my old system is 50 years old. Air and kettling are the issues. Every year, I tell myself just one more year. I hate the thought of replacing it with the new junk available. Sure they are more efficient energy wise, but that hardly means much when it has to be replaced every 10 to 15 years, and the maintenance in between too. Wish I could find another one of these Utica's unused in a warehouse somewhere. I love my HVAC room, it reminds me of what I perceive the inside of a submarine to be. Valves, valves and more valves. Good video friend.

Thanks. Very easy to understand for a diy'er. 👍

Glad it was helpful!

best explanation ever!!! thank you

Thanks for your video it helped me alot.

Looks like my system not only lacks a backflow preventer, but also the water feed appears to be stuck in full port (vertical position). The former homeowner thought the best solution for both issues was closing the upstream gate valve.

What if you don't have a ball valve and have a balancing purge valve instead ?

I have two zones running off one circulator pump which is on the return line just before entering the boiler. I see in your diagram the circulator is on the supply line out of the boiler. Does it matter if the CP is on either the side supply or return?

Is it OK to shut off water flow to heating zone ( To hot water basebords) upstairs and still let the boiler ( in the basement) run as it would normally ?

Well, you wouldn't want to shut off (via valve closing) water flow to that zone and still have its thermostat calling for heat. You *could* turn off that zone's thermostat.

Shouldn't you be doing this with hot water?😮😮😮
