Those with underfloor heating - please help!

[hex]

We're thinking of underfloor heating in our new kitchen extension (yet to be built)and we're wondering:

a) does it heat up the room or just the floor or do you need radiators as well?

b) where did you buy your underfloor heating from - and is it like an electric matting that goes down? - are there diffrent types and which is the best?

c)and crucially (for us) what sort of flooring do you have on top of it...tiles? (slate/ceramic??) real wood...laminate? - in other words, what's the best kitchen flooring to go on top of it? which retaims heat the most?
cheers

Hiya hex.

Well dp has gone and bought some underfloor heating matting.

It was halfp price in homebase as it was end of line, and dp (who can't resist a bargin) has bought it ( makes devi, a 2m2 and a 3m2 - we need two as our kitchen's on 2 levels).

So we have the 2 mats and 1 thermostat.

But as yet it's not fitted so I'll let you know how it goes.

(Although if the state of the boxes it came in is anything to go by, I wouldn't hold my breath )
