ABSTRACT:
Recirculation hot water system including a fluid delivery system used to supply potable water throughout a home or other facility, having a hot water supply pipe, a cold water supply/return pipe, a hot water heater, a pump, a manifold, a control system, a hot water and cold water faucet or valve, and a demand site (typically a sink or wash basin). The manifold further includes a thermostatic actuator and a check valve. The control means further includes a sending unit, installed in close proximity to the demand site, and a receiving unit, installed in close proximity to the heater. Command signals are transferred, from the sending unit to the receiving unit, via modulated signals that pass through the AC power lines that are used to distribute power throughout the home or facility. The main potable water supply is bifurcated into the hot water and cold water supply pipes with the heater installed in the hot water supply pipe upstream of the manifold, and the pump installed between the heater and the manifold and in close proximity to the heater. The hot and cold water supply pipes are in fluid communication with separate inlets to the manifold. An outlet from the manifold is in fluid communication with a cold water valve, while another outlet from the manifold is in fluid communication with a hot water valve. The manifold is internally ported such that the hot and cold water supply pipes are in fluid communication with each other.
