摘要： PROBLEM TO BE SOLVED: To eliminate duplicated piping when a bathroom heater/dryer is installed in bathroom or dressing room. SOLUTION: Water supply/discharge part 230 of a bathroom heater/dryer on the dressing room side comprises a water inlet 231, a water separation opening 232, a drain outlet 234, and a water combination opening 235. The water supply opening 231 and the water separation opening 232 are coupled with the drain outlet 234 and the water combination opening 235, respectively, through U-tubes 144, 145 and the hot water tube 146 of a heat exchanger 138 is coupled to the way of the U-tubes 144, 145. Water supply/discharge part of the bathroom heater/dryer on the bathroom side comprises a water inlet, and a drain outlet. Hot water piping from a heat source is coupled with the water inlet 231 and drain outlet 234 of the bathroom heater/dryer on the dressing room side while the water separation opening 232 and the water combination opening 235 are coupled with the water inlet and drain outlet of the bathroom heater/dryer on the bathroom side thus eliminating hot water piping for coupling the bathroom heater/dryer on the bathroom side with a heat source machine.

摘要： PROBLEM TO BE SOLVED: To provide a wind direction changing louver capable of efficiently supplying hot air and a bathroom heater/dryer using it. SOLUTION: The main body 9 of the wind direction changing louver 7 has a shape obtained by cutting out a part of a circular cylinder so as to have central angle of 120 deg. to 170 deg.. This louver 7 is rotated by a stepping motor 13 so that hot air can be supplies to a range of about 180 deg. from an air outlet port 3. Since the hot air is not supplied in a distributed manner, the velocity of hot air is not lowered and the hot air easily reach the lower part of the bathroom.

摘要： PROBLEM TO BE SOLVED: To provide a gas water heater to improve further safety. SOLUTION: A controller 9 of the gas water heater 1 predicts a supply hot water temperature T by a formula of Qg×H×η/100=ρ×(T-Ti)×W from a parameter, such as Qg being a gas flow rate (M3/s) per a unit time determined from the openings of a main gas solenoid valve 19 and a gas proportional valve 21, H being a gas heat generating rate (MJ/m3) of fuel gas, η being heat efficiency (%) of fuel gas, ρ being a water specific heat ratio (MJ/(kg. deg.C), Ti being an inflow water temperature ( deg.C) detected by an inflow water thermistor 15, W being a water flow rate (kg/s) per a unit time determined by a water sensor 13 and from the opening of a water flow control valve 33. When an absolute value of a difference between the predicted supply hot water temperature T and a supply hot water temperature To detected by a supply hot water thermistor 35 exceeds a certain value, operation of apparatuses is stopped.

摘要： PROBLEM TO BE SOLVED: To provide a method and a system for controlling hot water in which convenience of control is enhanced by making possible to regulate the flow rate of circulating hot water at the time of water filling operation. SOLUTION: The method and system for controlling hot water (2) circulating through heating terminals (6, 8) comprise a step and means (control section 30, test operation switch 44) for commanding or detecting water filling operation, and a step and means (control section 30) for differentiating the flow rate of hot water circulating through the heating terminals and a circulation passage (22) at the time of water filling operation from that at the time of steady operation. Since water filling operation is quickened and air purge function is enhanced, convenience of control is enhanced.
