    摘要: A water heater includes a heat exchanger. A controllable three-way proportional valve provides a proportionally controllable flow to the hot water inlet of the heat exchanger and a boiler return water outlet. A mixing tank mixes a cold water and a hot water. The mixing tank provides a time delayed mixed water. A temperature sensor is disposed in or on the mixing tank to measure a temperature of the time delayed mixed water to provide a time delayed mixed water temperature. A feedforward control process running on a processor adjusts a proportional operating position of the controllable three-way proportional valve to regulate a temperature of hot water at the hx domestic hot water outlet based on the temperature of the time delayed mixed water temperature. A method for controlling a hot water temperature of a water heater a water heater using a flowmeter based feedforward control are also described.

    摘要: A heat exchanger cabinet includes a base pallet. A heat exchanger base bracket of a selected fixed height or of an adjustable height bracket provides a support for a bottom of a heat exchanger, such that regardless of a height the heat exchanger, and within a range of different heat exchanger heights, a plurality of top mounted fluid inlets and outlets of the heat exchanger are disposed at about a same height above the base pallet. A set of heat exchanger base brackets, a stackable heat exchanger base bracket, a heat shield for a heat exchanger cabinet, and a heat exchanger cabinet for a vertically mounted heat exchanger are also described.
