Hello, to forewarn you i'm a complete novice!
I have a gas back boiler which i use to heat the radiators and water for showers (a very old system possibly 20-25 yrs old). A few weeks ago the pilot light under the back boiler went off, so because it was the summer, i turned the gas off at my mains (to save money and to be extra safe).
I last used our electric switch to heat the hot water for my showers several weeks ago (the switch is a simple electric switch with a red light above it, to show when on or off), the light is off now. I also have a hot water tank in the loft, which i assume is connected to this switch. However i still have very hot water for the showers i take twice daily, even though their appears to be nothing heating it!
Can anyone suggest how this is possible?
I'm sorry i dont know the names or types of tanks, boilers etc.
Any suggestions would be greatly appreciated.
The shower is a mixer shower. Previously when the central heating has been switched off we have had no hot water (the shower was cold), whereas now we have hot water, with apparently nothing heating it.
The electric switch, i switched on to heat our water previously when the heating was off, is also 'off' ( i'm sure this is for the immersion heater).
I am worried how the water is being heated, like the immersion heater is stuck 'on' despite the switch being off.
