HELP NEEDED Immersion Boiler Dripping issues and concerns

John, 99 percent of the flats I come across are single supply only. This is central London and docklands though, small flats probably wouldn't benefit as much from e7.
 
Once you are on the right tariff, it is, of course, cheaper to heat it to full at the overnight cheap rate, then to stop. It is probably more than big enough to supply your hot water all day, but if necessary you can ocasionally top it up with the upper element

I am shocked that a flat with a big cylinder, and electric UFH, was not already on an E7-type tariff with overnight cheap rate.

Indeed John and what's scaring me is the fact that it consume 3kwh per hour for every hour last night I had it on. Is that alot btw?

By the looks of it I seems to be utilising 20 kwh in a day ? And my heating is switched offf which is under floor heating !! Is that alot ? I think there is a fault with the meter !!!
 
3kW is what an imersion heater uses, until the cylinder is hot and the thermostat clicks off.

It is also what a typical electric heater, washing machine, tumble-drier or kettle uses, so if you run any one of these for an hour, it will use 3kWh.
Look at your bill, you are probably paying about 14p per kWh

Lighting, TV etc use next to nothing, especially if you have energy-saving lamps.

I actually have g10 halogens which since the bill I have switched off and brought lamps with energy saver bulbs!!! I have a feeling that the temperature sensor may be gone. But I highlighted this to the engineer and he didn't seem to think that was the case. I had it on for 4 hours last night and this is what it showed in the meter. Should I try tonight for 6 hours?
 
buy a thermometer and see what the temperature is.

as long as it is not dripping and you have no taps running it wil switch off when hot.
