Thanks guys. I have dropped the temp setting on the thermostat back slightly to see if that helps. Hopefully this will fix the problem. I will update either way in a couple of days.
Richard-the-ninth, there is a small red safety trip which keeps popping. Hopefully dropping the temp will solve...
I have recently had PV solar panels fitted with Solar iBoost installed to heat my water tank through the immersion heater. My immersion heater thermostat now keeps tripping. Do I need to replace the thermostat for a different type? What tests can I do first?
System is Heatrae Sadia Megaflo...
