DIY water heater setup to heat tank

Nice build. Keeping an eye on this thread for future use. I'd place the temp probe in your display since that is the water volume whose temperature you are wanting to maintain.

Thx much... following.

Can i run the closed loop heating system from any hot water line in the house or does it have to tee off the hot water pipe at the heater itself? Thx
