Have a service person come and adjust the water flow control valve to ensure the heater does not try and overheat when very low hot water flows are being used – such as the cursed “water saver” shower roses cause. When the service person does the adjustment they will also check and reset the operating gas pressure to assist as well.
OR………you could refit your old shower rose and the problem will more than likely disapear was well!!!!!
