The kW for wood-burning stoves is different from the output of a car. This is because the actual heat output depends primarily on the amount of wood selected. A rather small wood charge produces 3.0 - 5.0 kW, a very large one can also mean 10.0 kW and more.
The kW specification of a stove documented on the type plate of each stove only says with which wood support this stove was tested according to DIN. Each manufacturer can decide whether to have the stove tested at 3.0, 4.0 or 6.5 kW. As a rule, manufacturers decide in favour of the output that promises the best emission values after a few preliminary tests on the test bench.
DROOFF takes a different approach - because we want to give you the good feeling that every model works particularly cleanly with small AND large wood deposits in a verifiable and documented manner. That's why we have had all models up to 2019 tested with 4.0 kW and 8.0 kW. We test all newer models with 6.0 kW and partial load testing - this means that the complete range between 3.0 kW and 6.0 kW is covered by our DIN testing.
Our models can therefore be used for any heat requirement without exception. Regardless of whether your chimney sweep or energy advisor recommends a stove with a low or high output - our stoves are approved and ideally suited for all requirements! And when making your purchase decision, you can concentrate solely on which model you like best!
