Where is the kWh price heading in 2022?
SteamyTea replied to epsilonGreedy's topic in General Self Build & DIY Discussion
What you suggesting, converting 1 Megaton of nuclear energy to 1,162,222 MWh of gas. -
That is badly spelt power. It is kWh of storage.

Odds are that the outraged come with a storm from an unexpected direction. Those trees will take 30 years to grow back and be a problem. It is not like flooding. That tends to be a problem after a prolonged dry spell.

Why it is called Pico Generation or Energy Scavenging.

Maximum demand greater than 100amp single phase ukpn

Sod how large the roof is, or how wet. It is less than a kWh. My car does 1.5 miles to the kWh. Be easier to park closer to 100 metres away from the house i.e. in the road I live in rather than the parking around the back.

I bet it isn't. It may be on imported energy, home grown is still energy.

Self installing solar modules and inverter
SteamyTea replied to Radian's topic in Photovoltaics (PV)
That is more the nature of the PV installer industry than any sizable discount you may get. Why tie up a few thousand in cash when you may not want to install in a month. Saw all this happen when FiTs dropped from the stupidly generous 45p down to the generous 22p or whatever it was a decade ago. -
The whole of yesterday I used 3 kWh, for absolutely everything, that is a power draw of 0.125 kW.

ASHP for a single 100m UFH loop?
SteamyTea replied to Radian's topic in Air Source Heat Pumps (ASHP)
Here we go, with thanks to @Trw144 https://www.wolseley.co.uk/product/vaillant-arotherm-plus-air-source-heat-pump-35kw/ -
ASHP for a single 100m UFH loop?
SteamyTea replied to Radian's topic in Air Source Heat Pumps (ASHP)
Yes, but as it will only run for a short time, frosting may not be an issue. When I get home i shall see if I can find the little pump someone suggested. When I looked at the physical size, it was the same as the 5 kW one. And probably more expensive. -
ASHP for a single 100m UFH loop?
SteamyTea replied to Radian's topic in Air Source Heat Pumps (ASHP)
I found (well someone else did) a 3.6 kW (may have been a 3.8) ASHP. A bit of searching on here should find it. All I need is a very small ASHP and keep wondering if a very basic swimming pool one, connected to the heating via a decent size buffer, will do the job. Not as if it will run for very long. -
This 1956 paper is easier reading. It explains why we don't use lightening to charge the national grid. The Electrification of Individual Cloud Droplets.pdf

From 1926. So a reality check is needed. If a few drops of water could produce a usable amount of power, think of all the metal things, especially aluminium, that is insulated from the ground, say a boat on a trailer. Touching it would hurt. As this is not a new concept, with the physics known about for over 100 years, if it was viable, we would be doing it. rspa_1926.0108.pdf

Always compare any extra you have to pay for that with a small (2 kW) portable generator and an extension lead.

All this assumption that bills are going to keep drastically rising is worrying. Now I don't know what any individual pays, or what 'deal' they are on, but over the recent decades, household energy bills have averaged about 5% of household income. If there is an expectation that the fraction will become 15%, then the government will step in (again). There is also transport fuel costs to take into account. These have gone up. If an ordinary household uses 1000 litres a year (oil companies used to work on 1 tonne a year per car), then that is approximately £500 extra year. It is just a matter of how the government steps in (individual allowances, or state aid to the producers or retailers) and when. Still, we have paid the $400m to Iran by the looks of it. -
Possibly caused by static charge, so just electrify the roof. https://physics.nyu.edu/grierlab/charge6c/

Just get a third meter that switches on when cooling.

It was alright till 10:30 AM.

Here is the data for Niton. Did not rain much on Jan 1st. https://www.wunderground.com/dashboard/pws/IENGLAND232/table/2022-01-1/2022-01-1/daily

What you do is drill a large diameter hole down to sea level. Then, when the waves hit the bottom of the hole, the air in the tube is compressed, this then runs a turbine at the top of the hole. The Wells turbine is the type to use as it spins the same way regardless of air direction.

Wave power would be better.

I used to use a company called London Toughened Glass. The sheets used to pass though a tunnel with gas burners in it. There was nothing done to recover the waste heat in the building.

This going to be fun. As for rainfall, what is your location, nearest town North East of you should give a fairly good indication. Statcoulomb is a good word. https://en.m.wikipedia.org/wiki/Statcoulomb

The Economics of our SunAmps
SteamyTea commented on TerryE's blog entry in The House at the Bottom of the Garden
Reputation points are one way. But then, for a laugh, I got @pocster to keep voting for me, then I returned the favour, once. This is why it has been suggested that with things that require calculation i.e. thermal losses, electrical power, seasonal heating loads, some basic calculators are created. Nothing fancy, just basics, with an explanation of the workings. Then, when we get asked for the umpteenth time about how much insulation to put under an UFH system, we just point the person to the calculator, maybe a permanent link to a page, somewhere near the top, like the banner. When I suggested this, I was told, not by you, but another, that if it was so simple, why don't I do it. So I did and posted up a link to a simple example. Then I went to Canada and forgot all about it. Think I may still have a folder if HTML5 calculators in my PC.
