converting to pumping away/ cost effective?
Just a little intro. I have no training in hydronics. The extent of my hydronic education is from reading Dan's books. I was by a customer recently and while pocking around his basement I noticed that his hot water boiler has no air eliminator, a circulator on the return and an interesting compression tank set up. There are two pipes coming from the top of the boiler. One pipe is the main. The second pipe has the compression tank and water feed connected to it. If I understand this correctly this is the equivalent of placing the point of no pressure change in middle of the boiler. My question is if it is cost effective for the customer to move the circulator to supply, move the tank to the supply main between the boiler and circulator and to add an air eliminator. I am also interested in knowing which air eliminator the knowledgeable wallies would recommend. The boiler is a40k unit with one zone on a small addition to the house. The customer complains of cold and of always hearing water running. I have thoroughly read pumping away. GREAT BOOK! Thanks a ton.
