Hoping for some advice here, I have changed the immersion heater rod twice in the last six months, I have also changed the thermostat so I get hot water for a while but then it stops working What could be wrong, I have tried getting someone to look at it but they either dont deal with immersion heaters, or dont answer the phone. Thanks
All new immersion elements have a safety cut out thermostat AS WELL as the thermostat that you can adjust, the former is NOT adjustable. It maybe that the element is actually OK.
What rr is saying is that if you have the immersion heater thermostat set too high it will trip out the safety cutout on the thermostat. This then appears as though the heater or thermostat has failed, when all it needs is the safety cutout resetting. The purpose of the cutout is to prevent the water in the cylinder from boiling if the thermostat fails in the on position. Set the immersion thermostat at approx 60 degrees and you should not have any problems. BB
