Heating problems in a 10-storey apartment building
Once again this year, our co-op building is having heating issues. Chiefly, it's boiling on the lower floors and cold on the upper floors.
I'm not sure if there is something that can be done by our super to maintain radiators better (?) or if it's a function of an old system. If you have any suggestions, we'd love to hear them. With heating prices on the rise we hate to have to see people on the lower floors with their windows open and people freezing on the 10th floor. Thanks.

I had a similar problem in our building. Frezing on the lower floors hot as lava on the upper floors (Boiler is on the roof)
The building had a plumber expand some of the baseboard heating in out unit (and some others on our floor) and it really worked great.
That could be an option.

you have to bleed all radiators before you turn heater on.. otherwise there's too much air in the system/

several strategies. 1) install theromstatic valves on the radiators on the lower floors. that will shut the individual radiators off if it gets above the set temperature in the room. 2) insulate any exposed radiator piping, especially those fat ones that run from ceiling to floor. they throw off alot of heat. 3) turn off the radiators using the existing knobs. But shut the valve completely. half way will cause knocking.

The system needs to be balanced.
There are too many reasons why it may be out of balance to list here.
If it is a steam system, it's all about venting and having the right size boiler.
One thing's for sure, though. If the system isn't distributing the heat effectively, it's not running efficiently.

can you remove some radiators? that helps and many older buildings have way more than needed.
also, the pressure may be off. you should check gauge after you bleed radiators (your super should bleed them all) at the boiler.

have insulation blown into the roof. This will keep some of the heat from escaping through the roof and will keep the upper floors a bit warmer.
