Yes I guess, I already had my system in place with a wood boiler set up so I did not have a complex setup. I just put a small taco in its own loop from the PRV nipple,I know, Iknow, you are not supposed to use it for anything else, (depends who you talk to) and returned it into the unused cold water supply on the back of the boiler. It is the other orange wire coming out of the upper box in the pics I sent you. It runs 24/7. It is only a 003 and was used in the domestic water loop for the coil in the woodboiler. I probably should have put at least one ball valve in the loop but I used what I had on hand. I will pay the price when I have to replace it!
