True. We have been using them for years, and sorting errors is a problem, cheaper than handling cash and cheques these days though. But the cost is a normal cost of running a business, like PI insurance, pension and holiday costs. If a company thinks they are going to loose sales because of the financial cost of taking a deposit on a credit card, then run away from them, they obviously don't have a clue about running a business in the 21st centaury.

Do you know the efficiency losses from working it in a higher ambient temperature?

They start serious clipping of excess, then shut down. Why lofts where never a good place for them. Especially true if the inverter is undersized.

We have then in our larger fridges and freezers at work. Cheaper to buy a complete new unit than repair. They are really just the working part of a fridge, nothing special about the. At least you did not spend £8k on it.

As they generate thermal energy as part of normal operations, use that energy. So somewhere that can vent to the house when it is cold, or vent to cooler external air when hot. Real shame they are not liquid cooled, that would make life a doddle.

Isn't that what it is all about. Assume they can/will go out if business and mitigate your personal risk i.e. pay part in credit card. If I was a manufacture or installer, I would set that up as payment terms, then use it as a selling point.

Count the LED pulses on the meters. Posted up details on how to do it.

Good man, it is what I did.

Hope he has assets in his name you can claim against if it goes wrong.

How did my wingding text get to normal readable text.

Tell them to hunt me down. Then I can use the arguement about selling knowledge.

I am sure a script could be written that auto corrects most of them. Run it through the FMG's new friend, ChatGPT, and see what nonsense comes out.

How many small loads get switched on and off daily? The controller probably cannot cope with them. Much of the time my base load, which is a bit of a nonsense term, is zero, which in reality is just the meter not coping with a 3W like lightbulb, untill it has been on 20 minutes. Get rid of most of the parasitic loads, then work on the heavy stuff.

That should push his price up, not down surely. https://en.wikipedia.org/wiki/Learning_curve

Seems the sensible approach. One I am taking with having to move my Mother at, slightly extended, short notice. In this weeks comic, there is an article about procrastination, I am still thinking about whether I should read it or not. I would post it up, but it will only get run though ChatGPT and loose its true meaning, so will not bother. Actually, (expletive deleted) it, shall just run it though wingdings. Mind Thief of time: How to stop procrastinating and start doing Procrastination can steal hours of our time, but the latest research has some answers about how to reduce it, finds David Robson in his new 60-second psychology column By David Robson 12 April 2023 Drazen Zigic/Shutterstock PROCRASTINATION, we are often told, is the thief of time. When I notice my days slipping away in some unfulfilling activity, I cant help but feel a sense of loss for all I might have achieved and guilt for failing to keep that burglar at bay. According to the psychological research, our self-admonishment may only make it harder to break the habit, because procrastination is often a way of coping with stress and self-criticism. If I feel anxious about writing a new chapter of my book, for example, I may choose to hide my head in the sands of social media rather than facing the feared reality of a bad first draft. This is counterproductive, since the lost time will only make poorer performance more likely, but it provides short-term relief from the anxiety I am facing. Studies show that the higher our fear of failure, the more likely we are to procrastinate. If we then beat ourselves up, it is only going to raise our levels of stress and anxiety, which may cause us to look for more relief in temporary distractions disrupting our next task, too. The result is a vicious cycle of self-sabotage. For this reason, psychologists suggest that practising greater self-compassion may be one way of reducing procrastination. Imagine you are talking to a friend in a similar situation. What kind words of encouragement would you use? This exercise reduces self-criticism and people who practise it tend to find it easier to meet challenging goals. Engaging in self-compassionate thinking increased the time students spent studying after having previously failed an exam, for example. You might also consider employing a little strategic indulgence a concept I recently discovered at the Society for Personality and Social Psychology conference in Atlanta, Georgia. Put simply, this means including procrastination as part of your daily schedule. One of my main sources of time-wasting is funny YouTube videos, for instance, so I might decide to enjoy those for 10 minutes at 11am, before returning to writing. With strategic indulgence, we can still experience the short-term mood boost we crave. But since it is a deliberate decision, we dont have the feelings of failure that come with our spontaneous procrastination, so we are then less likely to descend into that spiral of unproductivity. It seems to work. At the conference, Lile Jia at the National University of Singapore revealed early research showing that students who work distractions into their schedule tend to maintain higher motivation and make better progress towards their goals, with less stress. In todays hustle culture, it is reassuring to see research that celebrates self-compassion and self-indulgence. The thief of time may be an inevitable guest, but, with the right mindset, we can ensure its visits are short.

Yes, k (kilo, for thousand), W (watt, for joule, the unit for energy, divided by s, the unit of time) and h (hour, which is 3600 seconds). So take your batteries at 10.8 kWh, that is 10,800 J.s-1.3600 s-1 The s-1 cancel out, so 38,880,000 or 38.88 MJ. Life would be so easy if we discussed energy in joules.

When buildhub was being set up, I was asked to join in (with some funding, I declined for a few reasons, only one I made public). Things then moved on and the layout of the website was discussed. I suggested that it should follow the form of a person building a house. So Search, Suitability, Legal aspect of buying a plot/property, then moving on to Construction Types of Foundation, Energy Usage, Ease of Construction. Finally all the Nice Things start, like Windows, Roofs, Bathrooms and Kitchens. It is only by constantly looping back and reviewing that the best compromises are reached. It did not happen that way and we constantly read about people that have problems with the Nice Things, often before the plot is secured, or foundation built.

The product of Kelvin, angular momentum and time. And interesting derived SI unit.

It does. With UFH you need to have a lot of insulation below it, or you are just heating up the earth. Don't confuse temperature with power, or energy, they are all different. UFH really needs to work at the lowest temperature possible to deliver the power needed. 40⁰C is really the upper limit, you would not want to stand, bare footed on that for too long.

Bowie did a song about it in '73

Getting back to the bird boxes. As nature does not follow the English Legal System about ownership of property, what is to stop bats moving in, and if they did, could that cause problems if you wanted to do a bit more work on the property? I closed off my extractor fan outlet this year this a proper vent cover, last 4 years I have had the house martins move in. Happy Hour, I don't think so, but it did only take a little time.

You should run it though ChatGPT o get an alternative meaning. It would condense this whole thread down to 'give me my money or blocks'.

Brilliant. You have already done a good write up about using woodcrete ICFs, which should have been enough to put everyone off, but then, having just had a long conversations, again, again, again, about my coffee drinking mate's Mother's heating (he is still convinced that a more expensive, oil filled, resistance heater is going to be cheaper to run than just a cheap panel resistance heater), the old joke about the difference between a drum machine and a lead guitarist comes to mind. With a drum machine, you only have to punch the tune in once.
