Hi, I've never noticed this before ....
We had our boiler serviced today, and the engineer mentioned that gas flow was dipping below 19. The British Gas person came around and replaced the regulator. He then reset the boiler.
I've noticed that when the heating is on the display flashes between the temperature and a funny symbol that look like two letter T's side on :
-I I-
Is this normal ? If not, what should I do.
