Iceland's Hellisheidi (pronounced heltliss-haydee, not Hell is Heidi!) geothermal power station sends 130 MW of heat along a 25 Km hot water pipe to Reykjavik, where virtually all buildings are district heated from it. It also produces 300MW of electricity.
Doesn't this call the bluff of those who say that it is impossible to use our relatively large gas fuelled - and nuclear - power stations to provide CHP heat on a multi-hundred Megawatt or even Gigawatt scale to British cities?
Heat is now a big issue for carbon reduction - we can't go on burning gas in small boilers just to heat our draughty houses for ever.
Is it time for a pilot CHP scheme?
Perhaps we could heat Bristol from Hinkley C?
