<P>PROBLEM TO BE SOLVED: To provide a hot water supply space heating system which is constituted by combining an electric heat pump with an other heating device, enables hot water supply/space heating at higher energy efficiency without causing the shortage of a hot water supply/space heating capacity and does not exceed a maximum amount of contract electric power (or contract electric current). <P>SOLUTION: The hot water supply space heating system includes: a combustion heat source machine 20 heating hot water supply hot water and a space heating circulation heat medium by combustion; a heat pump device 10 heating the supply hot water and the space heating circulation heat medium; an electric power consumption detection means 70 capable of detecting electric power or an electric current supplied to be consumed from an electric power supply device 60 to a plurality of electric power load facilities including the heat pump device 10; control means (11, 21, 51); and at least one of a space heating radiator 30 and a hot water supply device 50. The control means controls electric power supply to the electric heat pump 12 so that the electric power consumption detected by the electric power consumption detection means 70 does not exceed a preset threshold. <P>COPYRIGHT: (C)2012,JPO&INPIT |
