Why did the heat pump break up with the air conditioner?

Because it was tired of all the hot air!

how much power would I need to divert to raise the temperature by 1C?

 

All of it.

Was the air conditioner a politician by any chance? 😜

Layman's explanation of how a PV Solar Panel works:

There are these two silicon atoms sitting on a roof in the sunshine.

A photon comes hurtling along at the speed of light and runs straight into them.

"Hey!" shouts one. "I've just lost an electron!"

"Are you sure?" asks the other.

"Yes. I'm positive!"

Save energy... recycle electrons!

Why did the electrician refuse to marry his girlfriend?

Because he wanted a current relationship, not a grounded one!

For those who didn't appreciate the point made by @editor above, can I point out that a grounded currant can easily be identified because it's still attached to the bush.

The alternative scenario has no reference to ground.
Here's such a circuit with direct currant:

And, for the benefit of doubt, this is alternating currant:

I'm afraid you are using the wrong colour berries, they need to be brown and blue. 😋

Hmm... It's the wrong time of year for blueberries.

I'll see what I can manage in autumn, which is when I'll also be getting ready to plant bulbs. 😋

A police officer in a hi-viz jacket turns up unexpectedly at the gates of heaven.

"I'm sorry," said the gate-keeper. "But I can't find your name on the list."

"Does it change things if I'd just saved someone's life?" asked the officer.

"Of course," replied the gate-keeper. "Tell me what happened."

"Well, I was in my patrol car parked on a motorway bridge, when I noticed a Climate-Change Protester run down the bank onto the carriageway. There was a lorry in the left lane, heading towards him. So I got out of my car, leapt onto the parapet and waved my arms above my head."

"Gosh!" exclaimed the gate-keeper. "Did he see you in time to avoid the protestor?"

"Oh yes," the officer responded. "At the last moment he swerved to the hard-shoulder, but his cab hit the bridge support and I got jolted off. The last thing I remember was falling and then being knocked sideways by the articulated trailer as it jack-knifed towards me."

"That's a very courageous act." said the gate-keeper. "You may step forward into Paradise."

...

A few moments later, another man wearing a hi-viz jacket turns up at the gates of heaven.

"I'm sorry," said the gate-keeper. "But I can't find your name on the list."

"To be honest," said the man, "I hadn't expected to be here either. But at least I died whilst saving someone else's life."

"And that makes all the difference," explained the gate-keeper. "How did it happen?"

"Well, I was driving my articulated lorry along the motorway," he started, "when I noticed a man standing on the edge of a bridge, waving his arms and about to jump."

"Oh, that's shocking!" gasped the gate-keeper. "What did you do?"

"I was going to pull into the centre lane, when I saw there was another idiot lying there who'd probably jumped just before him. So I flung the wheel the other way, and ploughed into the bridge support instead."

"I'm sorry to hear that," the gate-keeper replied. "But for your selfless sacrifice, you may step forward into Paradise."

...

A little while later, a third man arrives at heaven's gates. He's also wearing a hi-viz jacket, but it's torn to shreds and his hands are covered in tar.

"I'm sorry," said the gate-keeper. "But I can't find your name on the list. How did you die?"

"I was hit by a police officer!" protested the man.

"Really?" exclaimed the gate-keeper. "What were you doing wrong?"

"Nothing!" the man retorted angrily. "I'm a peaceful protestor. There I was, busy gluing myself to the motorway... "

The science of Climate Change demands neither compromise nor clairvoyance;

You won't gain anything by striking a happy medium...
... whoever she may be!

It's no wonder than energy matters are confusing.
Just look at the units of measurement:

We start with an EPC marked in points out of 100,
based on a SAP rating calculated in joules per square metre.

That gets translated to a heat-input requirement in kWh
which we convert to pounds to discover we can't afford it.

Radiator Sizing:

Anyone who has been owned by a cat or cats (we are merely their staff of course) will be aware that tracing pipe runs and locating the warmest spots in a room or corridor is best left as a job for felines - they will accomplish this task in a fraction of the time it would take you to locate your infra red camera or thermometer! We have a painting of one of our Siamese X cats that was created from a few photos back in the 70’s before we even had CH. The cat is sat on one of our home made rugs in front of the gas fire. Once we installed CH, the cats soon sussed out which radiators gave the best heat at various times of the day!

Modern ‘emitters’ are of course rated and I note they are given a ‘K’ type prefix; I suspect that the designers were cat lovers or had the good sense to consult with the feline community and that these newer designs generally have flat top faces, are noticeably wider and with the whole heat pump ‘always on’ heating schemes must have been designed with cats in mind! The only thing I don’t understand is the ‘K’ prefix when eny fule kno that Cat is spelt with a C.;-))) Regards, Toodles

Toodles, 76 years young and hoping to see 100 and make some ROI on my renewable energy investment!

This joke's on me.

It's often the case that I use a 3D printer to create a few components needed for an 'energy project'.

These can sometimes take hours to print, resulting in an overnight run... but using solar energy stored in off-grid batteries of course!

Occasionally my designs reveal weak points where there are flaws or separation of the printed layers.
These tend to get 'fixed' by welding together with an appropriate solvent.

Today I needed to apply a few drops of 'magic-glue' to items made from TPU (thermoplastic polyurethene) which is notoriously difficult to achieve.

I tried mixtures of solvents, both with and without a catalyst.

Eventually I succeeded.
I created a solvent mixture which could soften and melt together any plastic in my range.

So I carefully drew a few drops into my applicator syringe.... with the following inevitable result
