I am about to buy a copper cylinder for my farm house
I am going for an indirect cylinder 1200x450 but just as i had found the best price i noticed some of the cylinders had s r (secondary return ) written in the description can anyone tell me what the difference is please and which one do i need for a conventional heating system. ie oil boiler heating water in cylinder and radiators
