What about say 28 degrees for 6 or so hours .....I guess my question is how cold for how long is troublesome? It does not seem practical to to do a full winterization for the occasional cold night. Just worried about when I should be worried
It has gotten cold enough this winter to freeze pipes - definitely. You don't list what you own, so your intent may be misconstrued.
- If you're only concern is freezing, you'll need to consider using the furnace - and in some models the tank heaters. Black and gray tanks can freeze and split and are expensive.
- Using an electric heater will generally work fairly well (use two on a bigger unit), but that won't warm the belly pan or tanks
- If it's truly cold the propane furnace has ducts that go to the tanks
- Newer units often have heat pumps rather than just Air conditioners - these work well down to about 40 degrees F. Most have thermostats that automatically switch to furnace at low temperatures
- older units with copper pipe will get more damage than newer ones with PEX - but even PEX can fail under extreme temps.
If you fulltime, winterizing isn't practical. Always keep enough spare propane to get through the night (mine always runs out at 3:00 AM) and camp where you have electricity, but remember it may fail in an ice storm.
If you don't fulltime, winterize or at the very least drain the tanks, pipes and traps, and use compressed air to blow the low spots out. Don't forget to remove the faucet filters!
