Bio heaters

Affordable and renewable energy

Bioenergy can replace environmentally harmful and expensive fuels, such as oil. By using renewable biofuels, we can secure a clean, vibrant and self-sufficient world for future generations. You can burn for example wood chips, peat, pellets and grain-cleaning waste with the bio heaters.

An environmentally friendly and durable bio heater enables significant savings in energy costs. The higher the moisture level of the grain is, the larger the savings. The efficiency of the Mepu bio system’s heat exchanger is excellent.
