Since the emission behaviour of single-room heating appliances for wood logs depends to a large extent on the operator and his or her behaviour (what type of wood is used, which size, how is it lit, etc.), the association is also involved in customer education. Thus, the correct use and operation of fireplaces is of particular importance and this is where the association sees its responsibility. Under www.ratgeber-ofen.de and www.richtigheizenmitholz.de, operators and those who are thinking of purchasing a single-room fireplace for solid fuels will receive help and support in important matters. The brochure of the HKI "Heating with wood - how to do it right". But also in the press the association constantly informs before and during the heating season about the correct handling of the wood fire.

In conjunction with the energy crisis and the issue of "security of supply", some new stove owners with little to no experience in using the wood fire have come along. Therefore, in 2022 and for the 2023 heating season, the association offers individual and free training for municipalities, through the Association of Towns and Municipalities. With interest and a number starting from ten participants, one needs only a suitable premise locally. Besides the federation supports the tendency of the chimney sweep handicraft for more time with the customer to get, in order to be able to accomplish here still more intensively a Erstberatung. Because the chimney sweep handicraft has to accomplish a unique consultation for heating with wood on basis of the 1. BImSchV. So far this is not sufficient however. Thus a fuel examination would have to take place annually and also an examination regarding the correct handling of the fire place and for answering questions, so that operating errors do not happen at all. After all, regular on-site consultation can reduce errors and thus prevent emissions. Fuel dealers are also trained as part of the "Clean Wood Fire Cooperation" to advise customers when necessary. Especially with regard to storage and handling of the raw material, the fuel dealer is very close to the customer.

When operated correctly and with the help of modern control and sensor technology that regulates combustion itself, the stove achieves a high degree of efficiency and wood is saved. This makes heating even more sustainable and environmentally friendly overall. Together with the latest filter technology, particulate matter and other emissions are significantly minimized.
