Abstract
A water heater system includes a boiler having a supply port, an output port and a recirculation input port. A heat exchanger includes first input and output ports, and second input and output ports. An averaging tank has an inlet and an outlet. A first fluid flow subsystem is for controllably directing water along a primary loop through the boiler and from the output port of the boiler to the input recirculation port via either a first path through the first ports of the heat exchanger or a second path bypassing the heat exchanger. A second fluid flow subsystem is for directing water along a secondary loop through the second ports of the heat exchanger, through the inlet and outlet of the averaging tank, and back to the heat exchanger, whereby water directed through the secondary loop is heated from water directed through the primary loop via the heat exchanger.
