<p>This invention relates to a method for heating room space of a building. According to the method, heat is conveyed from district heating water to a heating liquid of heating circuits (6, 7) for heating the building, tap water and supply air (A) of ventilation. According to the invention, the heating circuits (6, 7) for heating the building and the supply air are connected in series in such a manner that the heating liquid flowing in piping (5) heats, after passing a heat exchanger (4), first the heating circuit (6) for heating the building and thereafter the heating circuit (7) for heating the supply air (A). On account of the invention, the temperature of the district heating return water is lower than in the known apparatuses.</p> |
