ᐅ Renovating an Old Building – Gas Heating with Radiators or Underfloor Heating?

Hello everyone,
Do you happen to know which option (underfloor heating or radiators) is more cost-effective when running on a gas heating system?
I’m not concerned about the initial purchase price, but rather the operating costs once it’s heating.
Key details:
- Single-family house with a 1.10 m (3 ft 7 in) high crawl space
- Approximately 90 m² (970 sq ft) of living space, which will be expanded by about 90 m² (970 sq ft) next year
- Built in 1960
- Gas heating system will be newly installed. Two companies have already visited and will provide quotes. (So far, they have quoted based on radiators. I haven’t asked about underfloor heating yet.)
We can set aside the aesthetic aspect for now.
I would appreciate any suggestions.
Best regards,
Farilo

How much consumption was there in the past years?
"Can go down a lot"... Okay... So oil condensing boilers adjust their output. I call this modulation.
That means if the system is properly set up overall and the boiler is correctly selected, it basically runs on a low setting instead of constantly switching on and off.
This is more efficient and gentler on the equipment.
This explanation is simplified, but it might help with understanding.
If there is no insulation on the top floor ceiling and possibly the sloped ceilings yet, this is the measure that absolutely makes the most sense. It can easily be done yourself at low cost. Definitely do this before winter!
With high-quality wooden windows in good condition, it is possible to upgrade them with new glazing. This is inexpensive and can potentially bring significant benefits.

Some of the windows have been replaced (PVC).
However, I am considering replacing all the windows. (Wooden windows with double glazing).
I am currently evaluating the advantages of wooden windows compared to PVC windows before making a decision.That doesn’t say much yet; whether PVC or how the glazing is done is less important. What really matters are the insulation values of the glass and the frame.
Except for the nicer appearance, wooden windows are generally inferior to those made of PVC (soundproofing can be slightly better with wood due to the material, but this also depends on quality).
PVC windows do not require regular painting.
If you want wood on the inside, wood-aluminum windows are an option; however, they are among the most expensive but also almost among the best. Even better are PVC-aluminum windows.
Thank you all for the explanations!
In mid-September, I will have the attic cleared out and cleaned, and then I plan to insulate the floor. I still need to decide which insulation material to use.
At the same time, I will also remove the current flooring. Depending on the condition beneath the existing covering, I will decide whether to install everything new with underfloor heating or keep it as is with radiators.
Does anyone have experience with the following heating system and can share their insights?:
Vaillant VSC 206/4-5 90
Thanks again for the information.

Heating system brand. Whether Junkers, Vaillant, Brötje, Viessmann, Buderus, the technology is proven. Brötje and all the others work well. Radiators also have the advantage of being less restrictive when it comes to floor coverings. For example, underfloor heating does not work well with loose laminate or wooden planks. Cork is also not ideal. Basically, underfloor heating requires firmly glued materials like vinyl or tiles. Karsten
