Well, I havent had a shower for two days now and its not thru want of trying. Ive got CH but the taps run lukewarm for a minute or so and then go cold. However, I did manage to get half a bowl of piping water this morning, but then it gave up the ghost. Any suggestions? It has been suggested it could be the DHW thermistor (whats that when its at home?) or the heat exchanger scaled. I shall be spitting feathers if it turns out to be that as the boiler is not quite two years old and Ive had it serviced. Also, as its a very hard water area round here Ive had the water softener changed twice in that time, the last time in March. Is there anyone who can give some pointers?
