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.

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.

Comments about 1-1/4" Spirovent Jr. Air Eliminator (Threaded):

Have a baseboard setup that has tees installed for baseboard to separate rooms... Makes it hard to bleed system fully. The air likes to hide up different legs of the tee. I am hoping this helps. For michaels review: I am pretty sure these are meant for closed loops. If you are having issues with air at the faucets in your home this wouldn't fix it. The air would be excess pressure usual caused by a bad Water Pressure Regulator, located where you water main comes into the house.

The best product for radiant heating

By Cheetah

from Lovely NJ

Verified Buyer

Comments about 1" Spirovent Jr. Air Eliminator (Threaded):

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.

      A:

      Ideally, you should install the spirovent where the water is at its hottest and moving its slowest. Generally this would be right after the boiler but before the circulator.

    Q:

    1" spirovent, how do I know its working, why is expansiom tank cold?

    I have a brand new Spirovent installed on brand new copper with a brand new #60 expansion tank... The ENTIRE system is new. I noticed the expansion tank is cold, its mounted to the spirovent, my supply side temp is 160 return is 140, as I stated, expansion tank is cold and feels very light as if its empty. Whats going on here? System has been in operation for 24 hours

      A:

      I initially had much air in my system. I could hear the air come in the
      pipes and actually hear it release (hiss) through the spirovent. I believe
      mine works well. My system contains about 20 gallons of water. If you look
      at water expansion, 20 gallons raised from ambient (when the system was
      installed) to 150F would expand about a quart. A rise of 20 degrees from
      140 to 160 would only expand a couple ounces. The way the tank is hung off
      the spirovent, once the water would expand, there would be no water exchange
      in and out of the tank and I would think the water would cool to ambient in
      the tank.

      Check the air pressure in the bladder of the expansion tank. If this were to high, water may not be entering the expansion tank. As long as water is able to flow through the spirovent it is probably working.Good luck

      A:

      You know when it's working because you don't hear water moving through the piping. If you hear water sounds, that means there is still air in the piping and it needs to be properly purged. The spirovent will vent some on start up but it's main purpose is to collect the micro bubbles and vent them before they become one big bubble. As far as the tank goes it's there for water expansion not heat transfer. It may get warm over time from conduction but there is no water flowing in it to transfer heat. It has a bladder in it to separate the air from the water that's why it's lighter than the old ceiling hung tanks. Make sure your circulator is on the the supply piping and is pumping away from or down stream of the expansion tank connection. Hope this helps , Joe

      I am not in this line of work so I am not an expert
      I did install the radiant heating system in my house my self with the advice
      and guidance from the "experts"
      It is my understanding that the expansion tank is mostly an air bladder and
      only allows water to enter when the system pressure increases which should
      happen during the heating cycle.
      With that being said the tank shouldn't feel heavy like it its full of water
      and would probably only be hot at the inlet
      You may want to check the precharge pressure on the expansion tank to make
      sure it is compatable with your system
      I hope this helps you

      What is the pressure in the system? If all things are operating normally I
      don't think the expansion tank should be warm. It should not fill and empty
      very rapidly once the system is balanced. If it had the proper pre-charge
      and you have the regulator set to the normal pressure of 15 - 20 lbs. then
      it sounds like you don't have a problem.

    Q:

    I've had a spirovent installed for about 8 years with expansion tank installed below with no problems. Recently the system has waterlogged building up pressure and bleeding off when system is hot.I thought I had a bad expansion tank and replaced it. Didn't solve the problem. Turns out if I loosen the male thread of the tank 3/4 of a turn in the spirovent it will allow the expansion tank to fill but then the threads leak. Something is blocking water from expanding into the expansion tank. Does the spirovent need to be cleaned? replaced?

      A:

      Jeff, 
      I believe the rubber bladder in your expansion tank may be shot. They seem to last shorter and shorter these days and if the initial plumber did not adjust the tank pressure to match the system requirements then your expansion bladder will be flexed in the x-direction more than it should be leading to premature failure. The symptoms you described are very similar to a failure I fixed a year ago and showed the blow-off valve trickling towards the end of every boiler burn time. 
      I don't believe it is your spirovent unless you are putting well water through your system and it is very hard water that has calcified deposits on the brushes in the spirovent.

      My first Spirovent lasted 17 years without issues. I replaced it after making mods to my system (installed indirect hw tank). You may have scaling that broke off the hotter parts of your boiler and settled there. You can take the spirovent apart and examine it. All you should see is a metal mesh inside. If that's not the cause, look for trapped air in the system. That's the more likely cause. Give it a good flush. I mean a high pressure hose flush!.

    Q:

    when installing the spirovent , do you need to add a expansion tank to the bottom of spirovent? can i just plug the bottom because i already have a expansion tank on the bottom of the return manifold. my gas burner was already installed and has been running for a year without a spirovent. i need to add it to get the remaining air out of my system. and according to the drawings for the install, the fresh water is supposed to be piped into bottom aswell. is that all needed for my application?

      A:

      Dear Bill,
        The spirovent does not need the expansion tank coming off the bottom. This is just there as an added attachment for close-quarter systems where adding a fitting will add price and unwanted pipe length to you system. Ideally you'll want 6" to 8" inches of straight pipe to either side of the spirovent to allow your water flow to become laminar so the wire brushes in the spirovent can pickout the micro-bubbles. 
      The question doesn't give a whole lot of details but this vent is for a hot water side of a system. This vent will not have the desired effect if placed on the cold water side of a system feed. I'm trying to read into your "fresh water" meaning here and dispell any possible misconceptions as to the use of this vent. Air extraction should always be done on the hot water side as the physical properties of heated water will readily shed air molecules while cold water will absorb it. 
      The water piping only needs an inlet and outlet so 2 inlets are not needed. 
      You may have to put small coin bleeders in at high points of your system if air is still a problem.
      A pump and 5 gallon buckets also work for trapped air.
      Another thought is if you are using Pex without an oxygen barrier your system will absorb a plethora of micro-bubbles as well.
      Good Luck and hope you get the air out!

      The expansion tank is required in the system, but need not be
      attached to the bottom to the Spirovent, nor does the fresh water
      feed. While a common configuration, it is only a convenience.
      Just an added note, the Spirovent is well worth the extra money over
      other solutions. It works great!

    • VERIFIED BUYER

      A:

      1-1/8 pipe is 1 inch pipe. How do you know that this is the right size pipe for your system? You need to do the engineering and figure the GPM that goes through the Spirovent and then check the Spirovent table to determine what size vent should be used for your system. If you think that is too hard to do: you know why I think it the installed pipe might be the wrong size.
      The 1" vent will match your pipe.

      A:

      Yes, copper with a 1-1/8" outside diameter is considered 1" copper. You will most likely need to use a 1" air eliminator, although it's possible that you'll need something larger (or smaller) depending on the system's flow rate.
