In a real emergency they suggest making a tent like structure in one room such as blankets over a table to minimize the amount of air space needed to heat. Fall sailing I find that wearing a hat and wool socks to bed goes a long way to keeping warm. Be careful of hypothermia even in your testing. You may not actually be aware of how your body is reacting to the test. Stay safe.

as low as 48 degrees where I sleep in the winter, and dress for it--- over the past five years
when I have been very frugal with winter heating--

and the 40-degree minimum furnace setting will prevent the basement temperatures,
where the water-pipes are, from getting as low as 32 degrees...

It has been getting rather cold the past few days,
but I've never felt cold in the morning--- before I got out my blankets, LOL

I'll be fine, but thanks for your thoughts!


However, I might break out my short stories by Jack London.....

The travel restrictions and the fear of not being able to get the boat off the water if necessary was too great. For the first time in 20 years it looked like I would spend the summer in the house. I started to feel like I would need fresh air to survive. In July we put a tent on the screened porch to avoid drenching thunderstorms and began sleeping outside seven nights a week. As fall came the evenings still felt good but by the end of October it started getting pretty chilly. I lasted in the tent until the end of November. My friend stayed out there another three weeks. It sounds weird but we found taking a hot shower before going out to the tent made getting to sleep easy. At 32* I began to feel it. It was so nice to hear the owls and coyotes that I hated to come inside but I drew the line at head under the sleeping bag and my nose feeling frozen!

I wish the best for you and your experiment. I understand where you are coming from. Be careful with the karosene heater inside. Carbon monoxide. Take care! My best to you.

especially in such small quantities..... it's just one lantern, not a larger heater...

and I haven't even broken it out again yet this year....
