Conclusion: Had to get a Megaflo engineer in. Both thermostats were faulty and the immersion elements were heavily scaled. Once they were de-scaled they worked properly and no more over-heating of the wiring. Incidentally the cables to the switches were replaced with silicon cabling which...

There is 240 volts at the immersion but it doesn't seem to be working. The thermostat is the new one, and the button is in. I couldn't wait any longer for the element to heat as the switch was very hot after just half an hour! The end of the live cable at the thermostat end was heat damaged...

HELP!!! Problems still... The supplier only sent one thermostat instead of two. I fitted it to the lower immersion. Water did not heat. I noticed that the wiring from the fused switch to the immersion was warm. Half an hour later the switch was almost too hot to touch. I checked the wiring...

Thanks to everyone for helpful advice. Update - I finally got to check the system. There is power at the switch and to both controllers. The thermal cut out had popped on the top thermostat. I pushed it in and lowered the thermostat a bit as suggested. The body of the thermostat got hot, as did...

Thanks for those explanations. I'll be investigating the problem next week and will report back.

Many thanks for that. I'll check those things first... with the power off! I hadn't come across this Megaflo system before. I was puzzled about the two immersions, but I see that the lower one is supposed to be for the economy tariff, and the top one as a sort of booster? As my wife is only...

Yes I do! I haven't started investigating yet as it's in my wife's studio. I'm also aware that you need a certificate to work on the guts of these sealed systems, but I thought I could investigate around it. If I need to replace the immersions then I will call someone in. But, both heaters are...

Heatrae Megaflo type with 2 heater elements and 2 separate programmers. After a thunderstorm (coincidence?) last week the megaflo water heater stopped working. The circuit breaker did not trip out but the light has gone out on the 20A water heater switch. However the lights are on on both of the...
