My Kitchen / diner is 7m by 5m so as it happens 35 m2 Mine is working just fine with one inlet at the kitchen end and one extract at the dining end. Both fed by twin 75mm ducts. I will eventually fit a recirculating cooker hood but I don't have one at the moment. So ithink you can forget the single duct extra inlet in the middle of the room.

What is the size of that living / kitchen / dining room?

I suspect the internal thermometer (2) is reading low. Can you see where it actually is and get your thermometer in EXACTLY the same place? But irrespective of that, there must be a parameter that lets you set the target temperature higher than 45 degrees.

So that looks like it is running to a target temperature of 40 degrees, or 45 degrees with the weather compensation on. What is the issue? If you want it hotter, set the demand temperature hotter

If it's just wanting to get a caravan past the bollards, could the caravan delivery wagon not back up to the bollards, then arrange the unloading ramps the other side of the bollards? It all comes down to are the bollards taller than the load deck of the wagon?

What is the actual width of that bridge? And the weight limit?

What's the extra inlet vent in the middle of the kitchen / diner for? I would have thought inlet at dining end and extract at kitchen end was enough. What is the stairwell thing? If there is a stairwell then there is an upstairs so where is the vent plan for that? Is it a bedroom at the moment with some plan in the future to convert the loft? Agreed put kitchen / diner vents on the centreline of the room, if for no other reason than aesthetics.

You could also argue why do I as SE pay pretty much the same NI as a PAYE employee? I don't get any SSP and in normal circumstances it is virtually impossible to go from SE to unemployed and claim any form of benefit.

I have seen statics as short as 20ft but they are not common. Even the smallest are 10ft wide, but when it's on a transporter that width is a few feet off the ground if that makes a difference. Here is ours arriving How about a large touring caravan, they are not usually over about 8 feet wide which might make all the difference?

Yes that is the coupling. Chamfer BOTH ends of the pipe really well, use plenty of lubricant, slide the slip coupling onto one pipe all the way over, offer the 2 pipes up and then slide it back. Don't forget to mark the pipe so you know how far to slide it back. And just to say it again a really good chamfer and plenty of lube.

Am I missing something? What you want is a slip coupling in that straight section, so you assemble the two ends then join together with a slip coupling. I would use a push fit slip (not even sure you can get a solvent weld slip coupling)

I can't now find a builders merchant that is still open, so getting materials is now next to impossible.

Since the SE grant is by invitation, perhaps any of us that get such an invitation should post here to say so. I have already had an email telling me about the scheme. Have you @pocster ?

That's my standard procedure now.

I must try that as every time I go to the local tip, the engine oil recycling tank is perpetually full so I bring it back again. I have several gallons of the stuff going begging.

Cat litter, but why so little of it?

I thought this was going to be like the ones on you tube where someone tries to take a tree down like that, and the tree lands on the truck.

Watching with interest. My little brain is struggling with how you get three products from 2 electrodes.

Take one of the covers off, you should find some copper pipe inside you can get the thermometer onto, or even onto the output pipe of the heat exchanger. Turn off all the weather compensation and just set it for a constant flow temperature.

Ha ha, I hadn't spotted the half a pair of shoes, so that surely must be the right answer.

10+5X4 = 30

Yes, I used 11mm OSB behind plaserboard where I knew I would want to screw stuff to it. Works fine.

I am not sure you declared that correctly. My end of year tax calculation shows: Profit from self employmet £xxxx Profit from UK land and property £yyyy Income from UK pensions £zzzz If you have declared rental income as "self employment" I am not sure that is entirely right. Or perhaps I am the one that miss read the guidance?

So use that same thermometer to measure the temperature where it leaves the heat pump outside.

Mine (different make) gets to 50 degrees even at -10 outside. Did the installers check the water flow rate?
