I have just had the boiler replaced on my CH. Replaced an old Potterten RS40 with a new Vailant ECO TECH 418 condensing heat only boiler. Everything went ok system now working and ruining nice and hot.
I have one problem that I can't work out. The pipe that feeds the CH pump has water gurgling in it. It's quite nosey. Now when I switch the pump to the second speed setting the gurgling stops but pump is louder. When I switch the pump back to speed 1 the gurgling returns.
Now the system was power flushed and has been fully bled, defiantly no air in the system. Its been bled with system off and with full flow to make sure any air locks are removed. The system was fitted with 2 air vents so any air build up during running should automaticly vent.
Would welcome any feedback from anyone who has come across this problem before.
