UFH

With electric UFCH, it is worth remembering that the mat types must not be covered with rugs or furniture which could stop the heat escaping. The covered area could overheat and damage the element. Because of this risk, particularly in living areas, such as lounges and conservatories, I recommend that the customer has a self regulating cable type of heating.

The cable that I use self regulates to 29deg therefore cannot create hotspots.
 
For the people who were asking about running cost.

I spoke to someone at Devi and they have ionformed me that for 100-150 wattage you are looking at about 0.6p to 0.7p per square metre per hour.
 
I've lost the maths! My bathroom floor is a small footprint of 2 x square meters. So If I have it installed and run it for three hours a day from 6am to 9am then the maths is..

2x 0.75p for the square meters (total 1.5p)
3hours x 1.5p = 4.5p per day
4.5p = 31.5p per week - £1.26 per month and £15 per year

Is that right ? (or £15 + 40% energy rise this winter = £21 per year)
