to the center of the tank. The collection tube at the tank’s center captures that air and releases it through the air eliminator installed on top of the tank.
ASME Construction
All models constructed in accordance with ASME Section VIII, Div. 1 standards and labeled for 125 psi working pressure at 400°F.
Energy Saving Performance
Jacketed tanks meet the requirements of the latest ASHRAE Energy Efficiency Standards. The 2” foam insulation provides low standby loss for optimum performance.
Five Year Limited Warranty
Provides protection against tank failure resulting from defects in materials or workmanship.
BUFFER TANK/AIR ELIMINATOR
Buffer Tank Sizing and Selection
The recommended gallon capacity of a Lochinvar Buffer tank is determined from five parameters. These parameters are utilized in the following formula and are explained below:
Desired Run Time x (Minimum Boiler Output – Minimum System Load)
System T x 8.33 x 60
Parameters:
• Run Time (Minutes) - The amount of sustained firing time of each boiler cycle once a call for heat is detected. Lochinvar recommends a minimum run time of 10 minutes.
• Minimum Boiler Output (Btu/hr) – The output of the boiler; based on the boiler’s minimum firing rate and efficiency.
• Minimum System Demand (Btu/hr) – The heating demand of the system when the smallest appliance or zone has a call for heat. This value will vary depending on the building design and application.
• System T (°F) – The change in temperature across the system. This value will vary depending on the building design and application.
• 500 (Btu•min/(°F• Gal•hr) – Constant to convert minutes per hour and the specific gravity and weight of water.
Sizing Example:
Size a buffer tank for a PBN2001-M9 (5:1 Turndown and 87% efficiency at minimum firing rate)
• Minimum Boiler Output = 348,000 Btu/hr
• Minimum System Demand = 50,000 Btu/hr (for example only, actual System Demand will vary)
• System T = 40°F (for example only, actual System T will vary)
• Run Time = 10 minutes
10 min x (348,000 Btu/hr – 20,000 Btu/hr) =3,460,000 = 173 Gallons 40°F x 500 20,000
Based on this calculation; the recommendation would be for a RVU200 Buffer Tank
(Lochinvar recommends a minimum run time of 10 minutes)

Reduce Short Cycling
Lochinvar’s Stainless Steel Buffer Tanks are designed to provide thermal storage volume and hydraulic separation of the boiler or heat pump and the building distribution system. A properly applied buffer tank will reduce on/off cycling (short cycling), which will lead to longer runtimes, higher efficiencies and longer equipment life. Squire buffer tanks can be used in geothermal, chilled water applications, and any system with low-mass boilers.
Thermal Storage
Hydronic buffer tanks are utilized to provide thermal storage volume when the system demand is less than the lowest firing rate of the boiler. This occurs most often when there are “micro” zones in the distribution system whose demand is below the minimum firing rate of the boiler. Under these conditions the boiler fires at its minimum rate, which is more energy than can be absorbed by the distribution system, and shuts off because of high return temperatures before the “micro” zone’s call for heat is satisfied. The boiler system continues to receive a call for heat and fires again. The “micro” zone cannot absorb all the energy produced by the boiler, and again the boiler shuts off because of high return temperatures. With the volume provided by the tank the additional energy not utilized by the “micro” zone can be stored in the buffer tank and used when there are additional heating demands.
Hydraulic Separation
Lochinvar’s Squire Buffer tanks also function as hydraulic separators, effectively separating the flow in the boiler loop from the flow in the distribution system. This is beneficial when the flow rate in the distribution system is different than the flow rate of the boiler system. It can be very important when there is a variable speed pump in the distribution system whose flow rate can be less than that of the boiler pump.

Another Space-Saving Idea
Lochinvar’s technology not only makes our water heaters and boilers more efficient, it means they also have a smaller footprint. So they save space, as well as operating costs.
System
And now there’s a way to get greater flexibility and reliability, save even more space, and get a system that’s perfectly matched to a facility–thanks to the Stack Frame from Lochinvar.
Match Load And Capacity
With this versatile stand, you can stack almost any combination of our ARMORTM, KNIGHT®, Copper­Fin®, Copper-Fin II®, Efficiency+®, and SolutionTM water heaters and boilers so you can achieve the perfect Btu/hr capacity for each application.
For example, a facility needs a Copper-Fin II boiler with a total capacity of 1.6 million Btu/hr. Instead of installing an oversized CHN1802 unit or a smaller CHN1442 model, now you can combine two units – CHN0992 and CHN0652 models– to exactly match the facility’s needs.
Plus, the total footprint of this combined system is just over 10 inches wider that the CHN0652 unit alone, making it smaller than either the CHN1802 or CHN1442
model. All thanks to the Lochinvar
Stack Frame.
No Assembly Required
Lochinvar’s Stack Frame is fully factory assembled and shipped in one piece. The frame is welded using square steel tubing by certified welders. Each frame is designed and tested for each specific application.
Added System Benefits
This modular design provides two other important benefits. First, it allows for system turndown for greater efficiency when demand is lower. And second, it ensures against system failure by utilizing two independent but complimentary units.
For residential and light commercial needs or commercial applications of up to 4 million Btu/hr the Stack Frame gives greater flexibility without a significant increase in stack size or overall system dimensions.
Once you’ve determined a facility’s requirements and the exact models needed, utilize the charts provided to calculate total system dimensions.

NOTE: Stack Frames are for indoor applications only.
Our compact Efficiency+® requires even less space when stacked on a Stack Frame.

Ideal for use with Copper-Fin, Copper-Fin II and Power-Fin Boilers
When designing a boiler system with return water temperatures below 130°F it is necessary to protect the boiler from flue gas condensation. All non-condensing boilers will develop operational problems if they are continually exposed to system return water temperatures below 130F. Typical systems that require this protection are water source heat pump systems, in-floor radiant heat systems, greenhouse heating, soil heating, process operations and manufacturing operations. Aditionally, heating systems that utilize nighttime setback, night/weekend shutdown or outdoor reset control strategies should incorporate low water temperature protection.
To prevent low return water temperatures to the boiler and combat operational problems, the system should be piped in a primary secondary piping arrangement with a low temperature bypass. Manual bypass systems however are not the ideal solution due to varying flow rates and firing rate of the boiler. A better alternative is Lochinvar’s Low Temperature Valve, which is a self-contained automatic thermostatic 3-way valve that ensures temperatures entering the boiler remain above 130F.
