Get a Givenergy battery that goes outside? PV with battery just makes sense. Also make sense of fires and there actual causes, when linked to batteries.

Make the loops tighter and more loops, you can always run at a lower temp and pipe is cheap.

I've a borehole, you need treatment and sterilisation. It may not have done you any harm that you know of, but drinking water untreated, and unfiltered could be problematic in the long term heavy metals, high levels of sodium, phosphates etc. Get a sample tested, then put in the correct treatment for your supply. As a minimum..get a UV steriliser. Depth and location have no bearing on it really.

Just as an update - they accepted my PV solar invoice as additional and are paying it. Fairly straightforward process, which I'm pleased with.

It will via the battery. It's also limited by the battery output and storage, its not necessary a low power only output.

I know what you mean, Givenergy instructions give you the pros and cons. E.g. Doc also attached. EPS Configuration v2.pdf

Get a trade account with midsummer wholesale. Anyone can get that price.

Getting an MCS installed ASHP makes sense, BTW if you are rural you get 9k from the Scottish government. Solar panels, not so sure - its only 2500 back from the government. I paid (two weeks ago) 6700 Inc Vat, for a 7kWp array, givenergy 5kW gen 3 inverter, 9.5kWh battery, tigo optimisers for all panels (16-off) a solar iboost and buddy and all the rails and other stuff from midsummer wholesale. I can claim the VAT for it, so really £5583 for the system. Two days for the sparks (who are in the process of getting MCS approved). Say 6-700 quid. I'll have a fully installed system.

When I started 3 years ago, that didn't exist. Had I known I would have. I'd pdf'd all the invoices (440 of them) and printed them off but had to remove some, then realised at the last second it could be done online. Doh.

Where I had a proforma I included evidence that was paid, usually in the form of order acknowledgment or similar.

Ha Scottish...it was the architect who named it. Alternative would be boot room? It's basically the room where we take off shoes and hang jackets...

They look good the HEP20 ones...

By post yeah, but additional invoices will be done online. To be fair all my invoices were scans or digital receipts

Just to let everyone know I'd sent my reclaim on 26th Jan. They called me two weeks after that to check something, then letter received on Thursday there confirming payout. Mine was quite a large claim £35k, they had taken £1k off but I discussed with them and will send an explanation to resolve - they also might take my PV solar invoice which I'm about to buy on Monday (thought I wasn't doing this for 6 months hence didn't include it) as additional invoice. I'll update on that, I'll also attach my excel which I used which should be helpful for others.

No, it draws heat from the UFH. I don't know either, but if it was working it would keep heating the water between my heat pump setting (52 degrees) and the stat on the immersor then turn off, but it doesn't seem that has been happening.
