And you have to "sell" the idea that it will be more expensive to
install, and maybe to run, and (according to the article) will take
longer to heat up a room - presumably because it is lower power.
That's a hell of an advertising and PR campaign that you are going to
need :-)

Something like..

"It's not lower powered, it's more efficient."

That's almost as bad as the low-powered vacuum cleaners which don't
produce enough suction so you have to keep going over the same bit of
carpet, or lower-powered kettles which take longer to heat the water...
but the legislators can't see further than "it uses less power".

The kettle thing is particularly short-sighted because it takes a fixed
amount of energy to heat a fixed amount of water: it is irrelevant
whether it's 3 kW for 2 minutes or 1.5 kW for 4 minutes - the amount of
energy used is the same.

but you might get more radiation losses with the longer time?

Not enough to matter with only double the quite short time.

Still no point in half power kettles tho.
