another Ferroli optimax

[baldwelder]

Hi, i have an HE31C which has been an absolute nightmare sincew it was installed 3 years ago- trying to get enough money together to get another boiler installed.
The current problem is poor HW delivery especially to the bath and shower, i`m not sure if the fact that they are both upstairs is a coincidence or the amount of water drawn is the factor as when drawing it in the kitchen it seems ok(mostly) but we don`t draw a lot.
The shower usually runs for a couple of minutes then the temperature drops and the shower has to be turned off to 'reset it' this can then be needed half a dozen times during a shower.
Any ideas?
Cheers

Sounds like badly installed on a dirty system without cleaning!

The same will happen to ANY new boiler is thats the case. System needs power flushing whena ny new boiler is fitted!

When was the plate heat exchanger last cleaned?

hi tony thanks for the quick reply, it was installed on an existing system and had all new rads & valves but i don`t know whether it was flushed or not, How would one go about power flushing.
I do know some of the workings of a ch system so i`m unsure how this would help the working of the hot water system but i`m all ears... well eyes as it will be for reading
We had a service just after Christmas, but couldn't tell you what was cleaned or inspected as the clumsy arse 'engineer' turned the ch filling knob the wrong way and bust it, couldn't get a replacement so lashed something together to allow the boiler to be used - unlike himself who will never be used again
