+1, as you’ll be on their insurance then also.

IIRC, no MCS certificate means zero export payments. You’d be better off with a smaller array and self-consuming all you generate if you go ‘DIY’. 8kWp may be pointless unless you can store all excess on site; eg big cylinder.

Dry capacitors instead of wet, and a 12 year warranty.

An example here https://www.smallsolar.co.uk/installed-systems/

Reading your posts @PeterW and @Onoff, I found myself nodding in agreement at every point.

@jamiehamy has a 500L Telford with 4x 3kW immersions IIRC.

What about making T1 a thermal store? Take the UFH off it too so heating buffer plus DHW pre-heat via the DHW coil?

8 showers all at the same time / staggered / 4 in the morning and 4 in the evening?? INPUT!!!!!

Look on the bright side, by that time we can get there on the bus for free!!

lol.. Don't be daft and put a small UVC in now. It would cost a hell of a lot more to retrofit another cylinder, and to jump up a few sizes now is cheap enough. Be a cheapskate all you want, but don't be stupid Give Trevor @ cylinders2go a shout and mention the forum. He'll look after you. Lots on here have bought from him.

That would make more sense tbh. Another great example of not being a penis and saving the wrong few quid in the wrong place. If the insurers ever found out that, he'd get the bill. Best we shut up.

Who’s paying 12p/kWh for export ?

90L here if you do go for the kettle option; https://www.guinnessworldrecords.com/world-records/67159-largest-kettle

Buy a dirt cheap DIY fit ASHP and fit a well insulated *500L UVC. Telford will spray extra insulation on for not much £££. Yes, electricity is very simple and convenient, and if that's your choice then it will work. Simple and quick. Larger storage means you can load-shift off E10 instead of E7, *so you can top up midday too if needed. Run the ASHP whenever you like, it's cheap enough to use not to worry about when, but anytime it's running on E10 you benefit even further . Introducing wood burning into the heating / DHW system is a big leap from simplicity so be very careful about how you introduce that into your equations ( as the installation costs will be big ). Difficult to say much more as you demonstrate a preference for options with a small capital expenditure. Log gasification attracts RHI, but you'd need room and at least 1000L of buffer tank, ideally more, plus a guaranteed / maintainable abundance of seasoned fuel stock.

Not really. If a registered installer goes to a job, they should see what’s ‘going to go wrong’ and make it safe. Same way when “we” cut a moulded plug off an appliance “we’re” supposed to mutilate that plug so it cannot be plugged in so the live cut off end cannot hurt someone who doesn’t know the danger of doing so. Regardless of the timeline, the last person there working on oil is responsible for at least identifying the possible dangers and capping off the old tank. If you went to a job where there was a shed that had been removed, and an SWA was sat on the grass still made off but just the breaker turned off, what would you do? If you ask for a little badge that says you’re fit, competent and qualified, you are then ordained to go above and beyond in all you do. In the instance of this oil spill, that due diligence fell to the wayside. On a project a year it’s ok ago, there was an oil tank with about 1800L of oil in it which was decommissioned to convert to a log gasification system. The scaffolders who put their scaffold yo for us to do the flue etc trampled all over the 10mm oil lines as they went along. Then it started to leak. I switched the shut off valve off and instructed the client, in writing, that it needed to be rectified by an OFTEC reg’d and insured installer immediately. The cottage was at the bottom of a steep valley with a fast flowing stream at the front of the house. You can imagine what 1800L of oil into that would have done, environmentally, let alone cost repercussions, and even though that tank was never touched by us, I still felt it was my responsibility to make the client aware of the massive dangers that were in front of me, ( even though it was caused by the complacency of others ).

As long as it's not in @daiking's hot tub i'm all good.

Make it so. ?

AONB / conservation / listed?

When you're finished, we'll all meet up and go out on the piss Could do with a blow-out

sending you a high-5 down the line. She any good at grouting?

This should all land squarely on the shoulders of the OFTEC installer who commissioned the new tank / de-commissioned the old one. This is ENTIRELY their fault and should be coming off their insurance.

Just knock the bloody thing down already !! Dig the shite out and dispose of, and then infill and compact, and rebuild. The writing is on the wall.......the house is on borrowed time. Oh, and don't listen to rumours, most are utter bollocks.

Yellow stains will be the LEAST of your problems!!!!!!!

Flat, not shiny. I’d have said mirror otherwise ? Big walls will always have some kind of undulation, but for every 2.5m run @ 2.4m high you should be expecting a very good finish over the given area. Beware the spreads that don’t lay opposites on and let them go hard before then laying adjoining, eg spreads who put a whole room on ‘wet on wet, and then there is very little they can do to get all the internal angles and lines crisp and straight. Yes, they do make internal corner trowels, I own one, but not many people can use one without doing more harm than good. 3 sets a day is good going, just depends how old your spread is ?

You can use a small fan heater to kick start things if you’ve ever forgotten to turn the UFH on so no big problems there.
