Heating with wood is extremely cheap - even if you don't have a forest yourself. It doesn't harm the climate, strengthens the local economy and is crisis-proof because wood is available in abundance in Europe. A modern log boiler is highly efficient. You usually only need to add fuel once a day, maybe twice on very cold days. But a log boiler never runs fully automatically.
ETA has the ideal solution for anyone who wants to use the extremely inexpensive fuel wood and still enjoy fully automatic comfort whenever they want. The ETA TWIN consists of two fully functional boilers that complement each other perfectly. The ETA SH log boiler can be ordered with a flange to which a fully automatic pellet boiler can be easily connected - even years later without having to modify the heating system or the chimney connection.
Advantages of the ETA log boilers:
You only need to add fuel once or twice a day. The fuel is automatically lit using the remaining embers from the last burn and without matches, paper or wood chips. As a result of the good burnout, the ETA SH only needs to be cleared of ash every one to two weeks. The ash settling area is easily accessible and is located at the front of the boiler. The heat exchanger is cleaned semi-automatically - simply pull the lever. The boiler is controlled intuitively via touchscreen.
Adding wood without matches: The log boiler works with half-meter logs that are placed in a large filling chamber. This means that it normally only needs to be added once a day - or twice at most on cold winter days. The added wood burns itself with the remaining embers from the last fire. If there are no embers left, a little paper and a match are enough. When the door is closed, the boiler's firing phase starts automatically.
Technology for maximum efficiency: Different types of wood have different burning properties. A lambda probe detects the nature of the fuel and the air supply is automatically adjusted to the quality of the wood. The ETA log boiler therefore always gets the highest possible efficiency out of mixed wood or wood briquettes. Particularly high temperatures are required to ensure that even the last combustible residue is converted into thermal energy. In the patented glow zone under the grate, even the most stubborn wood tar burns off at 900 to 1,100°C. Thanks to this thorough burnout, the ETA SH only needs to be deashed every one to two weeks.
