ABSTRACT:
A gas fired boiler for a domestic hot water and/or central heating system has a burner (25) (FIG. 1), a static heat exchanger (22) through which water is circulated, and a rotary heat exchanger (12) of which the body is a disc of ceramic material such as is currently used for catalytic conversion in automobile exhaust systems. The rotary heat exchanger recovers heat from the gases passing from the static heat exchanger (22) to the outlet flue 4, and uses this recovered heat for heating the fresh air entering through the air intake (3). A conduit (90) having a controllable valve (91) enables heated fresh air to be supplied for space heating purposes if required, while improving the thermal efficiency of the boiler by promoting condensation of water vapor from the combustion gases as they pass through the rotary heat exchanger.
