PROBLEM TO BE SOLVED: To provide a heat pump type heater which can effectively utilize in full the quantity of heat given to fluid. SOLUTION: The interior of a house is classified into a main heating zone A1 and a sub-heating zone A2, and a fluid passage is made such that the fluid heated with a heat pump unit 1 circulates to the main heating zone A1 so as to perform heating by heat radiation, and then it returns to the heat pump unit 1 after circulating to the sub heating zone A2. This allows fluid, which has circulated in the main heating zone A1 and radiated only a part of the quantity of heat, to circulate in the sub-heating zone A2 and radiate the residual quantity of heat, by classifying the interior of the house such that the place the user wants to control into desired heating condition is the main heating zone A1, and that the place where the heating condition can not be controlled but comfortableness can be obtained thanks to its being not cold, the place which exhibits heating effect if it is at or over 0 deg.C, the place which is effective to raise the heating effect of the main heating zone A1, and others are the sub-heating zone A2. Hereby, this effectively utilizes in full the quantity of heat given to the fluid. |
