My immersion stat failed a few days ago, the heater just went and went so I had hot water, just it was very hot. So I switched the heater off and only had it on for short periods (20 mins-1 hr).
Today I replaced the stat, with one of those safety cut-out ones. £10 worth, so should be good as stats go. Anyway, despite having it set to maximum temperature the water was coming out luke warm at best. I checked and the wires were both live (i.e. the element was on).
So, I tried bypassing it by putting a chock-block in, just to check the thermostat wasn't at fault. It wasn't The water still comes out tepid.
The only thing I can think of is that the element burned out due to running at too high temperatures. Can't be scale, as that wouldn't be so sudden would it? The cylinder and heater are probably 19 years old, the age of the flat. The water is heated purely by immersion, no central heating here.
What do you guys think:
a) Burned out element
b) Scale, or
c) Something else?
As a matter of interest, how long does it usually take to heat a cylinder of water to 60 degrees? I am not sure what capacity the cylinder is or I would do the maths!
