I'm not from the UK and am used to water being heated on-demand by a gas heater.
Having recently moved to London, the flat has electrical heating and I cannot figure out how I'm supposed to set this electric boiler system.
Here's some pictures to get an idea of what's there:

The control unit has a switch with positions Off and Timed. There is also a boiler power switch labelled Immersion.
The Immersion switch seems to turn the boiler on, as it starts making water noise when turned on and five minutes later I can get some hot water on the tap.
With the Immersion switch On, changing anything else on the Control Unit doesn't seem to have any effect. Again, when the Immersion switch is Off, there's no hot water, regardless of the Control Unit.
On the top side of the boiler, to the left of the Important label, is a valve which is itself labelled as T&P valve and the label next to it refers to a Temperature and Pressure release valve.
When I turn on the Immersion switch, water starts heating, but about 10 minutes later, water comes out of this T&P valve. It's not dripping, it's actually running, I can't estimate the debit, but it's probably like a half-on tap, which to me seems like a lot.
The Important label says: If the T&P valve is dripping (not running) to 1) Turn off mains water, 2) Open a tap, 3) Hold the valve open until it stops making noise, 4) Turn off tap and mains water back on.
I've tried turning on the Immersion switch, waiting 10 minutes, water would come out of the T&P valve and then I've turned on the shower. The shower was warm, but not boiling hot, and the water turned to completely cold in about 3 minutes. After this point, the T&P valve still had water running out.
After I turn off the Immersion switch, the valve will stop in a few minutes.
Does anyone know how this thing is supposed to work?
