Interphase Energy, a Maine-based leader in supplying central pellet heating equipment throughout North America, is hosting Alternative Energy Expo 2014 at their Portland, Maine facility this Friday, September 12th, 2014 from 2:00 – 8:00 p.m. EDT. Free to the public, the expo will showcase a variety of alternative energy organizations providing information and demonstrations as well as speakers, workshops, panels, food trucks and more.

We wanted to join the expo remotely, so we’re sharing a free lecture about alternative energy that we hosted in August with John Siegenthaler, one of our expert instructors with over 32 years of experience in designing modern hydronic heating systems.

FREE LECTURE: TEMPERATURE STACKING IN THERMAL STORAGE FOR BIOMASS HEATING SYSTEMS

This free lecture describes a unique method of managing the operation of biomass-fueled as well as auxiliary boilers for optimum system performance. Beginning with an explanation of why thermal storage is critically important in many systems using biomass boilers, Siegenthaler goes on to describe how temperature stacking is accomplished using multiple temperature sensors mounted in different vertical locations within a thermal storage tank and off-the-shelf controllers. He then explains how to use the temperature stacking technique in systems using multiple biomass boilers as well as systems that combine a biomass boiler with an auxiliary boiler.

The lecture covers:

• The need for proper thermal storage in systems using wood-fired heat sources
• The rationale of temperature stacking within thermal storage tanks
• How to configure standard controls to manage temperature stacking
• How temperature stacking differs when an auxiliary boiler is used

John Siegenthaler, P.E., is a mechanical engineer and graduate of Rensselaer Polytechnic Institute, a licensed professional engineer, and Professor Emeritus of Engineering Technology at Mohawk Valley Community College. “Siggy” has over 32 years of experience in designing modern hydronic heating systems. He’s teaching two courses about biomass with us this fall: Mastering Hydronic System Design and Hydronic-Based Biomass Heating Systems. Both courses are capped at 50 students with 30 discounted seats.
