Works as it should
Good price, arrived quickly, and is doing its thing removing air for a radiant floor heating system. Heat transfer improved almost immediately after installing.

Great product
I like installing this product in on all my new boiler jobs. Before using this product, the customer would have some complaints about air in the systems or noisy water. This eliminates all the air, solving the issues every time

I would buy this again.
Installed the Spirovent on my wet base boiler with cast iron radiators. It helps maintain perfect pressure. The folks in customer service at Supply house couldn't have been nicer or more helpful. Honest well meaning people.

Works great
I had an old taco air scoop on my boiler that didn't seem to do much. I had to bleed my radiators every so often and could still hear water trickling in the pipes. I installed the spirovent and all of the air was out of the system in a day or so. I don't hear water in the pipes anymore and my 2nd floor radiators are hotter then they have ever been.

Perfect every time!
I've used these vents for years, I can't imagine installing anything else in our boiler systems.

What an improvement!
I had an "ancient" American Air Purger (Amitrol 443) that wasn't scooping anything anymore. While it would have been easier just to replace it with another 443, I'd heard so much about the Spirovent that I just had to give it a shot. So far, no air-lock at all. Absolutely worth the trouble. Just note: it's much taller and not as long as your cast iron "T" scoops, so plan for that.

better than Ronco set it and forget it
Easy fix to having to return to a new boiler installation to bleed air due to the O of H2O being pushed into air pockets.

Q: I had a professional install infloor radiant heat using plex. There is no Air eliminator but there is a expansion tank and a mixer. I just added on to the system and now there is a lot of gurgling going on and the boiler shuts down even though I added water and show 20 lbs pressure. If I add the Air Eliminator will that take care of the problem?
Asked by Jim 15 years ago

Verified Reply- PexSupply StaffThe air eliminator will definitely help, but you will still need to bleed the system.

Q: I'm installing a Solo 110 with a Smart40 tank. My plan was to install a Spirovent in the system to eliminate air, but this will be a closed system. Does that mean that I should not use this so I don't water log the expansion tank? Thanks!
Asked by Slightly Confused 15 years ago

Verified Reply- PexSupply StaffThere is no problem with using Air Eliminators in closed systems.

The expansion tank is for the expansion of the hot liquid not air. The air separator will not effect the operation of the ex-tank. the tank helps control the system pressure. But then what do I know I'm just an electrician. Anybody else agree with me???

Q: Does this air eliminator ever have to be disassembled and/or cleaned, mine has been in service for 14 years?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffIt does not, unless any problems arise. If you are having issues, please refer to page 2 of the Installation Guide for maintenance instructions: http://s3.pexsupply.com/manuals/1298567552219/48486_PROD_FILE.pdf

Asked by Bill 15 years ago

Verified Reply- PexSupply StaffThis should not create any problems, other than a little bouncing before everything settles down after a quick fill. The product is normally used in this manner.

Q: I own a Brownstone in NYC which is heated by a gas fired boiler handling four zones in a closed loop system. Naturally, the entire system must be purged once a year, but between the third and top floor there is a recurring air lock which requires more attention. There are bleeder valves on every radiator but they are not very reliable. Would you sugest eliminating those bleeders and installing one of the air eliminators on each zone originating in the basement, or would it be sufficient to do so only on the problem lines?
Asked by PB 15 years ago
Add your answer
Verified Reply- PexSupply StaffWe suggest that you leave your existing valves in place and add this unit to your main piping in the mechanical room.

Q: My radiant heat manifold is installed in the basement, with the PEX running overhead to heat the first floor. I'm guessing I have air in the PEX lines, because at the start of the heating season I don't have much heat until I purge the lines by hooking hoses up to the manifold. Will this product keep the air from getting into the system, and I won't have to purge the manifold and lines every year?
Asked by Nate 16 years ago
Add your answer
Verified Reply- PexSupply StaffYes, this product will help eliminate air from the system. If this is an open loop system though, there will constantly be air in the system in which case you would have to purge the manifold lines every year regardless.

Nate, I used my 3/4" on a copper baseboard hydronic heating system and it removed all the air and each heating season there is nothing for me to do except enjoy the warmth. Great product. You contact Spirotherm directly and they get back quickly. -StanS
