Abstract: A water heater includes a burner, a heat exchanger, a passing water quantity control unit, a temperature detection unit, and an operation control unit. The operation control unit performs the output hot water temperature control by configuring the passing water quantity control unit to have a predetermined passing water quantity that is further restricted compared with a predetermined water quantity, and upon confirmation that a predetermined release condition of the passing water restriction is satisfied, executes the passing water control in which the passing water quantity is returned back to the predetermined water quantity by gradually releasing the passing water restriction, and the operation control unit, when a predetermined undershoot factor of the detected temperature is confirmed while the passing water quantity is returned back to the predetermined water quantity, temporarily stops the release of the restriction of the passing water quantity until the undershoot factor is resolved.

Abstract: A rich-lean burner includes an inner cylinder to which lean gas, which is a mixture of gas and combustion air, is supplied, and an outer cylinder that is coaxially disposed around the inner cylinder such that rich gas, which is a mixture of gas and combustion air, is supplied between the inner cylinder and the outer cylinder. A burner head, which has small holes and whose diameter decreases toward the leading end, is provided on an opening of the inner cylinder. The burner head is obtained by forming a perforated metal, in which the small holes are arranged in a zigzag manner, into a conical shape. An interval between each of the small holes is two to three times the diameter of the small holes. The total area of the small holes is larger than the area of an upper end opening of an upper inner cylinder.

Abstract: A water heater connectable to an external air supply and exhaust pipe includes a housing that houses a combustion device, a connecting portion, a first air supply and exhaust pipe, and a second air supply and exhaust pipe. The connecting portion includes an outer cylinder and an inner cylinder projecting upward from an upper surface of the housing. The first air supply and exhaust pipe and the second air supply and exhaust pipe are selectively connectable to the connecting portion. The first air supply and exhaust pipe is connectable to the connecting portion by interpolating a first air supply pipe into the outer cylinder and interpolating a first exhaust pipe into the inner cylinder, and the second air supply and exhaust pipe is connectable to the connecting portion by externally fitting a second air supply pipe onto the outer cylinder and interpolating a second exhaust pipe into the inner cylinder.

Abstract: An object is to provide a water heater mounting structure for mounting a case to a mounting surface via a support fitting component that is fixed to the mounting surface in a vertical direction. The case houses a burning device. On a back plate of the case, a lock-engagement fitting component is mounted. The lock-engagement fitting component has an upper plate portion and a lower plate portion. The upper plate portion is fixed to the back plate, and the lower plate portion is lock-engageable with the support fitting component from thereabove and has a dimension longer than the support fitting component in the left-right direction. The lower plate portion is lock-engaged with the support fitting component from thereabove to hang and support the case through the lock-engagement fitting component by the support fitting component.

Abstract: A combustion device includes a solenoid valve configured to open and close an inflow port and an additional solenoid valve configured to open and close a communication port selectively mountable at an upstream end of a distribution flow passage with a small number of nozzles. When the additional solenoid valve is mounted, a state of supplying a fuel gas to only a distribution flow passage with a large number of the nozzles by opening the solenoid valve and closing the additional solenoid valve and a state of supplying the fuel gas to two distribution flow passages by opening the solenoid valve and opening the additional solenoid valve are mutually switchable. When the additional solenoid valve is not mounted, a state of supplying the fuel gas to the two distribution flow passages by opening the solenoid valve and a state of not supplying the fuel gas are mutually switchable.

Abstract: The case of the water heater is composed of a box body having a rectangular shape in front view with a front face opened and a front cover having a shallower bottom and assembled on the front face of the box body. While rear side bent parts bent inward are each formed at front ends of left and right side plates of the box body, the front side bent parts bent inward are each formed at rear ends of left and right front side plates of the front cover and are abutted on the rear side bent parts in a state of being assembled to the box body. The inner bent parts folded backward are formed at inner end parts of the front side bent parts and are positioned on inner extension lines of the rear side bent parts in an assembled state.
