About this course

This course examines best practices for combining modern, high efficiency wood-fired boilers with hydronic distribution systems. It will cover the operating characteristics of wood-gasification boilers, pellet-fired boilers, and the latest hydronic heating technology that can complement these high efficiency heat sources. If you plan to be involved in designing or installing wood-based biomass heating systems, this workshop will present a wide range of design details that will help optimize the performance your systems deliver.

This concise course is very useful to anyone who intends to tie modern hot water distribution systems with highly efficient biomass boilers and avoid making mistakes in the process. Well delivered with all the preliminaries needed to match any given design criteria to a satisfactory distribution output.
