I have had a problem with my new boiler that when it fires up initially in the morning it either locks out or makes a bang as the gas valve takes a long time to open. It has been changed but still the problem persists.
Vokera engineers have been out 4 times so far and another visit is due tomorrow but if it cannot be fixed, can they do something or do i still need to call them out like every other day? They just cannot seem to fix the problem.
Thanks in advance for any help.
