I have responsed to the consultation request. Generally in dense urban areas wind generation isn't going to work well because of messed-up turbulent air and noise and flicker and ice-throw issues. But there's plenty of England for which this might work. I also pointed out that single-axis HAWTs should not be assumed to be the only game in town. My tiny MotorWind setup worked reasonably in my very poor location, and other novel (probably not VAWT) designs might work. I have suggested a limit on total swept area or output power or to ~10% of expected output power for a full wind farm in the same location, ie this should not be permitting a wind-farm on the sly, but should allow low intensity microgen energy extraction to support farmers or factories or community projects...

Most urban wind is very poor, and mounting a turbine on a home makes for a lot of vibration noise. If you are in rural area with a bit of space, especially coastal, small wind can make sense.

Is there no rear space beyond the conservatory? Do you have a flat roof, eg on a porch, that might host the external unit? https://www.installeronline.co.uk/green-energy/installing-ashps-on-roofs-and-walls-what-installers-need-to-know/ There are variants without external units, eg: https://www.etherma.com/en/blog/heat-pump-without-outdoor-unit

That is not safe, as clearly no or bad mechanical strain relief and exposed wiring that isn't meant to be seen or accessible. Live mains voltage might only be a screwdriver or paperclip jab away. This may be indicative of other sloppiness and poor H&S and compliance.

Our use of the dehumidifier is mitigation for a place where ventilation is inadequate. But given the short likely remaining life of this building, though I'd like to fix it with (say) more single-room MHRV, it doesn't seem worth the candle.

Our portable heat-pump dehumidifier draws ~180W: https://www.earth.org.uk/measuring-appliance-consumption.html#dehumidifier-425/0777

Try your local Freegle or FreeCycle?

Because our gas boiler kept expensively failing so replacing it is expected to be a financial win, and I am definitely a supporter of electrifying everything, and heat pumps are the main focus of my PhD research! Part of my reasoning is here: https://www.earth.org.uk/note-on-combi-replacement-dilemma.html

That is a new and very introspective version of range anxiety - I salute you!

One rad change here retrofitting from gas to ASHP. Actually I should probably have bumped it up in size a bit further. But no other changes. For a new house I might well choose UFH at least in part, but that doesn't seem necessary.

A couple of visits to -5C here in sunnyish London have passed without incident for our ASHP. Flow temp got up to 47C... (I have 50C@-7C for one end of the WC 'curve'.)

If the embedded carbon/energy is a concern (and generally I don't suspect that it is for machines of this level of complexity), couldn't you gift it to a local gas spares place or GasSafe person for parts? When my combi was stripped out I did just that with the rather expensive heat exchanger that I'd put in just a year before, and the man was very happy. The sooner people switch to ASHPs and stop directly adding several tonnes per year of CO2 to the atmosphere via the flue, the better.

On my system am I pushing the weather comp curve down a few degrees (ie applying a setback to flow temperature, not room temperature) during peak: https://www.earth.org.uk/heat-pump-16WW-control.html#current I am actually on a flat tariff, but I did think about how I might make this work saving cash and carbon with Cosy: https://www.earth.org.uk/heat-pump-16WW-control.html#Cosy For our old gas combi I did indeed have the space heating entirely off for 4pm to 7pm.

Would a forced convector (ie with a fan) do a better job of distributing the heat?

Porous Tile Stain Dementia?

It optimises for occupancy, reactively and predictively, yes. Most people want lower temperatures while sleeping, but maybe not an icy room as they go to bed. That's effectively what Radbot aims for.

I agree that that fault mode is plausible.

There are solutions such as ... ahem ... Radbot, which don't need any particular central hub/stat and help manage the temperatures in each room automagically.

It may be @Pocster's WC seen from above with him on it...

By ensuring the that the system tells them just what they need to know to get there, and helps them along, assuming it's possible. ("Heat the house for zero cost with all the windows open when it's freezing outside" doesn't have a good solution!) And not expecting the end user to have a physics degree: "folk physics" seems to be bad in general.
