Remove chimney breast when there is an existing wet underfloor heating

[Hayley1234567]

The house we bought needs an entire renovation. To save some money thinking about installing wet underfloor heating now and remove the chimney breast later on. Of course removing it will free up about a sq metre space where there is no underfloor heating. Will this compromise the heating or how to go about this?
I know to do everything at once would be the best option but we need to think about solutions how to split the renovation into sections/parts so we don't need to do everything at one go. (Based in the UK)

I have underfloor heating, although not wet. It does go right to the edge of all walls, so doubt that would make much difference. But you would need to add flooring there after, so that would be more difficult. Even if you get enough up front, it will fade and be scuffed, so the new part will look different. Parts of the wider floor might be damaged too. It feels like a false economy.

That’s not a great idea. You have to put your new floor over the pipes. How would this match new flooring where the chimney is coming out? It’s also a big job to take a chimney out so you’ll make a mess on the new floor. It’s not a saving. We have a fireplace and under floor wet heating. Fireplaces add character.

Unless you’re going to stay there for decades I wouldn’t take out the chimney. Future buyers might like it. Just because it’s there doesn’t mean you have to use it.

We are planing to live there forever. If we were to use it it would need yearly service so again, not cost effective as we would have the UFH anyway. So if we not use it it just takes up space which is very limited. Also it's not a usual fireplace, it is a triangle in the middle of the wall in an akward position.
Doing the floor later on wouldn't be a big deal. It's just laminate that locks into each other. It will be the last few lines of the floor so can just keep a box or two and remove, replace those. Did that before. Easy job with no extra cost.
