I asked a question on the Wall and didn't get an answer. How come?

You may have asked a question that involves safety issues and the pros who visit don't think that you should be messing with that stuff. By not answering you, they're actually looking out for you. Don't get upset; some jobs are best left to the pros.

How did you manage to gather so much great information?

It's been a labor of love over many years. Dan Holohan has a great library of old heating books and magazines, and he also has a lot of friends who find, scan, and share the hard-to-find literature. It's all in our Library, so put it to good use.

Do you screen the professionals who advertise at

No, we don't. The ads that you see in the Find a Professional section of our site are similar to ads you'll see in the Yellow Pages. You should ask for references and talk with the professional before hiring him or her. We do, however, know most of the people who advertise with us from their participation on The Wall (click the Ask Questions tab). If you spend some time reading The Wall, you'll get to know these people. Each advertiser has a link to his or her ad on each of his or her Wall posts. You can also use Search when you're on The Wall to pull up all the posts ever made by any Wallie (that's what we call each other), including all the Find a Professional advertisers.

I see Google ads. How does that work?

Google's robot looks at what's on each page and then decides which ads work best with the content. They handle the whole thing and we sit back and marvel at it all. The advertisers you see in the Google ads pay Google to appear here, and when you click on one of their ads, Google gets paid, and they then share a bit of that with us as the host. You can learn more about this by going to Google and searching AdWords.

I'm a manufacturer. How can I get one of those neat banner ads?

We have a limited amount of them, and they're all first-come, first-served. The investment is very reasonable and the audience is very interested in what you have to tell them.
