In Hokkaido, most of houses are heated partially and intermittently by using a stove (semi-radiation type). The authors measured the room air temperature of such houses during the heating season, and studied on the controlled room air temperature and the living way affected by the thickness of thermal insulation and type of heating system. The purposes of these reports (part-1, 2 and 3) are to point out from those results what kind of changes shall be brought on the room air temperature and the usage of heating according to the improvement of insulation in the future. In this report, the varying patterns of the temperature at the ceiling θ_c and of the floor level θ_f are mainly discussed. In the case of the partial and intermittent heating by using a stove, the temperature difference of those two levels and those varying patterns change according to the fall of outdoor temperature. For example in the early season of heating, the varying patterns of θ_c are high in the morning and low in the evening, and those of θ_f are flat in the daytime. In this case, the room air temperature increases easily and sufficiently because it dose not get so cold yet and the radiation from a stove dose not become so strong to the living space. And in every house during the coldest season, the varying patterns of both θ_c and θ_f are generally low in the morning and high in the evening. But with supplying a little heat at night or with reducing some heated rooms, those varying patterns become like the patterns in the early season of heating. The reason is supposed as follows. In the coldest season, as the temperature at night becomes so low, more heat supply is required in the morning, the sufficient warmth is not obtained by room air temperature but by only the direct radiation from a stove. And the supplying a little heat at night or the reducing some heated rooms is the response of living to the coldness existing the adjoining rooms or at the floor level, these patterns are supposed to be the results of the response to keep the human body suitably warm.
