Hi thanks for all your great information vids you do. I have call on a few of them to help me out . Do you know what the difference between the new D2 A3S dosing pump and the older model pump as they have different part numbers. Would be good to know if it would be able to be used on the older heater as this pump seems to be a lot quieter when you did the comparison in your video. Thanks Phil
