Another incredibly frustrating thing for me is the amount of regular people adamantly against any green energy being built near them. Which basically means no where in the country.
Would these people prefer a coal plant??

That's the right wing media for you. I don't have them blocked in my newsfeed so I can see what they are up to and it is a completely different world - pretty much anything green gets hammered.
Bless you. I do have them blocked. I don’t need the aggravation in my life.
We need to start calling it blue, not green.
My reply to them is: “Would you prefer to live next to a nuclear plant, or some turbines/solar fields?”
@PixelTron@lemm.ee
@rimu@piefed.social @breadsmasher@lemmy.world I've lived next to both, and it makes no difference. Both are good neighbors. I won't live near coal power plants or oil refineries though.
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.
Ah, but then you'll have to put up will all the folks whining about new builds, and that a waste outlet pipe wasn't connected properly, Vs a 60-70s that's still standing so must be much better, as long as we ignore the black mold in the cavity that is slowly killing us.
And also the 40 odd years of “DIY” bodge jobs holding it all together
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.
I don't see how and air to air heat pump wouldn't work.
Insulation needs to be solved yes. But if you heating your house with gas verse electricity if the output is the same then the result is the same.
Something to do with physics. It’s not just about the heat output from a gas boiler vs heat pump. It’s the output from the radiator to the room that matters. For the same output, a gas boiler heats the water to a higher temperature than a heat pump. Which means a radiator gives out more heat to the room. As an extreme example, if it is freezing outside and the heat pump produces a lot of water at 15c, it may have a high thermal output but still wont keep your room warm. If it produces water at 30c, the radiator will transfer some heat to the room, but unless the radiator is very big or the room is well insulated, probably not enough.
That's not how air to air heat pumps work.
My parents 1741 house with new double glazing is like that - cool in summer, hot in winter without even needing the heating
I'm amazed that we collectively forgot how to build houses but I guess 2ft thick walls make a dent in the size of the living space and you've got to build a box with paper thin walls and no garden to optimise that
Thanks, conservatives!
