Carbon emissions of electric heating v gas

Its good to compare, but at the end of the day, renewables are always maxed out by policy. On occasion we have a small amount of excess/lost renewables, but unless your demand happens to coincide with this additional new demand must come 100% from gas produced electricity (maybe other sources but mainly gas).

Right now we are seeing a large increase in sales in electrified transport (battery cars/vans etc), driven by new/cheaper tech and global gov't regulation proposals to ban petrol/diesel engines. Even with 100% gas powered electricity these mean less pollution and CO2 than their fossil counterparts, they also provide storage and grid stability as well as absorbing all excess renewables with flexible demand and even feeding power back.

Heat pump are very marginal with 100% gas electricity, real COP figures need verified in 'normal' installations rather than test conditions. A non ideal location, combined with the wrong wind and cold temps could easily lead to much worse COP than rated. Ideally equipment should measure this in real time.

Battery vehicles will not be at critical volume for another few years, but its does not make sense for several new sources of demand to claim lost or new renewables as evidence that the grid can support a CO2 reduction from electrification from a new source. Transport has been a problem areas of increasing emissions while other sectors have been reducing, it stands to benefit us the most.
