A heat pump installed in the UK today will emit 77-86% fewer carbon emissions than a gas boiler.

My analysis of heat pump lifecycle carbon savings made it into this letter to the
New Scientist.

@janrosenow It's probably worth writing something similar to a local outlet too. Where I am, the fossil fuels industry has people writing op-eds for local papers which try to compare efficiency using the unstated assumption that people will install resistance heating during electrification.
@janrosenow Would the carbon emission reduction be even lower for those who have solar and home battery?
@janrosenow sorry - greater not lower!
