19 River Road South
Sustainable Heating Outreach & Education will hold a Renewable Heating & Cooling with Modern Hydronics workshop at Landmark College in Putney, Vermont on May 22nd from 7:30 am to 5 pm.
Retrofitting renewable energy heat sources into existing hydronic distribution systems presents a significant challenge. The high water temperature distribution systems in most buildings from the last 100 years is not well suited for use with air-to-water and geothermal heat pumps. Learn why biomass boilers also benefit from lower water temperatures.
This training, conducted by John Seigenthaler, will examine several options for modifying existing high-temperature systems to make them compatible with renewable heat sources. John will present methods for evaluating tradeoffs between load reduction through building envelope improvement, versus adding different types of heat emitters to the existing system. The program will detail piping methods, control strategies, calculations, and specific hardware to enable retrofitting. The training includes real-world, complete systems examples, and situations to avoid.
Topics covered include:
• New, retrofit, and site-built low temperature heat emitters
• Air-to-water heat pumps
• Geothermal heat pumps
• Wood pellet, wood chip, and cordwood boilers
• Integration of existing or auxiliary heat sources
• Comparison with load reduction through building envelope improvement
• Piping methods, control strategies, calculations
• Specific hardware to enable retrofitting
• Real-world, complete systems examples, and situations to avoid
