I have an Alpha CB28 about 4 years old.
Heating works fine but when drawing hot water the burner cycles on and
off.
The off time for the burner is always about 10.5 seconds
The on time varies when tested but is always the same for that test
i.e. 22 secs on 10.5 off 22 secs on 10.5 secs off 22 secs on........
or 41 secs on 10.5 secs off 41 secs on 10.5 off 41 secs on.....
or 37 secs on 10.5 secs off 37 secs on 10.5 secs off 37 secs on......
It does this when only Hot water is required or if the heating is already on
As I said earlier Heating on its own is fine.
I am really baffled
Any help will be greatly appreciated
