ᐅ Alternative to masonry heaters, substitute for masonry heaters

Hello dear forum members,

we are currently considering purchasing an existing property, but it has a significant drawback: the heating is provided by electric storage heaters.
The energy certificate indicates an energy efficiency rating of B for a living area of 160 m² (1722 sq ft) with a consumption of 66.2 kWh/(m²·a). The building was constructed in 1980, and the roof was insulated in 2009. The storage heaters date from 2005.

We are wondering what the most practical way would be to replace the storage heaters. So far, infrared heating has been suggested as an alternative, but does it really offer better efficiency?
What alternatives exist that don’t require, for example, completely replacing the floors including the screed?
Or if there are no alternatives, what rough costs should we expect for a 160 m² (1722 sq ft) property over two floors?

Thank you in advance, and I am happy to answer any questions.

Ceiling heating in an uninsulated existing house is very uncomfortable: warm head, cold feet.
Also, the consumption of 66.2 kWh/m²a is probably based on actual usage and heating was not applied...
Installing new flooring heating or radiators is practically the only alternative, possibly also wall heating.

Yes, the energy certificate is based on consumption. There is a wood-burning stove in the living room, which may have been used extensively.
Does wall heating have disadvantages compared to underfloor heating?

I have been renting for about 2 years with storage heaters. These things consume a huge amount of electricity. You can forget about infrared heating. We are lucky to have a wood stove in the living room. I will be really glad once we are finished building our house. If you want to buy the property, I can only recommend switching the heating system.

This cannot be answered generally and depends on the specific conditions.
For example:
1) If you want a beautiful plank floor, solid wood, thick boards, underfloor heating is less ideal and wall heating is more efficient.
2) If the entire floor is tiled and you have wall heating, the floor will always feel uncomfortably cold, so you should wear slippers.
3) If the walls are very complex in shape, possibly paneled at the end, the effort to install wall heating is very high.
4) In older buildings with low ceiling heights, you don’t lose height with wall heating.
5) And so on...

Okay, you are referring to the local conditions. But apart from that, strictly technically speaking, is this an equivalent system?
