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

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

But at least the applicator is easy to take apart and clean now. 😋 

Q. How many MCS staff does it take to change a light bulb?

A. Two.

One to instruct an approved installer how to screw it up,

and one to issue a certificate of compliance.

and none to do anything about it afterwards.

My heat pump installer was so impressed with the energy saving capabilities of the new generation circulating pump he installed 2 of them for me. He said “That-way you would be saving twice as much…..” I laughed so much I lost my headder….

Im here all week….

And do we remember the inventor, Harold Bate?

In the late 1960's he developed a system to create methane from chicken poop, on which he ran his car, a small lorry and heated his house in Mid-Devon.

Oh, how we laughed...

Excuse me, I've got to go out and buy some more chickens.
