Less serious posts should go in !casualuk@feddit.uk or !andfinally@feddit.uk
More serious politics should go in !uk_politics@feddit.uk.

Pick the most appropriate, and put it there.
Posts should be related to UK-centric news, and should be either a link to a reputable source, or a text post on this community.
Opinion pieces are also allowed, provided they are not misleading/misrepresented/drivel, and have proper sources.
If you think "reputable news source" needs some definition, by all means start a meta thread.
Posts should be manually submitted, not by bot. Link titles should not be editorialised.
Disappointing comments will generally be left to fester in ratio, outright horrible comments will be removed.
Message the mods if you feel something really should be removed, or if a user seems to have a pattern of awful comments.

Having lived in Australia and New Zealand and spent time in Chicago. British houses are horseshit.
Don't even need heating in standard UK temps if the building is insulated. Air to air heat pumps are amazing, induction is amazing, no issues with electric water heaters.
Living in fucking 1975. But everyone's ideal is trying to upgrade to a 1850 wood burning stove. Buy a fucking heat pump and some insulation.
Heat pumps are great when the house is designed for it. Average uk house with shitty insulation and radiators that are unable to heat the room unless the water is really hot - it’s not going to work well.
Not true. Heat pumps just need to be sized correctly
Link me to a heat pump that produces water for central heating at 70C or more. Typically, flow temperature is closer 40C, which won’t heat the average house unless you increase (possibly double) the size and/or number of radiators. Which is expensive and not always feasible. You can run heat pumps at higher flow temperatures, but that reduces their efficiency. Don’t get me wrong, i think they are great. But successfully retrofitting to old UK housing stock needs expertise that is in short supply.
Houses that can't be further insulated simply need a bigger pump and larger radiators to make it work. No need for 70 degree flow temps at all, though 50 is easily achievable. With the government grant Octopus are currently charging not much more than a gas install.
I’m not saying it can’t be done. But a larger heat pump and replacing all radiators drives up the cost, there is not always space for a bigger radiator, (and water tank), and while higher flow temperatures are possible, it tend to reduce efficiency. Sometimes it’s just not worth the investment, not helped by the big gap between gas and electricity prices in the UK
Your initial comment was that the average UK house isn't suitable for heat pumps. This is incorrect, in the vast majority of UK homes (including the poorly insulated) they can be heated sufficiently by a heat pump.
Don't spread misinformation. Some installers have fixed prices regardless of the number and size of radiators. There's even solutions out there where a hot water tank can be fitted into a standard kitchen cupboard.
You keep mentioning high temperature units which are less efficient, they are only needed in very niche installs or used by poorly trained installers.
