The cables I've looked at would consume 50 W per square foot. I'm only trying to raise the temperature from 2 C to 15 C. For this I believe 15 W to 20 W per square foot is sufficient.
My area is also small (see first post). For a larger surface, it would be more cost effective to use hot water pipes under the flats of plants, with water heated by a gas boiler.
