Hello,
after swapping rooms, I noticed that the underfloor heating in the room now used as the living room is not sufficiently powerful. It was installed as a "bedroom" but is now intended to be a living room.
I will probably need to consider an additional heating option. What possibilities are there?

I’m afraid that with heating systems (except for an electric fan heater), some invasive work is always required. So it’s acceptable if something needs to be chiseled open.

Well, it’s basically a calculation. You can get an infrared radiator today for 250 euros, then if you have an electrician spend two hours on site including travel time, you’re at around 400 euros. An additional radiator with all the extras for the heat pump radiator will cost you no less than 2,000 euros.

Another option to consider: a split air conditioning system, used for supplemental heating in winter as a heat pump and for cooling in summer. These are also available in the design of a standalone unit with a discreet appearance.

Would a split air conditioner be used as a supplementary system or as the main heating source?

Additionally, experience guides the use of the different heating systems in the house. A climate-split system responds faster, while underfloor heating is slower. Just a thought—there are good videos on YouTube about hybrid heating systems.

These are also available in the appearance of a freestanding unit, making them less noticeable.

We have it set up in a similar way.
Depending on the situation, the air conditioning unit is turned on briefly in winter to warm up the space. In summer, the benefits of the air conditioning system have become indispensable for us.
