These boilers have the same characteristics as high efficiency boilers with an additional heat exchanger.
It is the passage of this additional flue gas exchanger that empty their last calories, from the state of the burned gas condensing water .
Smoke temperature is lowered to about 40 ° .
The effective yield is greater than 100 %.
Caution required tubing.
- Double air stabilization and flame
- Precise centering of its elements
- Adjusting the combustion outer knob
- Solidarity and the heater nozzle line .
Burner total combustion heat repair
The technical originality of this new burner is the revolutionary way to achieve the oxidant mixture (air and fuel) .
The usual spray provided by a conventional nozzle is coupled to a thermodynamic mixing = fuel burning gaseous form.
This results in a combustion quality that has so far never been achieved consistently.
Combustion taking place in gaseous form , the flame emits very little light .
The boiler that only in contact with hot gas ensures exclusively the heat exchanger function .
Reducing exhaust temperature due to changes occurring in the process of heat transfer enable central heating boilers to achieve a combustion efficiency up to 97 %.
Fuel gas and dual fuel burner
Allows two sources of fuel and use the cheapest according to their costs.
Type of fuel :
- NL 20 : Lacq , 20 mb pressure
- NG 25: Groningen gas , pressure 25 mb
- P 37 propane, 37 mb pressure .
Or heating oil .
Passing the gaseous fuel to liquid fuel is performed by a simple operation of a switch on the upper housing part .
Scope of supply :
- Regulation of gas safety
- Injector concentric dual fuel gas
- Gas Valve dam
- Two flexible fuel
Optional: – gas filter
- the fuel filter.
The emission of heat by electricity is made possible by the passage of current through a resistive element . The electrical energy is transformed into heat energy .
There are three principles of heating power :
