Underfloor Heating is the only real option for Geothermal.
Why?
Unlike other forms of wet CH, which use radiators, UFH when correctly installed, loses little heat to the substrate, but radiates heat gently upwards via the floor.
Once the thermal mass of the floor has reached temperature, the floor heat creates a classic thermo-cycle, but at the bottom of the room.
Most radiators also create a thermo-cycle, but at the top of the room. (Try standing on steps with your head just beneath the ceiling in a room with a wood burner working at maximum and breathing deeply!).
People don't need heat just under the ceiling: they want it at waist height. UFH allows significantly less heat input to reach a cosy environment thus it's cheaper to run.
UFH also spreads the heat radiation uniformly across the whole floor: not just in localised "Hot Spots" around radiators.
Unfortunately, installing UFH in an established property as a Retro-Fit is not normally viable, due to the dislocation, mess and cost: it ought to be the first choice for all new builds and barn conversions (e.g.).
UFH is invariably used for environmentally friendly builds.
It is critical for the quality of ALL underfloor materials and workmanship to be of premier quality, since after the top floor screed is poured, it's too late for snagging!
Employing the latest synthetic materials, well designed and installed UFH should demonstrate a life expectancy of 50 years ++
I think that's all: but slept in unusually today and still slightly dozy!
I have often wondered about this myself, the main drawback seems to be that you need to switch it on several days before you need the heat in order for the system to heat up the floors.
Conversely of course, if you've got the place all warmed up and the weather suddenly becomes hot how do you turn it off ?
I can't help but feel, that unless you live somewhere that is permanently cold it may well be a waste of money.
Paul, I think it's probably a bug, but you could try switching from the design view to the HTML one (buttons at bottom left hand side of the text input window) to see if the formatting code is carried through to there, and then manually delete it?
Not perfect, but a workaround.
