A couple of figures that seem sorely missing from this article: what's the COP (coefficient of performance) of these heat pumps? And they talk of some temperature rise, but what's the temperature drop in the water they're going to dump back into the sea or into the river? Without these it's impossible to understand the environmental viability of these projects when compared to fossil fuels. So are these a significant improvement or just PR pieces for the suppliers? Give us the figures!
