I have been using Spirovent Jr. Air Eliminators for many years and it was my choice again for a recent system revamp. I installed them at the inlet of each zone pump since the pumps are installed in the return loop. After initial filling and venting of the zones, the Spirovents quickly eliminated air released as the system was heating up and the pumps are running very quiet.
Most Liked Negative Review
Helped but did not eliminate all the air
Spirovent cost over $200.00, the pipe and fitting were over $100.00 and my faucets still spits out air.

Best Boiler Air Eliminator on the Market
By Big Joe the Plumber
from Long island NY
We install over 50+ boiler a month, every one has a spirovent! Great for eliminating air in your heating system.
The best product for radiant heating
from Lovely NJ
My radiant heating system had problems with air and it took hours to purge and remove enough air from the system under the old method. After taking all the loops down and installing the spirovent, there was no need to spend endless hours trying to remove the air. The flow meters were at .25 gpm in each loop with air in the loop. On speed # 3 with the NRF-36 pump and within a few minutes all the air was purged out of each 3/8" pex tubing loop with an average run of 160 feet. You could hear the spirovent releasing the air. The old air purger with vent valve should become a thing of the past. This is in addition to my old air purger and a must for today's hydronic heating systems to keep air out. Highly Highly recommended. I do not beleive that I will ever worry about air staying in the system again. It should be installed according to manufacturer's instructions.
Everyone should use this product
