worcester 24cdi no hot water

[adp]

To get hot water I have to turn on the central heating as well. Once the central heating changed to position '0' the hot water will stop soon.
With central heating running in the mean time the hot water become very hot. However if I get cold water running in the kitchen mix tap to drop the water temperature, there is no hot water again.
can anyone give me some clue? The boiler is an old worcester 24cdi RSF.

You have a common problem with your boiler. Get a gas safe engineer to take a look.

Unfortunately Ollieg is right. In the interest of gas safety nobody will advise you to open up your boiler yourself. Should you be a gas safe registered installer I am sure Croppie will guide you the right way.

Thanks lads.

You need a gsr in to look at your boiler. We cannot and will not give advice on the installation or repair of boilers for your own safety.

Please go to Gas Safe Register | Ensure your gas engineer is registered. or post a thread in the 'I'm looking for a plumber / gas engineer' section of these forums remembering to include your location.

If you are gsr please increase your post count to 10+ then send a private message to either Gas man or Redsaw who will then check you and then give you access to the gsr private forum.

Thank you.
