Forced Hot Water Heat: 2 rooms are cold!

I have a newborn son and our heating system; forced hot water-1 zone, works well except that two bedrooms (including nursery) which are on the second floor on the opposite side of the house from the boiler are pretty cold and not as hot as all the other rooms in the house. I have had the boiler serviced every year since we have been in the house; 2 years, but didn't notice the difference in temp in the two spare bedrooms.

Does anyone have any suggestions or recommendations on what I can/should do if anything?

    Sounds as if...

    the system might have air contamination - which slows flow and prevents end-of-line rooms to get full flow. Can you follow the direction of flow from the basement piping? If so, and if the last rooms of the loop are the cold ones, the air-contamination potential is large.

    If the system is mono-flo (so-called "one-pipe") and - the circulater is not "pumping away," your lucky to have gotten two years of even heat at all.

    Unless you are pretty mechanically inclined, the solution could be so many variables, this forum would be slow to determine the problem, much less fix it.

    At the top of this page is a tab marked "resources." The first topic on that "pull-down" is Find A Professional. If you plug in your zip, nearby help may be at hand.
