Renewable Heat NY Training Opportunities

Training Schedule

To qualify for a Renewable Heat NY financial incentive, the system must be installed by a contractor who has demonstrated technical competence in the design and installation of high-efficiency, low-emission wood heating equipment. Installers must have at least two years of relevant experience and have completed manufacturer’s training for the boiler brand they are installing. At least one individual from the company or firm must have successfully completed Renewable Heat NY biomass training or other NYSERDA-approved training.

On-Site Training

Hydronics for High Efficiency Biomass Boilers

This full day design-focused workshop examines best practices for combining modern, high-efficiency wood-fired boilers with hydronic distribution systems. It covers the operating characteristics of wood-gasification boilers, pellet-fired boilers, wood-chip boilers and the latest hydronic heating technology that can complement these high-efficiency heat sources. The hydronic topics covered include low temperature heat emitters, high-efficiency circulators, modern control techniques, and options for water-based thermal storage.

Webinar Training 

Using external heat exchangers in biomass boiler systems with non-pressurized thermal storage
Date: Thursday, March 18, 2020 1pm-2pm
Presenter: John Siegenthaler, P.E., Appropriate Designs, Consulting Engineer to NYSERDA

Description: Many cordwood gasification systems use unpressurized thermal storage tanks.  A common approach is to use coiled copper tube heat exchangers suspended within these tanks.  An alternative approach uses external brazed plate stainless steel heat exchangers.  This webinar exams the advantages of the latter approach.  It also shows how a single external heat exchanger can be used for both heat input to the thermal storage and heat extraction.
