Fuel fired heater

Abstract

Abstract A fuel-fired heater, in particular a gas heating boiler, is provided with an integrated service water heater employing the storage principle for heating up heating water. In order to achieve the result that an optimum heat utilisation takes place in the heating boiler and, at the same time, the hot flue gases of the heating boiler can be utilised with very low expenditure on equipment for heating the service water, the service water heater (6) is surrounded at a distance by an external jacket, the free space (28) between the wall of the service water heater (6) and the outer jacket has hot flue gases emerging from the heating boiler flowing through it. <IMAGE>
