Can a shed (20m2) be equipped with heating?

or a simple wood stove. But everything except underfloor heating has the disadvantage that it is cold from below. Depending on what he wants to do in the shed, it will become unpleasant very quickly

Do you really need that? I have 3 unheated garages, one of which is a workshop (including circular saw, workbench, etc). When I work there in winter, I put on my fleece jacket and that works without any problems. I would save myself the effort or put in an electric fan if you are a frostbite.

Build a shed with solid 4cm thick wooden boards. Then insulate the walls very well with Styrofoam and cover them with thin boards. A small infrared heater with electricity is completely sufficient for you. I would never run a line from the house there.

When considering a wood stove idea, keep in mind the distance of the shed to the neighbor: boundary buildings are not allowed to contain any heating appliance!

Correct, moreover, a heating appliance must be approved. I want to see the chimney sweep who approves something like that in a wooden hut.
