Radiator vents

tec Member Posts: 3
Does anyone have a opinion on Maidomist radiator air vents. I was using Gorton vents for both the mains and the radiators for the past 10 years and it came time to replace them. I replaced them with the Hoffman #75 on the mains and the #40 on the radiators, that brand seems to work well, but time will tell. My issue is the Hoffman brand is pricey. I have two other boilers that will need the vents replaced, but I'll wait to see how the Hoffman brand performs.
I'm not trying to be cheap, but with three boilers and 22 radiators, it starts to add up to a good chunk of change. Thanks'

    I have them in my residential home for 10 years no issue. That said, your mileage may vary.

    What Gorton vent did you replace with the Hoffman #75. Sometimes this isn't a question of price, but value. The Hoffman #75 vents a little faster than a Gordon #1, but less than half of a Gorton #2. Need to look at venting capacity as well as price.

    All I use are Maid O Mist from supplyhouse.com

    As everyone hears me say too much, they are great because you can swap the orifice pieces to resize them without having to remove the whole vent. And they are very inexpensive.

    And Gorton copied their patent
