Hydronics for High Efficiency Wood and Pellet-Fueled Boilers

John Siegenthaler
Appropriate Designs

This session covers the design of combisystems using wood gasification boilers and pellet fueled boilers to provide space heating and domestic hot water. It focusses on systems for residential and light commercial applications. Although there have been significant improvement to the efficiency of wood gasification and pellet-fueled heat sources, there has not been equal emphasis on the proper design of the overall systems in which these heat sources are used. Heating systems supplied by wood-gasification and pellet-fueled boiler can benefit from state-of-the-art hydronics technology. This session shows how to properly integrate that technology to maximize the performance of these renewable energy heat sources.

Dead Men's Steam School

Dan Holohan


This all-technical seminar will make you familiar with the many types of old steam heating systems and what can go wrong with them. Dan’s easy-to-follow explanations will have you seeing inside these old systems. You will become a much better troubleshooter after this class and will leave it with a solid overview of steam heating as it applies to older buildings of all sizes. Among the topics Dan will cover are: pressure-reducing valves; steam-to-water heat exchangers; pressure settings; steam traps; the importance of pipe insulation; steam heating loads; and balancing systems with properly sized air vents.
