Why are ASHP installs so expensive?
Posted by: @springswoodFrankly I still don't understand why our electricity is so expensive. Still, that fact that other European countries don't have such a big difference between gas and electricity suggests it's down to policy and not engineering constraints.
It is a politically motivated myth that our electricity prices are vastly more expensive than the EU. We are certainly amongst the more expensive (#6 out of 40), but not dissimilar to other large countries in the west of the continent; Germany, Ireland and Austria are all more expensive. Even France, with its abundant nuclear power, is only 20% less expensive.
Our gas prices on the other hand are somewhat cheaper than our large neighbours, for example we are nearly 40% cheaper than France.
Taken together that makes a big difference to gas/electricity ratio.
Here is a good representation of both, figures from Eurostat which is the EU statistics body. There are some insights here as to the differences.
4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
