Hi,

I have a Tristor Telford thermal store in my flat and recently, it's started it make such loud banging noises, it sounds like a car crash pr someone busy banging on the inside! It will make these noises when the system is turned off (as there is no timer) at least 4 or 5 times an hour at all times of the day, when it's heating up, when I turn taps or my shower on. Basically it happens regardless of whatever I'm doing.

I've had a plumber in to look at it and he topped up the pressure. This made it all stop for about 3 weeks but then it started happening again. The pressure is still as it should be but we can't work out why it's making such a huge noise

Do you have any idea what it might be? It's driving me crazy and wakes me up at night!

Many thanks​
 
get another plumber to check it over, could be several things from airlocks, over pressuring, overheating etc etc
