Underfloor heating Installation cost

kduoblys

Hi I thinking to get underfloor heating system in my 10 year old semidetached house which would be 54m2 connected in gas boiler
I wondering how much roughly will cost me ?
Do I need rip off subfloors hard-core? if yes how much is that ?
Thank you.

Can you explain why you want ufh?

I think is more efficient and it's nice to walk on the warm floors...

More efficient.. Not likely.

Nice under foot.. Put on slippers

To do this 'efficiently' you'll be:

moving out,
Removing:
floors, cango concrete, insulation radon, radiators, pipework, skirting, storing doors,

New:
thicker insulation, radon membrane, ufh pipes, concrete/screed, skirting, rehang doors, clean and paint everything, floors throughout

New heat pump? You'll hardly run ufh with the gas boiler? External Wall insulation to reduce thermal bridges at floor perimeter?

I'll let others cost this. I would caution that it will more than you expect

Thx BryanF, that is a big list to do, agree.
But I am looking a prices anyway how much would cost me all of this?
probable I will change gas boiler to air to water, I don't really know much my self about it I need that someone would help/guide/recommend or advise what is better.

can you describe in some detail the current construction of the house:
walls
floors
roof
..
then detail current insulation in walls, floors, attic.
then detail current heating system for both rooms and hot water.
current ventilation in all rooms.
..
what is the current and planned occupancy of the house and how long do you expect to stay there?
..
This project as you describe it could cost you euro 54,000, plus: so my thinking is that if you have that sort of mula to shell out, it would be much better spent on upgrading the existing fabric of the building and not starting by digging out what I expect are perfectly good, ten year old floors.

Calahonda52 I just after purchasing this family house I think for long term invest. just talking about ground floor.
Interior plasterboards needs to be replaced,
Need to rip off floors till slab and put in new tiles and new floors. Building Slab is total fine, I think if I put on the slab heating floors it will come up 200mm that's a bit too much in my opinion.
Roof is fine.
heating system what I know is Gas boiler which I thing may to replace.

I asked for the information earlier so as it would help inform the discussion.
You obviously have a predetermined course of action planned here so am stepping out.

Unless you have unlimited budget I'd say retro fitting ufh in a semi-d is well down the list of things you could invest in the home.

Assuming it had original Doors Windows insulation, investments in these are going to make it feel more comfortable than the feel of ufh.

I slowly changing my mind already... I think I will stay away from ufh floors... they cost fortune.... You right, It makes more sense Get good windows and doors, insulation.
Thank You for advise.

Was involved in UFH. Did not supply many retro fits. You would get away 100mm high density insulation and about 50mm screed. that's the absolute min.
No problem heating UFH with gas. Just uses a mixer system to lower the heat.

As you are thinking of doing other things instead. Wouldn't disagree with that.
If it is only 10 years old, the spec should be fairly high.
