There is an intermittent loud banging sound from the connector box < electrical > that is located on the wall behind the boiler..when the heating and hot water are switched on?
The intermittent loud banging sound from the connector box on a GAH Electrastream when the heating and hot water are switched on could be caused by an issue with the pump or trapped air in the system. Checking if the pump is operating correctly and ensuring there is adequate air charge pressure in the accumulator may help resolve the problem. If air is not present, a faulty accumulator could be the cause. Consulting GAH (HEATING PRODUCTS) is recommended for further troubleshooting.

There is a loud and intermittent noise from the connector box located on the wall and behind the boiler when the hot water and heating are switched on.?
A loud and intermittent noise from the connector box of a GAH Electrastream when hot water and heating are switched on could be caused by a faulty pump, improper installation, or an issue with the electrical components inside the connector box. Additionally, air trapped in the system or an imbalance in water pressure could contribute to the noise. Checking the pump operation, ensuring proper electrical connections, and verifying system pressure and air charge in the accumulator may help identify and resolve the issue.

My control unit will not switch off, if I leave it on 'auto' or 'off' it continues to run
If the GAH Electrastream control unit does not switch off when set to 'auto' or 'off', it could be due to a faulty relay in the control unit. The manual indicates that if a continued temperature rise is observed when all heating elements are off, the relay may need replacing. Checking the control unit relays for proper operation is recommended.
