Didn't have heat last night in the part of the house serviced by a new (in the last year) boiler install. Threw another blanket on and decided to deal with it in the morning. According to the temperature readout on the alarm clock, it was 50 F in the upstairs bedroom this a.m., and -5 outside.
So this morning I go down and
look at the boiler - pop out the control thing and it's flashing P00 - which I figure out means no pressure - uh oh. Walk around a bit and notice the drywall and floor are wet near the end of a section of baseboard. ****!
Now the reason that the pressure dropped to 0 is because I turned off the supply to that section a few weeks ago because I was tired of the water heater leaking out of the pressure relief valve. That's another gripe with these guys - they didn't put in an expansion tank and won't come back and do it because it wasn't spelled out specifically in the contract. I bought one, but haven't gotten around to putting it in yet. Don't need the water on to that part of the house yet (under construction) except to back-fill the boiler.
Now the question. I had them put antifreeze into the system when they installed & filled it - contract specs 50/50 mix of some type of food-safe type antifreeze. What temp should that be good to? Should be less then -5F right? The leak is on an outside wall - 2x6 construction, so has R19 between the pipe and outside, and the house was certainly well above freezing.
