F 20-50 Log Boiler

With complete operation from the front and the largest filling opening of comparable boilers on the market, the HDG F20-50 offers maximum convenience.
Available in 20kW, 25kW, 30kW, 40kW and 50kW models. The F Series 20-25-30 has a 155 litre fuel chamber volume and the F Series 40-50, 205 litres.

Technology makes the difference

Convenience redefined

During the development of the HDG F20-50, the focus was on one thing above all: maximum convenience! For this reason, the filling opening, for example, is uncompromisingly large, making refuelling child's play. Or the flue gas flap, which not only eliminates the need for a heating door, but also ensures clean and odourless conditions in the boiler room.

These and many other clever details make the HDG F20-50 one of the most convenient log wood boilers on the market.
