Pump over-run stat is next on the list.
And there was me feeling guilty cos I thought it was the high stat Never mind, many engineers habitually change all the stats as a matter of course as they are relatively cheap and once one has gone the rest may soon follow. <<< Saves callbacks. Likewise eliminating the pump may not have been a bad idea as they don't last forever either.i,ve just replaced my pump
Unlikely .... You need to eliminate the POR stat 1stin the summer i had 2 radiators off for decorating.....after they were put back on.....my other rads seemed to be out of balance, so i balanced them up so they were working ok...could this have anything to do with the boiler overheating problem??.maybe its started cutting out since they were off??
Yeswhy doesnt my boiler cut out on LOW....is it because its not as hot???
The limit stat kills the pilot when the water it senses is too hot. The solution lies in finding out why the water is too hot.
My strongest theory is that the pump is turning off too early as the POR stat wrongly cuts off its power supply before it should.
Is there any chance that when you changed the liimit stat that you accidentally put the same one back in?
