This article explains in detail how the efficiencies of wood stoves are calculated using the higher heating value or lower heating value of the fuel. In case of condensing wood stoves, the higher heating value must be used.
The US uses higher heating value, HHV, as the basis for calculating efficiency, Europe uses lower heating value, LHV.
This leads to European stoves having calculated efficiencies greater than US stoves, which deceives lay people in the US,…Continue
