Make sure it includes the FTC controller as that adds a few hundred. The best prices I saw were City Plumbing and SWAT, but they wouldn't ship to Northern Ireland. I gave up looking for a reasonably priced ecodan package and instead I'm going for a cool energy shop inverter heat pump, buffer and pre-plumbed 300l cylinder for £4800.

Something like crusher run (25-100mm with fines) might be more suitable as it won't move around as much under load. We used a good 200-300mm thick layer around our site and it has barely sunk or moved. Definitely shop around the different quarries, go on to Google maps and find your nearest, closer generally means cheaper. My nearest is 3miles away and I was paying £10-£12/tonne on 16t loads.

It's actually the complete opposite. Can't remember the name but I listened to a podcast that interviewed a guy from national grid that managed something like future planning. Having 10m electric cars with vehicle to grid capabilities would dramatically reduce the peak loading demands on the network as the combined storage is far more than the grid capacity and it would only take a few kWh from the cars to "flatten the curve" and reduce the peak generation requirement. This, of course, requires properly thought out car charging standards, smart chargers, meter etc etc....

Del Carmen prime, £1.50 ea from SSQ. They didn't even need to grade them.

The guys couldn't work on the west facing door after mid morning as the lead and slates were too hot to work with. They're leaving the south roof until Monday when hopefully it's a bit cooler.

The protection circuits didn't do the job and the cell at the front of the picture overheated and failed - with loud popping sounds and smoke.. was promptly thrown out on to the gravel until it calmed down. Surprised the whole thing didn't go up.

Oh, the battery. My circular saw is really, really hard on batteries. The Makita one does just fine, the copy ones literally melt.

You know those cheap replica batteries on eBay and Amazon? Best to avoid, unless you like your power tools exploding in your hand. Obviously the claimed overload and over heating protection didn't work. The heat probe tape had come free and was no longer in contact with the cells. Happened when I was doing a particularly tough rip with the circular saw. The solder on the other battery melted away on one of the tabs previously. Should have taken that as a warning sign.

It's depressing to see so many dodgy roofing job posts here. Our Slater's have nearly finished, here's their work to date: I've never had a roof slated before, or seen one close up. But I'm very happy.

If you do that, run the 22mm pipe in some conduit though the ground and the wall / floor of the house. Good luck!!!

As I inch further along.... Are the plastic wedges for the panel clamps only required at either end of the array or at all of the clamp positions? If it's the latter I've not got enough and these need to go on today!

Philmac universal connector will get you down to 25mm. Measure the pipe first and get the right coupler. https://plasticsuppliesdirect.co.uk/philmac-universal-transition-joiner-black-27-34mm-x-25mm-3-4-utc-x-pol.html?gclid=CjwKCAjwi9-HBhACEiwAPzUhHC0KLEE9TW7GqBYtsTd-mGS3L714LjIfyElq6ds3PS2bQx3uNQExrxoCziQQAvD_BwE Why 22mm? You're underground so you need to use either 20mm or 25mm MDPE.

Thanks @Marvin. If it makes a difference, the soil pipes enter inspections chambers right outside the building, and flow along our own private pipe to the public sewer.

Architect has specified one stack with an AAV, and the other (main one) with a vent slate at the top of the roof. We can't get a vent slate that will fit between the steel channel sections in our thermohouse panels (200mm), and roofers will be slating there tomorrow so limited options! I've just reread Part N and in all three paragraphs referring to ventilation (ventilation stack, discharge stack and separate vent) state that an AAV is acceptable. Is this correct?!

I managed to set fire to my fire retardant EPS when welding. It's hard to trust any data sheet these days.

You probably won't want to hear this, but going by the sound of things, you'd be better off demolishing the existing house and building a new one. If you are removing the roof, adding a story, building an extension, you'll have the building back to nothing more than a few walls.

I did this for our washing machine, drier, and freezer in our last house. Was bit of a pain making a run of units wider and deeper than standard, but worth it.

We did this on our kitchen as well. My tips would be to buy much more self leveller than you need, and return any unopened bags. Clean and vaccum the floor well, and damp down with water before pouring. Get a mixing paddle for your drill (or hire one) and get a system setup so you can mix and pour continuously. It goes off quickly so it's best to keep it moving. Get the consistency right, experiment with a half bag mix first in a far corner.

It'll be fine. As long as the concrete wasn't washed away.

Can't remember but I think it's a couple manifolds and plenum boxes. Ducting wasn't an issue.

No issues at all with cement, plaster, plasterboard, paving, concrete products, slates, flooring etc. Just have to wait slightly longer then normal. I think it's because so much is made here and there's spare production capacity for quarry and cement products. Only issues I've had are timber and insulation. Both doubled in price and hard to get. Steel isn't far behind, still waiting on stuff from Lindab a month after ordering. Stud wall guy luckily has his own stockpile of metal C studs and ceiling stuff.

Minimal, unless you are using hundreds of them over a small area.

Use 120mm concrete screws for anything heavy or need to be secure, like sockets or handrails.

But I don't see most people charging both of their cars every day though. Most new EVs have ranges in the 200mile zone and people just don't do that regularly. I think the average mileage in the UK is something like 30miles per day. So you'll only be charging a couple times a week to keep the battery in the 20%-80% range. Can you get sets of car chargers that talk to each other that would maximise charging useage off peak in this sort of circumstance? I have a memory of Zappi doing something like that. This is where we need the machines to do the thinking for us

Guaranteed loads of advice here, how much is useful or correct is another matter ?
