Perhaps not as much as you might expect... 3-5000 Ton is around 4.5 million kg. If that was raised to a height of 8m it would store.. Energy = mass*height* gravity = 4,500,000 * 8 * 9.8 = 353MJ of energy. The stored energy would have to be used while the tide is going out allowing the vessel to descend turning a generator as it does so. That's 6 hours. If it was "discharged" at a continuous rate for 6 hours the max power output would be... Power = Energy/time = 353,000,000/(6*60*60) = 16kW approx. Obviously it could deliver more power for shorter periods - say 32kW for 3 hours or 64kW for 90 mins. In practice it would be a less as you can't capture and convert all the energy to electricity. If you were thinking of using a real boat for this you would have some problems. The boat would need to be supported somehow when the tide goes out and the water disappears from underneath it. It can't float down as the tide goes out because that wouldn't allow you to capture the energy. Tidal barriers like that proposed for the river seven work because the amount of water raised would be much larger. The real problem is that gravity is quite weak.

Is this the same thing for £85 or is it a different version? https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fp%2F22025972786

+1 to check the pump direction. I looked at the manual but it's not clear. The drawing that shows the permitted installation orientation suggests it might be installed pumping downwards by mistake. However if that was the case I don't think the flow meters would work?

Does the ufh loop pump stop or does it keep running when the fault occurs?

Some manifolds have an "over temperature stat" that limits the floor temperature to prevent damage to some types of flooring and burnt feet. Perhaps this is set too low?

Cut it again?

Tried eBay? uPVC £5 but collect from kent https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F113889566322

Some suggestions on bending chrome plated pipe.. https://www.diynot.com/diy/threads/can-i-bend-chrome-plated-copper-pipe.243179/ Edit: Oh I see you've done it.

We opted for a mix of timber/weather boarding and brick with an oak frame just at the front. Oak doors. Sorry can't post a photo at the moment.

The pressure for the test is usually quite low. To temporarily seal one 50mm pipe I tapped a poly bag over the end.

A man in Wales has legal battle regarding a shed on wheels. It seems he won because he was following advice given by a planning officer! He lost his original planning case and enforcement was initiated which ended up with him loosing before a magistrate back in June... https://www.bbc.co.uk/news/uk-wales-48703677 Now he has won at Swansea Crown court. https://www.pembrokeshire.gov.uk/newsroom/shed-on-wheels-conviction-overturned An appeal judge has overturned a decision by a Court which fined a Milford Haven man for breaching planning regulations.James Kershaw of Pill Priory, Lower Priory, was convicted at Llanelli Magistrates Court in June for not complying with an Enforcement Notice issued by Pembrokeshire County Council.The case centred around a sh to which wheels had been added. It was claimed by the defence that the addition of wheels meant it was no longer a building and not subject to planning rules. Mr Kershaw was fined £700 but subsequently appealed the decision by District Judge Chris James and was successful in getting the conviction overturned. At the recent appeal hearing at Swansea Crown Court, documents were submitted by Mr Kershaw which proved he was relying on the advice of a planning officer who had told him that providing he placed the shed on wheels, there would be no issue with planning and enforcement. The Appeal Judge said it would bring the administration of justice into disrepute to allow the planning authority to prosecute Mr Kershaw after he had merely followed advice given to him by an employee of the Council. In winning the appeal, Mr Kershaw was awarded costs. After the case Pembrokeshire County Council’s Cabinet Member for Planning and Infrastructure, Phil Baker, said: “While accepting the Court’s decision, the Council wishes to point out that the ruling hinged on a legal argument over process due to the discovery of advice provided by a planning officer given to the applicant during the planning application. “The Appeal Judge determined that this subsequently invalidated the Authority’s ability to bring a prosecution.” Councillor Baker explained: “The Council is keen to stress that it should not be accepted that the outcome of this case implies that by adding wheels to a structure that it is no longer a building and therefore not subject to planning regulations.” He added that the planning officer in question is no longer employed by the Authority.

I calculated there are 56,000,000,000,000 squares on the planet. I don't know how fast their web site would respond to a look up request but at one a second it would take 1.7 million years to look up all the squares! I think there must be an algorithm rather than just a big database.

It looks like there are also solder types..... https://www.ebay.co.uk/itm/End-Feed-to-Female-BSP-Thread-Coupler-Copper-Pipe-Connector-Straight-Adaptor/153046602972?var=452873484642&hash=item23a249d4dc:m:mnrVkHLcUYni5sxJA4mTCVw but take care because after soldering to the pipe you might not be able to screw/unscrew them from/to the rad. eg Pipe has to rotate.

Google found... https://www.stevensonplumbing.co.uk/radiator-valves.html but is that BSP or BSPP or ? See that other thread. Anyway that led to... https://uk.rs-online.com/web/p/products/2858716/ and https://uk.rs-online.com/web/p/compression-fittings/2858687/ RS may not be the best place to buy them from but at least its a start. Those are chrome plated. Available in brass elsewhere.

Oak sign I ordered about 10 days ago arrived today. Got it from this ebay seller... https://www.ebay.co.uk/itm/Solid-Oak-Personalised-Wood-Sign-Carved-House-Name-Gate-sign-great-as-present/181677893530?ssPageName=STRK%3AMEBIDX%3AIT&var=480633585620&_trksid=p2057872.m2749.l2649 Quite a good price compared to one I got 12 years back. The letters are V cut and very crisply painted. I asked for it unvarnished so I can use Osmo UV protection oil on it.

I wonder what percentage of the UK population would like to retire to a quiet place in the countryside?

What I would check is... If water did get onto the cable would it run down the cable into the inverter or do the cables curve back up and go into the bottom of the inverter?

I wouldn't worry too much. Roofing felt/membrane should drape between the rafters so that it's not tight up under the tile battens. The hole doesn't look like it's at the bottom of the drape so I think it's unlikely any water will get in.

Spare a thought for Amazon delivery drivers trying to find your house in the dark... Make it illuminated and big enough to see from the road without a telescope :-)

Yes see 3.3.4 in vat 708. https://www.gov.uk/guidance/buildings-and-construction-vat-notice-708#section3 It allows among other things..

During our build i picked up a load of samples of engineered oak at a self build show. When I got home and put them in natural light I found a very wide difference. They all looked good at the show but some were virtually orange at home. Shop around for appearance as well as price. Perhaps even buy one pack to lay out in the room. You can buy it ready finished or unfinished for you to paint yourself. We got ours prefinished but if you do the latter I recommend Osmo hard wax oil. Also consider the orientation carefully (across or along the room).

+1 See the reclaim form... On page 13 it days..... And on page 14 it gives some examples of what can be claimed and one item on the list says.

YouTube showed me an advert for a compressor from lidl. Looks like they have a bunch of tools from Sunday. Not sure if link will work.. https://www.lidl.co.uk/en/MiddleofLidl.htm?id=1177&week=1
