BETHPAGE, N.Y. — Dan Holohan has published a new book,Classic Hydronics: How To Get The Most From Those Older Hot-Water Heating Systems, that the author says takes a fresh look at systems that are even older than those who service them.

“America is a heating museum,” said Holohan, president of HeatingHelp.com. “And most of the heating systems in those older buildings have gone through lots of changes over the years, some of them painful changes. Many of these systems went in before we knew as much as we know today about hot-water heating.”

According to Holohan, Classic Hydronics shows how these systems work, where they came from, how they’ve changed over the years, and what can be done now to get the most of out them without spending a fortune.

Holohan said the 154-page, spiral-bound book will help you “see” inside those older systems, and be able to do things that others say can’t be done.

Classic Hydronics: How To Get The Most From Those Older Hot-Water Heating Systems can be purchased for $25 per copy at www.heatinghelp.com or call 800-853-8882.
