We are having an extension built, and at the same time recasting our
double garage as a "family room". These two, together with the
existing kitchen, will be floored in Karndean (yeah, I know, very
expensive, but what can you do? I'm planning to buy it on-line
reduced and lay it myself.)

So, my question is underfloor heating - is it worth it, and if so, are
there any makes or systems that stand out? I'm not looking for
bargain basement, but I am looking for reasonable value for money.

Thanks

Ted.
