摘要
A gas-fired condensing convector or convector/radiant room heating appliance comprising a sealed combustion chamber 12 communicating with a baffled heat exchanger 21, a gas burner 13 within the chamber 12 fed with forced or induced air for combustion from a toroidal air blower 16, a convector fan 25 for circulating air over at least the heat exchanger, and a small bore flue pipe 24 terminating in a two-way outlet terminal means for the discharge of waste gases and liquid condensate. The thermal efficiency of the appliance is at least 90% and the temperature of the waste gases is below the dew point and at less than 50°C.
