That will be 0.021 Wh then. 0.5 kWh a day. So somewhere between 3.5p and 17p per day. Or £13 to £62 a year.

I did from my big standard 1987 era E7 200lt cylinder. About 20p a day when heated to 65⁰C. Lot less now it is at 45⁰Cish, and I use most of it just after it has reached max T.

I am not allowed to write it anymore. Last one I printed out said. "(expletive deleted) off back upcountry". Did stick it on the door of another restaurant.

Were. Only as good as the last job.

So @pocster's walk on glazing did find a home.

How many miles a day do they travel, 2?

Something that had been happening, since he was a lad

The doggerel was bad, which made him sad.

Seem to effect halve my customers tonight. (expletive deleted)ing morons, can't read off a menu.

Don't know. Miss him though.

Is he still reading the posts?

Grip Strength

A good counter example, a rubbish statement, backed up by another one. You got to get a grip on it.

That is exactly my point. I do not know. I understand not using any imported energy, and I can assume that consumption is 10 kWh, but is that a day, a week, or for the whole month.

Thiyse figured are meaningless, or wrong. What is the time period, second (in the case ift kW) or month (in the case of kWh). 50%+ if the time I have no consumption, measured at the Wh (3600J) level.

So you have fallen for the dodgy carbon accounting methods used for all biofuels. Oh dear, there is little hope left.

A few of us are mucking about with wires and code, hoping to make a cheap and accurate energy meter. May be worth spending 25 quid and knocking one up. https://forum.buildhub.org.uk/blogs/entry/946-the-energy-meter-experiment/page/2/?tab=comments#comment-5986

There is a similar problem with composite plastics. Many a time I have heard 'we added loads of hardener and it went off (hardened) just fine'. This is a real problem when doing flat roofs as the pigments change the depth that UV radiation can penetrate. So you can end up with a partially cured base layer, with excess liquid or gaseous styrene monomer trapped in it, but a fully cured top layer.

Yes, been telling people this for decades. Few listen @Joe-90 Get a proper heat loss calculation done, then see what your options really are. General point, who thinks far infra-red heating will enter the conversation here?

They are not brave enough to take on the independent roasters down here. Wish they were, when I see a 'Cornish Coffee' sign outside cafe, I walk away fast.

If I was there, first trips would be to Fort William or Inverness. They seem to be the closest Costa Coffees.

Can you explain a bit more, intrigued how you get a 15° twist out of a plank with a plainer.

How do you know they are all working optimally?

Right. They need to update it.
