Description/Abstract A combination space heating and tankless hot water heater, is described comprising: (a) a vertical closed tank, having upper and lower ends, adapted to hold a large reservoir of liquid heat transfer medium therewithin; (b) a high-efficiency gas/liquid heat exchanger disposed within the tank; (c) burner means disposed within the generally cylindrical combustion chamber to provide hot gases to flow upwards through the gas/liquid heat exchanger for transfer of heat from the gases across the walls of the gas/liquid heat exchanger and to the heat transfer medium; (d) means for withdrawing and returning the heat transfer medium from and to the tank to supply the heat transfer medium to means for forced circulation for space heating; (e) heat exchanger means disposed within the tank for receiving cold water and supplying domestic hot water; and (f) a baffle arrangement disposed in the lower end of the combustion chamber and lying underneath the burner substantially preventing any surface upon which the tank is supported from receiving radiant heat transfer from the burner and causing some combustion air to the burner means to flow across and cool a portion of the surface upon which the combination space heating and tankless hot water heater is supported.
