Condensing technology and solar collectors are available to provide the necessary thermal energy for heating and service water, save energy, and relieve the environment.
The solar collectors are mounted on the roof that faces south. The energy provided by the solar collectors is collected in a heat storage tank in the boiler room and is available for hot service water and space heating, underfloor heating, and radiators.
A pipe of 10 cm diameter is installed in the existing chimney for exhaust gases.
