Boiler help

So as I had such a good response last time, anyone shed some light on what may be going on... for ages my hot water has only lasted about 5 minutes before going cold, very annoying... had someone come out and look who said the heat exchanger had gone... worcester bosch replaced this under the guarantee all good, worked great for a few days... now same keeps happening again hot water for 5 mins then goes cold and the only way i can have a proper hot shower is if i turn my heating on for a bit, anyone know why this would be as I have no idea!

    Is the water heated by oil or LPG or what?

    You have posted in the LPG, heating oil board?

    For advice on boilers. The DIY board would perhaps have been better. But if its under guarantee get them back.
