More information:

The economical Termax Bio 25 S double boiler is designed for heating single-family houses with an area of ​​80-250 m². The multi-energy boiler has separate fireboxes for both fuels: oil/biooil/gas/pellets and wood/solid fuels. Bio 25 S boilers include a 6 kW electric resistance system. Domestic hot water is prepared using a copper combi boiler.

The Termax double boiler is easy to use and maintain, as filling, cleaning and maintenance operations are carried out from the front. The boilers are manufactured in right- and left-handed versions. The wood side determines the handedness, i.e. in the Termax Bio 25 S Left boiler, the wood chamber is on the left side. The Termax double boiler has a 54 cm deep firebox for heating with solid fuels. The strong cast iron doors do not warp in hot temperatures like sheet metal doors. When using solid fuels, it is recommended to connect a separate 300-1500 l accumulator.

The Termax Bio double boiler series is designed for heating single-family houses of 80-250 m². They can be connected to underfloor and/or radiator heating systems. The Termax Bio double boilers form a heat generation unit in one shell, where you can always use the most economical fuel. The boilers can be used with many different fuels: Standard oil, bio-oil, gas (burner not included) or wood. Electricity and pellets are optional and can be added later.
