GEOTHERMAL SYSTEM TECHNOLOGY & BENEFITS

Geothermal heating and cooling technology is ideal because it provides exceptional performance while ronmentally-friendly. Your investment in a WaterFurnace system will provide you with many years of beneﬁts including:

Energy Savings

WaterFurnace units deliver 3 to 4 units of energy for every 1 unit of energy consumed. Many homeowners experience energy savings from 30% to 60% over other ordinary heating and cooling systems.

Cost Effective

Because of the extraordinary efﬁciency of a WaterFurnace system, any added investment related to installing a geothermal unit is usually more than offset by your energy savings.

Comfort

You’ll experience consistent, precise temperature control without the hot blasts of air associated with gas furnaces or the cold blow of an air source heat pump.

Reliable

The WaterFurnace reputation for reliability has been earned by using only the highest quality components, design, and workmanship. Like your refrigerator, your geothermal unit will provide many years of worry free operation.

Quiet

Unlike ordinary air conditioners or heat pumps, there is no noisy outdoor unit. Our units are designed and constructed for “whisper quiet” operation, similar to your refrigerator.

Safe & Clean

WaterFurnace units don’t burn fossil fuels, so there’s no ﬂame, fumes, combustion or concerns about carbon monoxide poisoning.

Environmentally Friendly

Your geothermal system doesn’t release harmful greenhouse gasses into the air, unlike a fossil fuel burning furnace. The reduced energy consumption of a geothermal system further reduces the need for more coal-ﬁred or nuclear power generating plants and places less demand on our current capability to produce electricity. Geothermal units use far less refrigerant than ordinary heat pumps or air conditioners, and are factory sealed to prevent leakage.

We’re conﬁdent that your investment in a WaterFurnace system will provide you with many years of savings, comfort, and safe, clean, reliable, quiet operation.

ABOUT YOUR WATERFURNACE SYSTEM

This section includes some detailed information about how geothermal technology works, and how the different components used in the system work together to provide you with the ﬁnest comfort system available. You'll ﬁnd useful information about the refrigeration process, loop systems, safety, and warranties.

Although the mechanics behind this technology may seem complicated, it's based on the same technology that's used for your refrigerator—it's simply a device that moves heat energy from one place to another. And because of the inﬁnite heat storage ability of the earth, you have a free, unlimited supply of energy in your own yard. In fact, for every one unit of electricity the system consumes, four units of energy are provided free from the earth and delivered into your home. This energy ﬂow can be easily represented by the diagram below.

Interesting Facts

• According to the Environmental Protection Agency (EPA), GeoExchange technology is the most energy-efﬁcient, environmentally-clean and cost-effective space conditioning system available.

• The EPA found that the systems can reduce energy consumption and corresponding emissions by over 40% compared to air source heat pumps and by over 70% compared to electric resistance heating with standard air conditioning equipment.

• If one in twelve California homes installed a GeoExchange system, the energy savings would equal nine new power plants.

• Installing a GeoExchange system in a typical home is equal, in greenhouse gas reduction, to planting an acre of trees, or taking two cars off the road.

• Current GeoExchange installations equal 14 million barrels of crude oil saved per year.

• The ground absorbs 47% of the sun’s energy that reaches the earth. This amount of energy

represents 500 times more than mankind needs every year.

ABOUT YOUR WATERFURNACE SYSTEM

HOW GEOTHERMAL SYSTEMS WORK

The Interesting Basics…

Geothermal heat pumps utilize some of the same technology found in your home's refrigerator. They are both devices that move heat energy. Your refrigerator removes heat from the food and transfers it to the air in your home. Your geothermal heat pump removes heat energy from the earth to heat your home and removes heat energy from inside your home to cool it.

A Ground Source Heat Pump System consists of a water-to-air or water-to-water heat pump, connected to a series of long plastic pipe buried below the earth’s surface, or placed in a pond. These systems can also utilize well water instead of the earth loop. As ﬂuid from the earth loop or well water is moved through the unit, the heat pump transfers thermal energy that heats or cools the home or building.

The ground serves as a giant solar collector, storing heat energy. At depths greater than 30 feet deep, the tem perature is about the same as the average annual outdoor air temperature for that climate. Air temperatures may ﬂuctuate as much as 50° F above and below the average annual temperature. However, only a few feet below the surface, the changes in earth temperatures are much less severe. Earth temperature variations decrease with increasing depth. During heating, the earth serves as a heat source. During cooling, the earth serves as a heat sink.

The earth loop is placed in the ground either horizontally or vertically, or it can be placed in a pond. Water (or water and anti-freeze) is circulated through the pipe, transporting heat to the heat pump during the heating mode and away from the heat pump during the cooling mode. The heat transfer takes place inside the heat pump in a waterto-refrigerant heat exchanger.

The Boring Details…

HEAT PUMP OPERATION

Geothermal heat pump systems consist of four circuits:

1. Air circuit—The duct system that distributes the air throughout the home or building and returns it to the unit.

2. Refrigerant circuit—A sealed and pressurized circuit of refrigerant including compressor, expansion valve, water-to-refrigerant heat exchanger, air coil, reversing valve. The refrigerant is either R-22 or R-410A.

3. Ground loop circuit—The piping system buried in the ground or in the pond (or well water), with ﬂuid that is circulated by pumps to and from the geothermal unit.

4. Hot water circuit—Domestic water can be heated in a geothermal unit with a device called a desuperheater. A piping connection is made from the geothermal unit to the water heater.

Each of these circuits is closed and sealed from the others—there is no direct mixing. However, heat energy does mix from the refrigeration circuit to the other three circuits.

The air circuit, the earth loop circuit, and the domestic hot water circuit always travel in the same direction. However, the refrigeration circuit will change direction depending on what mode (heating or cooling) the unit is in. (The exception to the change in direction of refrigerant ﬂow is the ﬂow through the compressor. This change of direction is controlled by the reversing valve.)

ABOUT YOUR WATERFURNACE SYSTEM

Heating Mode

During heating, a geothermal system absorbs the heat from the ground via the earth loop. The heating cycle starts as cold, liquid refrigerant passes through the water-to-refrigerant heat exchanger (coax, and also the evaporator during heating). The coax is made of copper (or copper and nickel) and consists of a tube within a tube—water from the loop travels through one tube (the inside tube), refrigerant passes through the other (outer) tube.

As the loop ﬂuid ﬂows through the coax, the heat energy transfers from the loop ﬂuid to the refrigerant through the copper wall separating the two. This heat transfer causes the cold liquid refrigerant to turn into a gas. (Unlike water, refrigerant changes from a liquid into a gas at a very low temperature.) The now gaseous refrigerant is sucked into the compressor where it is compressed. After compression, the refrigerant will be very hot (approximately 165 and discharged through the reversing valve and into the air coil.

The air coil is a radiator-like device that has thin aluminum “ﬁns” attached to the copper refrigerant tubing. The refrigerant passes through the air coil (the condenser during heating). As air from the return air duct system passes over the air coil, heat is released from the refrigerant and absorbed by the cooler air. The result is warm air (typically 95° to 105° F) which is delivered through the duct system by the blower.

The refrigerant, now cooled again, passes through the expansion valve (which acts as a ﬂow control), returning to the coax where it can accept more heat from the warmer loop ﬂuid.

This process is continuous during the heating mode.

ABOUT YOUR WATERFURNACE SYSTEM

Cooling Mode

During cooling, a geothermal system rejects the heat from the indoor air into the earth loop. The cooling cycle starts as cold, liquid refrigerant passes through the air coil (the evaporator during cooling).

As the refrigerant ﬂows through the air coil, the heat energy transfers from the warm return air to the refrigerant. This heat transfer causes the cold liquid refrigerant to turn into a gas. The compressor draws the refrigerant gas, compresses it, and discharges it through the reversing valve. During cooling, the reversing valve is energized, which changes the openings from one port to another, causing the refrigerant ﬂow to go in the opposite direction that it was in the heating mode. (However, the ﬂow to the compressor does not change direction.)

After compression, the hot refrigerant passes through the coax (the condenser during cooling). In the coax, the hot refrigerant releases its heat energy to the cool loop ﬂuid through the copper walls. Now cooled and liquiﬁed, the refrigerant passes through the expansion valve, back to the air coil. Warm air passing over the cool air coil causes the air to be cooled and dehumidiﬁed.

This process is continuous during the cooling mode.

Hot Water Assist

Many geothermal units installed in homes have an optional feature called a hot water generator. This component removes excess heat from the refrigerant circuit and adds it to a hot water circuit in the unit. For more information refer to page 47.

It is important to note that the Hot Water Assist function simply assists in preheating water. The temperature rise through the unit is generally 5 -10º F.

The amount of hot water generated is a function of the model and run time of the unit. On very hot days and cold days, the hot water generator could produce more hot water required for the home due to the long run times of the unit. On milder days when the unit has short duty cycles, the electric elements in the water heater will maintain the desired temperature so there will always be enough hot water for the homeowner.

Some installations use a single tank for storage of hot water. Other installations use two tanks to provide extra hot water capacity with added efﬁciency.

ABOUT YOUR WATERFURNACE SYSTEM

Closed Loop Systems

Horizontal Loops

Horizontal earth loops are used where the space allowed for the loop is not extremely limited. There are various designs of horizontal loops. There is not one type of horizontal loop that is best for every application. The selection of which type to use should be based on system size, space available, soil conditions and the type of excavating equipment used. Regardless of the type selected, operating costs will not vary substantially.

If you have this loop type, record information here:

Number of trenches or horizontal bores: _____ Length of each trench: _____ Number of pipes in trench: _____ Pipe size: _____

Vertical Loops

Vertical loops are used where space is limited or where soil conditions are not conducive to horizontal loops. Installing vertical loops requires the use of a drilling rig. Multiple holes are bored. A double pipe connected with a U-bend is inserted into each hole. The hole is the ﬁlled with grout to provide good contact around the pipe and to seal the hole. The vertical pipes are then connected to a header system horizontally a few feet below the surface.

If you have this loop type, record information here:

Number of bore holes: _____ Depth of each bore hole: _____ Pipe size: _____

Pond Loops

Pond loops are a cost effective way to install a geothermal system, because trenching is limited to only the supply and return piping from the pond to the house.

Pond loops consist of a series of coils connected together, and placed at the bottom of the pond. In order for a pond to be suitable for a geothermal application for a typical home, the pond should be at least ½ acre in surface area and at least 8 ft. deep, even during a dry spell. Ideally, the pond should be close to the home (less than 200 ft.). If the pond is farther from the home, the beneﬁt of using a pond loop is reduced due to added trenching, materials and pumping costs.

If you have this loop type, record information here:

Number of coils: _____ Pipe size: _____ Depth of pond where coils are located: _____

Water Supply for all Closed Loops

Closed loops require no regular maintenance. However, if you notice air noise within the piping or if your loop is ever damaged by excavation, contact your dealer.

Open Loop Systems

Open Loop or Well Water Systems

An alternative to closed loops are open loop systems, also known as well-water systems. If your system is an open loop, it uses water that comes into your home from your well. Water from the well is circulated through the unit whenever the unit is heating or cooling. When the unit is not running, it is not using any water.

Once the water has run through the unit, it is discharged into a location like a pond, drainage ditch, ﬁeld tile, etc. Water used in the unit is not re-used for other domestic purposes.

If you have an open loop, record information here:

Unit Maintenance with Open Loop Systems

Depending on the water quality, some maintenance is usually required with a well water system. Because of minerals and other particles in the water, without a routine of preventive maintenance, this material may eventually begin to clog the heat exchanger in the unit. When this happens, the efﬁciency and capacity of the unit is decreased, eventually to the point where failure may occur.

To minimize the potential of this happening, a heat exchanger cleaning schedule should be established with your dealer. The frequency will depend on the speciﬁc quality of your well water. Some homeowners ﬁnd that they can go a few years between cleanings; others may need to have the heat exchanger cleaned yearly. In order to achieve optimum performance, energy savings and long system life, it is necessary to have your dealer perform this service as needed. Remember-- preventive maintenance is less expensive than replacing major components.

The cleaning procedure requires special equipment and chemicals. Therefore, do not attempt to clean the heat exchanger yourself.

Water Supply

An adequate water supply to the unit is very important. Do not let anyone disrupt the water supply by rerouting the supply line or tapping into it without ﬁrst checking with your dealer. If the well pumping system requires service or is inoperable, your unit should be turned off or placed into emergency heat until an adequate water supply is restored.

ABOUT YOUR WATERFURNACE SYSTEM

Safety Warnings

WARNING: Equipment used for heating, air conditioning and water heating can cause injury if safety precautions are not observed. These systems generally use a 230 volt power supply which is double the voltage used by other household appliances. Electrical shock from these systems could cause personal injury or death. Before performing any service or maintenance operations on a system, turn off main power switches to the unit, and turn off the auxiliary heater power also if used.

Although your geothermal unit has been designed and manufactured with your safety in mind, and is certiﬁed to the safety standards of ETL, failure to observe safety precautions can result in injury. Only trained and qualiﬁed service personnel should install, repair, service or adjust heating and air conditioning equipment. Untrained personnel can perform the basic maintenance functions listed below. All other operations should be performed by trained service personnel. When working on heating and air conditioning equipment, observe precautions in the literature, tags and labels attached to the unit and any other safety precautions that may apply.

ABOUT YOUR WATERFURNACE SYSTEM

Warranty Explanation and Coverage

What about my warranty?

WaterFurnace offers the best warranty in the industry!

Our standard warranty provides coverage for all unit parts for a period of 10 years. In addition to replacement parts coverage, your servicing dealer receives a repair or replacement labor allowance on warranted components in the unit. However, WaterFurnace also offers several other warranty options, depending on the needs of the customer.

Your independent WaterFurnace dealer should have previously discussed with you the terms of these options, and together, you have selected the one that best ﬁts your needs. Not all customers select the 10-year coverage, so if you are unsure as to your warranty period, contact your WaterFurnace dealer.

What items are covered under the warranty?

Our standard warranty covers parts and most accessories. “Parts” are considered to be any factory-installed component inside the unit including, but not limited to the compressor, reversing valve, expansion valve, electrical components, air coil, heat exchanger, etc. Upon failure of a part, the company provides a replacement part to the servicing contractor at no charge. “Accessories” are generally external to the unit and include items like thermostats, pumps, humidiﬁers, etc. In most cases, accessories supplied by WaterFurnace carry the same warranty as the unit. Some warranties do not cover accessories. Contact your dealer to determine the speciﬁc terms and extent of your coverage.

Will I have to pay labor costs for warranty repairs?

Some warranty options include a Labor Allowance, which is an amount credited to your servicing company based on the type of repair made. The Labor Allowance is designed to reduce the cost of repairs. However, it may not cover the entire labor fee charged by your dealer. Not all warranty options include a labor allowance.
