Thinking about adding heat pump,do I need to put a by pass

in line to avoid heater when I`m not using it?

Or is it all right to put it inline after filter and before

SWG all the time?

The latter is much easier and staight forward,but with the water flowing thru it allways damage the heater.

I planning on using Aqua Pro.

Does anyone have pictures showing by passed heaters?

Thanks...JR
