I’m looking into having either a Rheem 266k or and Pentair 250 pool heater installed. Wondering if anyone has a preference between these 2. I have all pentair equipment right now but I’m not sure if that matters. Any insight is appreciated. Also, does pool water always run through the heater even when it’s not on?

Both are good and both can have problems if not regularly maintained and used.

They are both controlled the same way with your ET system. Read Heater Control with Automation - Further Reading

Are you going to DIY the installation or use a service?

I would buy whichever one you feel will be supported best locally.

Also, does pool water always run through the heater even when it’s not on?
Yes, unless you install a manual heater bypass which I recommend you do.
