Under-bed fireplace.

A thermal mass wood heater that just happens to be hidden under the bed.the more than 5 ft deep narrow fire box suggests that it was designed with automatic ash removal a blower for combustion and lots of mass to heat up. once that is done she probably would allow the fire to die out.

Most likely you’d feel like a piece of toast in that bed! I live in New England where the nights get cold. We don’t heat our bed room so we rely on our electric blanket to keep warm. If we had to do this each night it would be a huge amount of work! We don’t understand how spoiled we are here in the States!

I just turn up the central heating.

The girl is dressed not so heavily to be severe climate, but it's not Ventura, Scottsdale or Palm Springs either.
The wall has an interesting feature; with two sets of casement windows a ~foot apart. There are plants on inner sill, effectively a green house adapting serious depth of 'dual glazing'. You know why such depth is chosen....time comes, big enough to enter and clean.
What ever climate, I think Frank S's interpretation is close. Radiant heat's best heat of all. Who thinks the thermal mass [heat battery] is probably stone, cement, tiles etc and heats that water bed? 90°F [32°C] would be ideal. Never thought corn stalks as a source of fuel, but this firebox accommodates particular shaped and plentiful material.

Brings new meaning to the phrase “a hot bed”.

This is like the opposite of a bedjet or bedfan or related new inventions; these would be easy to make.

They call it maise ing "hot stuff". We are really lucky indeed. (Under Bed Fireplace post).

I believe that the Chinese have been using this method of heating house floors and beds for thousands of years.

It's known as a "kang" and they date from as early as the first century. Lots more here...
