TopVent® gas
Modular gas burner

The system generates heat where it is needed and guides it directly into the large interior space. It requires neither a boiler room nor a warm water distribution network.


The automatically adjustable Air-Injector reduces the temperature stratificaiton in interiors to 0.15 K per meter height, keeping heat loss through the roof to a minimum.
