I didn't get caught flat footed, but I've certainly defined some weaknesses that I need to improve upon.
I'll be adding a 50A Reliance 10 circuit transfer station, so I can hook my welder /generator (9,500/10,000 peak) up to the house if needed. I have propane heat, water heater and cook stove. Although the furnaces need electricity for the fans and oven needs it for the controls. I need to map my breaker box, this is a 50 year old house and has been changed over the years so the breaker box has 24 circuits. I'll need to define the 10 I need and will include the furnaces, well pump, fridge, chest freezer and probably the addition that has a 1.5 ton A/C. With gas on the main appliances, my electrical needs are actually pretty low.
My well house froze up when we got to the coldest temps (-3 degrees), partly due to the rolling outages. But I did find some insulation and heat trace deficiencies that I'll remedy. I'll also find a small portable propane heater to put in there (a little buddy will work just fine, if I keep a supply of 1 lb bottles). I need to streamline some of the piping and add some drains so I can isolate and thaw sections.
Some of my freeze proof hydrants aren't deep enough. I new this already as most of my yard lines (pre-existing) are barely 6 inches deep. It seems the cold was able to transfer down the hydrant and freeze at a tee or elbow.
I'm on a pier and beam foundation and didn't suffer any pipes freezing under the house, but we were pretty good about keeping faucets dripping.
My in-law apartment (separate building) will need some supplemental heat. I'll get a Big Buddy heater for there and run it off the big bottles.
Gasoline supply was an issue as I have few things that actually run on straight gas, with the exception of my welder/generator and a pressure washer and I don't normally keep much around. The welder/generator actually burns a fair amount of gas when it's generating. I'll have to get some extra gas cans and fill them before an "event". 25 gallons or so should suffice. I can pour them in the car fuel tanks if they're not needed.
