so I'm wanting to make a towel warmer out of copper. I have 2 copper stubs sticking out of the wall which has pex hooked to those running down to my garage. I have a box in the wall that has a cat 5 running to the garage also. My manifold for the radiant heat is in the garage also. My thought was to somehow hook the lines up to the boiler and have a pump circulate the water when the timer was on. Thought maybe a 12 volt transformer for the pump. Any suggestions, pics would be great!
