Northeast Biomass Heating Expo
John Siegenthaler, P.E.


A “Hydronics for High Efficiency Wood-Fired and Pellet-Fired Boilers”workshop has been added to the sixth annual Northeast Biomass Heating Expo scheduled for April 9-11 in Portland, Maine.

The addition of the technical session underscores the depth of specialty knowledge that will be available to conference attendees and highlights the Steering Committee’s consistent effort to increase practical learning for engineers, architects and HVAC specialists.

The day-long technical workshop will be led by John Siegenthaler, P.E., the hydronics editor for BNP Media’s Plumbing Group and a columnist for pme. The six-and-a-half-hour April 10 workshop will feature topics key to the optimal installation of biomass (e.g., wood chip, pellet and log) boilers for space- and hot-water heating in residential and commercial settings.

Topics to be addressed include: 

  • The importance of hydronics to renewable energy;
  • Wood gasification boilers;
  • Pellet-fired boilers;
  • Thermal storage options;
  • Boiler protection options;
  • Low-temperature hydronic heat emitters;
  • Instantaneous domestic water-heating assembly;
  • High-efficiency ECM-based circulators; and
  • System examples.

Workshop attendees also will receive a complimentary lunch and snacks, access to the conference and expo, and may apply for six continuing education units. Depending on the attendee’s needs, workshop participation may be counted toward state annual licensing requirements. Space is limited and additional registration fees apply.
