Abstract
When using a plurality of heaters such as heat pump units, capacity is properly distributed according to the required capacity, thereby enabling highly efficient operation of a hot water system. To achieve this, a control apparatus determines the heating capacity of each of the heat pump units in a way that the total heating capacity of the heat pump units reaches the heating capacity required in the hot water system as a whole, and further in a way that the total COP (coefficient of performance) of the heat pump units satisfies predetermined condition. The control apparatus controls each of regulating valves in a way that the heating capacity of each of the heat pump units reaches the above determined heating capacity.
