Problems with my trusty old Vaillant.
When the central heating or hot water tap are turned on, the main burners will ignite as normal. After a second they used to come on even stronger, but this no longer happens.
Result is warm, but not hot tap water; and central heating that take slightly longer to heat the house.
Additional things that may be worth saying
- I have to pump up the expansion vessel every 3 or 4 months.
- took the diversion valve apart and gave it a good clean 6 months ago. (The rads used to come on with the hot taps, but this is now fixed)
Any ideas?
Cheers
