I have a oil fired cast iron peerless boiler installed in 1996. It feeds cast iron radiators with a supply and return on each radiator. The issue I'm having is the master bedroom is 5-6 degrees colder than other rooms adjacent to and on the same floor. These rooms are on the second floor and there is also 2 bedrooms on the 3rd floor. All other rooms on 3rd floor seem OK so water is making it all the way up. Pressure is consistent at about 19-20 psi.
I have had several people look at it with no solution. Bled radiators, changed valves, drained down boiler, balanced system all to no solution. The only thing I can think of is those radiators aren't fully heating up. Could this mean there is sludge in there blocking flow? When you google this topic, there is a ton of info on it in the UK. They literally take the rads off, take them outside and wash out with a power washer. Gunk comes flying out and it's like new. Every tech I talk to does not believe this is the problem, but offer no solution either.
Any thoughts are appreciated as I am very frustrated with this issue!!
