Our Thermobalance™ heat exchanger has better insulation and wider waterways than standard heating systems, helping to maintain higher efficiency levels and reduce maintenance even on older systems.
The boilers conform to ErP regulations and have minimal NOx emissions of <56mg/kWh (class 6). They’re designed for use with solar systems. And they can reach one of the highest seasonal efficiency levels in terms of heating.

Noise is kept to an absolute minimum thanks to the clever design of the Bluehelix Tech RRT range. In fact, you’ll barely know it’s on even when it’s fully operational, unless you take a quick glance at the boiler display.
STOP AND GO
FUNCTION
> STOP AND GO
When the boiler is fired up for short bursts of time, it can eventually affect the lifespan of the product. With the Bluehelix Tech RRT, the ignition of the burner is delayed electronically – and only activated if domestic hot water is actually used.
> SUN EASY
The range has been designed to integrate into systems built using the latest technology. Sun Easy uses electronics that simplify the use of the boiler with solar panels, either with natural or artificially created ventilation. Using a sensor on the domestic circuit, the temperature of water pre-heated by the solar panels remains constant and the burner comes on only if the temperature drops.
The casing itself has three removable panels that hide the isolation valves – they’re easy to remove and give it a sleeker, better design.
DOMESTIC
> DOMESTIC ECO-COMFORT
In ECO mode, water is heated using traditional methods, allowing a certain level of energy efficiency. In COMFORT mode, the temperature maintenance system on the heat exchanger means that the hot water supply becomes faster and more efficient. It will reach the highest level of comfort (3 stars EN 13203) and the efficiency and loading profiles comply with the ErP regulation at the top of their range. mod. 24 C - 28 C I A- XL 1 mod. 34 C IA- XXL

EASY MAINTENANCE
With the Ferroli Bluehelix Tech RRT range, we’ve designed a boiler that combines the best quality system with a high level of energy efficiency and a longer lifespan.
> EASY MAINTENANCE
> SAFE
The patented gas-adaptive technology of MC2 (Multi Combustion Control) helps to ensure optimum combustion if the air density, gas quality or pressure changes.
> NATURAL GAS LPG READY (MLR)
With a simple configuration, the boiler can operate with either natural gas and LPG. No additional conversion kits are needed.
> COST-EFFECTIVE
The range has been designed for easy installation and maintenance. And because the appliances contain fewer components (for example, it has a self-cooling burner door with no insulation panel), the cost of replacing parts that deteriorate is reduced.
> EASY TO CONTROL
The large backlit multi-functional graphic display helps you set the controls quickly and easily.

fig. A fig. B
MULTI COMBUSTION CONTROL
Our smart ‘gas adaptive’ technology – MC2 (Multi Combustion Control) – is the same type that’s used on high spec industrial units. It monitors and automatically adapts the level of combustion as the gas or flue conditions change.
HOW DOES IT WORK? – MC2 electronically controls the
relationship between the air/gas ratio and the flame ionisation signal to cope with fluctuations or reduced pressure with the inlet gas supply.
THE COMBUSTION CHAMBER
Made with AISI 304 stainless steel, the pipe that forms the heat exchanger is extremely smooth. It’s less prone to getting clogged or restricted with deposits, so the unit works more efficiently and lasts longer.
EVOLVING AND IMPROVING
The stainless steel Thermobalance™ heat exchanger has larger waterways (fig.A) than standard exchangers (fig.B), making it far more efficient. Even if there are restrictions within the system, the boiler will keep operating at the top of its efficiency range.

CONTROLLING THE SYSTEM
Any Ferroli OpenTherm remote control can be connected to the Bluehelix Tech RRT range to manage the level of comfort in the room as required. Its simple and intuitive LCD display makes it easy to programme both heating and hot water.
The Bluehelix Tech RRT boiler is designed to accommodate a second thermostat if more than one area needs to be controlled.
The PCB fuse and electrical connections are all easily accessible.
OUTSIDE WEATHER ADJUSTMENT
Coupled with optional external weather sensor, the Bluehelix Tech RRT automatically varies the system temperature depending on the weather outside. It’s a built in feature so doesn’t need a remote control to activate it; this makes configuration easier if you need to replace the unit.

Flue Protection System (FPS) – the flue check valve (installed as standard) allows for easy connection to collective pressure flue systems, for example in redevelopment projects. The collective pressure flue solution is more cost­effective for installers and where there are smaller chimney diameters.

Essential to the boiler’s operation is the availability of fresh, clean air and the ability to dispose of combustion products. This is achieved through the installation of a flue which provides ducts to the outside of the premises.
To optimise safety and performance, Ferroli flues must always be used with Ferroli boilers. Ferroli has a comprehensive range of accessories to suit complex installations and to enable the extension of flue lengths. The diagram above shows typical flueing options.

Condensing terminal positions: if the flue is to be terminated at low level then the potential effect of the plume must be considered.
The plume should not be directed: – across a frequently used access route – towards a window – across a neighbouring property

The distance from a fanned draught appliance terminal installed parallel to a boundary may not be less than 300mm in accordance with the diagram below.
