Hello all. I've searched for an answer to my question with no luck so I've decided it's time to start a new thread. I'm removing three radiators from my second floor so I can pull up and install a new hardwood floor. My radiator system is defiantly a hot water one and all the radiators in the house look normal except one. Normally both water lines, one going into the radiator and the one coming out, are connected at the bottom of the radiator. However, one of mine has the return line, or what I'm assuming is the return line, connected at the TOP of the radiator. I have yet to come across anything with a similar connection and I don't know if I should leave it like this or change it. The radiator seems to work fine with good heat coming off in the winter and does make any noise.
Does anyone have any info on why it would be connected in this way?
