Abstract: A water heating and treatment system includes a water heater operatively coupled to a water heater controller, a hot water outflow line from the water heater, and a cold water supply line to supply water to the water heater. The cold water supply line includes at least one of an anti-scale device operatively coupled to an anti-scale device controller, and at least one sanitation device operatively coupled to a sanitation device controller. The mixing station is operatively coupled to a mixing station controller. The mixing station supplies heated water to at least a first temperature zone at a first hot water temperature. Controllers of the water heater controller, the anti-scale device controller, the sanitation device controller and the mixing station controller are co-located at a front of a single enclosure behind an openable door, the controllers operatively coupled to a supervisory controller.

Abstract: A water heating and treatment system includes a water heater, a hot water outflow line from the water heater, and a cold water supply line to supply water to the water heater. The cold water supply line includes at least one of an anti-scale device, and a UV sanitation lamp. A mixing station supplies a temperature regulated heated water to one or multiple temperature zones. A mixing station supplies heated water to at least a first temperature zone at a first hot water temperature. The water heater, the anti-scale device, the UV sanitation lamp and the mixing station are contained in a single enclosure having at least one sliding transparent wall through which components can be viewed. A plurality of pipe connections passing through a rear panel of said single enclosure are also described.
