Hi,
I have a Potterton Suprima 40 boiler with EP2002 programmer. I seem to have a problem with the boiler taking ages to fire up. It seems to take on average an hour to start when the programmer fires it up for the central heating. I have no issues with the hot water.
I thought it was the room thermostat at fault but I have just replaced it with a brand new one and I still have the same problem.
Could the 3 port myson valve have anything to do with it. For about a year now it makes a hideous buzzing sound which it never use to do, only when the timer kicks in to start everything up in the morning. It doesn't make a noise later on.
So in summary
1) Heating takes about an hour to start up. Once started no problems, room stat switches off with change in temps etc.
2) Is my Myson 3 port power extra valve either faulty by it's own noise and or is this the possible cause of the boiler not starting .
Lastly just out of curiosity. How long should a boiler take to fire up when the timer switches it on to start the central heating.
Many thanks
Lee
