Well, and it was going so well. The system has been working fine
It's an vented system.
My Keston 25 this morning is making noises like a Mad Scientists
Laboratory ... bubble bubble bubble.
Symptoms of the Patient:
1. Only some of the rads are heating up, and at best they're getting
2. Going outside to the flue, the bubbling sound is more pronounced
and the occasional drip of water is coming out of the flue. The
normal condensate drain is working.
3. The low water pressure light is intermittently coming on
4. Boiler has problems igniting.
o About to pop up into the loft to check the header tank.
Any more thoughts on what I should check as apart from this I'm at a
Jack of all trades, master of some
