Pour hot bitumen into the holes. End of problem.

Octopus Energy tariff into an decent sized UVC for 4 hours a day on electric only? Would need 6kW of immersion minimum and sizing the UVC so it never went fully cold. Room for possible daytime PV input too then. Plumbing in for the gas just for DHW would be expensive on capital, but a small system boiler for everything ( doing away with the ASHP ( and certainly any foolish attempt to heat water via the 'Aga' )) would be best option.

Categorically, no! The MBC timber-frame offerings that I have been around are graveyard quiet ( the ones with 300mm of Warmcell blown in to the walls and 400mm of Warmcell blown into the roofs, to be precise. Don't confuse sound created by walking through a property and hearing noise from outside, they are two very different things.

The Cardiff branch supplied for a Swansea job of mine, and the prices were staggeringly expensive. Spoilt second wife half the age of rich client said that's what she wanted, so off he went with his cheque-book like a good little boy. Total waste of money, just don't be lazy and shop around for the same products by name and you'll save thousands. @Taff Ask your other half if she likes setting fire to money, as that is what you will be doing, plain and simple. A well thought out and neatly installed room will look the same, regardless of what you spent on the items. I have many champagne jobs in my library achieved with lemonade money, and they still look a million bucks .

Point being, fit the right amount of PV if you’re not getting paid to spill over back to the grid. Agree on the uplift, but MCS is more than just getting paid, it’s insurance and diligence also, eg to ensure the array will perform admirably vs the effort / cost to install it

+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.

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. ?
