ABSTRACT:
A heating system including a hot water heater and an air duct distribution system employs a housing having a heat exchanger located within its interior in association with a blower. Water conduits lead between the heat exchanger and the hot water outlet and the cold water inlet of the water heater. Water is passed from the hot water outlet of the water heater to the heat exchanger through a water conduit and then returned to a second conduit which passes through a pump to the cold water inlet of the water heater. The pump forcibly moves the water through the above circuit. Heat is exchanged from hot water flowing through the heat exchanger to air which is passed through the heat exchanger by a blower. After being heated the air is forced into the air duct for distribution. The system can be augmented with a second heat exchanger placed in the flue of the water heater. This second heat exchanger forms a part of the conduit between the hot water outlet of this water heater and the heat exchanger and extracts waste heat from the flue of the water heater prior to flow of the hot water to the heat exchanger.
