Would tend to, but I suspect that it is also metering the electrical resistance heater that kicks in for the legionella cycle, and when the heat pump cannot cope. Have you had your system 'tuned' or us it at factory defaults?

The colour may change in a few days time. Or might not. Did you pay with a credit card?

You can go and build @Omnibuswoman's place. And @BotusBuild

I read on. So many questions to ask, where is the free version of codes/regs. The arithmetic looks manageable, but the devil is in the detail.

Or they think, by some unproven magic, that it will harm them. I have a power line pole outside my house. Luckily it distracts from the pretty awful house below.

Um I wonder if they read my paper on it. Maybe I should take a quick look at what they wrote.

Not in the cupboard under yours stairs though. We need to pay for a certificate to have a DHW cylinder running at 3 bar, just imaging what a fast spinning device with 5 kWh of energy will need. It is already used for grid balancing, if you go to WPD substation near Redruth, you can hear them humming sometimes. https://botlanta.org/converters/dale-calc/flywheel.html

Life. Wind and solar have been the cheapest new generation source for a few years now. Just a case of deploying it.

I looked into it as well. The energy density is not that great, even if the power density is good. And the thought of having a washing machine sized bit of kit with a flywheel, rotating at 20,000 RPM, is a little worrying. Williams Engineering used one in their cars in 2009, when KERS first came along. They sold it to GKN back in 2014. Think there may be a system on Eigg, not sure if it is running.

How do you distinguish between good quality and good design? They are not the same thing at all.

Thanks

Yes, it is what I have a huge pampas grass out front. Evan better than my neighbours bush.

Cheap Posh Hertfordshire's Finest. Except for Vinnie Jones.

I was taught that fuses are designed to have a life, the higher the current, the shorter the life. Was not a straight line but an exponential curve. This is why, a low amp fuse i.e. may suddenly blow after years of sterling service for no apparent reason. Also why we have quick blow fuses.

There are not any, unless it toppled over when you are underneath.

No, I have not had that experience. Oh hang on. I had bad cataracts just over a decade ago. Then, after the replacements, I had some quite bad side affects. Now I am trying to remember the last job I did when I worked in London, oh yes, I worked for the RNIB. A previous job, was for a lighting manufacturing company. Get proper advice, not from a lampshade seller, or tech 'disrupter'. You can have that from any amperage outlet. What you are talking about is the light controllers and the diffusers, (expletive deleted) all to do with the wall socket or where the switch is. Generally yes. Was easy when I lived in the tropics, pain in the arse this far north. I still find it odd that there is fairly good light at gone 10 PM in the summer.

How about a link to the product or future reference.

My view is that too many people, put too much emphasis on lighting. When I am out and about, I am quite happy with the light that the sun produces, and that is just, in effect, a large pendant light. Sometimes it is obscured by cloud, which is the same as putting a lamp shade on it.

We are constantly selling shit to upcountry folk. Charge an extra fiver by just putting the word Cornish in the description. What size is the cable? Can't you just wire in a 13A double, like it should have been in the first place. Wiring in 5 A sockets is like wanting to get a 1950s childhood illness "because what don't kill you, will make you stronger". Or driving an old Landrover.

How irritating.

Welcome Have you read the comments on here about developer new builds? Easier to have look at other places. Or make a ridiculously low offer, then move it on.

Then the CoP is creditable.

Can't really say without seeing real world data. But a sales person would tell you none, 10% or 30% depending on what you want to hear. I think you should go for it, then tell us all how well, or not, it works. By it, and a proper one. Then flog he proper one after you have the VAT back. Or sell the duff one.

While I agree that having modulation on the compressor is a good thing, for basic heating, for most of the time, how much of a difference will it make. Fitting an oversize buffer tank would allow for storage of higher than optimum temperature water, while still limiting the number of cycles.

No idea what thickness, but my shelves hang off the plasterboard only. But this may be worth a read:
