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

The April 10th training at SUNY Morrisville is canceled and will be rescheduled for Fall 2020. 

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.

Online Training

Developed for NY contractors in partnership with John Siegenthaler and Appropriate Designs, this workshop fulfills contractor training requirements to participate in NYSERDA's 'Renewable Heat NY' program.

Webinar Training

Options for domestic water heating in biomass boiler systems

Date: Thursday, August 20, 2020 1pm-2pm
Presenter: John Siegenthaler, P.E., Appropriate Designs, Consulting Engineer to NYSERDA

Registration Link

Description: Most systems using pellet boilers, or cordwood gasification boilers, are designed for space heating.  However, many of the buildings these boilers are used in also have a requirement for domestic hot water.  This webinar explores several design concepts and hardware options for integrating domestic water heating as an ancillary load. Specific topics include: DHW load estimation, internal and external heat exchangers, flow switches, preheating and auxiliary heating, on-demand versus storage based systems, and anti-scald protection.

Learning objectives:

  1. Understand several design concepts for providing domestic hot water in systems supplied by pellet-fired boiler or cordwood gasification boilers
  2. Ability to describe several hardware devices used for domestic water heating
  3. Ability to describe methods for boosting domestic water from a “pre-heat” temperature to a final delivery temperature.
  4. Explaining how to provide safe delivery hot water delivery temperatures to fixtures 

Control concepts for hydronic systems using renewable energy heat sources (part 1)

Date: Thursday, September 17, 2020 1pm-2pm
Presenter: John Siegenthaler, P.E., Appropriate Designs, Consulting Engineer to NYSERDA

Registration Link

Description: The controls used in hydronic heating systems supplied by renewable energy heat sources, such as biomass boiler, heat pumps, and solar thermal collectors have proven to be an area in which installers have some difficulty.  This webinar will emphasize “universal” control concepts used in these systems, and shows how they are implemented with off-the-shelf hardware.   Specific topics include:  Basic switch and relay logic, setpoint temperature control, staging control, sensor mounting, and differential temperature control.

Learning Objectives:

  1. Understand the concepts of temperature setpoint control and differential.
  2. Understand how to use switches and relays to create system operating logic.
  3. Describe how staging control works and when to apply them.
  4. Explain how differential temperature control works and how to apply it.
  5. Describe the importance of details for temperature sensor mounting. 

Control concepts for hydronic systems using renewable energy heat sources (part 2) 

Date: Thursday, October 29, 2020 1pm-2pm
Presenter: John Siegenthaler, P.E., Appropriate Designs, Consulting Engineer to NYSERDA

Registration Link

Description: The controls used in hydronic heating systems supplied by several types of renewable energy heat sources, such as biomass boiler, heat pumps, and solar thermal collectors have proven to be an area in which installers have some difficulty.  This webinar will emphasize “universal” control concepts, explain them in simple terms, and show how they can be implemented with relatively simple off-the-shelf hardware.  It would also discuss practical initial settings, and details such as proper sensor mounting.  Specific topics include:  Outdoor reset control, mixing control, designing control systems using ladder diagrams, example systems.

Learning Objectives:

  1. Understand the concepts of outdoor temperature control.
  2. Learn how to apply injection mixing and mixing using 3-way motorized valves.
  3. See how ladder diagrams are used to design and document control systems.
  4. See examples of complete control systems for application with renewable heat sources

Topic: Case study - Pellet boiler system at the NYSDEC boat maintenance facility at Lake George

Date: Thursday, November 12, 2020 1pm-2pm
Presenter: John Siegenthaler, P.E., Appropriate Designs, Consulting Engineer to NYSERDA

Registration Link

Description: The NYSDEC boat service facility at Lake George uses a pellet boiler as the primary heat source for a floor heating system.  This webinar exams the details used in this system, including fuel supply, boiler, thermal storage, and the distribution system.  I will also discuss some of the monitored performance for the system, and some of the initial challenges met in fine tuning system operation.

Learning Objectives:

  1. Understand the heating requirements and characteristics of the building
  2. Explain the overall operation of the system
  3. Learn about specific details used in the system
  4. View monitored performance results
  5. Describe some initial challenges and how they were overcome.
