The judge found the insulation foam product itself is “essentially safe” if properly applied with the proper safeguards.

Got a link to that? My neighbour has holiday home in France.

On Radio4 they were talking about Macron and Merkel and the fishing rights and accidentally called him President Mackerel.

Those with holiday home only allowed to use them for 90 days at a time.. Daily Mail: Half a million Brits can only stay in their holiday homes for three months at a time from 2021. https://www.dailymail.co.uk/news/article-9019917/Half-million-Brits-stay-holiday-homes-three-months-time-2021.html

It looks like some sort of anti short cycling feature. It monitors actual flow temperature and target flow temperature and treates the difference as an "energy deficit" that it counts up. So if the difference was say 5C for 3 mins that would be 15 units of deficit. When that deficit reaches the level set in the Energy Integral parameter it turns the heat pump on. When the deficit has been eliminated it turns it off. I've made up these numbers, I've no idea what value the Energy Integral should be set to.

On page 10 it says the units of Energy Integral are degrees. So its not energy consumption. See para 3.6 on page 15.

An integral is typically a total over a period of period of time. So an "energy integral" could just be your total energy use over a period (day/week/year) etc. On the other hand it could be marketing BS. If there are any graphs involved an integral is usually the area under the curve.

PS Duct should be insulated anyway.

Condensation is less likely at higher temperatures. So I would expect proximity to ufh pipes to make condensation in mhrv duct less likely.

Diagram 44 Page 67 of part j shows that the opening part must be 300mm vertically or 1m horizontally AND shows that a non opening part of the window can be nearer.

How fast/slow is the pulsing? I've found some clusters of LEDs flicker badly when dimmed even with the right dimmer. This is particularly noticeable when viewed out of the corner of your eye because the edges of the eye evolved to see moving predators. Im talking about 50Hz flickering here. Some LED bulbs can flash or pulse more slowly when dimmed below some percentage. Typically 20-25% not usually as high as 50%. I guess this is more like 1 to 5Hz flashing rather than flickering. I believe there are some dimmers that can be programmed to switch off when dimmed below a programmable value. Perhaps check the data sheet for your led lights to see how low they say they can be dimmed.

If the ups/server and cameras are powered by different RCD I wonder if some kind of loop is formed that can trip the RCD? I know it definitly shouldn't do but it just feels like worth seeing if it trips with everything disconnected from the server?

I was asking because some people propose building caravans and houses from containers thinking thats a way of avoiding the need for planning permission.

The inverter and other losses might reduce that by 50%? Call it 100 WH ? Draws 10 to 40W. Depends on disc activity. Top end of that range if recording video? How are the cameras powered? Also off the UPS via POE hub? So I would predict somewhere between 2 and 10 hours at most.

+1 Would help to know more about why you want to build a "caravan"?

Ah I think the hole for the door knob will be wrong height if you turn it upside down.

Can you turn it upside down? Does that work or do I need another coffee? Failing that most good glass merchants can make shower doors to fit any opening you have at a price. Measure carefully though.

I used switches to detect the doors being opened and turn on lights. Helps remind people to shut then.

Seems that's because the mhra are doing a rolling review.

Last I heard Moderna one of the other vaccine makers had applied to US and EU regulators for approval but NOT the UK.

If you can afford the time then I think I would also go for a knock down and rebuild. Your situation is somewhat unique in that they are already allowing the external appearance to be significantly changed by removing the cladding. I think the key to a new application would be to argue the end result would be identical to the conversion already permitted. So avoid any temptation to change the design at the same time. Perhaps even use the same drawings. Ideally find an appeal that allowed a similar case and submit it with the application. I'd like to think the planners could turn this around in 8 weeks but depends how pedantic they are.

And..
