| 20120125269 | HEATER - A heater, comprising a fuel burner, a primary heat exchanger, and an enclosure around the fuel burner and primary heat exchanger and defining a gas flow path, wherein the enclosure further comprises a secondary heat exchanger and/or heat storage means. | 05-24-2012 |
| 20110162824 | HEAT RECOVERY APPARATUS - A heat recovery apparatus comprising a vessel having: a first liquid flow path such that a first liquid can pass through the vessel between a first liquid inlet and a first liquid outlet; a second liquid flow path in thermal contact with the first liquid flow path; and a heater for occasionally heating at least the liquid in the second liquid flow path on an occasional basis. This allows Legionella growth to be inhibited. | 07-07-2011 |
| 20090314464 | HEATING SYSTEM - A heating system in which a warmed fluid is circulated through a delivery network space heaters to provide space heating, further comprising a thermal store and means arranged to circulate the warmed fluid through the thermal store during a heating shut down sequence to recover heat from the warmed fluid. | 12-24-2009 |
| 20090277618 | CONDENSATE HEAT EXCHANGER - A condensate heat exchanger is provided for recovering heat from condensate draining from a condensate boiler. | 11-12-2009 |
| 20090272340 | Flue, and a Boiler Including Such a Flue - A flue offering reduced pluming is provided, the flue comprising a flue pipe for carrying flue gas and a liquid collector adapted to collect condensation from the interior of the flue pipe and to shield it from the flue gas. | 11-05-2009 |
| 20090090310 | Heating System - A heating system comprising a fuel burner in co-operation with a primary heat exchanger, a reservoir for storing warmed water in, and a blending valve, and a controller wherein in use a user can signal to the controller to warm the water in the water store using a heater or by the primary heat exchanger, and when hot water is required water is removed from the water store and mixed with water from a cold main prior to being or after the water from the cold main has been admitted to a further heat exchanger for heating the water. | 04-09-2009 |
