If you really want to be warm, forget about underfloor heating.
Whenever I look at a these systems they invariably are used in
conjunction with other heaters and the owners just wont admit that they
are useless because they spent so much money putting them in.

Certainly, the numbers suggest that unless the room is well insulated, the
total heat output will be insufficient. However, they have significant
advantages over other methods. In particular, they are very useful in
rooms
with tiled floors, such as bathrooms and kitchens, as they enable you to
use
the room without having to find shoes or slippers.

A new floor with lots of foam insulation under, and to the sides up to
screed level, forming a tray, will not be cold. The tiles will eventually
heat up with the heating system and not lose heat to the ground beneath.

Having UFH and a Myson convestor is expensive madness. A kitchen needs heat
instantly and to be able to stop heat instantly. A kitchen is the last
place UFH should be considered.
