I think the one I had had a PEAK rating of 7KVA, but that is loading all 3 phases. So the peak load on one phase was about 2.3kVA not even enough to run a kettle. And that was the peak load, not continuous. If I recall it had a copy of a Honda engine powering it. as @Nickfromwales says dispose of it and buy the best single phase generator you can.

That generator is less useful than you think, unless you want to drive a 3 phase load. I bought one from a man selling it out of his van, brand new, identical to that but a different silly name. Each of the 3 single phase outputs are a surprisingly small rating and you CANNOT connect them on parallel to get more load, so unless you are going to rewire the caravan with a 3 phase board to split the loads it will be very limiting. Once I realised how rubbish it was I advertised mine on Gumtree and sold it for more than I paid the man with the van.

This is a BUILDING CONTROL fail for not checking they were not being hoodwinked. Then having found this deception, crawled over every mm of every single house on the developments looking for other breaches of building regs.

Yes it is heavy. Getting the parts up to upper lifts is hard work.

I am watching with interest as I too have render issues (remedial work about to start very soon) Are you footing the bill for the remedial work or is the original supplier paying for the rework?

If this is a wide sliding door, I would want at least 8mm spare clearance to allow for sag in any lintel above the door.

Our relatives in Australia get ALL their water from rainwater and use it for everything including drinking. The big difference is they have a "wet season" and get a lot of rain in a short time. when it rains they let it run off for a bit to clean the bird muck etc off the roofs, before diverting it to the tanks. It is never going to work so well here when so much of our rain is short showers or drizzle so no chance to clean the roof before starting collection.

The other concern of Rationel, particularly if rendering, is they do not want the gap between the timber frame, and the aluminium cladding, getting filled up with render if you render straight to the window and squash it down against the window. I don't see a problem with timber cladding up to the front of the windows ali cladding, that is exactly what I have done. There is no risk of blocking the gap between the ali cladding and timber window frame and it is in a ventilated space,

Just what are you hoping that will achieve?

The "problem" coming up is the government have decided to outlaw fossil fuel boilers to decarbonise home heating. A very worthy aim given the need to reduce / eliminate CO2 emissions. But I don't believe it has actually been thought through. It is just an ambition, and a stick (banning new fossil fuel boilers) but no actual plan of how to achieve it. Sticking an ASHP in every house is not the solution. It needs a LOT more than that to much of the UK housing stock to properly insulate it and draught proof it etc. I don't believe government subsidised schemes will deliver well engineered solutions that offer good value for money for either the home owner or tax payer. And then, when all the homes are heated with heat pumps, all the new generation capacity installed to power them must not use fossil fuels otherwise you have failed in reducing CO2 emissions, just moved it. And all this happening when transport must also move to non fossil fuels. Just where is the plan for all this non fossil fuel extra electricity generation and upgrades to the distribution network to make it all work?

As I understand it , for a "level threshold" you are allowed a 15mm step. What I am reading is you will have an 8mm step down followed immediately by an 8mm step up. I don't see an issue with level access regs, but what stops it filling with water?

I think the same applies. For a new property the access has to meet requirements and turning space etc.

Yes. I know someone who built a house served by a shared private road already serving 2 houses, and to add his 3rd house to the same private road, he had to update the visibility splay to current requirements. Also up here if it gets to 5 properties, you are expected to upgrade the road to highways standard and it is then adopted.

Compared to what? A combi boiler? Sure it has limitless hot water but I am staying in a property served by a combi and it is lousy, the variable temperature of the hot water, and the loooooong time it takes to delver hot water when first turned on. Give me a hot water tank full of 48 degree hot water that arrives at the tap quickly and is a constant temperature regardless of flow rate any day. I think the big issue with ASHP's is there are a lot of people (and cowboy installers) expecting to swap a gas or oil boiler driving radiators for an ASHP and expect it to work. It won't. This is going to lead to a lot of people disappointed with ASHP's and plastering the internet saying how rubbish they are rather than how rubbish the system design (or lack of design) was.

The bottom of the tundish should connect to a 22mm or larger pipe leading out of the building to a drain. So being polite, this is "unfinished" thought you normally install this drain pipe early on before all the boxing in.
