Bursted pipes due to freezing are not that uncommon in my area during winter, but generally they do accour in vacation houses that have been uninhabited for months. I could easily prevent that by leaving a couple of faucets to drip constantly.

As for heating, I'm with you in this ragards. I don't mind the cold much, although my SO would have something to say in the matter...

The house itself has a pretty good insulation and, with proper clothing and warm food and beverages, we could easily go on without heating for several days and no serious consequences.

I still wouldn't mind having that type of woodstove that all families in my region had in their houses, including that of my grandparents, until a few decades ago. It would heat a room but you could also cook on it.

Something along this lines.
