Girlfriend called me up earlier, turns on the hot tap, boiler fires up but
no hot water is supplied, just runs cold. So it seems to me the pressure
sensor is working? What else could it be? Not sure of the Manufacturer,
begins with M i believe, gonna pop over there later and take a look. Any
suggestions appreciated.

thanks,

How long does the boiler fire up for ? Is it only staying for a couple of
seconds or is it staying lit the whole time water is being demanded ?
