I have a gas fired boiler with hot water radiators. During a previous renovation I had radiator lines (supply and return) run into a room that was without a radiator. The pipes were stubbed in and individually capped. Now that I am renovating this room I have opted to to forgo installing a radiator as I am installing electric baseboard heat. My question is this: before I close in the wall where these pipes are located should I make a loop between the two lines or can I leave them individually capped? Thanks in advance for any help.
