Boiler not heating enough Hot Water

[aledrp]

Hi,

I'm having problems heating enough water using a Glow Worm 18hxi boiler.

Having set the system to heat water for about 1 hour, I'm running out of Water after 10-15 minutes worth of showering.

When I first moved into the propoerty, half an hours worth of heating water was enough for two showers. Now, I'm heating water for longer but getting less hot water.

I've had the system checked out but they couldn't see any problems.

Has anyone encountered similar issues? Any suggestions?

Thanks

Do you have a thermostat on the hot water cylinder, located 1/4 way up from the floor.

If so it may have been turned down a few degrees. This would make the boiler cut out earlier not heating your water to the temperature you had before!
