ᐅ Do radiators always need to be installed under windows in new constructions?

Hello,
we are currently planning and looking to reduce costs by replacing the underfloor heating with regular radiators. However, we do not want to place them in front of the windows. This raises the question: Is it necessary in a new timber frame construction to install the radiators below the windows, or is it equally effective to position them elsewhere in the room? The size of each room is under 30 sqm (320 sq ft), and the windows are triple-glazed. We are not building according to KfW standards, but the carpenter mentioned that due to the wood construction, the walls are thick and well insulated.
Do you have any experience with this?

And if you then calculate losing half a square meter per heating circuit—which theoretically means you’d have to build bigger to maintain the same living area—you quickly add another €10,000 to the cost.
Better save on the buffer tank and get exemption from the ERRs. That alone can save you around €3,000 to €4,000. There are plenty of threads explaining how to do that.

@Steffi33 also has radiators and these are really well covered 🙂Yes, we have radiators located in the middle of the room (behind the slats in the room divider). For us, it’s a space-saving solution that provides pleasant warmth during the cold months. There is also a long radiator under the large window in the living room.D

I wouldn’t really call it an “evil”… we are perfectly happy with it. By the way, in the tiled rooms (kitchen, hallway, and bathroom), we have underfloor heating.D
