Question about Water Heaters
Hi, baxi 80e gets up to full temp then shuts down,temp drops to 40 degrees and it fires up again until temp reatches 80 degrees then shuts down again.this happens continuasly as long as boiler is turned on,this is also causing problem to downstair rads which are luke warm and upstairs are hot,i have just replaced the temp sensor and safety thermostat and have just put in a new pcb.has anyone else had this sort of problem that can give me some advice,any help or advice would be greatfully appreciated.
Sounds like ur circulating pump is giving up in the end of pump theirs a screw un do this and check that pump isn't seized up if its ok u will see it turning if not change pump, after u change pump test again if boiler starts to over heat again u will need to de scale heat-exchanger ,hope this helps ,any more probs give us a call Joe

I think you will find that instead of modulating as demand requires the boiler is overheating and then re operating after the safety thermostat has operated.
i wilud put some de scaler into the main heat exchanger circuit or add it to the radiators and let it circulate for a while.
also make sure the pump is operating properly to ensure proper water flow.
