I live in a typical Boston triple decker. We have oil and radiators for heating. I don't think we have any kind of hot water tank, the only tank I see in the basement is the oil tank. The problem is that when the radiators are very hot to the touch I know I'm in for a cold shower, but if the radiators are warm to cool then the shower is fine.
Is there some kind of valve that could be adjusted so that every bit of hot water is not pushed out to the radiators, to save some for showering?
Thanks,
