You've come to the right section of our Web site if you want to learn about the most advanced boiler and heating technologies. This section provides a basic, easy-to-understand review of factors that contribute to heating efficiency. We hope it will enable you to feel confident when choosing hydronic boiler or water heating equipment as well as help you design the best overall system to meet your needs.

In addition to the short technology overviews provided here, you may also want to consider the Federal Technology Alert published in 1998 by the DOE's Oak Ridge TN lab. The 8-page publication examines the operational benefits of condensing and modulating boilers and water heaters, relevant applications, installation requirements, etc. Two case studies, energy savings and life-cycle cost estimates are also provided.
