They drilled the pilot hole with the 'little rig' the other day. Hopefully the 'big rig' will be there now so they can finish off the 1.5 km bore. https://www.cornwalllive.com/news/cornwall-news/jubilee-pool-penzance-takes-step-1152275

Ah, then the 3 hours is not so odd. I don't know where I got the 200 lt figure from. That would raise the temp by 17°C, so if it started at 30°C, would be about right for a shower. (that does assume that the whole store is heated evenly, which is not the case)

Yes, but it is still 9 kWh being pumped in and only 1 shower taken. I seem to remember that the TS was 200 lt, is that right? And also read on here that it can drop by 20°C in a few hours, which seems ridiculous. Really about time that 'heating engineers' separated space heating and DHW as standard, combining the two is not good in my opinion. This will become more important as we shift over to electrical heating, though we access to so much natural gas that it is not going to happen that fast. Could just set up this system to heat the house and put in a Sunamp for the DHW . Take down the ST and replace it with PV. Not the cheapest option, but if it is burning though 9 kWh a day of electricity to get a shower is costly too.

That much energy would heat 200 lt of water by 39°C. So if your TS was at 25°C, it should end up at 64°C after 3 hours, and that would be enough for about 3 baths of water. I get a bath out of about 1.5 kWh, a shower about a third of that. My DHW cylinder is 200 lt and rarely goes below 30°C and I limit the upper temperature to 50°C. I think there is a lot of energy leaking out of your system somewhere. When you get the IR thermometer, see if you can point it at the solar thermal collector at night (bit hard I know). Be worth eliminating that part of it.

If it is a 3 kW element and it runs for 3 hours, that is 9 kWh. You must take very long showers, or the heat (the old word for energy) is going somewhere else. Re the above picture. Isn't it limited to 65°C now, what the reset is for?

You will, it is the crack cocaine of building technology

Pointing an IR thermometer all over the place (if it turns up tomorrow). will be very interesting. I frighten myself with mine sometimes. But as @newhome has an IT background, it won't be long until her place is wired up with environmental monitors (just share the code as my ESP2866 with a DHT22 and a BME280 decide to stop playing when I moved my router )

Yes you can, easily. Earl Grey always tastes like someone put washing up liquid in it.

Male workplace banter, which can creep over to quite vicious criticism, is often a way to highlight problems before they become too serious. Called 'keeping it real'. A lot of it depends on knowing your workmates well and outsiders (or management) are often excluded. I was an outsider on a job one time, and the chippy did not like something he thought I had done (was some badly fitted skirting I was trying to put right). He kept saying the same story 'about this bloke he knew' that had made the same mistake. I just used to stare at him while he repeated the story for the umpteenth time, then laugh. I was helping out a friend's son by doing whatever I could, he was paid to put things right. He never put anything right, but make one big mistake with me, thinking that I was a bit dumb. He was a bit shocked when I left early to deliver a lecture at the university I worked at. I generally find that idiotic humour gets me out of most problems. I have only had one problem in the last decade with a workmate. Young lad who was work shy, arrogant and a snowflake. He thought he knew a lot, when he was shown to be wrong, he would never accept it and tried to bluff his way out (bit like Trump). Eventually he said he was being bullied and refused to come in again. Thankfully the owner of the business, who worked with us, said he had not been bullied and was just a dick. I have seen workplace bullying and it is not pretty (I had to clear up the mess it left in the company afterwards), normal male work place banter is not bullying. Bullying is systematic and usually done by someone that has serious problems. Why, I do not know, spotting it and sorting it out is the tricky bit.

So have I missed anything tonight, apart from knowing that good tea can be made up there.

More Team America I think

I have had that. Then the bugger ended up owing me £1500. But to be honest, the guy was such a pain I was glad to see the back if him.

I had a Hoover or a Hotpoint, can't remember which. But the bearing was moulded into the plastic drum. If failed and there was no fix. The manufacturer had discontinued the model after about 18 months it was so unreliable. I got my money back (and 100 quid extra) from the retailer under the EU extended warrantee. Got a Bosch one now, not had any problems with it.

Lot more compelling that 'The Non-Adventures of Rollo'.

Did I miss anything

Had an E 300TE-24 as a company runaround. Could get most a steamroom or sauna in one.

I was thinking of having an early night, but this is getting as good as the real Apollo 13 mission . https://www.jsc.nasa.gov/history/mission_trans/AS13_CM.PDF

What we like to hear. I was moving a barrel of resin in the works Marina van. Hit the breaks and it slid forwards and up into the back the seats. Bloody things weighed 270kg. I drove the rest of the journey almost pinned to the steering wheel looking like Quasimodo's slightly more attractive younger brother.

Is there any chance that things have scaled up, do you have a proper water softener? And is there a chance that water is thermo-syphoning through the solar system and losing heat though that? I am thoroughly enjoying this thread and looking forward to a positive conclusion later.

No, as I have not had a TV for over 20 years. But Basil Fawlty said he would have a lie down, but changed his mind and said he would hit guests instead

Welcome Maria Everyone talks down to me as I am a pygmy

I ended up spending a night in Stoke Mandeville (Jimmy Saville was there at the time) with about 50 other people because of crop spraying. They have tightened up on the rules a lot in the last 30 odd years thankfully. No one ever talks of organophosphate sheep dip these days.

I live just off one of the roads in the UK that was highlighted in a recent report (odd as Cornwall has strong winds and 3000 miles of Atlantic upwind). They jumped on diesel cars being an issue (probably correctly) but failed to mention the high number of open fires in households (The Cornish are a traditional bunch and many still burn coal and Bristol slave traders (ask about tea and sugar)). Less than 50 yards from me is a house that frequently burns stuff that is so smokey that it can set off a number of smoke alarms (heard two yesterday). I am just waiting for @JSHarris to get his particulate monitor made so I can pinch his code (it better be Python). There was a report that I did not follow up about household cleaning products 'being as bad as 20 a day'. That could be interesting as the liabilities for the manufacturers would be huge if they knew about it.

I shall get back onto this later as I am a bit tied up at moment. I may not have explained myself very well when I said

I am not so sure that there is no problem. It is possibly true that in a very well built and managed building variations can be managed effectively. But in a chaotic building i.e. 4 kids and a wife, or maybe a scrapyard in the back garden automatic control could be advantageous. To give you an idea yesterday was sunny. I opened my back windows a crack to draw in some warm air from the front. This works well and saves heating the north east facing kitchen where I live. I forgot that I had done this as the wind was not too strong yesterday. Got home from work, turned the heating on as it was chilly. Had a shower, cup of tea and went to bed. Because my fan heater had tuned off at 21°C, I forgot to turn it off at the mains. This morning I had a lovely warm house. Only cost me 7 kWh. Now if I had MVHR with automatic balancing and control, it would have known that I had the windows open a crack as it would probably not have managed to balance itself properly and issued a warning, or just shut down the area totally. It is hard to quantify without creating a decent model, but at £1/day for that sort of mistake, it is not out of the question financially. I also think that MVHR could be split into separate units. One for the clean side i.e. bedrooms, livingrooms, halls and passageways, and another for the smelly side i.e. bathrooms, toilets and kitchens/utility rooms. Just like space heating and DHW should be split, I think there are gains to be had doing the same with MVHR as you can pick units to suit the different characteristics.
