A beverage water heating supply system. A tank stores water while heaters heat the water. The heated water is distributed through a manifold assembly, which has a multiplicity of components, to a coffee brewer water and a hot water spigot which are controlled by independent solenoid valves. The water is filtered before entering the tank and is filtered a second time before leaving the tank to enter the manifold assembly. The tank employs a combination temperature sensing and water level detection circuit probe to prevent over heating and heating when the tank is not full. The manifold assembly includes a pressure release valve, a blowout port backup pressure release valve, an automatic vent valve, a brewer water pickup, a lower hot water pick up, and a pressure compensating flow control for the brewer water. The manifold is quickly connected to and disconnected from the tank with a bayonet type connection without removing any of the connections to the manifold. A lock and release lever is provided for locking the manifold to the tank. Upon removal of the manifold from the tank, a large opening is available for removing the filter from the tank and cleaning the inside of the tank.
