understanding storage heaters

Going back to the water heater we have a switch like that which if it is switched on will heat the water all day and all night when required, we leave that switch off as we have a timer above it which just heats the water over night on economy 7, if he is heating the water 24/7 that could explain the high usage during the day, have a look around and see if there is a timer anywhere for the water, we use to have a control panel in the kitchen but then changed it to an independant timer once we got a new water tank installed but for whatever reason they still left that switch.

Could the day and night meter readings be swapped? Take both readings in the morning and again in the evening. Only one should have changed.

The rate shown by the steady state display is likely to be the rate in use at that time.

i think they are the right way round in the last 3 days the day one has gone up by 49, and the night one has gone up by 10.

That may well be true, but you still need to establish which rate is displayed during the day, when it changes over and when it changes back again.

If the difference is 7 hours that's OK, if it's 9 you probably have two hours at day rate sandwiched in.

Have you seen the actual bill ?    Are your readings consistent with it ?.


I think this is a R1/R2 reversal-

You could try winding on the timeswitches by 12 hours -  and tweak the 2am-3am setting to 6 am - 7am at the same time.

Interested to know what the Hospital Property is  -  is there a tubular heater in the shed ?

At the moment - you aren't isolating day / night consumption by taking readings over a few days or weeks.

A simple test - two readings several hours apart in day time - what we expect the meter peak rate / day rate window - should make it obvious which register reading is incrementing mid day.

Can you ask brother to do that.

And see whether R1 or R2 clocked up - allow time for 1-2 kWh to be sure.  Thats not a lot - cook a meal, electric shower, do a load of washing - just pretty normal use if long enough - only one of two registers should have incremented.

A more thorough check would be to check R, the  R1 and R2 registers - and the 100A led status (which should be accroding to a post found elsewhere be on during the off peak period when ALCS e7 circuit power on) - at start and stop of peak and off peak periods.  But at least one of those is likely to be at an anti-social hour on many an E7.

[In the 4 reading photos the R seems to match the bill difference R2 (both in the 60,000s) - but I am only assuming that might switch to the current live register - and the 100A LED is off - assuming photo taken in day period and the LED works as expected) ]

PS 

Where did your brother get the idea of setting all the input powers to 6 - and again how hot was the flat - given Feb and parts of Mar fairly mild in many parts of UK ?
