We have a brick-faced house (built in 1993) that we want/need to renovate. Initially, it was only supposed to be a new floor covering. Now we are looking at new windows, a new heating system (oil condensing boiler), new interior doors, and underfloor heating for hot water.
We want to convert windows into patio doors. Therefore, the radiators need to be removed. We don’t have enough wall space for wall heating, and we do not want ceiling heating.
The house has no basement. On the concrete slab, there is 5 cm (2 inches) of polystyrene insulation and 5 cm (2 inches) of screed. The entire ground floor (100 m² (1,076 sq ft)) is to be fitted with underfloor heating.
There are now two options:
1. A surface build-up solution.
Pipe support panel, pipes, and leveling screed on top (e.g., Knauf 425). According to the manufacturer, the build-up height without final floor covering is 20 mm (0.8 inches).
The surface build-up solution costs about 3,300 € plus leveling screed (approximately 30 €/m²).
2. The screed including insulation is completely removed. The domestic water pipes probably need to be replaced as well. For the complete solution, the price for new screed (removal of old screed, new insulation, and new screed) is about 6,800 €. The price for the underfloor heating and possibly new domestic water pipes is not known yet.
The surface build-up solution has the disadvantage that interior doors, patio doors, and the front door need to be adjusted.
With the complete solution, all furniture must be removed from the ground floor at the same time. Bathrooms and guest toilets must also be emptied. We do not have a bathroom available on the upper floor.
Whether we can stay in the house during the work is still uncertain.
Until now, everyone has advised us against the complete solution.
We also have an energy consultant. However, this does not make the decision easier.
If possible, we do not want to move out since we have animals in an outdoor enclosure. Also, if we can save money, we won’t be unhappy about that.
Maybe someone has advice or ideas.
I would be grateful for any tips.

Thank you for your reply.
We have carefully considered the decision regarding an oil condensing boiler.
The renovation topic has been on our minds for over a year now.
Basically, we prefer renewable energy sources,
but solar panels, for example, are not feasible for us due to the orientation of the house.
So, we don’t need to think much more about that.
Our energy consultant is a certified engineer.
Basically, both options (retrofit and complete replacement) are feasible for us.
I’m hoping to get input here from people who have already implemented one of these solutions and might be able to share tips, or perhaps further information on alternatives or similar options.
Best regards.
