Radiant Floor Heating/1958 copper radiant not working



Our lower level has radiant heating embedded in a concrete slab.  House was built in 1958 so I assume tubes are copper.  The lower level has 4 rooms.  The heat is not working in one of them (kitchen).  We are also having a problem with our kitchen faucet cold water and we are working to warm those pipes.  The outside temperature has been in the 20s or below for about 3 weeks, sometimes in the single digits. I have turned up the heat, hoping it will spread through the floor of the other rooms to the kitchen and warm up the blockage in the kitchen.

What other tactics should I try at this point?

If I am not successful, how do I go about finding a qualified professional in my area?

Thank you,

I think you are on the right track. If you believe the cold potable is frozen try running the hot at a slow, just-past-a-drip, pace over night. Turn the oven on, crack a window if you burn gas, broil if you have electric and wait...

Pull floor covering away from outside walls and use space heaters where you think you may have a frozen pipe.

Don't set your thermostat back in cold weather since this is the perfect time to freeze something up.

As for finding a contractor; calling for radiant help is probably your best bet.

When you think you have a frozen pipe remember; it is easier to keep up than catch up. Turn everything on, lights, oven, boiler and squeeze the cat. Whatever it takes.
