    I have not heard of a SunnyBrook using a mixing valve. SunnyBrook usually uses 3 valves on the back of the heater. You have the top and bottom open and the by-pass valve closed during the Summer. To winterize you close the top and bottom and open the by-pass.

    I do know there is a system with a mixing valve, but just not seen SunnyBrook use it.
