hey guys i have been on this site for a while mostly looking around not posting much. i do have a question though. i will start by telling you about my system. i have a wells mclain oil boiler with a new yorker wc-90 add on wood boiler. i have 4 zones all on taco circulators and i also have a taco pump that circulates between the wood boiler and oil boiler. everything works great but i do not like the way my dump zone is set up for a power failure. currently i have an automag teed off the supply side of the wood boiler connected to my bedroom zone. when the power goes out the automag opens and it is supposed to thermosiphon through that zone but it doesnt do a very good job of cooling the boiler off in the evemt of a power failure. i have come across some old baseboard that i would like to use instead of my bedroom for this dump zone. i want to install it above the boiler so it will gravity feed. my question is really about the plumbing i know i need to tee on the supply side of the wood boiler with the auto mag but what about the return side?? my circulator that works in between the oil boiler and the wood boiler has a check valve and it is right on the outlet of the wood boiler so there is no room to tee it in before the pump. i am thinking, correct me if i am wrong that if i tee it in after the circulator that it wont flow right because of the check valve. there are a couple of threaded plugs on the bottom of my boiler, couldnt i just connect the return side of my dump zone to one of these outlets so that when the power went out and the automag opened it would thermosiphon through the base board and back into the boiler. i just keep thinking that with the check valve in the pump it is not going to allow water to move out of the boiler. sorry for the long and confusing post but i am want just a little piece of mind when i load my boiler up and go to work.
