Abstract
As a result of isolating doors and windows very well to reduce heating energy costs, some environments' air change rate becomes zero. Two different heating systems (radiator and floor heating systems) widely used in residential applications were compared for a room where the air change rate is zero, using numerical methods in terms of particle concentrations. 3D dimensional CFD simulations show that the floor heating system performs better in removing the pollutants dispersed homogeneously in the room, while the radiator system is more effective in removing the pollutants emitted from a source close to the floor. It was concluded that special care should be taken not to have a source of pollutants close to the ground surface in the environments where a floor heating system is used.

Hot water is used in both heating systems, the floor heating system's water temperature is lower than the radiator system due to the large heat transfer surface area of floor heating systems
The water temperature in the radiator heating system is much higher than the floor heating system

Understanding pollutant concentration distribution in the living environment is one of the primary objective of indoor air quality evaluation and exposure levels. Air velocity characteristics in a room significantly affect airborne particle concentration as particles whose diameter is between 5–10 μm move under air movements' influence (Owen et al, 1992). The air velocity in the heated environment is a crucial parameter regarding particle concentration and every heating system causes a specific air movement in the room. These two heating systems has their own specific velocity and temperature profiles in the room as well as particle motion characteristics. It was reported that as the floor heating system could be operated at low temperatures, it consumes less energy than the radiator heating system (Kazanci et al, 2016)
