Heating costs basically depend on the quality of the insulation (walls and windows), regardless of the type of heating. However, the type of heating affects comfort. The most comfortable heating, however, is ceiling heating. It has been proven to produce the most even temperature distribution from floor to ceiling. I installed one in 1972 and am 100% satisfied. How does it work? The ceiling warms up to 30 - 40° depending on the heating demand. It then radiates heat throughout the entire room with so-called low-temperature radiation. Walls, floor, and furniture are evenly warmed. In contrast, floor heating has the disadvantage that a large part of the surface is covered with furniture, so the heat cannot escape there. To deliver the same amount of heat into the room, its temperature must be higher. This can cause burning feet.
