Thanks for your kind reply, Unique. I hadn’t seen your reply until led here by the Texas cold snap headline. Your suggestion for hand and foot warmers is an excellent one, and I’ve ordered a large box. I’m also ordering a fireplace fan on your other excellent recommendation. Which should help a bit with my basically heat-up-the-chimney style fireplace. A propane space heater, on the other hand, gives me the willies even with a CO detector and a fire extinguisher in the house. Another forum on this site talks about using a backup battery and an electric blanket to deliver warmth to where it’s most needed. I’m looking at products such as the Jackery and some sort of solar panel for my south facing balcony. I think The Prepared are going to run a review of current options (pun intended) and I’m quite eager to see it. You guys are truly great!
