摘要： PROBLEM TO BE SOLVED: To heat a room up to desired temperature rapidly in the case of large heat load suppressing the increase of the size of a heating system by arranging in an air duct an electric heater that can perform heating separately from a heat exchanger for heating. SOLUTION: When a heating mode is selected by the turning-on operation of a heating operation switch 17b, a thermally operated valve 13b is opened and heating operation is started to heat the room up to a target heating temperature that is set by a temperature setting switch 17d activating only a circulation fan 8. The magnitude of the heat load is judged by comparing a detected temperature detected by a temperature sensor 15 with a switching temperature for heating and energization of a ceramic heater 14 is turned on or off responding to the judged magnitude of the heat load. Therefore, the room is heated to the desired temperature rapidly in the case of the large heat load while the increase of the size of the heating system being suppressed.

摘要： PROBLEM TO BE SOLVED: To prevent heating of an empty heat exchanger 3 even if a user turns ON a power source when he forgets to open a main cock after he drains it by starting a normal operation after a water flow sensor mounted at a water supply tube senses water flow without initial heat insulating operation in starting operation. SOLUTION: When an operation is started, whether water flow sensing or burner ignition has conducted so far or not is decided. If it is first time, whether there is an output of a water flow sensor 6 or not is checked. Here, when a hot water supply cock 9 is turned so that the sensor 6 senses the water flow, a burner 2 is ignited. When the cock 9 is closed, the water flow is not detected, and combustion of the burner 2 is stopped. Accordingly, if a power switch is turned ON while a user remains closed at the cock 9, no water in the water supply tube is sensed by the sensor 6, start of reheating operation of the apparatus is stopped, thereby preventing heating of an empty heat exchanger 3.

摘要： PROBLEM TO BE SOLVED: To provide a gas water heater in which rise time of hot water temperature is made relatively shorter without using a return pipe. SOLUTION: This water heater 1 intermittently ignites a gas burner 21 even if a passing flow quantity detected by a flow sensor 24 is a predetermined value or less. The timing for igniting the gas burner 21 is determined based on the hot water temperature near the outlet of a heat exchanger 22 detected by a heating temperature sensor 25 and hot-water feed temperature set at a temperature setting part 32 provided in a remote control device 30. By this operation, even if no water is fed to the water heater 1, the temperature of hot water in the heat exchanger 22 is kept at a relatively high temperature so that if hot water is delivered from the apparatus 1, hot water of a predetermined temperature can be supplied without delay.

摘要： PROBLEM TO BE SOLVED: To provide a hot-water supplier which restrains the danger of scalding by reducing the amount of discharged hot-water when a discharged hot-water temperature is higher than an expected value. SOLUTION: Water, introduced from an external source, is heated by a heat exchanger 22 while the temperature of the heated hot-water is detected by a discharging hot-water temperature detector 27 and is sent out of a hot-water discharging port 12. The heating amount in the heat exchanger 22 is controlled so that the temperature, detected by the discharging hot-water temperature detector 27, is kept at a temperature, set by a temperature setting unit 32. A discharging hot-water control valve 28 is provided near the hot-water discharging port 12 and when a detecting temperature, detected by the discharging hot-water temperature detector 27, becomes higher by a predetermined value or more than a set temperature, set by the temperature setting unit 32, the discharging hot-water control valve 28 is closed. Accordingly, the discharging of hot-water, whose temperature is increased to a high temperature abnormally, through the hot-water discharging port 12 can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide an instantaneous type gas water heater in which rise time it takes for hot water from the start of delivery thereof to reach a desired temperature even if the apparatus has been left out of operation for a long period of time. SOLUTION: For starting a water heater 1, a preheating is effected. In the preheating, a gas burner 21 is ignited for a required time period so that the apparatus is maintained in such a condition that hot water can be delivered. The heating time period is determined in such a way that amounts of heat required for heating water introduced into a heat exchanger 22 to a target temperature to send it out is obtained based on the temperature differences between a target temperature set by means of a temperature setting part 32 and temperatures sensed by a feed water temperature sensor 23 and based on the amounts of heat and heating capacity of the gas burner 21.

摘要： PURPOSE:To prevent a user from getting burned even if the user does not know how to operate a bathroom operation panel, by controlling the hot-water supply temperature according only to the set temperature while a human body sensor outputs detection signals. CONSTITUTION:A bathroom operation panel 2 is provided with a hot-water tap supply temperature setting device 4 by which temperature of hot-water supplied from a hot-water faucet is set, a bathtub temperature setting device 6 by which temperature of hot-water supplied to a bathtub is set, an indicator 9 on which both set temperatures are indicated in two rows, and in addition, a human body sensor 7 which detects the fact that a person enters a bathroom. When the human body sensor 7 detects the fact that a person enters the bathroom, the upper limit of hot-water tap set temperature is set at 45 deg.C, for example, at the same time output of a hot-water tap set temperature from a kitchen operation panel is cut off. When the present set temperature is not lower than the upper limit, the set temperature is forcibly revised to 45 deg.C, and set temperature from the bathroom operation panel 2 is limited to 45 deg.C or lower. Temperatures and characters of 'preference' as well are indicated on the indicator 9.
