I'm thinking of installing electric underfloor heating in a soon to be built conservatory which will have laminate flooring. Now I know how to calculate running costs based on theoretical usage i.e. the internal size is 12m2 and the mat will be 130watt/m2. So @ 10p per kw/h it'll be £3.77/day however I'm presuming/hoping that it wont be drawing this much power constantly as it'll be set mostly to lowish background heat throughout the daytime whilst we're out at work.
Anyone any experience of rough running costs on a similar system based on actual bills?
