Class A+: where with the combination of the special thermostat and the external sensor (optional) it reaches the top efficiency class class A+ (from G to A+++)
MC 2 : Multi Combustion Control, new custom-industrial-technology-gas combustion system with patented technology for better adaptability to changes in gas pressure in the network (eg pressure increase or decrease)
M.G.R : Methane, LPG, Propane, Ready with one simple setting the boiler can work with methane, LPG and propane without the use of additional conversion kits
Exclusive self-cooled exchanger-burner system: simplifies maintenance and reduces costs thanks to fewer parts that need to be replaced
Instant domestic hot water production with a special DHW plate heat exchanger
All hydraulic components are covered by the boiler shell
Large illuminated multi-purpose display to set parameters easily and correctly
By-pass in standard equipment
ADVANTAGES OF BLUEHELIX TECH RRT C:
Particularly suitable for operation in "heavy-duty" chimney requirements thanks to the approval of flue gases with a diameter of 50 mm
FPS: Flue gas Protection System. The flue gas control valve included in the standard equipment offers easy connection of several boilers in one chimney, according to the UNI 7129 regulation
Designed to simplify and facilitate maintenance and cleaning tasks
Set up solar system: installation for hot water production in combination with solar systems
STOP AND GO: you can delay the ignition of the burner by starting it only when you actually use the domestic hot water
3-star certification in DHW production mode according to the EN 13203 standard
Minimum emissions (class 6 according to EN 15502-1)
Compensation function via external temperature sensor (optional)
Low consumption electronic pump (ErP Ready - Class A)
Digital flame control with three ignition attempts if operation is blocked due to failed flame detection (methane operation)
Installation location: also outdoors, in a partially sheltered place down to -5°C with standard equipment even at -15°C with the addition of the optional antifrost kit
