I would have though that changing the cylinder would be the cheapest, easiest and quickest thing to do. Or have I missed something.

That is how I got Firefighter and Evacuation. Here is the file. Datos-1º-trimestre-2021.xlsx -
How net zero works in reality
SteamyTea replied to oldkettle's topic in General Self Build & DIY Discussion
There are viable alternatives, mainly mass migration and rebuilding. As far as the UK is concerned, we have voted that one out. Regarding the costs, we know what large scale off shore wind, large scale solar and new nuclear cost, and we know that large, off shore, wind is also 40% more expensive than large, on shore wind. We have voted to not have large, on shore wind. So we know the costs of some alternatives, and even though they are lower, we coted against them. -

My Spanish is not good enough to look at the data tonight. Saw Firefighter and Evacuation. Not sure where they fit into the data. https://www.goronadelviento.es/en/statistical-information-and-data/ -

I don't know if anywhere has one of those old gas storage things that used to be in towns. Be fun to work out how much energy they could store. -

No you do not remember correctly. I am neither a fan or a critic. I do like the idea of compressed air storage, but in old salt caverns (they already exist), not bottles and cylinders. That opinion pieces is a bit confused and I don't have enough time to unpick it. But. Is the system performing as designed, or not performing as expected? That may seem a quirky question, but if I design a beam to take a 5 tonne load with only a 10mm deflection, then I put a 20 tonne load on it, has the beam fails because it has deflected 150mm, it is not comparing the same thing. -
Whatever flow rate gives you the optimal temperature difference between flow and return. Does the ASHP state that temperature difference?

Is on my 100 quid from Currys. I suppose I should be a bit more precise. Chart shows the percentage of time that draw was under 1 Wh. The point is though, you can banish most parasitic losses if you want to. It also shows that for my lifestyle, PV would not be that brilliant, except I could shift the E7 loads to the day (about 14 kWh over 5 hours).
-
Would you not just freeze the water in any pipes. I think it is illegal to run a turbine from a tap.
-
Fridge only draws occasionally. My phone is my router. I have purposely tried to reduce all the parasitic loads I can. And it has worked. We too often swap convenience for ludicrously high environmental damage. Just don't ask about the 600 miles extra I am driving every week at the moment, in an old diesel as well.

I use low power devices. Phone lasts me a couple of days, tablet a week. The only things that are permanent plugged in are radios and laptop, both low power devices, oh, and the energy monitor/weather monitor. I monitor my power usage and it is not unusual to have 50%, which amounts to several hours a day, when my house is drawing no power at all. It is all about management, not the number of sockets.
-
Need to know all the relevant wall floor, roof/ceiling (depends on roof construction), door and window areas, along with the associated U-Values. Then it is just addition and multiplication.
-
But you can import on the cheap (sometimes with a variable tariff). So just get some dedicated circuits i.e. washer/dryer, hot water, persecution chair, and wire them off the batteries.
-
Isn't that just down to storage, rather than power delivery though.

Can anyone recommend plant supplier

They grow like weeds here. One is even growing in the planter I temporarily (8 years ago) put some bamboo in. -
That is because you use Apple products. They are made for artist to do colouring in. Real people use a proper system.
-
The pipe spacing is about power delivery, not energy. The only problem with wider spacing would be if you had to run at a higher temperature, increasing losses to the ground, or required a faster slab recharge time i.e running on an E7 time window.
-
And the heat loss calculations for each room, along with the power of the heat source.

Torque requirements for power and lighting switches?

Should that be the other way around in Australia and South Africa.
