immersion heater, water too hot !

[timmy toad]

hi all, my daughter has just moved into a rented house, it has no gas, for her hot water she has an electric immersion heater in the water cylinder, which is in the airing cupboard.

She says the water is too hot coming out of the taps, i looked all around the cylinder looking for a thermostat (like i have at home) but it hasnt got one, i take off the plastic cover on top of the immersion heater and all i can see are the terminals that connect it up to the electrical supply.

So, may i ask, where is the thermostat that will enable me to reduce the water temperature ?.

thanks in anticipation.

Usually it is next to the terminals under the cover, It will have a short link wire in it, that is soldered to one of the main terminals and also have the brown flex in one side.

Photos? If its just heated electrically, the thermostat may well be within the immersion casing, in which case it will have an adjustment under the cap.

By the way, if the heater is just running and running, it could well boil the header tank, which, if plastic, could burst sending hot water through the house. This is a bad thing. People have died. Dont use the heater if you suspect it of overheating the water.

Always best to switch it off before removing the cover.

The stats you see strapped round the side of the tank are usually for systems where a boiler heats the tank, water, with an immersion for back up only.
