An isolation mounting arm for use with an expansion tank has a passageway with a first end portion, a second end portion, and a medial portion located between the first end portion and the second end portion with the drain port located at the terminal end of the second end portion. A first tee is located in the first end portion with oppositely disposed first and second ports. A second tee is located in the second end portion, with oppositely disposed fourth and fifth ports. A first valve member is coupled to the first port, a second valve member is coupled to the second port, and a third valve member is located adjacent to the drain port. An expansion tank is coupled to either the fourth port or the fifth port with a plug coupled to the other port.

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.

A valve including: a body having: a first aperture; a second aperture; a first channel in fluid communication with the first aperture; a second channel in fluid communication with at least part of the second aperture; and an outlet aperture; an adjusting portion associated with the body, the adjusting portion providing a stop; a piston in fluid communication with the first channel, the second channel and the outlet aperture; a thermostatic element configured to assist with moving the piston in response to engaging with the stop, the piston being configured to regulate fluid flow from the first channel and the second channel to the outlet; and a return spring configured to assist with biasing the thermostatic element, wherein part of the fluid flow entering the first channel flows along the piston and exits from a portion of the second aperture.

A method for operating a dishwasher appliance includes receiving data indicating a status of hot water within a water heater appliance, receiving data indicating a status for a cycle of a dishwasher appliance, and initiating a start for the cycle of the dishwasher appliance in response to the data indicating the status of hot water within the water heater appliance indicating available hot water.

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.

A water heating system can include a first tank-based water heater having a first inlet line and a first outlet line, where the first inlet line provides unheated water to the first tank, and where the first outlet line draws heated water from the first tank. The system can also include a first tankless water heater having a second outlet line, where the second outlet line of the first tankless water heater provides the heated water to a first heated water demand. The system can also include a first valve that controls an amount of the unheated water flowing through the first inlet line to the first tank-based water heater. The system can further include a controller operatively coupled to the first valve, where the controller controls a position of the first valve based on the first heated water demand and a first capacity of the first tankless water heater.

A connected-type hot-water supply system includes hot-water supply apparatuses connected in parallel and a control means. The control means sets one main hot-water supply apparatus and sub-hot-water supply apparatuses, and performs leveling control of cumulative loads of the hot-water supply apparatuses by setting the main hot-water supply apparatus based on sequential rotation among the hot-water supply apparatuses. The control means includes a failure sign response mode in which it is determined whether there is a failure sign respectively for components of the hot-water supply apparatuses, and when a component of a part of hot-water supply apparatuses is a failure sign component determined to have a failure sign, a main use time of a hot-water supply apparatus having the failure sign component is increased, and the main use time is a main use time of serving as the main hot-water supply apparatus in the leveling control.

Methods, systems, and apparatus, including computer programs encoded on a storage device, for water monitoring are disclosed. A system includes one or more processors and one or more computer storage media storing instructions that are operable, when executed by the one or more processors, to cause the one or more processors to perform operations. The operations include determining with a leak sensor that a water leak is occurring at a property; after determining that the water leak is occurring at the property, determining that a water usage profile of a particular water consuming device matches characteristics of the water leak; based on determining that the water usage profile of a particular water consuming device matches characteristics of the water leak, identifying a water consuming device that is likely leaking; and in response to identifying the water consuming device that is likely leaking, performing a system action.

A joint connects to a hot water source, a toilet tank of a toilet, and a hot water outlet. A set of pipes connecting the hot water source and the joint may be referred to herein as “main hot water pipes.” Water exiting the hot water source into the main hot water pipes is above a desired water temperature. As time passes, however, water that rests in the main hot water pipes may fall below the desired water temperature. Rather than wasting all of the cooled water resting in the main hot water pipes in order to use hot water at the hot water outlet, at least a portion of the cooled water may be used to refill the toilet tank. Therefore less cooled water exits the hot water outlet before fresh water reaches the hot water outlet.
