No past experience. However, as I am in a semi-hard water area I would put in a water-softening setup before I went for one. Around here, rads become more difficult in a couple of decades.

Yes - I will have a look in the next day or two.

It is sometimes more effective doing a Google search with +buildhub or site:buildhub.org.uk in the search box.

Picking up DD's point, I interpret Prior Approval for the oversized extensions (though TBH I though it was a time limited thing and the law had expired) as "Extra Consultation in Advance to make the process simpler further on if you need the extra size, to avoid a full planning all in those circs and use PD". I think the history is that it came in for oversized PD extensions to reduce the need for full PP, to help smooth the way out of the crisis in 2013. Is this a helpful summary over at the DB wiki? https://www.designingbuildings.co.uk/wiki/Prior_approval_for_permitted_development

You also have the option of a thermostatic kettle, at the cost of about £70, or 3-4% of a Quooker. I have had one of these for about 8 years, and it is great at doing water for coffee at 90C. It is a Bosch TWK8633GB Styline. eg Argos https://www.argos.co.uk/product/4239712 I'm going th eother way and thinking about a boiling water tap and water softener as part of a kitchen refresh. (Checking the latest, I see you are already in this camp!) F

My theory is that your Smart Meter is telepathic. Or as has been suggested, guessing.

@Fly100 Great to see you being as thorough as you can 🙂. I did huge thread earlier, but it needed to be made digestible - so I'll need to revisit. F

I don't know - this, including how much you should pay for access, should be in the party wall act award. It needs to be one of your ducks in a row, otherwise what are you going to do if she says know. https://hsfnotes.com/realestatedevelopment/2016/09/01/1163/#:~:text=The Party Walls Act creates,site and the neighbouring land. One for your skill and judgement 😉.

Have you dealt with the issue of any required access to her land you need to build your extension?

I'm trying to get to grips with this and other questions for my own house. As I read it, Tesla Tariff has a cap on usage at 9500 kWh from the grid per annum in day hours, at which point they make you switch. Does this affect you? If your daytime consumption (from 07:00-19:30) grows beyond 9,500 kWh per year, per-Powerwall-installed, you will be prompted to choose an alternate tariff that better suits your usage. Please note, if you own electric vehicle(s), scheduling your vehicle charging to occur outside of the daytime hours (I.e. charging any time between 19:31 and 06:59) will transfer a significant amount of your household consumption to off-peak hours. Whilst this reduces your daytime usage as a Tesla Energy Plan customer, this practice is also helpful for reducing the peak demand on the national grid, which further helps reduce national carbon emissions. https://octopus.energy/tesla/tariff/#/calculator Have you run it through the Tesla/Octopus calculator? A second issue is whether the 11p/11p tariff can be switched by Octopus and at what notice? (I'm on a FIT at about 14p per kWh for exports, so would not consider something dependent on a supplier's goodwill.) I think the current capacity of a Powerwall 2 is 13.5 kWh, and you install 2. https://www.jojusolar.co.uk/batteries-smart-grids/tesla-powerwall/#:~:text=A Tesla Powerwall 2 has,appliances are running at once. Having the option of charging the Powerwall to feed your ASHP in the day would give you a Plan B if you hit the daily limit on the tariff. To me a case for an ASHP dependent purely on a particular tariff sounds a shaky foundation - you need to know it will be worthwhile if that tariff eg doubles in price at some point soon.

There are options. Traditional hotlinking works iirc. It is under the "Other Media" option in the editor for either a forum post or a blog post. All you need is the unique address of the pic, and that the other end allow hotlinking. If you just copy and paste the image in via the clipboard, I think that creates a hotlink. IMO it is better to upload, however, as that can't be broken by a third party. Just make sure it is not many, many megabytes. ATB Ferdinand

Rainfuel? Does someone have a link? Thanks

You need to check what building regs you are subject to. If it is part of the dwelling, then you will need to insulate the wall to outside to the appropriate standard, as there are requirements to improve when you work on a thermal element of the building. Your local council are the people to ask. F

I think we will soon be seeing how quickly that can happen in Germany 🙂 . Though I am told there is capacity to use the European gas grid to mitigate in the meantime. F

If you are choosing to indulge in unnecessary personalised insults, I'm not interested. Don't bother replying to me; you are now on ignore.

If you have a sprinkler system I think you need a separate 32mm supply. Unless you have infrastructure such as a water storage tank.

ie Don't live in a dip in Bristol.

Nothing. It's a standard approach. You just need to make sure that it can take whatever you are going to have parked or driving on it. Eight wheelers? Removal vans? Hiabs from Wickes? Your rich uncle in his fatmobile? Two tonnes of bricks for the new garage just being delivered?

They all have power cuts and can#'t log on ?

That was one reason explained to me as a difficulty. The grid companies in a power outage will not want any risk of electric shocks for their repair staff, so will have insisted on failsafe technology.

I have a standby generator for my heating. It is a Super Ser.

Where would you keep them cold if not already in the freezer ?. Adding warm blocks after a power cut would thaw it out more quickly in my physics ! Mine live at the top and only get taken out for a picnic or if eg I'm going shopping elsewhere and need to keep eg coastally purchased fish cold for an extended period.

Can one not open the passive cat flap?

The "solar pv power in a power cut" is one that I have been reflecting on. Need to think about what the requirements are - do the rectifiers need a power supply themselves? The other mini thing I have in place is a couple of chunky phase change cooling blocks n the freezer which will keep it cooler for longer. These were supplied. No idea how they are specced, but total mass is 2.5kg.

Can you justify these numbers with a source before I rework, please? Happy to do so, however. Accept that. 24.4 GW current wind nameplate power capacity. This actually seems to be 17.6 GW, ie 25% higher than your number - though estimates such as we are doing need mean averages and totals, not peaks. On May 4 2021. https://www.theguardian.com/environment/2021/may/21/may-gales-help-britain-set-record-for-wind-power-generation I make that more like 8.6 GW, which is 50+% higher than your number. Based on wind energy generated of 75,369 GWh (2020 Govt Environmental Accounts), divide by (24*365), gives a mean average power output of 8.60 GW. Are you missing that Offshore wind has a far higher capacity factor than Onshore wind, and all the new fields are offshore? For offshore it is 46% - just under half, and for onshore it is 28%. For new offshore wind coming on stream it is higher, which is why I use 0.5 or 50% in my estimate. Seems so to me. 1 - In resilience terms, we get a new stable source of elec,which is overwhelmingly low carbon - 90%+ in No is hydro. Part of teh answer to "occasionally no wind, sometimes no sun"? 2 - In C02 terms that's clearly a benefit. National Grid have an animated presentation of live. Nat Grid say they save 3 million tonnes a year, even without full data from the new one. data: https://www.nationalgridcleanenergy.com/powerofnow/ 3 - In kWh, it is extra capacity if required - at a time when we are seeking to increase renewable supply availability. 4 - In £, it is a more open market, and aiui Norway Link gives us access to another pricing pool. Plus I see no reason why we can't end up being more of an exporter over say 8-15 years. 5 - Politically, diversity of supply has to be good, surely? I'll avoid politics, however, beyond noting Mr Macaron's efforts to use it as a political lever - electricity being France's 2nd or 3rd largest export to the UK. There's quite an interesting pipeline of interconnectors coming on stream (somewhat old list, and I'd expect some of these to fail): https://www.ofgem.gov.uk/energy-policy-and-regulation/policy-and-regulatory-programmes/interconnectors F
