Thanks to all for looking- I just signed up for this site after hours and hours of reading your great posts! However, I still just cannot make up my mind as to the best way to connect my 800 gal outdoor concrete storage tank. Everyone has a different way of how they did it, but I just could not find one that fits my "needs".
I have an E-Classic boiler and I just dug out a hole, 8' deep for the tank (I have absolutely no room in my house for it). I put the tank in ground, lined the entire outside w/ 6" of foam insulation (I figured the depth should help with insulation as well- inside will be lined w/ 2" of the heat resistant foam & EPDM when it arrives). My question is: what is the best way to run this storage tank to my current closed pressurized boiler system (which is exactly 90' away from tank)? I will be using a HX at the oil boiler inside my house no matter what because I obviously want to keep that system pressurized. The wood boiler will be an open system. An idea someone gave me was to run 100-150' of 1' pex from the return line from the house and right into the concrete tank. The supply line will be much shorter and run through the tank as well, but more heat will be going into the indoor oil boiler first. Our domestic hot water currently is heated from our boiler.
Will this 1" vapor barrier pex line be sufficient enough for heat transfer? If so, how much should I use (I have 300' roll left over). Or should I just use heat exchangers in the tank? The line I will be running is the 4" pipe fully insulated w/ foam w/ 1" supply & return inside it. I really need to get this done quick since my boiler has already been running for about 3-4 days now! Spent over 10k on boiler this spring and with the jobs we had this year, I just am getting to it. I would like to see a return on this investment so I got to do something quick.
Any advice offered will be much appreciated. Again, I learned more from this site in 6 hrs than I have in probably a year! Thanks again guys!
BTW, I'm not an expert in plumbing or hydronic heating so If I said something that makes no sense at all, please feel free to correct me
