A water heating assembly, related kit, use and method make use of a temperature control near a point of use of water, so as to reduce a time response for hot water at this point of use are provided. The water heating assembly includes a tank for containing water, an inlet temperature sensor for sensing an inlet temperature of the water upstream of the tank, and a valve located upstream of the tank. The valve is actuated when the sensed inlet temperature reaches a given temperature set-point such that the water is bypassed from the tank and directly sent to the point of use. The water heating assembly is configured such that the point of use can be fed with water at the desired temperature in a reduced time, the water coming directly from the hot water source and/or the water heating assembly, thereby saving water, energy and time.

A water distribution apparatus and method including cold and hot water supplies, a fan coil (or chilled beam device), a control valve having cold and hot water inlets and outlets, cold and hot water outputs configured to supply cold and hot water to the fan coil, cold and hot water return inlets configured to receive from the fan coil the water supplied by the cold and/or water outputs and outputting the cold and/or hot water to the cold and hot water supply lines, respectively, via the cold and hot water outlets, respectively. Cold and hot water is supplied from the cold and/or hot water outputs to the fan coil and received into the cold and hot water return inlets, respectively, and the cold and hot water supplied by the cold and hot water outputs to the fan coil is output to the cold and hot water supply lines, respectively.

The disclosed technology includes a non-powered valve assembly having a valve, an actuating system, and a trigger. The trigger can be in mechanical communication with the actuating system and the actuating system can be in mechanical communication with the valve. The trigger can be positioned such that the trigger can interact with liquid resulting from a leak in a plumbing assembly. Upon interaction with liquid, the trigger can dissolve or expand, causing the actuating system to be activated and the valve to transition from the open position to a closed position. In the closed position, the valve can restrict the passage of liquid through the plumbing assembly such that the leak can be mitigated.

A water heater includes a tank defining an interior space adapted to contain water and a shroud over the water heater and defining a component space inside the shroud. A first pipe nipple is coupled to a spud of the water heater, the first pipe nipple and spud defining a non-collinear axis that is non-collinear with a pipe axis of a pipe to be fluidly connected to the tank. A flexible connector is connected at one end to the first pipe nipple along the non-collinear axis. A second end of the flexible connector is positioned collinear with the pipe axis. A second pipe nipple is coupled at one end to the second end of the flexible connector and coupled at an opposite end with the pipe. Fluid communication is established between the pipe and the interior space of the tank through the pipe nipple and flexible connector.

A heat trap apparatus for a water heater is provided. The heat trap apparatus includes a tubular body, a liner disposed within the tubular body, and a heat trap baffle assembly having a tubular housing coaxially disposed within the liner. The liner includes a projection to engage with an inner surface of the tubular body at a first end using an interference fit. The tubular housing includes a first diametric portion to engage with the inner surface of the tubular body at a second end using an interference fit, a second diametric portion extending from the first diametric portion and to engage with an inner surface of the liner using an interference fit, and a third diametric portion extending from the second diametric portion and to movably support one or more heat trap inserts to inhibit convective fluid flow therethrough.

A heat trap apparatus for a water heater is provided. The heat trap apparatus includes a tubular body having a length defined between a first end and a second end, a liner disposed within the tubular body, and a heat trap baffle assembly having a tubular housing coaxially disposed within the liner to inhibit convective fluid flow therethrough. The liner has a length greater than the length of the tubular body and has an outer surface engages with an inner surface of the tubular body using an interference fit. The liner includes a first end engaging with a peripheral edge of the first end of the tubular body and a second end extending beyond a peripheral edge of the second end of the tubular body for a desired length to connect with a conduit.

A water distribution apparatus and method including cold and hot water supplies, a fan coil (or chilled beam device), a control valve having cold and hot water inlets and outlets, cold and hot water outputs configured to supply cold and hot water to the fan coil, cold and hot water return inlets configured to receive from the fan coil the water supplied by the cold and/or water outputs and outputting the cold and/or hot water to the cold and hot water supply lines, respectively, via the cold and hot water outlets, respectively. Cold and hot water is supplied from the cold and/or hot water outputs to the fan coil and received into the cold and hot water return inlets, respectively, and the cold and hot water supplied by the cold and hot water outputs to the fan coil is output to the cold and hot water supply lines, respectively.

A hybrid tank and tankless hot water system with an inlet bypass and an outlet bypass are configurable between a hybrid heater configuration and an on-demand configuration. In the hybrid heater configuration, the inlet bypass supplies cold water to a cold water inlet of a storage tank and the outlet bypass supplies hot water from an outlet manifold to a recirculation inlet of the storage tank. In an on-demand configuration, the inlet bypass supplies cold water to a cold water manifold for directly providing cold water to hot water heaters and the outlet bypass supplies hot water from the outlet manifold directly to a system hot water outlet. In the bypass configuration, a storage tank and/or recirculation pump are fluidically isolated from one or more hot water heaters to facilitate their maintenance, repair, replacement while still supplying hot water on demand from the hot water heaters.

Provided is a hot water barrel structure for a water dispenser, the hot water barrel structure including: a hot water barrel having a water reservoir therein; a partition plate provided in the hot water barrel and dividing the water reservoir into an upper water reservoir part and a lower water reservoir part; an inlet pipe supplying water that is to be heated to the lower water reservoir part of the hot water barrel; a heater provided at the hot water barrel and heating water introduced to the lower water reservoir part to produce hot water; and a hot water pipe provided at the upper water reservoir part of the hot water barrel.

A heater with a recovery device for swelling water is provided. A water inlet pipe and a water outlet pipe are longitudinally provided on the heater. The recovery device is transversely disposed on the heater and connected with the water inlet pipe, such that the recovery device is coupled on to reduce the entire size. The recovery device is adapted to recycle and store the swelling hot water in the heater so as to provide an energy-saving effect and to stop water from dripping.
