Woke up to a cold house this morning. Central heater not working. I cycled the breaker and it kicked on but not much heat. Trying not to panic as it's a bit chilly outside. Tried a few things with no avail.
Bundled up on the couch, waiting for normal office hours to avoid emergency call charges it struck me.
Frozen exhaust pipe. Stepped out side and sure as hell, exhaust pipe was completely covered in ice.
Nice and toasty again. :thumbsup:
That reminds me I need to check mine and also the sewer vents freeze solid.
