ABSTRACT

Space-heating using wood stove is a popular solution in many European countries. Nevertheless, nominal powers of state-of-the-art stoves are oversized compared to the needs of highly-insulated building envelopes, such as passive houses. In this respect, a simplified wood stove model has been developed in order to investigate the thermal comfort using detailed dynamic simulations (e.g. TRNSYS) at an acceptable computational cost. A specific experimental setup has been developed to validate this modelling procedure, especially as regards the interaction between the stove and the building. The largest source of error appears to be the thermal stratification in the room where the stove is placed. This can simultaneously affect the conductive heat transfer between rooms, the thermal comfort sensation in the room as well as the convective heat exchange by flows through doorways. Nonetheless, the present work proposes a correction to circumvent this last effect. Finally, thermal comfort measurements during the experimental campaign confirm the conclusions of previous simulation results (Georges, Skreiberg, & Novakovic, 2014), supporting their proposed guidelines for the integration of wood stoves in passive houses.
