With older systems like that you would want to look at system efficiency overall. And water quality with a ph test. One more involved step would be to remove the radiator to flush it through and if you are seeing internal sludge or degradation then I would look to powerflushing. At some point sludge (corrosion iron oxides ) will sit and even with a magnaclean filters on a hydronic system it won’t get rid of that sludge. That’s when a hydronic powerflush really helps to get those older radiators working again. Of course a simple fix like bleeding air works and I suspect those older trad rads are better than modern ones in better built lasting a long time before internal corrosion really makes a difference. It’s all dependent on a customer. At the very least you can tell a customer what they could see later down the line. It’s a fine balance with older system like these probably more problems can arise with powerflush with pinhole leaks become more evident and leaking valves.

I guess it dont get much easier than that lol
