This is new residential home under construction in Maine. I want to do the initial start up on radiant heat in a frozen slab. The builder wants the heat turned on in the slab only. The 3 other hot water baseboard zones are not ready yet. I want to introduce glycol into the loops. The well water is not turned on because of possible freezing. Any ideas ?
