David Dubois - Project Coordinator Wood Waste to Rural Heat Project
Wood Waste to Rural Heat - Project Goals Work with communities, First Nations and Not-for-Profits assisting them to understand and adopt biomass heating solutions Previously known as the Green Heat Initiative Independent source of Information What does Wood Waste to Rural Heat (WW2RH) do? • Free technical assistance to help determine the best biomass heating solution for the specific application based on the proponents needs. • Developing business cases to help proponents make critical decisions. • Commercial, institutional, and municipal not residential Biomass Heating - Using Wood Chips or
Pellets as Fuel Tatla Lake School Enderby District Heating System
