Page 23 Utility side Buffer tank Mixing valve Circulation pump On-board desuperheater The bulb of the 3-way mixer valve is placed at the de-superheat- er exchanger inlet. By mixing the hot water produced by the recovery with colder water from the tank, it reduces the time needed for the system to reach full operating capacity to a few moments.
