초록 ▼

A compact instantaneous-type electric water heater for household and commercial use provides hot water at a rate of at least five gallons per minute and includes a plurality of individual heating chambers connected in series flow relationship between a cold water inlet and a hot water outlet. A metallic mixing coil is disposed in series between each adjacent pair of chambers to promote even heating. The chambers are provided with electric heating elements having a combined wattage of at least thirty-thousand (30,000) watts. The heating elements are energized by a flow switch only at the time hot water is demanded and are controlled by an adjustable thermostat which sets the outlet water temperature and by a high temperature safety switch limiting outlet water temperature should the thermostat fail. The heating elements are connected to the electrical utility system by contactor-type relays so that some of the heating elements are connected to the service side of the utility system while the others are connected to the building side of the system. An adjustable regulator is provided to assure that the water flow rate will not exceed the capacity of the heater to heat the water to a minimum acceptable level. The heater is enclosed in a sheet metal casing capable of being accomodated inside a standard wood wall between a pair of adjacent studs thereof.
