Thermal bypass valve, where and when to use it

Every few weeks I get quite a few questions on installing a Thermal bypass valve and it has to do with no having a tankless with a pump installed from the factory inside the unit like the Navien NPE A2 model. Even if you have a condensing highly efficient tankless and there is no pump inside the unit you cannot install a bypass valve, there is no way for the unit to see the valve where you install it. A tankless with an internal pump is setup to handle a dedicated return line or a bypass valve and Navien can handle two bypass valves installed on the system. A tankless without the internal pump can only be used with a dedicated return line and an external pump. Grungfos #595926 $69.95 Navien# 30022965A $79.95 As you can see the Navien is only $10.00 more and is able to be cleaned.
