Hello , i have a 145 litre water heater warmed by two emersion heaters but i think one of them may have failed , could you tell me how to test as to wether this is the case so i can identify which one , i guess this will include testing the stat on each one . thanks

It may be obvious to you........You have some experience of the subject.

unscrew the cables to one and put them in a connector block then see if the water gets warm..
if it does, repeat for the other one after re-connecting the first..

if the both get warm then they both work...

Isolate circuit from the mains then disconnect one of the wires feeding an element and use a continuity tester (bellset or lamp and battery) across the terminals of the element, if it rings /lights the element is ok, reconnect the wire and do the same for the other element.
A simple continuity tester to test Isolated circuits can be made easily with some wire a battery and bell or lamp. Wire between one terminal on the battery and connect to bell/lamp connect another wire to other side of bell or lamp this wire will connect to one side of element, connect wire from other battery terminal to other terminal of element.
