Hi,
I have poterton prima boiler and cylinder system regularly serviced, the problem is that when the HW cycle only kicks in there is a lot of gurgling noises and the sound of trickling water comming from within the boiler this continues whilst the water is being heated. I have just had it serviced and had a new auto air vent valve fitted the engineer said that the sound is caused by air within the system and should settledown after a couple of cycles, well day two and it sounds worse. My question really is why does this only occur on the HW cycle.
