No water flowing from hot tap but cold water is fine

Hi all,



Just had phone call from mother inlaw, there is no hot water coming out of the system but the cold water is flowing normal what could be the possible cause? i have turned of the swith to call for hot water for now but im stuck what to try next.

The system is a gravity system with an emersion heater to hot water up. also there is no central heating part of this system.

Forgot to mention there seems to be a burst pipe down the road could this have an effect this system a severn trent guy was there but on coming out the house he had gone was going to ask him.

Thanks in advance
