I have boiler Optima 701 and its seven years old. The problem is that with the tap water I can get hot water for a few seconds and then it turns cold and then goes hot again and so on. I have noticed that the intensity of flame decreases dramatically and then increases, then decreases and then the boiler turns off and then turns on and so on.

Please Help.

Thank you.

Hiya, i have this prob aswell - check your water pressure on the boiler, should be 1 - 1.5 bar. If not, top it up and give the taps another whirl ..
