Thanks very much indeed @SteamyTea This bit clicked 10K is 10 degrees Kelvin isn't it - I hope (?) And I conclude - hesitantly - that water releases its heat to the environment in a non-linear way . It releases its heat more quickly at first, and as the (its) temperature drops, the heat is released more slowly. The thing that gets me is the term in this context is 'specific' Is the word 'specific' used in this context as - specific to water ? Specific because water will (or any material will) release its heat to the atmosphere at a rate specific to that material ? As below from your first post above In the example you give (of water from a kettle cooling down) the water will be giving up its specific heat more slowly the cooler it gets because as the water cools, it has less specific heat (energy) to radiate(?) to the atmosphere ?

Well, @Iceverge , those two last posts of yours are one reason why I keep coming back to BH. Thanks.

Ah yes, Context - always important: as In Danger! No Swimming Allowed! OR Danger? No, swimming allowed. The difference - either an exclamation mark or a question mark - is used to match the context. Here swimming is fine - but don't swim there. The person putting up the correct sign knows how to read the context. Because of thousands of things in my life experience, in terms of swimming, I can make a good guess about which sign to display. But I'm clueless about heat capacity Can you (or anyone) start me off by giving a short simple list of contexts and the most appropriate measure for those contexts please? Thanks. For example ; How about - choosing a hot water tank .... or comparing SunAmp 'batteries' .... or storage heaters ... or a kettle (?) I'm not even confident that I'm asking the correct question - if so tell me.

Thanks for posting this @SteamyTea , I struggle with stuff like this, so - for me - this a useful first step. I like to start stuff with a clear end in mind. For me that would be a clear idea of why I need to know about the Heat Capacity of (say) a tank of water? What does knowing that measure give me to assist my thinking about the tank of water Once I know that, the next issue is - which of the two measures (Volumetric or Specific) should I use ? And more importantly, once one is chosen, what is the rationale for not using the other measure ? Or maybe - is there a simple rule when it is better to one and not the other? Thanks anyway

Gary which through-wall fittings did you use? I have two juliets to fit quick-as-you-like (or a slow painful death is in prospect)

I've asked a colleague - sparky - the same question: lots of tooth sucking. PS, lovely house....

I don't know anything about the company, but you will pay for the windows - at least in part - using a credit card, yes?

SWMBO is writing an Artificial Intelligence strategy document for her Department at the Management School at our local HEI. My mind turned to Buildhub and drafting our own Planning and Design Access Statements rather than employ someone....... This is what I asked Chat GPT to do for me And here's Chat GTPs answer Hmm, well thats a start - not much difference between that and a commonly available template. Downloads a random Design Access Statement Template ( in this case Zummerzet war dem Zider Apples grow) That template asks for the Design Principles that have informed the design - thus Delving at random again within this response to look through Chat GPT at which Environmental Considerations. should be considered (Point 2 above) I asked this question and Chat GPT replied and because I could not resist it ( if you've read this far, you're there before me aren't you ) ......... Tell Me oh Chat GPT, what's Thermal Mass then Ouch.

Hello, welcome. I live within sight and sound of a narrowboat mooring - competing aggressive cockerels, woodburning stoves, demented dogs, and very pleasant owners. Each WBS on the mooring produces a significant amount of heat, so much so that they all stain the paintwork on the exterior of the hull. One boat has two such stoves, and a Webastow (sp wrong?) diesel heater. Makes me wonder how many fish congregate under that hull : the local Goosander seems to snack there often.

Well there will be some insulation , so it's a good idea. But I bet the seal all round the edges of the door will help just as much - or more. Drafts work all day every day. Don't believe me? Just ask a woman.

You'll be proud of me, @SteamyTea. I've gone through your post above ( the one with all the numbers and and threatening signs [ like these] )at least half a dozen times and I think I'm fairly close to understanding it ..... sometime later this year. I'm a bit of a slow learner really.

I doubt whether the approval process before being uploaded is standardised across all LPA Content Management Systems ( their Internet 'presence') . So we don't know is the fairest answer to your question. I have a strong feeling - but no evidence - that LPA Planners are not allowed to vary the content of Consultee responses because the LPA Planner is not qualified to do so. I'm sure that the Planner (or a deputy) could delay uploading the Consultee response - or ask for it to be varied in some way. @Bournbrook , many of us here have also been through the mill in which your psyche is currently being ground to dust. The only way I worked through this particular test was to over-occupy myself with other projects and indulge myself in too much sport.

Yes. The manufacturer's guidelines.

We - facing a similar situation - wrote a polite but firm letter to the HoD and copied the relevant Councillor in to the communication. The Councillor did his bit. Wyre Borough (our Council) then outsourced their backlog to a group of Planners (some of them ex- Wyre Borough I understand) who had set up in business working for themselves. It wasn't worth taking things any further (a non-determination claim) because Wyre had taken action to try to reduce the backlog.

Interesting @JohnMo. I have the opposite experience. 8mm gap (which is now 12-14mm : shrinkage ) and not a wasp in sight. That doesn't mean there won't be any, but - to date - none. I asked a local pest-control guy (pub acquaintance) to come and look. He had an interesting take on the issue. If the gap is large enough there will be lots of air circulation - "Wasps don't like living in a gale mate" was his memorable one-liner. Our cladding is Siberian Larch (now contraband: you can't get it for love or money here) set on 2 by 2 battens on top of felt (Vent Pro Matt? £1500 for a 10m by 10m house. The felt is certified for a 30mm gap for about 30 years. Not sure I trust that but hey it's up and it works.) PS the timber was 14mm ( now about 12-13mm)

Thats the trick isn't it John .... self consumption. I have a measly 3.8kWp and a 14kW SunAmp. That sucks up every last drop of solar that I can produce and then I export whatever is left. I'm eyeing up our new wall for potential to use vertical panels : standing there earlier today in bright sun @SteamyTea's point about vertical panels picking up sun at this time of year is driven home. In a Northerly wind, the pieces of stone are already a tiny bit warm to the touch. I have a feeling that there will be competition for that vertical space - I married a gardner. Maybe I can arrange to provide enough power to light our garden pathways.

Hello, You're in good company. What are you building?

Bitte viele Fotos....... Willkommen

None of us here can give you a properly qualified answer. It's above our pay (£0:00) grade How much money is at stake here a few hundred or a few thousand?

As written, it seems that the SE re-designed something without your knowledge, and is charging you for it . Correct? and in addition got agreement from the basement company and said ; put a gun to your head. It seems to me that I have misread / misunderstood something, or there is a distinct lack of Emotional Intelligence in your team. All it would have taken to avoid this is one phone call.

Clear it pronto. If you have fidgety neighbours, clear it early Sunday morning. Standard practice here in West Lancashire : nobody will be able to do anything about it until Monday morning, and nobody'll visit until Tuesday at the earliest. It is common here to kill anything that moves on land prior to making a Planning Application. I do not advocate that strategy, merely point out that it works.

Quite the opposite of minor. I say that because I sense your starting point was - Never-Done-This-Before-Lets-Give-It-A-Go If thats correct, the job took hours and hours more than you thought it would take (twice as long maybe ? ) The verticals are staggered - and so stronger, less likely to bend. (PS, the second design could be improved by staggering the verticals too) You've realised that modular design is helpful - cuts down the number of cuts needed. All the more creditable therefore. Ermm, I've got some spare MDF - could you build me some .......🫠

What was your cost-control strategy? I ask because I think it reasonable to suggest that all relevant parties are responsible for managing communication about significant change. Or, maybe you had a Quantity Surveyor? In which case ...

The thing is, exposing your thinking here (in the form of a post) is both challenging and valuable. But the final decision is still the responsibility of the OP. At least the guy was courageous enough to post about his heat pump here - and obviously prepared to put the effort in. In @Jeremy Harris terms the '... ignorant disregard for failed ideas ... ' could well be seen as optimism bias.

Well there's force majeure in action for you (here)
