Fired up boiler in house we bought.Getting heat to all elements except one room,living room which has the biggest elements and closest to the boiler.inlet valves are open.Curious about circulating pump,should you here it running?Got heat upstairs.

thanks Stan

There should be a air bleeder in the system. Sounds like it could be air locked. If the other zones are working try shutting them off and open the one to the room that isn't getting heat. Feel the pipe to see if hot water is going that direction. If there is a air lock you can loosen a bleeder and then re tighten as that may solve the problem.
Some systems have a circulating pump and a zone valve for each room controlled by a thermostat.
Make sure the zone valve is opening. Other systems have a circulating pump for each thermostat. Those pumps usually are so quiet you can't tell if they are running or not.

Its a single zone system.I now have heat in one of the elements in the living room.I purged any air out of system at the valve on return line at the boiler.Maybey it just takes awhile to activate whole system.Just seems like those two elements would of heated first.Another question,upstairs bedrooms still have the old radiators,at the inlet there have been some type of valve installed numbered 1-6,are these just a low cost temperature control for bedrooms instead of a dual zone system?

i'm not sure what that valve labeld six is. But I have a zone with pipes going to two areas. They had a valve that seemed to adjust how much water went in each direction. You could adjust it with a screw driver to get the balance you wanted. Once set you shouldn't need to change it. Maybe that is what you are referring to.

I presume when you say "elements you are talking about Baseboard heating elements. All the elements should have a "coin vent on them at the return side. The fined pipe is usually suported by brachets in the frame. If posible lift the return end a bit, and suport it with a small block of wood. That way all the air moves up to the return side where you can bleed all of it off. If it is a single zone system, each element should have a "monoflow " Tee on the return side pointed in the proper direction to pull hot water through the element above the floor and back down to the supply/return pipe. If the system doesn't have an auto air eliminator, usually mounted adjacent, and above the boiler, a casting that also serves to suport the expansion tank and water inlet pressure regulator and back-flow preventer, you may have to manually bleed of several elements during the heating season. Good Luck

cant locate any vent at return end of elements.I do have an air seperator and expansion tank on outgoing line over boiler.Still have no heat in one downstairs element and very little upstairs.

I have wall radiators...... Air is like a bad ground on your vehicle/trailer... Nothing works right, it's hard to find, but when you do the world is perfect again..... that expansion tank is not a bleeder. If you don't have a bleeder on each element, you's gonna have to be patient or find someone that'll tell you the trick of the trade....
