Technology log wood boiler HVZ-Pro 35
Heating with wood used to be tedious and cumbersome. After years of progress, Biotech has developed a firewood boiler that combines modern, comfortable heating with a robust
and cost-effective fuel.

This is how the log boiler HVZ-Pro 35/55 works
The log boiler works on the principle of the grate burner with a separate combustion chamber. The glowing charcoal is located on the grate surface, which constantly produces new wood gas through the particularly good sliding log wood. Through the flame channel, the wood gas is completely converted into pure energy at high temperatures in the fireclay combustion chamber with the precise introduction of secondary air.

Movable grate
The movable grate allows easy cleaning
by pressing the grate cleaning lever.
Lambda probe
While dIn the combustion process, the lambda probe monitors the correct dosing of the combustion air. In cooperation with the flame temperature sensor, a precise power adjustment to the current heat requirement is guaranteed.
