DOMUSA DualTherm 25 combined boiler

Description

For the DUAL THERM boiler, the basic fuel is wood pellets, the alternative fuel is piece wood.

The production design of the boiler ensures a very efficient transfer of combustion energy to the heating system. The result is a low flue gas temperature

– electronic control system-

controls fuel combustion processes. Depending on the amount of fuel in the burner, it controls the exact amount of air so that the required boiler temperature and combustion quality can be achieved. This creates optimal conditions for combustion, especially at a reduced power level

– boiler performance modulation –

*brings optimal use of fuel energy, while the boiler performance corresponds to the actual heat consumption in the heating system. The wide spectrum of modulation and the boiler's ability to work with reduced output eliminate the cyclic states of turning on/off the boiler. Minimization of energy losses is thereby achieved, especially if the boiler is installed without an accumulation tank

*modulation of the fan speed, enables a longer heating time when operating on lump wood

A large combustion chamber, in which you can insert pieces of wood up to the length 50 cm

DUAL THERM enables the use of wood or pellets according to the user's current preferences without the need to intervene in the boiler construction. The operating mode of the boiler burning lump wood will automatically change to operation with pellets if the firewood in the combustion chamber has burned out

-Integrated pellet magazine –

The boiler is equipped with an auger for automatic feeding of pellets with a capacity of 110 kg of pellets.
