We are doing major changes to our kitchen to make it open plan to a

floors we wanted to look at underflooor heating. We will have a gas

boiler system.
Any personal experience out there? Is it costly to run?


Cheaper than rads as a lot less heat loss due to convection - and no
convection draughts.

Freedom to put furniture anywhere, no hot spots - even warmth.

Very much a DIY install - Nu-Heat for example make an add-on pack for
adding
underfloor heating to a conservatory, by tapping off existing rad circuit.

Control is different - not on/off, but set back temp, i.e. you set it to
go
to for example 10 deg lower when unoccupied rather than off - that way it
only has to bring up from a background temp rather than from cold.
This helps negate the slow response time.

Anybody who has had UFH .... will never go back to rads.

That's if its designed well, installed so no cold spots on the floor and
well controlled. If not then they can be very uncomfortable and nighmare to
live with. Having weather compensation helps to alleviate the warm and cold
periods, due to the slow response, when the weather suddenly changes.
