<p>For those used to it, it’s not an issue. Keeping the pipes from freezing by leaving taps open a bit is the prescribed method. Make sure the drain is open. If it’s an extended period, and you have a bathroom over an unheated area, the drain elbows are also susceptible to freezing. Pour a bit of RV non toxic antifreeze (or use regular automotive antifreeze if you have to) in the toilet and tub. If the water is left running in the sink, don’t bother. The movement will keep the drain trap from freezing.</p>
<p>A fireplace (properly inspected and cleaned) will easily heat a room. If you must, everyone curls up there in blankets and sleeping bags. Tropical fish, reptiles, small mammals kept as pets with in tank heaters need to be covered with a couple of blankets to maintain existing temperatures as long as possible, but be aware you may well lose them over an extended outage. </p>
<p>Used judiciously and in conjunction with an battery operated CO2 detector a propane camping lantern will throw out a good amount of radiant heat. I am NOT advocating the use of a propane or catalytic camping heater in an enclosed environment, but IF you must, place it in the fireplace firebox, with the flue 1/2 open, and use only in conjunction with a battery operated CO2 detector.</p>
<p>Refrain from opening and closing the fridge or freezer maintaining the cold as long as possible. With luck, all you’ll lose is some ice cream. If it’s really cold, stick the frozen food outside in a cooler or two.</p>
<p>Those with well pumps are out of luck. There always should be a supply of drinking water on hand or prepared prior if the power is expected to go. For flushing, you’ll have one flush in each toilet tank, and that’s it. Again, a full bathtub and a bucket can be used to flush as required. </p>
<p>Existing hot water in the holding tank will last a while, depending on your system. Use it judiciously. </p>
<p>We have a generator, firewood/fireplace and below zero sleeping bags. We’re talking Dante’s ninth circle before we ever hit a hotel. :D</p>
