Or kW even. If it is trying to deliver most of that 8 kW to satisfy the 3 to 4 kWh/day, it should only run for about half an hour in total.

Went to skool in Westcliff.

May be worth getting in touch with them, they used to be quite helpful, unless you wanted money off them. Your DNO should also have records of what is installed, and how. They should also know where the kill switch is, and may tell you to use it.

Yes, not many. What power is the heat pump?

To the grid. Is it MCS or some dodgy slave trader with fake work papers.

You may only be putting in a handful of kWhs, so may not enough time for the HP to get into its stride. Especially if the flow temp is high. Does it cycle rapidly when heating the water?

Do you mean unused from the batteries? It don't go anywhere it just stays as chemicals. Was it fitted through the MCS, they may be able to help, sucker.

Does the DHW CoP vary, month by month, during the non heating season? What are the flow and return temperatures when heating water? What size is the cylinder?

I a sure the Baxi boiler installer instructions will have a minimum volume requirements. If you can find that figure, go to the next size up to reduce short cycling of the boiler.

The simplicity of a simple switch. I understood how they worked when I was 3, and still understand how they work now. Purely out of interest, how many people here have had cataracts? Certainly made a difference on my view of lighting. I have a vision of a wise sage looking for water, using only rear stays from a bicycle.

The two main advantages that the Sunamp has is the compact size and the low thermal losses. Not sure if that is worth the extra money.

Heard about this on the news. Not just the elderly that get caught. https://www.bbc.co.uk/news/business-15984990

Probably.

I am quite clear with my customers, it is the postman that starts the gossip. I start gossip about the postman.

I have seen it a lot on insulated plasterboard. One place I had to decorate had every screw pop. They expected me to put it right. Told them it was up to the builder to sort it. Put me off the idea if ever using insulated plasterboard.

No mysteries in known physics. But words, in English, can be spelt the same and mean something different, and pronounced different and the they can be spelt different and pronounced the same. It is half the reason people disagree on things, the other half is they don't learn physics.

Not with physics you won't.

Ah. Now we really know what the problem is. Should have kept quiet and not replied, but that is something people from Devon just can't do. Or find a similar sounding village in Cornwall and claim the neighbour misheard. Actually any village will do, we don't pronounce the letters that are put in words.

Wish they would go back to the 70's, system boilers and a tank of hot water. Dead easy to understand. But even that gets complicated as they fit UVCs.

Re the earthing of modules. In the olden days some inverters needed an earth (transformer ones) , other did not (transformerless ones). But that could change between inverter manufacturers. Case of RTFM. Though I think generally, modules are not earthed at all.

I have seen many people move into the village I work in, only to be driven out again by the locals. So of the up country people deserve it, had one move in last year 'because immigrants had ruined the village they lived in'. I warned them with that attitude they would be driven out within 6 months, they were. The is no easy way to be accepted down my end of the county, some people are accepted, others are not, no rhyme or reason, just a small town mentality. If you aren't, and you will know within 12 months of moving in proper, you then have hard choices to make. Legal letters will get binned in my opinion. And we are as noisy as (expletive deleted), and what to know how much everything costs.

How do they monitor the power into and out of the SA?

Could be. Not going to worry about it house will be up for sale soon I think.
