Hi boyz, I need help with a remodel question. I am currently renovating a old farmhouse from 1940. The home has a boiler with baseboard heat with 3/4" copper fin ( I think thats what you call it). I want to run heat up to the second floor. There is 3 bedrooms upstairs that never had any heat to them. I have multiple walls gutted out and have 3/4 O2 barrier pex piped up there. I need some clarification on the exsisting system. Is radiant baesboard what I have or would it be considered panel rads? Is the current system 180 degree water or low temp? I dont understand the difference between the delivery of the two systems? Which will work the best for me? The pex comes up into one room and will convert to copper into a 8' baseboard ,then go out of that baseboard and through a inside wall into the second room and into another 8' baseboard. I think this is considered Series piping? Any help would be appreciated.
