What are the pros opinion about this damper

acl10acl10 Member Posts: 344
I have a Effikal RVGP KS damper on my boiler. Either it functions aromatically or it can switch to hold open damper.

What are the pros opinion on this damper? Is it  a good thing? What is the best setting. Does it do anything for my gas boier with a one pipe system.
