I figured it is a useful starter for ten when people are trying to work out how to size them, even if it leads to oversizing that can't be a bad thing as opposed to under sizing.

How to size an expansion vessel is a question which comes up every now and then and I don't believe this graph has been shown before, I came across it whilst researching ASHP/UVC and figured it would be useful information to have on here:

That would be a neat solution, damned if I know how it could be done though.

This is the drawing I was looking at which prompted me to check the EN type Brett Martin soil stack/underground drainage i had used. Typical that the 'standard' one I used isn't suitable. So, now I weigh up poking a hole through my house in the off chance the TPRV triggers or, I run it to the soil stack and potentially trash all my foul drains?‍♂️ I suspect it would have to be discharging at high temps for a long time to do any real damage - so I'm gonna tap it into the soil stack!

From building regs: 3.60 The discharge pipe should not be connected to a soil discharge stack unless it can be demonstrated that the soil discharge stack is capable of safely withstanding temperatures of the water discharged, in which case, it should: I did start looking into this whilst looking at the tundish situation but stopped as it isn't something I can change now. You can get underground soil pipes made out a different type of plastic which can withstand high temperatures. I'm now resolved to connecting mine up and hoping it never turns into an issue.

@PeterW Will the 40mm high temp pipe going into a standard soil stack be ok if the soil stack is not high temp? I was looking at this the other day and found that doing the 40mm in a high temp plastic and using a Hep2O waterless waste seemed to be the solution. But the 110mm soil stack I have does not meet the high temp requirement, I spent ages scrutinising the BS no. for the Brett Martin stuff I used - annoying, as if I had pre-planned this I could have used the right stuff for the whole drain run. I'm now in two minds, run it into the main drain and hope it never pumps boiling water down there or run it through the wall. I don't want to run it through the wall and I'm thinking that if an ASHP runs at 60 degrees, how can I get boiling water through it - surely the only issue would be pressure being exceeded leading to flow through the tundish rather than temperature? In which case, connecting the tundish to the soil stack should be ok?

You are interpreting my words now to sort your narrative. I did not say I do not understand etc, I was making a point about how data can be presented to suit. Again you are selectively interpreting what I'm saying. At no point have I questioned talk of Boris vs talk of Brexit. Again I was making a point, about how you posted an 'opinion' piece yet felt the need to call me out for posting 'opinion and not fact'. ?

Is not an example of someone spouting opinion and not data - and yet you felt the need to post this? Good for the goose, good for the gander? As for data, I check 'the data' before I post. I just don't have the time to write a thesis when I post. As Joe says, data is just another tool which can be manipulated to suit the authors narrative. Im sure you have seen PP demos which demonstrate this by using the same data, presented in opposite ways to show how supporting opposing arguments can be done.

I don't believe I did say she was a dictator? I made a broad brush statement as the issue is too vast to go into specific detail in a short response. Yet another example of selective stat comparisons - comparing New Zealand to the UK is a joke. A quick look: New Zealand 103,000 square miles for a a population of less than 5 million. UK 94,000 square miles for a population of around 70 million. London has more people than New Zealand. Lets just think about that for a minute, yes I know New Zealand will have population clusters as opposed to even distribution throughout , much like the UK. Seriously though, anyone with a bit of sense should realise that New Zealand will have a much easier time trying to contain COVID when compared to the UK. New Zealand closed its borders, a relatively simple exercise compared to the UK attempting the same thing. Heathrow is the busiest airport in Europe. I haven't the energy to follow this rabbit any further! I wish people would cease using ridiculous comparisons. And yet, Spain, France, Germany etc etc had to go into a lockdown for a second wave well before the UK. I would say that the 'overall' performances are very similar. Belgium, Spain, and Italy all have higher death rates per 100,000. And then we come to recorded death rates. Is every country using the same metric to records COVID/suspected COVID related deaths. No. So again how can we compare how countries are 'truely' performing if we aren't recording deaths the same way? I would suggest that as the Prime Minister it is not feasible to minimise outside contact in the same way that joe public can and still run the country correctly. I suspect the press would have a field day about how he is hiding or some such if he did so. Damned if he does, damned if he doesn't.

Good to hear its working out for you bud. I never even thought to ask about thickening the slab to do away with the padstones, 100% thats the best way forward. Makes it far easier for you. Likewise your dpm under the EPS will help make it easier. Your kore quote came in cheaper too - that's three good things there?

Snap. I did mine in January/Feb this year and poured the concrete towards end of march. The weather was honking, it was storm after storm. I was lucky and it stayed dry during the groundworks part, it was when I started to install the DPM and the mesh that the weather turned crap. Bad times, but like anything they soon become a distant memory. Hopefully you'll have better luck with the weather. Did you get anywhere with your padstones under the slab?

When I tied them to the sheets I just did 4 or 5 on bottom legs and then same to top, like a zig zag.

Yeah the hystools are triangular and available in loads of heights. They are 2m long iirc. I tended to stagger them, much like how you plant a double row hedge, but then I pulled them in slightly so all the ends overlapped by about 150mm - I was looking this morning but couldn't find any pics which clearly show it. Check your height before you order. I cocked up and ordered wrong size. I sized it off the gap between sheets, didn't think about how when A393 bars cross each other the sheet is actually 24mm thick, not 12mm thick.

But then here you are, holding up the UK as a country which has done badly - when as @daiking points out, we've all done badly. The only areas I have read about which have done well are countries under a dictatorship, pre-prepared countries as @joe90 said, and Africa. I will say though, with the countries that have experienced SARs etc and the fact they did ok now - let's not forget, when they went though SARs etc, they did just as bad as we are now with COVID! Africa is an area which seems vastly under reported. Why have they done well where Western countries with all their medical facilitates etc havent? I would suggest the issue lies more with western Liberal attitudes. The minute the government tries to prohibit/restrict they are all up in arms about oppression, government heavy handedness etc. That makes government action very difficult. Christmas is a prime example, they made no allowance for Eid, yet we are for Christmas, why? Because your average westerner will just chin off any restrictions and do what the hell they like. Who then polices that? Look at what happened when pubs were told to shut at 10, everyone hit the local off licence and got pissed in the streets. The government is not the primary issue, people and their willingness to disregard the issue and danger presented is. Equally the Government can't be 'strong' when EVERY decision taken is constantly sniped at/undermined by the press, the opposition party, the SNP etc. This sniping just validates the belief in citizens that the government don't know what they're doing so let's do what we like?‍♂️

Ha, I just said the exact same thing in my previous post. Cowards.

I believe the only silly statement appears to be your own. The COVID situation is far to complex to tie 'success' into the death rate, but that is the headline metric that the press love because it makes headlines and sells papers. I fail to understand how anyone with any sense can do so. The issues are huge, economic consequences balanced against health needs, supply chains, logistics, medical facilities available, transport - I.e. Heathrow is an international hub and the busiest airport in Europe, factors like this will have a huge impact on infection spread which other countries don't have to factor in. The effect that democracy has, I.e. China can do what they like and lock it right down, we can't, New Zealand has performed well, but how can you compare the UK to them? I could go on and on, but there are simply to many individual differences to mention. Equally, where something does work elsewhere, that doesn't automatically mean it will work here. This is another area where anti Boris/Conservatives can take a pop because its an easy target. Always easy to criticise in these circumstances but what would you do differently? How would we ever know that would have worked? Kier Starmer is now playing the same blame game. Abstaining the Labour party from Wednesdays vote because he wants to let the conservatives take all the 'blame. He doesnt have the balls to instruct labour to vote against it but at the same time wont support it? Why. To say we can compare the 'success' of one country versus another is ridiculous and selectively ignores the myriad of differences which influence the individual response of the various governments.

John, I used plastic mesh spacers under the bottom sheets - did look at mars bars but for the qty required they seemed expensive. In the thickened areas where two sheets are stacked I used mesh hystools and tied them to the top and bottom mesh sheets.

People will read/buy into whatever it is they want to believe. Clearly you enjoy reading such garbage and no doubt buy into it. I was going to put some time into refuting line by line this dross but 1. It will have no material impact, those that want to hear this sort of stuff will not be persuaded otherwise and those that don't buy into it will not need persuading otherwise anyway. - yes I recognise this line equally applies to myself in that it would be difficult to persuade me to buy into this crap. 2. I have more important things to do. The only things I will say are comparing countries and how they dealt with covid is generally a waste of time, each country is different and can react differently so if you can name me another country with the same circumstances i.e. population density, travel hubs, laws, health provision, devolved responsibilities etc etc as the UK which have done things better then please do. Secondly, can you provide the evidence which explicitly states that Priti Patel has been found guilty of bullying Civil Servants can you provide a link? and not to some crap news article which spins the internal Government report wording into that which they want it to say. I think the bigger story in this issue is how senior Civil Servants will nod their heads when given instruction by elected MPs and then do what they like anyway.

The argument is being presented by the Press/Euro as a fish issue. That's not the issue at hand it is sovereignty, the minute you use that word all the liberals get up in arms and start conflating 'sovereignty' with xenophobia/racism/nationalism and whatever else you would care to dress it up as. The argument needs presenting in a way that is better understood. The EU want the UK to sign over access to a resource 'owned' by the UK (and by extension UK citizens) into perpetuity. Forever. Why would anyone in their right mind agree to sign away a valuable resource that belongs to them forever? I am sure the Eurozone will be granted fishing rights, but it will be determined by the UK government on behalf of UK citizens and for the benefit of UK citizens. Would the EU sign over oil drilling rights in Greek waters over to Turkey into perpetuity? Don't be daft. This isn't about fish, its about protecting UK resources for the benefit of the UK taxpayers.

Well done, just need to get ya xmas tree up now and then get fat over the festive period?

Ha ha, that might just be the approach I will take. This far my inspector doesn't seem to want to see much, last inspection was brickwork halfway up, next one is pre plaster?‍♂️, works for me. After talking about the build I think he assumes corners arent going to be cut, and they aren't, this is a one time gig and I'm here for life!

All of the little minor niggles with SunAmp are what pushed me to an UVC. I was originally going the SunAmp route when I considered this a couple of years ago under the assumption that by the time I came to buy the issues would be sorted. They don't seem to be, so ASHP --> UVC is now my way forward. The G3 certification is a barrier I could have done without, but tis what it is?‍♂️

I could install it, the problem is getting a completion certificate from BC without the appropriate G3 certificate - not going to happen. Can you get BC to sign it off? There seems to be a dearth of G3 plumbers around here!

Looking at ecodan for the ASHP, 8.5kW with 400l UVC. A buffer for the DHW so the UFH can draw from that. I've got the manuals for the ASHP, UVC and FTC 5, having read them im happy I can do the job. My next task is to merge all the various layout drawings I have to hand into a layout that works. I will then try and plan out where everything will physically go in the plant room before I start installing anything. The manuals were good reading as they cover all the various components needed, why and where. I just need to go back to my sketch and finalise it. It all looks pretty easy to me, just a case of planning properly and understanding what goes where/why.

We have gone for an in frame kitchen from Kitchensfordiy: www.kitchensfordiy.com Not cheap, but looks really nice - on the drawings? Hopefully will look as good when fitted next year!
