I have a Saunier Duval SD623.
It does an adequate job of running my central heating system, but when it comes to hot water it is incapable of providing very hot water, and instead pumps out water that is hot, but not very hot. I just had a new shower mixer unit installed, and even at full temperature it is only producing warm water - not hot enough for a shower.
The water will typically come out very hot for a few seconds before remaining at a warm temperature, and if you run a hot tap, the lower the flow you let it come out at, the hotter it is.
Does this sound like something that can be remedied, and if so, will it be cheap or expensive?
It has the digital clock timer thing added to it, and apparently there could be a problem with the thermistor or something according to another website?
Any advice appreciated
