John Siegenthaler, P.E., will present informative and practical instruction on low temperature hydronics for renewable energy systems. The educational event runs from 7:30 a.m. to 5 p.m. May 22 at Landmark College in Putney, Vermont.

The session will cover why air to water heat pumps, geothermal heat pumps, and biomass boilers are not just for high-performance buildings; retrofitting high temperature distribution systems will be an important part of controlling heating costs, and meeting the country's renewable thermal energy goals. The instruction is filled with real-world lessons learned and situations to avoid — essential knowledge for heating professionals and engineers who are ready to ditch fossil fuel heating, according to Siegenthaler.
