The present invention provides a method of operating a gas heater for water including the steps of: restricting a water flow to the gas heater; determining a first rate of a first gas heating for the restricted water flow; adjusting the gas heating to the restricted water flow; repeating the previous steps until a heated water has a temperature above a temperature threshold; removing the restriction to the water flow to increase the water flow; and determining a second rate of a second gas heating for the increased water flow. The present invention also provides a gas water heater which utilises such a method.

Gas heater for water and a gas water heater

A method of controlling a temperature of water delivered by a water heating system, includes providing communication device which is adapted to receive a communication from at least one mobile device, the communication device being located so as to determine when the at least one mobile device is within a predefined zone in which is located a pre-selected water access point. In response to a determination that the at least one mobile device is within the predefined zone, enabling a user selecting a temperature setting of the where the water heating system. The selection is wirelessly communicated to a receiver which is in communication with the water heating system.

Location based temperature limit control for a water heater

The present invention provides an outdoor water heater () having a lower chamber () located in a cabinet () which substantially sealingly encloses a naturally aspirated or natural draught burner, a combustion chamber, a heat exchanger (), a flue () for conveying combustion gases from the burner (), the flue () extending away from the heat exchanger () and passing through a middle chamber () located above the lower chamber (), the flue () not opening into the middle chamber () and opening into an upper chamber () which has two opposed openings (), the upper chamber () and middle chamber () being substantially sealed with respect to each other to prevent combustion gas flow between the middle chamber () and the upper chamber (), and wherein the middle chamber () has divider formations () separating one side of the middle chamber () from an opposed side of the middle chamber (), whereby the divider formations () direct air flowing from one side of the middle chamber () to pass downwardly into the lower chamber () on one side then upwardly out of the lower chamber () to exit the middle chamber () on the other or opposite side.

Flue arrangement

A water heating system having a system inlet pipe (), a hot water delivery pipe () and a hot water return pipe () connected to a building hot water distribution network (); the water heating system including one or more water heaters (), the or each water heater having a heater inlet () and a heater outlet (), a hot water return pipe () connected between the system inlet and delivery outlet via the building hot water distribution network to form a close loop hot water supply-return circuit; a pump () connected to circulate water through the hot water supply-return circuit whereby the pump can circulate water through one or more of the water heaters; a valve means () a first non-return valve adapted to prevent inlet water (water delivered to the system inlet) from flowing into the hot water return pipe or the building hot water distribution network.

Circulating hot water system and or appliance

A water heating system having a system inlet pipe (), a hot water delivery pipe () and a hot water return pipe () connected to a building hot water distribution network (); the water heating system including one or more water heaters (), the or each water heater having a heater inlet () and a heater outlet (), a hot water return pipe () connected between the system inlet and delivery outlet via the building hot water distribution network to form a close loop hot water supply-return circuit; a pump () connected to circulate water through the hot water supply-return circuit whereby the pump can circulate water through one or more of the water heaters; a valve means () [a first non-return valve] adapted to prevent inlet water (water delivered to the system inlet) from flowing into the hot water return pipe or the building hot water distribution network.
