Abstract: An integrated heating unit operates in a first heating mode, in which the heat of combustion gases is transferred to return air, and a second heat recovery mode, in which the heat of exhaust air is transferred to fresh air. The heating unit of the present invention utilizes the same heat exchanging unit and fans to transfer the heat from the combustion gases to the return air and to transfer heat from the exhaust air to the fresh air. The exhaust air is recovered from a select group of rooms, e.g. kitchens and bathrooms. A secondary heater can also be provided in the integrated unit in the form of a fireplace for providing an alternate or an additional source of the combustion gases.

Abstract: A tank-tankless water heater includes primary and secondary heat exchangers, and a combustor for the production of flue gases. In operation, water is first heated as the water and flue gases flow through primary heat exchanger. The water flows into the tank where it is stored and again heated as the flue gases flow through the secondary heat exchanger. A pump moves the water from the secondary heat exchanger, through the primary heat exchanger, and back to the secondary heat exchanger for storage as needed to maintain the stored water at a desired temperature. Water is drawn from the secondary heat exchanger during initial demand to provide a ready source of hot water, and the hot water supply is maintained by the primary heat exchanger during sustained hot water draws. The primary heat exchanger may include a temperature or temperature differential control system.

A circuit unit U is mounted such that an outer surface 11B of the heat radiating member 10 to which the circuit body 30 is fixed faces a body surface S of the vehicle with a clearance. Preferably, the mounting part 12 fixed to the body of the vehicle is extended, the surface 13 of the mounting part 12 which is in contact with the body is positioned to be substantially parallel to the outer surface 11B of the heat radiating member and a step is provided in both surfaces 13, 11B. In a mounted state, the body and the outer surface 11B of the heat radiating member are facing each other in a substantially parallel state and a clearance is formed between the body and the outer surface of the heat radiating member over the entire area excluding the mounting part 12.
