. Seem to have that multiple post problem again.

Noise is such a strange thing. I am parked up on Penzance Prom, it is a 20MPH zone. Got the car door open (to slow the (expletive deleted)ing cyclist on the footpath, the cycle path is less than 2 metres away, but separated by a wall for their safety, (expletive deleted)). Here is the noise levels.

28.4 https://noisetools.net/decibelcalculator

Half the real noise levels (the actual energy moving the air) or halve the number on the dB scale, which is logarithmic?

No he doesn't. What makes you think that? I have not seen a ToU tariff that has a cheap peak rate. It is the price differential times the usable hours that investment in batteries needs to be based on, not some arbitrary high or low price.

How so, it is a standard contract price with a major supplier. If you based your invest on just one price, that you choose to justify that investment, you are not looking at the long term/whole picture.

It could be like a mix tape.

My E7 is 27.5p/kWh day, and 11.08p/kWh night, with the daily theft of 70.1p/day (before VAT). When I am heating, I use an extra 10 kWh/day. That would mean I need a usable storage capacity of 12 kWh, which would be in the region of £6000 I suspect. £6k, at today's prices, would buy me 51,573 kWh, or 16 years price for all my energy usage.

Abd pays a premium for imported power the rest of the year, and that is before the cost of installing PV and batteries. (Energy suppliers can change the tariff regime as well)

Why not just run the ASHP during the cheaper times and store some of the thermal energy in the slab (assuming UFH) or in water. Chemical battery storage is still a way off being economical.

Welcome. I seem to remember passing through Yelland. Can't think why or when now.

Also makes it shrink back more, so as with most things, not as simple as first seems.

How much PV you thinking of fitting and what size will the wood burner be. I take it you are fully aware of the health risks of wood burners in the domestic setting?

So the paper pusher who makes sure a plane is refuel with the right type and amount is worth less than the guy who drives the truck to the right place. (expletive deleted)ing glad you don't work at an airport. It is the 'paper pusher' AKA middle management, that keep the country going.

Makes a lot more sense as we clean up our generation, but there should be a penalty for gas boilers. The main thing is to get the overall W.m-2.K-1 number as low as possible. More correctly would be to use W.m-2.ΔK-1 as that takes the users preferences and the house location into account.

I seem to remember that the Passivhaus standard for energy usage was based on primary energy i.e. how much coal burnt in the power station and not the delivered energy i.e. what your meter reads. Am I correct here?

They had smaller classes, so less social interaction, and what interaction there was, was just an echo chamber. (disclaimer, I went though the private school system, it does not guarantee success)

Only if the correct screws are used.

That is right. Used to be called Pizza ovens. (there is a load of shit spoken about kitchen equipment, easy to keep clean should be the overriding criteria)

Is that really the case, or a Daily Mail story? 2 minutes googling, it is a Daily Mail type story. https://www.hse.gov.uk/construction/faq-ppe.htm

The Health and Safety at Work Act (1974) is 50 years and 24 days old today. It has saved tens of thousands of serious injuries and countless lives.

Harvest it as a fuel.

I am all for that, especially the females.
