Can anyone recommend an automatic vent such as the ones here?
I want to put some into my baseboard heaters and was particularly looking for some that didn't require pipe cutting/re soldering. I am not sure if they exist, but I had spoken to a plumber that worked on my heat earlier this month and he said that he had some that just required you to drill a hole into the pipe and attach something. Any ideas what this might be? If it is as easy as he makes it out to be I might as well do it myself. Would also be good to know if the valve he's suggesting is a bad idea.
