Npw here's an interesting concept - natural gas fuelled domestic ceramic fuel cell, 2kW output. Ready for production release from the looks of it.

Anyone heard anything?

Most of the time you will be using less than 1000 watts so you get around 300 watts of heating. Underfloor it would be enough to take the chill off assuming your home is reasonably insulated. If the percent value reduces with reduced consumption as a portion of energy then the numbers will vary. Its worth it in cold climates. Underfloor heating can work effectively on half the energy or less so if you are watching TV and have a computer on there will be a gain in warmth and comfort in the house. |
