Room heater for power cuts

I can't help with information about heaters, I'm afraid. However, we do have a small camping stove that runs on small cylinders. Its a little bigger than a laptop, and thicker, but easy to handle. When we get a power cut we can at least boil water for a hot drink or a hot water bottle. They're not very expensive - less than £20 - and we've found ours really useful.

Should add that when I was young and fit the calor gas cylinders were heavy . If I needed one now I would get two and make sure our handy man lugged them in and used one at a time if you have the space.

We used to have a gas fire on wheels with portable calorie gas in the back. This was in the days before we had gas and the solid fuel central heating was a nightmare. It was always out overnight .
