Remove and Replace Radiator

go to all of that trouble, can you use a radiator roller? Narrow shaft small diameter roller that can reach behind there? Properly located, the radiator should be at least 2 to 2.5 inches away from the wall anyway. Closer and it increases the heat loss by warming a wall that may not be insulated.

If it is a water system you will have to drain it most likely unless there are sound isolation valves in and out of it or you can isolate and drain the riser.

If steam, you may get away with just closing the inlet valve after the radiator has cooled. The unions can be broken open with a wrench possibly with a helper lever (section of pipe over the wrench handle.)

Either way you are dealing with some residual water.

If in doubt, call a pro.

Makes that radiator roller seem pretty good now, doesn't it?

    Remove and Replace

    I want to remove a cast iron radiator so I can paint behind it. It's probably a simple process to pull it out but what's the best way to mitigate water spills - or will there even be any? Thanks!
