Is it possible for PV diverting the opposite way round
SteamyTea replied to Gone West's topic in Photovoltaics (PV)
Yes, but what I think you are asking for is a ready made device that does it 'out of the box'. That probably does not exist because of the way immersion heaters work and the varying output from PV -

I’m confused about ubiquiti
SteamyTea replied to Adsibob's topic in Networks, AV, Security & Automation
"I’m confused about ubiquiti" I am still confused as how to pronounce it. Is it Why Fie, or whiffy. -
How does your garden grow?

Did I leave my webcam in again. Really should cover it over to stop the peeping toms and slutty thongs. -
Think it says what you always knew. I think motorised vehicles and sack barrows/pallet trucks are different. Gets a bit grey when you think about a push bike (almost certainly allowed) and a motorbike (almost certainly not allowed), so an electric bicycle or scooter is on the cusp of being allowed, as long as it is manually moved. So this brings in a mini digger. Some are tiny and can be pushed though standard doorways, so they should be allowed, while others can only realistically be driven, so not allowed. Just make sure all your contractors know which house to park in front off. 37 years ago, my neighbour got fed up with a local company van always parked outside her house, so called the company. There response was; "Strange that as we built him a garage to park the van in" Two days later, after a visit to the garage, which was full of company goods, the guy was signing on and waiting to be prosecuted for theft.

Comes down to sizing an ASHP correctly, just as you would with any heating system. Then it is down to installation costs and running costs. The first part has to be done first, then the other parts can be established. Limecrete is not really breathable like an airbrick, it is more a case of letting moisture wick though to the outside, where it evaporates. Depending on the mix, it is not inherently different from concrete mixes. Getting the kg.s-1.m2.kPa-1 numbers is challenging though, why there is so much 'mystic' around lime. It is a short hop from the above units to kg⋅m2⋅s−2 which is a unit of energy, and as we know, if you increase energy levels in a solid, the temperature rises. A pascal is kg⋅m−1⋅s−2

As PV is generally fitted to South facing roofs, at about 35⁰ angle. June 21 is not the best day just because it has the longest (or second longest) hours of daylight. An E-S-W array would be impressive, especially if E and W elevations were angularly optimised.

So £1300 per kWp installed. Assuming you generate 6.5 MWh/year from that for the next decade. That is 16p/kWh A lot depends on how much of that you can use. If you self use half of that, then it is 32p/kWh. About what we pay to buy it in.

Can you use a pressure vessel to store the water. It may be called an accumulator. Usually used to flatten out pressure fluctuations when load is greater than inflow can cope with.

Reducing Energy Bills - How goes it?

Down here, 'local' can take a dislike to people. I have seen up country folk driven out of towns because of constant narking and rumours. All totally unfounded. Then there is the use of social media, and as one old loony does, posts up diatribes on lampposts about non specific individuals who may, or may not, have done anything wrong, or intend to do anything wrong. Very effective. Onan hag oll

SteamyTea replied to Ferdinand's topic in General Self Build & DIY Discussion
It probably uses less energy, but that may be more to do with the overall losses of the actual oven, rather than the amount of energy that the food takes to warm. -
Reducing Energy Bills - How goes it?
SteamyTea replied to Ferdinand's topic in General Self Build & DIY Discussion
Some of it will depend on what you want your food to look, and taste, like after heating. A microwave is very good for heating/reheating, not so good for the Maillard reaction, which is what can cause complex flavours to emerge. Try doing cheese on toast to see what can go wrong. As an aside, microwaves do not cook from the inside, that is just a myth. -
Can you redo those calculations for people who do not have access to the gas network?

Bit in radio about air fryers. Seems they can cook small amounts of food, with smaller amounts of energy. https://www.bbc.co.uk/sounds/play/m0018hjr -
The roofs, the windows and the solar PV array

Not pollen that makes your nose run, and your arse smell. It's because you are built upside down. -

How big is your array, 2 hectares. Think you mean MWh.

Reducing Energy Bills - How goes it?
SteamyTea replied to Ferdinand's topic in General Self Build & DIY Discussion
Because we know that, generation is significantly reduced. It is reduced, in part, to keep the return on investment high. Having seen the price of my E7 night rate go from a little over a third of the day rate to over half the day rate, and the biggest change in the last two years, I would not be investing in the long term reliability of twin tariffs.
