Abstract: A heating system has a heating unit with a combustion chamber for burning wood pellets or other pelletized fuel. The heating unit is controlled by a process control module that automatically keeps all operating functions within predetermined limits for safe, efficient and easy operation. The unit also includes a combustion air distribution assembly with a stir shaft that rotates within the combustion chamber and introduces combustion air through orifices along the length of the shaft to enhance fuel combustion. A thermo cycle plumbing assembly serves as a safety feature by preventing overheating in the event of a power failure or pump failure. Also included in the unit is a removable insulated firebox burn chamber that provides a high temperature combustion atmosphere and a heat/particulate recovery module which provides maximum heating efficiency and reduces emissions, meeting EPA requirements and contributing to a cleaner environment.

Abstract: A furnace located outside of a building or other enclosure to be heated with the furnace utilizing waste oil as a combustible fuel. The furnace is associated with a storage tank for the oil which includes a preheater or warmer therein as well as an oil preheater located in the oil supply line between the tank and furnace with the oil preheater being located adjacent the furnace and being preheated by the hot water produced by the furnace with the preheater or warmer in the tank also being communicated with the hot water heated by the furnace to reduce the viscosity thereof to facilitate the oil being pumped to the preheater and furnace. The hot water produced by the furnace can be used to heat water to be used for domestic purposes through a heat exchanger and also provide fan coil units with hot water and many other purposes.

Abstract: 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.
