New construction. 3,000sq. ft house. We had antifreeze added by the heating contractor to the hot water system. This hot water runs off the boiler. In doing final
inspection my husband drained some of the water out of the boiler. It came out clear. and dried right away on my hand.
Put it in the freezer and within 2 hrs it had frozen, not solid but definitely frozen.
Can anyone give me information about this so that I can go back to the contractor armed with some knowledge. Thank you.
