Running water is cold
All of the radiators are working nicely but the hot water taps only get luke warm. There is also a fluctuation in the temperature of the hot water, it get a little hot straight after it is turned on and then it gets cold.
The pressure on the boiler seems fine.
Do we need to call someone in or is there something we can try out?
it sounds as if you have a combi boiler ,the heat exchanger is usually the problem and needs to be taken out and cleaned if possible ,if not then replacing it but this is not cheap.or it could just be a switch malfunction . either way you need to call an engineer .contact the manufacturer via web site asking for an engineer .

You will need to get a qualified person to look at it.
