Hello all,
First post so please be gentle :wink_smile:
Little help if you wouldn't mind, i have an issue with the hot water on my Worcester 28CDI, been in for about 6 years, about two years ago i replaced the diverter valve as i could only get hot water whilst the heating was, on, pig of a job but did the trick. Now i have a different issue, i can get hot water without the heating being on, but only if i turn the tap flow rate down, and even when i do this the boiler cuts out now and then and then re-fires.
It takes ages to fill a bath, and is causing problems with my showers.
After doing some digging around on here and on tinterweb i suspect the water to water heat exchanger is scaled, am i on the right track?
If the hot tap is on full i only get luke warm water, its almost as if the boiler cannot heat it up quickly enough. It was not like this when first installed, but i suspect has deteriorated over the years without us really noticing, we started turning the tap flow down on the bath about a year or so ago, but not as much as now.
should i be measuring the flow rate from my taps?, could it be a gas problem, in which case i will have to get a man in, should i be checking the pressure in the expansion vessel, or have i missed anything?
Pressure gauge is always constant no loss
I am thinking at the moment replace water to water plate exchanger, and while i have it in bits replace the diaphragm in the diverter valve, just while it is in bits as i know they are prone to problems.
Thanks in advance.
