Doing some maintenance on my system and trying to figure out if I want to change the plumbing configuration.
Current Configuration:
That is the way it was installed, but this means when not operating the solar, the water is still being forced through the solar booster pump. Seems like it shouldn't be like that, but I guess it does prevent the pump from being dry or stagnant.
Alternate Configuration:
This is what I'm thinking of changing it to. Then the Solar loop can be completely bypassed and drained in the winter including the pump and just have to remember to prime it before running in the spring, although barring a failure of the JVA it shouldn't run dry for more than a few seconds. Any downside?
Alternate Configuration 2:
Saw this one online but not sure why it would be preferred.
Any opinions let me know. Thanks.
Current Configuration:
Code:
IN->Filter Pump->Filter->Solar Booster Pump->3-Port Valve---Tee--->Heater->SWG->RETURN
