Hi. I have multiple questions about my system. I have read a lot on the forum and own The Lost Art of Steam Heating Revisited, so directing me to specific pages for those resources is fine too. I would appreciate any help you can give, and if you can be very specific and step by step that would be great since I am a newbie.
I have a single pipe steam system. There is a hartford loop to provide for the main level, along with another pipe that goes directly off the boiler for the 2nd level.
On the main level I have 5 radiators of varying sizes. All have Hoffman 40 vents.1. None of the radiators heat all the way. They get hot for the first 1/3 and then are cold.
-Is this a problem of the pitch needing to be adjusted?
-Is this a problem of the vents needing to be cleaned? If so, can you please give instructions for the vinegar soak?
-Is this a problem with the valve?
On the 2nd level I have one radiator. This is serviced by a single pipe that shoots off from the boiler and then goes straight up.2. The pipe gets hot until it reaches the radiator, but the radiator remains cold and there has been so sign of any steam getting in (no noise, no heat).
-Is this even the proper configuration to have a pipe not connected to the hartford loop?
-What steps do I need to take the get the radiator hot?3. The pipe leaked a little bit last year at the junction right before it turned to go vertical. I believe we fixed the leak, but the water coming out was black and rusty and overall very dirty.
-Thoughts on if this is a problem with this particular pipe or the boiler or the entire system?
I do not believe the system was serviced regularly (or at all) by the previous owners. The boiler is from 1994 and seems to run fine. We did have someone come out in the spring of 2020 and they added some sort of cleaner to the system. We recently flushed out the water and it took 40 buckets before it ran clear.4. The system obviously needs maintenance, but I don't know where to start.
-Should I add some sort of chemical cleaner regularly? And if so, what and how often?
-How do I clean out sediment from the boiler or pipes?
-None of my pipes are insulated. Should they be for better performance?
-On another post someone mentioned cleaning out the pigtails of pummertol. Does this apply to me? If so, what does it mean?5. At what point do I just scrap the current system and have something different installed? And what would that be?6. Does anyone know of an expert in Denver?
I have had a few people come and honestly they didn't seem to be experts on steam heat.
