If it's just for the kitchen, then UFH is not a bad idea. If you are comfortable doing this, know the specs and equipment needed for it, then go for it !! It can be straightforward, if you know what you're doing

hi it is just the kitchen ,and i have flow and return pipes in perfect place ,is it a special pipe or is standard plastic 15mm pipe ok to use and i dont suppose you now how many metres of pipe needed for the job

depends on how much you wanna pay really?if your system can cope with pumping the underfloor and not starve the rest of your system, underfloor can be pricey! i personally would stick a rad in there but its personal choice

You can get 'extension' UFH kits that will service just one room, they come with what you need to undertake the job

Tha just one particular make, there are others too

Underfloor heating is the better solution in every respect (until it leaks!), but as you can see it's more expensive. Do make sure it is properly fitted to work with the rest of your system.

These are good for a small room system <15M2 & your existing circulation pump should handle the extra load;

Just buy a coil of 100M x 15mm JG pipe, fix it to your insulation at 150-200mm centres, connect to the above valve & no pipes below the kitchen units....................Job done!!!

Over £200!!! What a f..king rip off!!!

If you ever lived in a home that has UFH you'd never want to see a radiator again, it would be my first choice every time.

The link was an example for the OP, Delta. As for your opinion that UFH is the mutts nuts, I personally think the heat it emits, especially if you are sitting down for a long period, is oppressive. But thats just my opinion

Oppressive eh, well!!

Seriously, the chances are the system was designed wrong or had limited controls. Radiant heat is different granted, for example 17 feels like 21*C and there's very little air movement in a room with UFH. Convection heat(radiators) heats the ceiling before you & there's loads of air currents going on.
