I have a older house that has the boiler in the celler and baseboard radiators in every room. three years ago I purchased and installed myself a new boiler. the way the older system was installed was a large loop starting in bedroom then going complete around the house back into the boiler..the house is always heating unevenly. hot in the first room..and getting cooler as it loops. I'm thinking about redoing the hole system but I'm not sure I have it correct. my Idea is to start a 1 inch copper pipe down in the basement and at every room put a 'diverter valve' ?? with 3/4 copper up to the baseboard then back down to the main pipe. do this for every room with a baseboard. is this the way it should be done? do you think it would help with the uneven heating. any other ideas ?
thank you
