Electric wallpaper warming Scottish homes in winter

When the plan is to put a mostly-controlled short circuit into a residential building you presumably want it located where it won’t be subject to damage from footfalls and furniture and stuff.

You certainly can do resistive heating that’s safe as a flooring material; but you’d be talking comparatively massive construction vs. some sort of thin-film sticker thing that isn’t expected to take having a table dragged across it gracefully.

(edit; that said if you take a particularly flexible view of the objective of dealing with poorly insulated housing stock you could treat this property of resistive heaters as a virtue; and almost definitely shouldn’t.)

Indeed, and that’s precisely why adding insulation to the inner side of outside walls is usually A Very Bad Idea. In most cases, it will lead to the condensation point being within in the wall, i.e., water droplets will form (from the humidity in the air) within the outer wall or at the interface of the outer wall and your new insulation, which will cause moulding.
