ᐅ Replacing Radiant Floor Heating with a Different Underfloor Heating System – Is It Worthwhile?

Hello everyone,

We will be moving into our new home on 01.02.19. As part of the renovation/refurbishment, we plan to remove and replace all the flooring.
Since the floor will be taken out, I am now wondering if it makes sense to mill in underfloor heating into the screed. The existing heating system, like the house itself, dates back to 1989. The area to be renovated is 100m² (1,076 sq ft).

(Laying the heating system on top of the existing floor is not desired because it would lower the kitchen floor even more, and I assume it would cause problems with the windows and the front door.)

Does this change actually make sense, given that the underfloor heating is already quite old?

What about the kitchen? Do I need to remove the kitchen units, or is it enough to lay the heating pipes along the cabinets?

What costs should I expect? We have a current quote of about 3,200 € for milling and connection. Are there any additional costs I should plan for?

Looking forward to some advice and opinions.

Thanks in advance!!

Thank you very much for the great answer!!

The boiler is relatively new, built in 2016, so I assume it is already optimized.

Do I understand correctly that the existing pipes could possibly also be used as underfloor heating? That would be even better!

Since the house has been retrofitted with cavity insulation, it might be possible to achieve sufficient heating capacity.

What does "5-10k" mean, and what is a building services engineer (TGA planner)?

TGA stands for Technical Building Equipment. The planner can calculate how much heating output you have and how much you need.

If the return flow pipe is installed in the floor, is it even possible to mill into the screed?

Okay, thanks.

I’m not sure if that’s possible, but according to the quotes so far, no one has raised any concerns. However, no one has suggested converting the heating to underfloor heating either. The conversion would only benefit me, not the respective company.
