Abstract
A water heater comprising a tank adapted to hold water, a water outlet communicating with the tank, a water inlet communicating with the tank and communicable with the outlet independently of the tank, and a temperature responsive valve in the tank for permitting unrestricted communication of heated water in the tank with the water outlet when the water temperature in the tank is below a predetermined value, and for restricting communication of heated water in the tank with the water outlet when the water temperature in the tank is above the predetermined value.
Claims17
A water heater comprising
- a tank adapted to hold water,
- means forming a water outlet communicating with said tank,
- means forming a water inlet communicating with said tank and communicable with said outlet independently of said tank,
- heating means for heating water in said tank, and
- temperature responsive means in said tank for permitting unrestricted communication of heated water in said tank with said water outlet when the water temperature in said tank is below a predetermined value, and for restricting communication of heated water in said tank with said water outlet and providing communication of said inlet with said outlet independently of said tank when the water temperature in said tank is above said predetermined value.
A water heater comprising
- a tank;
- a hot water passage communicating with said tank;
- a cold water passage communicating with said tank;
- means forming a by-pass passage for providing communication between said cold water passage and said hot water passage;
- and
- temperature responsive valve means in said tank for restricting water flow through said hot water passage when the water temperature in said tank is above a predetermined value and for allowing water flow through said by-pass passage when the water temperature in said tank is above said predetermined value so that cold water from said cold water passage and hot water from said tank are mixed to reduce the temperature of water exiting said water heater through said hot water passage.
A water heater comprising
- a tank having therein an opening;
- a plug in said opening, said plug including a water outlet port, an intake port communicating with said tank, a hot water passage communicating between said intake port and said water outlet port, a water inlet port, a cold water passage communicating between said water inlet port and said tank, and a by-pass passage communicating between said cold water passage and said hot water passage;
- and
- temperature responsive valve means in said plug and in said tank for opening said intake port and closing said by-pass passage when the water temperature in said tank is below a first predetermined value, for opening said intake port and said by-pass passage when the water temperature in said tank is above said first predetermined value and below a second predetermined value, and for closing said intake port and opening said by-pass passage when the temperature in said tank is above said second predetermined value.
