I'm having problems with the top up immersion heater on my direct water cylinder, as it keeps tripping. I've adjusted the thermostat slightly while still keeping the temperature above 60c but to no avail.
Is it a possibility that the main tank immersion heater has blown and I'm over working the top up immersion? At the moment its easy enough for me to keep resetting the top up immersion, but I know that's going to cause me a whole host of problems in the long run!
Any help would be greatly appreciated.
