in merely cool weather a heat pump can achieve a 4:1 uplift which puts
it at about 5p/KWh.

That's comparable in my case with oil at 50p/liter.


I keep hearing folk extolling the virtues of heat-pumps but I was under the
impression that gas was cheaper for equivalent output.

Well compare the figures above. I have no idea what gas costs.

And remember in the depths of winter even a 5KW heat pump at 2:1 uplift
may not be enough...
