As they are down here, even if living in a town. The sustainable aspect of personal transport is quite interesting. We are heading for an all AV future quite rapidly. So the pollution aspect is now rather moot. The congestion aspect is a bit harder, but as I point out to people, Cornwall really does not have a traffic problem. And we get 5 million visitors a year, that is 8.3 times the permanent population.

I had a Wimpey Bender once, it was alright. I miss the 70's, trying to work out what it would be called these days.

Ask @pocster, he knows a thing or two about cheap glazing.

Here is my fan. Been kicking around since March. Got a good bit of dust in it, but hardly a whiff when I switched it on. Had a few embers pop out, wish I had videoed it.

That is the external temperature. I like my house to be around 21°C. Monday was a pretty miserable day, grey and drizzle. Mean temp was 16.5°C, min of 2°C and max of 18°C. House was 18.5°C on average (was painting windows, so they were open most of the day). Min was 17°C and max was 20°C. Apart from the rain, Cornwall has a great climate. And the wind, mist, fog, cloud....

Not my experience. Sometime they smell if I drop sawdust down one in my shed.

Too right, fan heater costs a tenner to buy, even on day rate only about 25p/hour to run. Heats my kitchen up in less than 20 minutes from as cold as it gets. My experience is that, even when I leave the windows open at night, the house is 3°C warmer than outside. So the temperature difference is never quite as bad as it seems. Probably why I don't have to start heating my house until the mean temperature is below 10°C, and that is for when I am sitting and not when I am active. The only downside of fan heaters are the noise, can trip over them (an amazing amount of times in my experience) and if you get one that turns the fan off when it reaches temperature, you can forget to switch it off properly when going out.

So they will be offering even less help now.

check your areas. then multiply by temperature difference and U-value.

I went to school with a bloke that lived at Wingham Court. Now if my memory serves me well, his name was. Robert Conan Windham Lesley Maude. There may, or may not, be initials, other than mister, before his name now.

Just as bad down here, there is basically no wind today.

I looked at the weather forecast, it was good, got the scaffold tower up, pulled the guttering off to paint the fascia. Then this.

How difficult would it be to write a program that cycles though all the permutations, or is it combinations. Similar to what they already have. https://what3words.com/products/batch-converter/ Then just publish it online, and be damned.

Could use that module to charge 10 cells and run the pump from that. Or put a fat resistor on the wires and drop it direct into the hot tub.

Following on from what @Ed Davies said about needing a height difference to get theromsyphoning going, and rather than having a largish tank of water above the panel or tubes, could one fit a heat exchanger above them. Might even be possible to fit that in the loft and not use water as the transfer medium.

Looks like there is a joint in the felt, why did they not thread the cable though there?

Put it in a tin with an inlet pipe.

You could ask the DNO how large a PV installation could be fitted to 1 phase, they may allow more than the usual 16A limit. Then hang the appropriate loads off that circuit. Sound like an accountant wants to turn off the things (are these lasers) that make the company money.

Hard to imagine Winston Churchill thrutching on on, but easy to visulise Trump, trumping.

If it is yellow, let it mellow.

One of the reasons I like resistance heating, it is so simple to control.

PV can contribute to the running of the ASHP if timed right. What it cannot do is quickly switch on and off.

The SunAmp does not loose too much energy when it is charged, so the running costs are just a little less than parity i.e 1 kWh in, 1 kWh out. An ASHP runs above parity, usually somewhere between 2.5 and 4. So 1 kWh in, about 3 kWh out. The limiting factors of an ASHP is that they tend to get the high coefficient of performance at lower output temperatures. So limiting the output temperature to 40°C improves the CoP. This means that a larger storage cylinder is needed, a larger cylinder can mean larger losses, but good insulation will counteract this.

This is the wind for Newquay.
