The heating is working but I have a problem with hot water. The demand light is not coming on or coming on for a few seconds then clicking off. The only way to get constant hot water is to run it when the heating is on. Can anyone help please ?

There is a problem with the water flow detector. What model? Probably uses a diaphragm and it has split.
