Hiya been on the phone with veissmann tech help and they have also suggested that this may be caused by blockage. They do not send out engineers but asked me to find local installer through their website which I will do and ask for quotes. Thanks for the help so far.

We have the same problem with that boiler. Replacing the plate heat exchanger didn't fix it for us. Did you manage to resolve the problem?
Thanks.

So its still got the same problem of running hot then cold like the 3 year old problem above?
Can you run the water flow from a hot tap only into a dish for 30 secs, then measure this and double it to give you the HW flow in LPM.
