We used to stick the caravan roofs on with double sided tape. Was good stuff.

Stainless steel has a thermal conductivity of about a third of regular carbon steel. About 15 W/m.K. Nylon 6 is about 0.25 W/m.K. Basalt wall ties are around 0.7 W/m.K.

That comes down to how you want to measure it. Think insulation can look fantastic when expressed as a percentage.

Was it exceptionally rainy today? If so, could it be caused by a failure somewhere else i.e. gutter. There should not be a great deal of difference between your system and a GRP system as they are both reinforced resin systems.

Is it an interactive spreadsheet i.e. useful to others, or just a final statement of what you intend to do?

I use Lumberjack PU adhesive, but at a tenner a tube, it would be cheaper to buy some 18mm OSB.

I think £5000 is reasonable. I will have a few spare hours once I get the first coat of gloss on my window frames. Have you looked for a copy of BRE 497?

I have some size nine climbing shoes, and a harness.

The PV generation meter is separate to the supply meter. But I suspect you are right that the don't want the hassle.

We have discussed it on here. https://forum.buildhub.org.uk/topic/33386-thermal-bridging-psi-values-for-isotex/#comment-491162

You would have to check the specifications of the inverts. There should not be any reason, other than capacity limits, why you cannot have a 3 phase system and then add another 1 phase system. That is how microinverters work together after all. You will need 3 phase net metering or you run the risk of some power going down the line without being paid for. The FiT system allows for upgrades, as it can take additional generation into account, and subtract it.

Yesterday I posted up a link to PM and how Lord Haughty said that ASHP don't work. Well Evan Davis was on the WatO saying they had so many calls they are doing a bit more on it tonight. So Radio 4 at 5PM. Listen to Ed Reardon instead. Pippa Hayward is on it.

I shall have a look at what my spreadsheet churns out when I get some time. Pulling kitchen part at the moment, been years since it was properly decorated.

What heat pump you got and how large is your PV now? I have a spreadsheet that needs more data.

It shouldn't. While water is often the blowing agent for PU resins, the oxygen gets stripped of the two hydrogen atoms. The free oxygen and hydrogen atoms then combine with carbon atoms that have a free electron. Then you get a mix of CO, CO2 and CH4. Why you are told to keep the area well ventilated. Thermoplastics use hydrazine, much more fun.

Have you read this?

Trouble is in the UK, the politicians and general public's understanding of science is so poor, they could not get a project like this off the ground. Just today, on PM, there was a bloke who sells ASHP telling Evan Davis that they don't work in Scotland, use more electricity and cost more to run. I don't think Evan Davis believed him.

With all the serious illness above, it makes worry about an urban fox rather trivial. Giles' Grandmother sorted it.

Isn't that the least efficient though, usually only capturing around half of the CO2. There is an energy cost to doing it as well. And globally there is only 0.1% captured. That is lost in generation variation. I can save a thousands of my energy usage (about 3 kWh) by using my oven for 3 days less a year. CCS has been talked about for decades, all are still just trial sites. Cheaper to build a solar farm.

Won't we do the same to them. The British built the Hong Kong power system after all. The Americans have STUXNET and seem to know how to get it onto networks.

Why, reduces energy usage. Mainly because he has 3 properties and could well afford to do a simple and cheap loft upgrade. That fits in with your But they don't need more, they need to loose less. That is what we vote for though. All that information is already reported to the government. You can get the spreadsheet from the ONS if you want to. Not really, the utility value to the nation is very different. But we have seen that people will still travel when fuel prices double. So there is a lot of slack to be taken up there.

I know very little about them, Cornwall is not a target area. I am sure that there are top members that will have a transition plan though. Was chatting to the guy who owns net door. About 2003/4, he got a free loft insulation installed in all 3 of his properties. This strikes me as wrong. The easy way to do it is that gas can only be supplied if your property uses, based on meter readings, less than a fixed delivered amount i.e. 70 kWh.year-1.m-2 (or whatever). Then it is up to the home owner what to do i.e. sell up and move, upgrade.
