Worcester Greenstar 37 CDi hot water problem

[sako2506]

Ideas please re my just over 2 year old Worcester Bosch Greenstar 37 CDi. After running hot water to a sink or bath, if I want to top up, even after a few mins the water runs cold for quite a while (40secs approx) until it runs hot enough to use. This started about 2 months ago and is getting worse. I'm suspecting the reservoir is'nt working as it should. Everything else works fine.

DIrty system - wasn't cleaned when the boiler was installed.
Your secondary heat exchanger is sludged up. Common as...
