Very high chance that the flow switch on the left hand side of boiler has a fault . It has a wax capsule in it that makes the insides of the valve move from heating to hot water .
Old boiler now, so parts may not be avialable capsule was about 20 quid and whole valve about 150
Remote possibility that it is the calorifier but these where bullet proof

It could be a boiler fault causing only low flame.
It could also be a restricted gas supply or meter regulator fault.
How is the flame size on the gas cooker when you turn the boiler on?
Several possibilities but all would need a CORGI.
