…Space heating accounts for 64 percent of Canadian residential, commercial and institutional energy consumption. The most common energy sources are natural gas, electricity and heating oil. Compare this with Sweden and Finland, where biomass is the dominant heat energy source. …The two countries use district heating networks and modern small-scale biomass boilers designed to the European standard EN 303-5. …Western European boiler manufacturers have invested heavily in the research and design of pellet boilers, creating efficient and clean-burning systems that are fully automatic and reliable. …These new technologies aren’t generally available in Canada because existing Canadian safety standards are only appropriate for fossil fuel-fired boilers. They do not consider the latest biomass-fired boiler technologies. The Canadian Standards Association (CSA) is working to adopt the European standard, EN 303-5:2002+A1:2023 Heating Boilers – Part 5: Heating boilers for solid fuels, manually and automatically stoked, nominal heat output of up to 500 kW as a National Standard of Canada by early 2026.
