Hi All,
I have a Saunier Duval SD30e combi boiler that's giving a little trouble with the DHW.
When drawing hot water, with the tap fully open, the temp only gets hand hot.
It gets a little warmer on reduced flow but will go cooler to cold when the tap is opened to full again then back to hand hot.
What I mean by hand hot is, you can leave your hand there all day without it getting too hot.
When the the central heating is selected and up-to temp, the hot water is OK and hot enough to wash greasy dishes or have a nice hot shower etc.
The boiler is now over 12 years old and the only previous problem was with the DHW flow diaphragm holed and not switching.
I replaced that approx 12mnths ago and all has been OK til now. Any advise on what to check would be appreciated.
Thermistor, diverter, anything else?
Thanks Brian
