ᐅ Retrofitting Underfloor Heating: District Heating or Electric?

Good evening,
we want to remove the old tiles in our kitchen (about 18m² (194 sq ft), historic building from 1900, ceiling height 3.60m (12 ft), ground floor) and install underfloor heating. At the moment, we are heating with an old small radiator connected to district heating. A roofer has already inspected the room and advised against a traditional underfloor heating system due to the installation height. Instead, he recommended installing electric heating mats to supplement our radiator. The floor will also need insulation from the basement side. We plan to install tiles again. A room temperature of 18-19°C (64-66°F) is completely sufficient for us.
What about the (ongoing) costs?
Which option is more cost-effective?
Would it also be possible to mill out the screed and lay heating pipes so that the radiator could be removed?
I am not familiar with underfloor heating and have never had one before...

I would appreciate any advice.

Then why use underfloor heating? (Wort5 + 30 characters)

You could use the prefabricated mats for retrofitting. They have a thickness of only 8-10mm (0.3-0.4 inches). This might make a radiator unnecessary.

What do you mean by that? Because underfloor heating is more efficient and therefore warms the tiles.

An electric underfloor heating system is probably the most inefficient option you can install. You can practically watch the electric meter running.
But it’s true, the tiles do get warm. However, you don’t need an additional electric underfloor heating system to reach 18-19°C (64-66°F). That’s actually quite cold.

It is better to integrate infrared panels into the ceiling. It is more cost-effective, does not consume more energy, and heats all objects below. Infrared panels on the wall are also possible, but never opposite a window...
