That was my reaction too. I guess taking the wheel out would leave the potential for 0-9 confusion that the manufacturers wanted to avoid.

Here is what the video posted by @flameport shows. The left hand red digit tracks usage in units of kWh. From 0 to 1 units usage, the white units digit is in sync with the red digit. After 1 unit has been used, the white units digit stops for 1 unit's usage, so that at 3 units usage it...

So the left hand red digit tracks usage proportionately.

Ingenious, if a bit "counter" intuitive.

@Murdochcat It's higher than the estimates that I got by filling in a few wizards. These don't ask many questions and probably return a median value from a broad distribution - so much depends on what people are doing with the appliances. So yes, whether it's high or not is a moot point...

We do have high electricity usage - gas central heating, but electric cooker and shower. But that's not the whole story - we use less than 2 units a day on the shower. The high usage made me look closely at the meter, and wonder if it was recording correctly.

It does display digits 0 to 9 fully, but there is a twist. Transitions (0 to 1), (1 to 2), ..., (8 to 9) occur gradually with use, transition (9 to 0) is a jump immediately after 9 units are used. So it measures the use of 9 units, immediately displays 10 and keeps going. Then it goes (10 to...

Yes, usage will depend very much on the appliances, and we have an electric shower and cooker. So 4860 kWh is not outlandish when I monitor usage, but there is still a gap. That will be partly explained by the "restaurant receipt" effect where the total always seems to be more than the sum of...

Good question. Say the meter starts at xxx00. That right hand units digit gradually moves until it shows a 1 fully in the display - that is one unit consumed. Similarly xxx02 fully shown means two units consumed ... and xxx08 is fully shown when eight units have been consumed, and xxx09 is...

Our electricity usage seemed high - 4860 kWh per year for a 3 bedroom semi-detached house - so I started looking more closely at my meter. It's a Sangamo Weston S200.16. It has 5 white digits whose value is submitted as a reading, and two red digits to the right of these. The red digits might...

Did you find out the cause?

That makes a lot of sense, and I can see that it's a good policy. So far, I have asked a Gas Safe Registered engineer to look at the boiler but he didn't really get to the root of the problem (he replaced the spark electrode). He took about 2 hours, so I'm reluctant to go back to him. Are...

Could it be the pump?

A Baxi HE 50 Plus is locking out the ignition, but only during cold/humid spells. When the boiler is cold there is a sound of the gas igniting normally and the ignition light goes on for a few seconds, but after that it cuts out. So there is no problem in warm weather, and in cold weather...

Thanks all for the replies.
