摘要： 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.

摘要： It is aimed to simultaneously supply hot water at a required temperature to a high-temperature heating appliance and hot water at a required temperature to a low-temperature heating appliance, the low-temperature heating appliance requiring hot water at a temperature lower than a temperature required by the high-temperature heating appliance, and to enhance efficiency by collecting surplus heat when the temperature of the hot water to be supplied to the low-temperature heating appliance is adjusted. A pipe through which flows the hot water at a high temperature to be supplied to the high-temperature heating appliance is branched into a first supply pipe and a second supply pipe. Heat exchange is effected between the hot water flowing through the first supply pipe and return water which has been supplied to a first appliance. The first supply pipe and the second supply pipe are joined again, so that the hot water which has flowed through the first supply pipe and the hot water which has flowed through the second supply pipe are mixed and supplied to the low-temperature heating appliance.

摘要： An auxiliary heater control device can be readily attached to a hot water heating system configured with a simple water circuit without a hot water storage tank, and is capable of preventing freezing of circulating water such that use of an auxiliary heater is minimized. When a sensed temperature tS sensed by a temperature sensor is in a range, a control device increases a rotational speed of a circulation pump. When the sensed temperature tS is in a range, the control device increases the rotational speed of the circulation pump and lowers an operating frequency of a compressor. When the sensed temperature tS is in a range, the control device increases the rotational speed of the circulation pump, lowers the operating frequency of the compressor, and activates an auxiliary heater.
