Energy content of wood pellets

The energy content of wood pellets is approximately 4.7-5.0 MWh/tonne  (~7450 BTU/lb).

High-efficiency wood pellet stoves and boilers have been developed in recent years, offering combustion efficiencies of over 90%. Wood pellet boilers - having less control over the rate and presence of combustion compared to liquid or gaseous-fired systems - are particularly suited for hydronic systems due to the hydronic system's greater ability to store heat.
