Aware that #heatpumps are currently costly and difficult to fit, but this article is neither objective, nor factual. Error 1: "When it comes to winter warming, you can't beat gas central heating.". Fact: Low temp heating with a heat pump is more comfortable than with a gas boiler
Error 2 "some of the new-style kit can't heat the UK's cold, draughty houses." Ignoring that some of our old-style kit can't heat our draughty houses and we have the worst #fuelpoverty in Europe. Fact #heatpumps can heat draughty houses, but why would you want to? Fix the homes.
Error 3: "Hydrogen lobbyists say it can travel through existing pipes - at least until it reaches the home." Key words there (apart from the 2nd) are the last 7. Presents #heatpumps as disruptive, which the installation can be, but then glosses over replacing internal gas pipes.

(1/4) There has been a lot of chat this week about the cost of #retrofit #heatpump installs. Here's an installer's view on the three types of costs that drive it - 1. Costs that won't change 2. Costs that intervention could change 3. Costs that will change as the market grows.
(2/4) The first time you retrofit a #heatpump it will always be more expensive than a new gas boiler. You have to put in a new hot water tank, run pipework outside, build a base for the heat pump, ensure radiators and pipework are adequate. These costs vary from house to house.
(3/4) There are also costs that government action could reduce: streamline the process to connect to the electricity grid; invest in training installers; mandate low temp boiler installs; make the planning conditions more sensible (1m from property boundary, why 😡?)
