Neither of our vehicles would start this morning. Killed the batteries very quickly trying. Don't own a booster or charger, hoping we can find a neighbor who does. Not a huge deal for me. I work outside, so I wasn't going to be working either way, but wife can't miss work again tomorrow. Furnace struggling to keep up. The furnace is brand new last May, but the house is 141 years old. We've replaced windows and siding and beefed up the insulation over the last few years. But, the exterior walls are only 4 inch, so they can only be insulated so well, and most of the ceilings are cathedral style, without modern insulation space. Some areas of the house also don't have crawl spaces, so I can't insulate those floor systems until we tear up and redo flooring in the next year or two. Even with 2 space heaters and electric fireplace, the furnace is still running non stop. Managed to keep the pipes from freezing. But only by keeping the furthest faucet dripping, and setting an alarm overnight to run the bathtub and toilets every two hours. This is defintely the coldest sustained period I can recall. It's been an adventure. Not all bad though. We've been able to do some fun extreme cold weather science experiments with the kids.
