Gas boiler Auer Pulsatoire

газов котел


  • Low fumes temperatures, as low as 25°C, giving the possibility to use a simple PVC pipe to channel fumes up to 25 meters.
  • Installation is simple and quick
  • The PULSE boiler is operating without burner, which is the best solution for a long lasting efficient operating



The PULSE boiler is the only boiler replacing a continuous flame with a series of micro-combustions (without burner), which is a self-sustained system.
How it works ?
The air/gas mix is introduced directly into the combustion chamber and this creates a micro-combustion. The combustion gas are channeled through the pipes of the coil heat exchanger, creating a pressure drop. The pressure drop allows a new flow of air/gas mix into the chamber. This cycle repeats itself and is self-sustained at a rate of 115 micro-combustions every second.
Because of a revolutionary concept, the PULSE boiler provides a real efficient thermal exchange for a lower energy consumption.
How it works ?
The heat exchanger is made of 18 coiled pipes located below the combustion chamber. This heat exchanger is dipped into heating water to optimise thermal exchange. Pressure/loss of pressure alternating with the same rythm as the micro-combustions are creating a turbulent flow of burned gas into the heat exchanger, ensuring an astonishing efficiency of the thermal exchange with the heating water.
