You don't mean that. It could be 7 kWh, or 168 kWh. (not kw, or kwh)

yes, and if I was building, I would take time off work and spend it all with tapes, tars, adhesives, rolls of membrane, GRP and a home made tester. I am surprised that the volume manufactures don't have the kits available and test places as they go. £5k of kits, £35 k/year to employ someone. 1000 houses and the cost is £40/house. 160 kWh of electricity.

Totally reliant on the workers though. I am not saying that any other type does not suffer from bad work, but factory built is better than onsite built by design, why it is done that way. Ideally the @50Pa test would be 2 not 10, and a £100k cash back insurance if it fails a retest after a decade.

That is the problem though. It needs extra work done to it. And who knows the long term performance as few people will ever get a second air test as it costs £250.

Brick and block is another term for leaky. Not everyone agrees, but I would put more insulation in the floor. The U-Value may look impressive, but the UFH means the temperature difference is higher, si overall losses are higher. It is losses that are trying to be reduced after all.

Yes, we implemented that at 5he college 20 odd years ago. Also meant we could quickly stop illegal content being shared i.e games.

Yes, used to teach my students that. Same with compressed images i.e .jpg Encrypting is different. Taught them to do that as well.

What on earth on? You you constantly stream TV 24/7, on multiple devices. Like energy usage, much can be done to reduce usage. There was a nice sketch in Green Wing where Martin sent a large file by email and blocked up the system, causing some important records to be delayed, a man died, or not, we never found out.

I was taking the piss a bit. And dispell the fake news that @pocster put about that all I do us download porn. More seriously, when I send large files (not video or pictures generally), I compress them. Does this happen automatically on the interwed? I am sure if we all halved our transmission sizes, we would all be better off.

Gasoline from my local Tesco is £1.42, so 15p/kWh. Cheaper than mains electricity.

Subsidies, grants, incentives etc are there to help the transition from fossil fuels. They are really designed to help the manufacturers and installers, not the end user. It is, and not in hindsight, a shame the the original FiTs was so generous to the end user. This has had a negative affect in future purchases of not only PV, but also micro thermal generation. So linking grants (or whatever) for HPs only if another renewable technology is installed will kill the market dead. The biggest problem is that the general public still think that solar and wind farms cost several times more than the equivalent gas generation. This was true 15 years ago, but they are now the cheapest options (UK windpower would be even cheaper if we installed on land, but our new agricultural policy has stopped that, as did the previous policy with the moratorium on land based windpower). What will change people's minds is legislation. When you only have the choice of electrical, the choice is resistance or heat pumps.

I have jut looked at my phone data usage (I use the phone as a hotspot). Since the 10th of the month, I have used 619 MB. So around 60 MB a day. Should I upgrade to 5G and pay an extra tenner for a faster service?

Houses should be symmetrical. Simple, clean design is a winner.

There used to be a saying about an automated machine tool that could be run by 'one man and a dog'. The man watched the machine, the dog was to stop him touching it. If the builder won't call when he has a problem, he won't press a doorbell. The problem is the builder, not the communication technology.

That bit depends where you are, it is geology dependant. GSHPs should really be called water source heat pumps.

They are just the same as a split ASHP really, except the bit with the fan is replaces with a pipe. But, just like a split ASHP, the compressor and pumps can be in an outbuilding. These are the sizes of the two Kensa pumps H X W X L (mm) 515 (H) X 480 (W) X 360 (D) 585 (H) X 610 (W) X 595 (D)

That is just bad installation really. Not as if you would put an oil furnace in the living room. There is no real reason they have to be inside, just lazy plumbers really. Easy enough to build a small plant room outside, most units are pretty small.

Neat idea. What do they do if UFH pipes are going the the doorway, just cut notches out to go over the pipework?

That's interesting, can you pop a sketch up please?

Worth reading old @Ed Davies blog about it. https://edavies.me.uk/2017/03/vapour/

I grew up in a place with concrete roads, don't remember any cracks like this in them. Mind you, the surface was not flat, was more a load of semi-circular ridges.

I am interested in what causes this cracking. Is it just too much water in the mix, or the wrong temperature, or even the wrong mix of aggregates. Or maybe the UFH pipework causing a stress raiser. I can understand that a very large slab may have problems, why they put in expansion and contraction joints. But most houses are not huge in the scheme of things.

We had an exceptionally mild autumn, so your screen should be OK. The 1mm/day is a bit of a hand wavy number. Wet processes in buildings cause so many problems. It is about time the industry moved on and stopped using them.

Send me a copy and i shall see if it is rights protected. Though I think you can copy and past on the Kindle.

As a sanity check yes.
