Hi all,
I am having banging pipes issues, after which the boiler is regularly cutting out,... and hoped that someone on here could steer me in a direction to balancing out my pipes.
It is an open vented system with only one bedroom with TRV's on two radiators. It is a two pipe system on rads, although the Grundfos instructions recommend a PP2 setting I have found it makes no difference which setting it is on.
I have an IDEAL Icos Condensing boiler which I am not sure of its minimum flow rate requirement, but I have attached the manual. The is a graph but no apparent further written details.
I have a Grundfos Alpha 2L pump, info also attached.
Also an inline Honeywell Automatic Bypass Valve, info also attached.
I am having problems with the system banging on startup and believe that it could be down to these settings.
I have drained the system down on a number of occasions and after filling bled all rads, they are all running hot and without any apparent airlock issues. The toilets, showers and taps all operate without spluttering or evidence of airlock. (this is once the system is up and running)
Once the system has been started a few times the banging stops and all runs ok, I currently have the Pump set to PP2 and the ABV set to 1 as I had read that this meant the valve was pretty much open all the time and was less likely to cause problems.
I am planning to bleed the system down this weekend as I am having the old external lead pipe fitted to the stop tap replaced with a modern plastic variety. When I fill it back up obviously I will add some inhibitor and I am going to fit a Fernox TF1 on the boiler return pipe. Not that I believe the system is particularly dirty but as a precautionary measure.
I am also going to also fit an automatic air vent above the Fernox and another above the water cylinder. I am trying to make sure there is no air left in these pipes.
I have had a boiler engineer come and run diagnostics on the ICOS IDEAL HE30 and he told me by way of a computer reading it is running at 110% efficiency!... so I have discarded the idea that this is at fault.
See pics of current set up and plans to install, including documents... link...

Any further advice would be appreciated regarding the settings on the Alpha and ABV.
