I've got a hot water heating system in my home. Some rooms have baseboard radiators (recent ones), then other rooms have old radiator faces like this:
The heat isn't coming up so well in some of these older ones, so I got the face plates off to clean them out to see if it'll help. They're full of lint, hair, etc. After taking the faces off, I can see various parts of the copper piping have got the blue corrosion points on them to varying degrees. The house was built in the 50s, not sure if this is original piping.
I'm wondering what people would typically update these radiators to? Can you buy new ones that are the same size these days? If I were to replace these with baseboard radiators, then I'd have to build out the cut-out area in the wall where these much taller units are currently sitting. They are recessed into the wall.
