There are several potential reasons why your system may not be producing as much hot water. Sediment build-up, thermostat issues, scaled up heat exchanger, Glycol is due to be replaced (servicing), insufficient tank size, and leaks in the system can all contribute to decreased hot water production.
We would recommend seeking the professional assistance of your heating engineer for a thorough diagnosis.
