I am plumbing my domestic hot water heater with a sidearm heat exchanger and i am wondering where do I put the aquastat and what type of aquastat would serve this purpose. I have a A419 Johnson control for the boiler. Should I get another one?
OH I see it looks like you are feeding your existing DHW Tank. If you are piping a loop. Feeding the tank into the bottom and back again pulling from the top with the flow not being continuous by the pump, you would need a open on temp rise set of contacts referencing it at the tank. Probably no tapping's. hh:
I was going to place a tee where the drain comes out of the bottom of the tank. In that tee I would thread a A419 aquastat. Does this sound like it will work?
