Energy analysis of a wood or pellet stove in a single-family house equipped with gas boiler and radiators

Abstract In the residential sector, biomass appliances are widely used for space heating and often combined with other systems. This work aims at comparing final primary energy consumption of different configurations, including a conventional ducted pellet stove wood log using air as heat transfer fluid. A dynamic analysis interaction between stoves systems, such gas boilers radiators, is carried out within typical single-family house in mild climate, TRNSYS software. addition, natural ventilation building considered CONTAM, focus on external infiltrations internal circulation due to buoyancy effect. Results show that device one room promotes airflows adjacent thermal zones, enhancing distribution through door openings, particular when an present. The resulting from simulations wood-burning 21% higher than stoves. results similar 30% increase overall energy, while increases by 22% approximately 40% compared case traditional system coupled radiators which reference. Nevertheless, non-renewable savings 50% 60% wood-log
