Abstract

The boiler (1) of a central heating system has a secondary heat exchanger (3) which extracts heat from the combustion gases as they pass from the outlet duct (2) to the chimney (4). The flow of water into the heat exchanger (3) is controlled by a valve (9) and thermostat (11) in the water return line (5). The valve (9) shuts off the flow to the heat exchanger until the water in the pipe reaches a predetermined temperature. This temperature control prevents the temperature of the combustion gases in the heat exchanger falling below the dew point and causing condensation.
