Universal cast iron boiler for houses as well as smaller structures with dead load or forced heating water circulation. The universality of this boiler lies in the possibility of adaptation from solid fuel to gas/liquid fuel and vice versa. The boiler has a long life time, low requirements for chimney draught and easy manipulation - regulation elements include only chimney flap and draught regulator for the control of combustion air supply. There is a special version with larger stoking opening for the prevalent use of wood for burning.
