Abstract:
A water heater includes a tank containing water to be heated and a thermal displacement conduit communicating between a portion of the tank and a receptacle. Water is displaced out of the portion of the tank, through the conduit, and to the receptacle during thermal expansion of the water during heating.
Abstract:
The objective of the present invention is to provide a combustion device enabled with heat recovery of exhaust gas, so as to enhance heat efficiency by increasing the temperature of a premixed gas, by allowing heat exchanging between the exhaust gas, which is discharged through an exhaust duct, and the premixed gas, which is introduced from a burner. To this end, the present invention comprises: a combustion chamber (200), in which a burner (210) for combusting the premixed gas that is supplied from a blower (100) is installed, so as to allow combustion; a heat exchanger (300) in which heat exchanging takes place between a combustion product, which is produced by the combustion by the burner (210), and heating water, which flows along the inside of a heat exchange pipe (310); a heat exchanger case (400) in which the heat exchanger (300) is seated, and which is provided on one side with an exhaust gas passing aperture (450) that connects to an exhaust gas exhaust cover (600); and a heat exchanger front surface cover (500) which couples to the combustion chamber (200), the heat exchanger (300), and the heat exchanger case (400), wherein the exhaust gas exhaust cover is further provided for guiding the exhaust gas to come into contact with an outer wall of the combustion chamber (200) and then discharged to the outside, so that heat exchanging takes place between the exhaust gas, which is discharged through the exhaust gas passing aperture, and the premixed gas that is introduced through the burner (210).
Abstract:
The aim of the present invention is to provide a hot-water supply heat exchanger provided with a mixing valve, which has a simple configuration and enables the temperature of hot water to be easily controlled, and to an adaptor having a built-in mixing valve. To accomplish the aim, the hot-water supply heat exchanger of the present invention comprises: a heat-exchanging unit (100) for exchanging heat between the heating water supplied from a main heat exchanger (20) and cold tap water; a heating water inlet port (212) for feeding the heating water into the heat-exchanging unit (100); a heating water outlet port (214) for discharging the heating water after the heating water exchanges heat with the tap water in the heat-exchanging unit (100); a tap water inlet port (222) for feeding the tap water into the heat-exchanging unit (100); a hot water outlet port (224) for discharging the tap water, which has become hot water after the tap water has exchanged heat with the heating water in the heat-exchanging unit (100); and a mixing valve (230) for mixing the tap water fed via the tap water inlet port (222) with the hot water discharged via the hot water outlet port (224).

Abstract:
The invention concerns a gas water heater comprising a reservoir (1) equipped with an cold domestic water supply (2) intake tube and an outlet tube for hot domestic water (3), a heating element (6), penetrating inside the reservoir (1) through an opening (4) thereof, and which contains a combustion chamber (24), wherein is arranged a burner (7), and an exhaust duct for burnt gases emerging through an orifice (11) outside the reservoir (1). The heating element (6) further contains at least a first longitudinal duct (22c) and at least a second longitudinal duct (22h), communicating with each other through a passage (35) formed at the heating element (6) end located inside the reservoir (1) and communicating respectively with a cold water inlet (27) and a hot water outlet, provided at the heating element (6) end located outside the reservoir (1) and capable of being connected to a hot water circuit.
Abstract:
A water heater system includes a primary heat exchanger including a tank and at least one flue, and a secondary heat exchanger including a core and a flue gas flow path. The water heater is operable in a heating mode in which a combustor produces hot flue gas and a water pump flows water through the core of the secondary heat exchanger and into the tank, and in a non-heating mode in which the combustor and the water pump are inoperative. The flue gas flows from the combustor through the at least one flue to heat the water in the tank and then through the flue gas flow path to heat water in the core before being exhausted.
Abstract:
A hydro-furnace for an RV includes a housing, a water inlet and a hot water outlet accessible through the housing, a radiator tank inside a radiator compartment of the housing, a heat exchanger inside a burner compartment of the housing for heating water flowing therethrough, a burner inside the burner compartment to provide heat to the heat exchanger, a heater core inside a recirculating compartment of the housing or heating air flowing therethrough, a blower inside the recirculating compartment for pulling return air through the heater core and delivering heated air outside the housing, and a pump circulating water from the radiator tank through the heat exchanger, through the heater core, and back to the radiator tank.
Abstract:
An incinerator (10) comprising: a combustion chamber (12) and a flue (22) in fluid communication with the combustion chamber (12); a primary gas-to-gas heat exchanger (24) associated with the flue (22); a secondary gas-to-liquid heat exchanger (36); means (34) for forcing a supply of air (52) through the primary (24) and secondary (36) heat exchangers; and a heat sink (40, 42, 44, 46) adapted, in use, to capture heat from the secondary heat exchanger (36). The provision of a primary gas-to-gas heat exchanger (24) associated with the incinerator flue (22) means the problem of water boiling in a gas-to-liquid heat exchanger is overcome. By controlling the means (34) for forcing a supply of air (52) through the primary (24) and secondary (36) heat exchangers, the amount of heat recovery can be adjusted.
