Title
(EN) HEAT PUMP-BASED HEATING SYSTEM WITH BOILER
(FR) SYSTÈME DE CHAUFFAGE REPOSANT SUR UNE POMPE À CHALEUR AVEC CHAUDIÈRE
Abstract
(EN) A heating system (100) comprises a heat pump (110) and a boiler (120) connected to the heat pump by a piping arrangement (130) and being configured to circulate heating fluid between the heat pump and the boiler to heat the boiler by heat produced by the heat pump. The boiler (120) comprises an intermediate bottom wall (123) dividing the boiler volume into an upper volume (121) and a lower volume (122) lying below the first volume. The piping arrangement connects the upper volume to the hot gas heat exchanger (112) and is configured to be set to a first connection mode or a second connection mode. In the first connection mode, the lower volume (122) is connected to the condenser (111) of the heat pump (110). In the second connection mode, the upper volume (121) is connected to the condenser (111) of the heat pump (110).
(FR) Un système de chauffage (100) comprend une pompe à chaleur (110) et une chaudière (120) raccordée à la pompe à chaleur par un agencement de tuyauterie (130) et est configuré pour faire circuler un fluide de chauffage entre la pompe à chaleur et la chaudière pour chauffer la chaudière par de la chaleur produite par la pompe à chaleur. La chaudière (120) comprend une paroi inférieure intermédiaire (123) divisant le volume de chaudière en un volume supérieur (121) et un volume inférieur (122) situé au-dessous du premier volume. L'agencement de tuyauterie raccorde le volume supérieur à l'échangeur de chaleur à gaz chaud (112) et est configuré pour être réglé sur un premier mode de raccordement ou un second mode de raccordement. Dans le premier mode de raccordement, le volume inférieur (122) est raccordé au condenseur (111) de la pompe à chaleur (110). Dans le second mode de raccordement, le volume supérieur (121) est raccordé au condenseur (111) de la pompe à chaleur (110).
