Hi,
We have a four level house in Brooklyn. Previously the house was heated using cast iron radiators (many new) connected to a boiler in the basement. This is two family home (two floors per apartment) and we have recently instated a new combi boiler in the top apartment. It is providing hot water to the bathroom etc but we have yet to hook to a heating system. It seems a waste to do away with the existing radiators. The radiators are located at the front and back of the house (the building is connected on each side). There are four radiators per floor (2 front, 2 back) for a total of eight.
My question is, if we run new lines to the existing radiators (PEX with oxygen barrier) should this be done in a home run system or in a loop? The boiler is in the middle of the house 15 feet from the front and back walls. If we do home run can it be to a manifold at the front and a manifold at the back? Pipe sizing suggestions?
Any advice appreciated.
Thanks
