Hot air

Tuesday, November 13, 2012

I have a hydronic heating system in my home. When water is added to the system and heated, air is separated from the water. This air collects in large bubbles in the pipes and makes enough noise to wake the dead at night. I picked a high spot in the piping and installed this automatic air vent. It did the trick. Now I can hardly tell when the system is running. Great product!!

Everything. That's why I bought it.
