Good air vent brand?

Hey guys,



This might be a bit of a gray area since advertising is not

allowed here, but I’m looking for a recommendation on a good brand of air vents

for home use (the stuff at Home Depot is not cutting it) and the name of a good

on line vendor as well.



I’m looking for reliability, low noise, and a good range of

sizes.

    vents

    The Gorton vents are well thought of on this site as are the Ventrites (not easy to find); the Hoffmans have seen some troubles just recently and then you have the Mai-O-Mist which looks much like the Gortons. The Durst you find at the big box stores are best left on their shelves.



    A good online source for vents is -

    Hoffman Fan

    I have to admit that I'm a fan of Hoffman #40. They're nice and slow and very reliable. The Hoffman 1A has a lot of fans because it's adjustable. But, I find the adjusting mechanisms is so sloppy that adjusting by the dial on top is futile. Slow venting radiators helps greatly in getting even steam distribution. You can usually find #40 vents on ebay for reduced prices.

    Maid-o-Mist

    You can buy Maid-o-Mist at Home Cheapo, but caveat emptor. If the label that seals the box is cut, open the box and check the vent. First, make sure it isn't used. I don't know if they just put customer returns back on the shelf or if customers are exchanging their old ones for new ones, but I see used ones on the shelf all the time. Second, make sure the orifice is screwed into the outlet and that the number or letter stamped in the orifice is the same as that marked on the label.



    Amazon is also a good place to buy M-o-M vents. Amazon and Home Cheapo both have smartphone apps, which makes it easy to compare prices. You can even scan the barcodes if you find them in a store and want to check their prices online.



    One thing I like about these vents is that they come in the same size as the Gortons, but you can remove the orifices, so when you're balancing your radiators, you can just swap orifices around instead of having to unscrew the vents. Once you've got all the right size installed, you can replace any vents that go bad with the extra ones you bought while you were balancing, swapping the orifice, if necessary, and when they run out you just replace it with the same size Gorton. Think of the M-o-Ms as "training" vents.



    Last year BobC found a Maid-o-Mist that came with a complete set of orifices. I followed his lead and found the same model at Amazon. I got a good deal, but I don't know if they still have them at the same price.

    Gorton

    I'm definitely a Gorton man.  I used to have Hoffman 1As on all of my radiators and I gave up on them.  Switched to Gorton and have had zero problems.



    I also believe Gorton's are about as quiet as they come.  No clicking.

    VentRite #1 Radiator Vent

    Thanks for the link on where to get VentRite #1 vents. Price wise it looks like a good source. 
  • Just as important-the pressure

    Make sure your pressure is low and that you have enough main venting to enable 2 ounces of pressure to push air out of the mains as the boiler is starting to steam. Verify that low resistance to venting with a good low-pressure gauge.

    Most radiator venting problems are the result of inadequate main venting, or excess pressure. If you can hear your vents all the time, something is wrong.--NBC
