Device for better utilisation and distribution of the thermal energy released in heating systems

摘要

A closed air supply system which is operated by a blower is used to supply warm air to a consumer through an air heat exchanger surface in or around a component, of a heat generator, conducting exhaust gas. The blower is controlled by an adjustable flue gas thermostat switch so that the energy contained in the flue gases can be used without any problem down to a lower limiting value which results from the structural conditions. Particularly avoided in this case are condensation problems which frequently arise in the case of direct installation of water-conducting heat exchanger surfaces in the exhaust gas flow. The use of simple components renders possible here a real optimisation of the efficiency of heat generators.
