Patent attributes
A durable water heating system providing rapid hot water delivery includes a water heating unit connected to a water source. A hot water line connects the water heating unit to at least one water delivery fixture. A return line of substantially the first cross-section connects to the hot water line adjacent the water delivery fixture located at a greatest distance from the water heating unit. A flow velocity reduction device has a first end, a second end, a first cross-section, an aperture and that extends from the first end to the second end. The aperture and has a second cross-section smaller than the first cross-section. Attachment fittings are provided adjacent the first and second ends. When the device is installed in the return line, velocity of water circulating through the system will be substantially reduced, thereby reducing wear on the system while providing rapid hot water delivery at the fixture.
