Underfloor heating question

[The Natural Philosopher]

low enough to get about 15 degrees rise easily, but I struggle at 20 degrees rise.

[Grimly Curmudgeon]

It's lovely to have, but if the house is well insulated it's an unnecessary expense if you're tight on budget.

[The Natural Philosopher]

UFH is good because it gives you warm feet and it means you tend to actually run the house at lower temps. Its also good because it can use low grade heat from heatpumps. Its also good because the radiatior IS the floor and that means walls look better.

But none of these things is an overriding concern in a retrofit, where the expense of doing it PROPERLY will outweigh the advantages.

Neither is it advantageous in a house with low thermal inertia that is often unoccupied: screed floors have massive time constants, and that means you end up having to heat the place most of the time whether in or out. With good insulation that's no big deal, but not on an older house.

That would be the Churchill Flooring you're the Tile Manager of, would it?
