underfloor heating, electric vs gas...

[alphonso]

Hello,

I'm having the floor re-laid in my kitchen with underfloor heating.
It's about 30sq m.

The proj mananger is recommending electric, but has no experience of gas heated water pipes. Surely the normal gas heating is far more efficient and cheaper to run?

Does anyone have any definitive idea, rather than an assumed opinion?

[alphonso]

yes, that's right, she reckons £700 for the electric system. I do have a boiler and central heating.

The thought of putting an electric current through 200m of heating cabling sounds horrendously inefficent and expensive, but I really have no idea.
