I shall ponder this, but it is probably just a case of putting in a time delay to allow the RH peaks to settle.

Yes, I do remember fitting a pump (still working) and a mixer tap (gives no problems), to my existing system over a decade ago. Oh and when I had to change my 32 year old cylinder, it was £220 (from your helpful mate) and I got quite a few quid back on the old one. KISS, it is the only way.

Wasn't it done on some grant scheme, so we all have paid for it, already.

I think our old mate Jeremy Harris, who is just west of Salisbury had a list of people he would recommend. The lit may be on his website. http://www.mayfly.eu/

I am not sure about SAP, but seem to remember that there is no RHI on A2AHPs. This is because they are cheaper to start with.

They will probably come and arrest you for attempting an RHI fraud. The NIs and Spanish are the world leaders at this.

It is to do with the nature of phase change materials. When a block of ice changes to liquid water, there is a phase transition at 0°C. During this change, the energy that can be released. Water as a liquid has a specific heat a capacity of 4.2 J/g.K, when it is solid (ice) it is 2 J/g.K When it is actually changing state, is it ~325 J/g.K Now the Sunamp does not have water as the phase change material, so the numbers will be different, but it works on the same principle, it draws the majority of the energy while it undergoes transition. This is why it is hard to use Temperature as a state of charge indicator. It is not linear, but stepped i.e it drops at one rate, levels off, then drops at another rate. The same is true for charging it up, but in reverse, obviously.

You can make it even cheaper to self install if you use a vented DHW system, none of that G3 nonsense. And the kit is cheaper as well, which annoys plumbers as they cannot add on such a large mark up. https://www.gledhill.net/master-pressure-get-g3-qualified/

You may find it cheaper overall to not use the MCS/RHI route. Have you done the costings yet?

Because of the thermal losses through the floor and into the ground. Just a case of working out the losses and see what comes out in the wash.

You may find that UFH is not the best option. Have you considered 'skirting radiators'?

Our Jeremy Harris put in solid copper between his ASHP and the distribution manifold. Then found it noisy. He then RTFM and found that the reason it came with a coiled flexible pipe was to dampen the sound.

You have to make sure there is no noise transmitted via the pipework. But basically, make a hole, reseal all membranes, stick pipes through and seal the gaps.

My view is that it is always best to insulate pipework, that reduces uncontrolled losses. Makes no real difference what the pipes are made from with regards condensation, that is a combination of RH and Temperature. Mechanically it is a different matter.

More a copy than a derivative.

Because Unix was locked down too much, Linux came into being. Linux is not UNIX.

I do notice that MS named an OS 'Snowball'. Bet that was fun when searching for it if the Adult Filter was switched off. Especially if you added in "Work Group". (note, not much interweb about in 1993, was nearly all porn)

Well from the Mac list it is Lobo, short for what the users have, a lobotomy.

So shall we compare? List of macOS version names Here's an overview of every version of macOS and Mac OS X Apple has released. You'll find a complete list of OS X version code names, along with internal code names (if available): OS X 10 beta: Kodiak - 13 September 2000 OS X 10.0: Cheetah - 24 March 2001 OS X 10.1: Puma - 25 September 2001 OS X 10.2: Jaguar - 24 August 2002 OS X 10.3 Panther (Pinot) - 24 October 2003 OS X 10.4 Tiger (Merlot) - 29 April 2005 [OS X 10.4.4 Tiger (Chardonnay)] OS X 10.5 Leopard (Chablis) - 26 October 2007 OS X 10.6 Snow Leopard - 28 August 2009 OS X 10.7 Lion (Barolo) - 20 July 2011 OS X 10.8 Mountain Lion (Zinfandel) - 25 July 2012 OS X 10.9 Mavericks (Cabernet) - 22 October 2013 OS X 10.10: Yosemite (Syrah) - 16 October 2014 OS X 10.11: El Capitan (Gala) - 30 September 2015 macOS 10.12: Sierra (Fuji) - 20 September 2016 macOS 10.13: High Sierra (Lobo) - 25 September 2017 macOS 10.14: Mojave (Liberty) - 24 September 2018 macOS 10.15: Catalina (Jazz) - 7 October 2019 macOS 11: Big Sur - currently in beta

That is his daily diet.

We all know that your favourite flavour was 'ice cream sandwich'.

This is an interesting problem as it does depend on the layout of the loads. If the 200m cable is devided by the number of primary loads, the 16A, evenly i.e. at 12m intervals, then I calculate that a 42mm2 cable is needed to keep the voltage at the very end above the minimum of 216.2V (230V - 6%). One problem is that if the initial voltage is already at the lower limit of 216.2V, or close to it, then you are stuffed. I may try and add in some random 'diversity' to see what happens. (I am using 19 ÷ by C.S.A [mm²] to give ohms per km. ÷ by 1000 for resistance per meter., then Ohms Law)

Are supplies usually low this time if year? Heating season is starting after all. Or is it BREXIT/COVID stockpiling, either by customers or suppliers? Has the price gone up dramatically?

Cats don't mind living outside all year. So where is the problem.

Is that thinking outside the box ? Outside the kennel.
