I have a primatic system consisting of a potterton myson boiler, pumped ch and gravity hot water. I had to add a radiator and replaced a faulty pump and sticking anti gravity valve. I also flushed the sysytem. All radiators now get very hot within 20 mins.
However, the water heating which only has a short run in wide pipes to the tank now seems to take much longer to get hot even if the ch is turned off (although it does get there in the end!).
This time we drained and filled the system without opening the hot water taps at the same time. (Also occasional loud 'gluging' noises now occasionally come from the primatic tank when the pump turns off. ) Any ideas? Is there a special routine for the order of fill / drain etc.
Any ideas appreciated.
