摘要： PROBLEM TO BE SOLVED: To supply the circulated hot water of low temperature without impairing the durability of a heat exchanger in a hot water heating system.
SOLUTION: A low temperature circuit-side control is executed when the supply of 45°C hot water from a low-temperature terminal unit is requested (step S101). Whether a detected temperature TH of a high-temperature thermistor is over a dew condensation avoidance temperature 50°C or not under this operating condition, is determined (step S103), the control is switched to high-temperature circuit-side control when TH is 50°C or less, and a target temperature of TH is set to be 55°C (step S104). Then whether a detected temperature TL of the low-temperature thermistor is less than 45°C or not is determined (step S105), then whether TL is over 52°C or not is determined when TL is more than 45°C (step S106), and the burning capacity is controlled to achieve TL of 55°C (step S107). The low-temperature circuit-side control is executed again when TH is over 65°C under this operating condition.

摘要： PROBLEM TO BE SOLVED: To provide a technology capable of supplying circulating hot water of the further lower temperature than the conventional temperature, without impairing durability of a heat exchanger, in a hot water heating system.
SOLUTION: When there is a request of hot water supply of 40°C from a low temperature terminal 3 (TLO=40°C) (Step S101), a flow control valve V1 is fully opened for securing safety (Step S102). Next, the low temperature circuit side target temperature TLe is set to 40°C (Step S103). According to this, control is performed for setting the detecting temperature ThL of a low temperature thermistor 12 to 40°C by an adjustment of the flow rate ratio by a combination of opening of flow control valves V1 and V2 and a delivery pressure adjustment of a circulating pump 5 (Step S104). A heavy line part of the figure 3 is a circulating passage in this state. In this state, determination is made on whether or not the detecting temperature ThL of the low temperature thermistor 12 is maintained at 40°C and the detecting temperature ThH of a high temperature thermistor 11 is maintained at 55°C (Step S105 and S106).

摘要： PROBLEM TO BE SOLVED: To provide a hot water heater capable of accurately computing the water passing flow at the terminal. SOLUTION: The flow Q2 flowing through the low temperature terminal c is found not by a direct detecting means such as a flow sensor, but by the numerical expression Q2=Q1×(T1-T3)/(T3-T2) from a water passing temperature T1 detected by a temperature sensor 2, a water passing flow Q1 of a by-pass pipe F, a water passing temperature T2 detected by a temperature sensor 3, and a water passing temperature T3 detected by a temperature sensor 4. In advance, the detection errors of the respective temperature sensors 1 to 3 are computed as correction values α, β, an the correction values are used to compute the numerical expression Q2=Q1×(T1-T3-α)/(T3-T2-β).

摘要： PROBLEM TO BE SOLVED: To provide a gas water-heater in which a secondary pressure (an output pressure of a gas proportional valve) of the gas can be appropriately held. SOLUTION: A controller of the gas water-heater 1 selects one from the following three modes, in response to a command from an external terminal 37, that is, (1) a normal mode for varying the opening of the proportional valve corresponding to the magnitude of a load, (2) a forced maximum combustion mode for maximizing the valve opening of the proportional valve in a set range irrespective of the magnitude of the load, (3) a forced minimum combustion mode minimizing the opening irrespective of the magnitude of the load. When a normal communication is cut off between the controller 9 and the terminal 37, the controller 9 automatically selects the normal combustion mode.
