A bracket to retain an expansion tank in conjunction with a water heater tank may comprise an upright member that extends along the side of the water heater tank and a horizontal member that extends along the top of the water heater thank when the bracket is installed, such that the horizontal member is gravitationally retained against the top of the water heater tank. Straps may be used to retain an expansion tank to the upright member. Magnets, retention straps, and/or legs may be used to retain the bracket in position relative to the water heater tank. Straps, extensions upon which an expansion tank may rest, and retention mechanisms may be used to retain an expansion tank in a bracket.

A hot water storage arrangement having an electronic control unit, by means of which various modes of operation of the storage arrangement can be set. Those modes of operation can represent a normal mode of operation (at a setpoint temperature of between 30 C. and 100 C.), a frost protection mode of operation (at a temperature <10 C. and >1 C.), a time switch mode of operation (in which it is possible to set times of different setpoint temperatures with an adjustable time switch), an ECO mode of operation (in which an electronic temperature limit of between 30 C. and 55 C. is set), a hygiene mode of operation (in which a periodic increase in temperature of 55 C. is set) and/or and run-dry detection mode of operation (in which a temperature difference between a first temperature and a second temperature after heating of the hot water storage arrangement is ascertained).

Exemplary embodiments are provided of combined heater and accumulator assemblies. In an exemplary embodiment, an assembly generally includes an enclosure including a first portion, a second portion, and a divider between the first and second portions. The assembly also includes an inlet through which coolant may enter an interior of the second portion, and an outlet through which the coolant may exit the interior of the second portion.

Water dispensing apparatus comprises modular components including but not limited to an easily accessible water heating module and a water cooling module. The water dispensing apparatus further comprises a bracket for holding at least one of a valve and an expansion tank onto a hot water tank for easy removal of the same in case of repair or replacement. Moreover, the expansion tank comprises a check valve that opens to allow heated water to flow thereinto and closes after heated water has drained therefrom.

A plumbing system pressure protection valve assembly that utilizes a unitary body to connect a hot water tank to a cold water supply, a vacuum breaker, and an expansion tank. The assembly includes two ball valves coupled to the unitary body to isolate the hot water tank from the cold water feed and to isolate and permit draining of the expansion tank. The assembly also includes a rod and foot coupled to a tab on the unitary body to provide support for the expansion tank service valve assembly.

A faucet assembly comprises: a water supply pipeline comprising a water outlet pipeline section and a water inlet pipeline section connected to each other, wherein the water inlet pipeline section contains a throat section with smaller cross sectional diameter; a shell made of hard materials and wrapped around the throat section, so as to define a closed space that contains air around the throat section, while the throat section has an opening to the closed space; a flexible membrane wrapping layer made of elastic materials and is hermetically sealed on the inner side of the shell, so that the closed space that contains air has an elastic, retractable and sealed boundary; a heater connected in series to the inlet pipeline section and is positioned in the upstream of the shell along the water outlet direction, to heat the water that is about to flow into the throat section.

Exemplary embodiments are provided of combined heater and accumulator assemblies. In an exemplary embodiment, an assembly generally includes an enclosure including a first portion, a second portion, and a divider between the first and second portions. The assembly also includes an inlet through which coolant may enter an interior of the second portion, and an outlet through which the coolant may exit the interior of the second portion. The assembly further includes a heat source operable for supplying heat for heating the coolant within the interior of the second portion.

An expansion tank wall mount bracket apparatus capable of being mounted in multiple assembly configurations and supporting multiple expansion tanks.

A water boiler comprises an inner tank, an electric heating pipe, and a controller. A lower cover is attached to a mouth of the inner tank. The lower cover comprises an inlet pipe and an outlet pipe, wherein an outlet port at a lower part of the inlet pipe is in communication with lower part within the inner tank. An inlet port of a lower part of the outlet pipe is in communication with an upper part of the inner tank. The lower cover is arranged beneath the upper cover. An upper part of the inlet pipe passes through the upper cover. A cavity is formed between the lower cover and the upper cover. The cavity is partitioned into an upper chamber and a lower chamber by a diaphragm. The lower chamber is in communication with an outer space.
