Learn About Hydronic Biomass Heating Systems

Some of the oldest and most common examples are steam and hot-water radiators”. 

Today, many biomass heating systems are using hydronics to deliver heat to living spaces from highly-efficient, biomass-fueled boilers. Biomass (including wood pellets) is preferable over fossil fuels for many reasons, including the fact that it is LOCALLY-sourced and so it does not carry the embodied carbon of being transported around the globe before it arrives in your home.

The Biomass Thermal Energy Council (BTEC) and NYSERDA both offer online courses for HVAC professionals on how to design and install state-of-the-art heating systems supplied by high-efficiency / low-emission biomass-fueled boilers. It focuses on residential and light commercial system applications and how to use modern hydronics technology to complement the operating requirements of biomass boilers.

Heatspring also offers some free online learning units on facets of this topic (see the bottom of this page).


The Biomass Thermal Energy Council (BTEC) advances the sustainable use of wood and agricultural biomass for clean, efficient heat and combined heat and power to meet America's energy needs and strengthen local economies.
