Gravity heating system

I just wAnted to thank all of you who helped me identify a gravity system i have been working on. I was able to find allot of information on the internet on these systems. Update. The entire home was left to freeze sometime before the present owner. Fortunatly the boiler and mains were in pretty good shape but as i started filling. I had to stop and replace quite a few 3/4 and 1 inch lines that had frozen and split longitutly allong the pipe. Got them all repaired and as my luck would have it we lost four out of nine radiators. I capped the non repairable radiators piping snd moved them out waiting for replacement. So to have some kind of heat in the house i gilled and fired up what i had. Its doing fine although i only have one radiator on the first floor and four on the second floor. The second floor gets hot and the first floor is reaching the setpoint on the stat. Im hoping when i get the other four radiators put back online i can balance them so the second floor isnt so hot. Any tips or pointers would be greatly appreciated. Thanks again for your help.

    You can remove the bad sections of the radiators that are cracked and shorten those rads as long as the end sections are not broken. I had a job just like this and the owner was short on funds. I was able to shorten some of the rads and move them to rooms that were smaller in size and heat loss. The customer was very thankful when he only had to replace a couple rads that could not be used due to the broken end sections. Removing the broken sections is not a job for a timid man, it can be quite time consuming and a lot of work.

    Thermostatic radiator valves (TRV) can be installed on each of the Upstairs radiators. This would give individual control over each radiator not complicated to install with big payback.

    Throw blankets and towels on the radiators upstairs to reduce the output ...
