Hi all The boiler tends to shut down between 75 and 80, according to my thermometer at the place that scatman suggested. It cools off and re ignites at about 55. I also measured the temperature at the pump and the DHW exchanger, and they matched the temparature of the water out of the main...

Thanks for those I will try them in the morning. Although I don't think the air pressure switch and pump were checked, i assume because the heating side seems to be working fine, if anything it seems to be hotter than it was before. no doubt i'll be back, if the past couple of weeks have...

thanks for your replies. the DHW heat exchanger has been cleaned 3 times with spirit of salts. I don't know if he measured temperatures as unfortunately I was at work and didn't see. What temperatures should he have measured? As for running the boiler with the front cover slightly open...
