A heating device for supplying hot water to home heating systems and hot water faucet outlets in the home includes a combustion chamber which is adapted to burn wood fuel for supplying the necessary heat. The heating device comprises a base member containing an ash bin and ash door for the removal of burnt fuel, a water tank positioned on the base and sealed thereto, the water tank containing therein the combustion chamber which includes a grate which rests over the ash bin, the water in the water tank substantially completely surrounding the combustion chamber, the combustion chamber further including an exhaust pipe for removing exhaust combustion gases from the combustion chamber out of the heating device, the water tank being fully enclosed by an insulating shell which fits over the top thereof. A thermostat is used to sense the temperature of the water and actuate a solenoid for opening and closing an air intake duct in the ash bin controlling the amount of air passing through the ash bin and into the combustion chamber whereby the rate of combustion in the combustion chamber can be accurately controlled. An auxiliary hot water coil is placed in the water tank for heating water passing through the coils for use in the home hot water faucet outlets.
