A brewer, system and method for heating water and dispensing heated water for producing a brewed beverage The brewer includes a water reservoir with a heating element associated with the reservoir for heating water retained in the reservoir A brewing substance holder is associated with the reservoir for receiving heated water from the reservoir A temperature sensitive control valve is provided in communication with the reservoir for controllably dispensing heated water from the reservoir to the brewing substance holder The temperature sensitive control valve may be in the form of a passive control valve which uses a bimetallic, magnetic or other material which is responsive to heat The water is placed in the reservoir and heated The elevated temperature of the water will result in operating the heat sensitive control valve to open the control valve and allow water to pass from the reservoir to the brewing substance holder.

1. A brewer for heating water and combining the heated water with beverage making substance to produce a beverage, the brewer comprising: at least one reservoir for receiving water;a brewing substance holder positioned relative to the reservoir for receiving water therefrom for combining, in the holder, substance in the holder with water dispensed from the reservoir;a heating element cooperatively associated with the reservoir for heating water in the reservoir;a control valve communicating with the reservoir for controllably dispensing heated water from the reservoir, the controllable valve including at least one temperature sensitive material which is directly contacted by and directly mechanically responsive to the temperature of the water in the reservoir to operate the valve;wherein the reservoir heats water by means of the heating element to a temperature which causes the control valve to at least partially open in response to the temperature of the water contacting at least a portion of the control valve and dispense water from the reservoir to the brewing substance holder; andin which the heating element includes a circuitous heating path in which water is fed from the reservoir to the heating path and returned to the reservoir to add heat energy in the circuitous path until a water temperature within a predetermined range of temperatures is achieved. 2. The brewer of claim 1, further comprising a first reservoir and a second reservoir, the control valve being positioned between the first and second reservoir with the second reservoir positioned proximate to the brewing substance holder for dispensing heated water from the second reservoir. 3. The brewer of claim 1, in which the control valve is a passive control valve. 4. The brewer of claim 1, in which the control valve includes a bimetallic portion which is directly and mechanically responsive to temperature, the bimetallic portion being in a normally closed position to prevent passage of water from the reservoir and operating to an open position when the temperature of the water in the reservoir is raised with a predetermined temperature range. 5. The brewer of claim 1, in which the control valve includes a magnetic portion which is responsive to temperature, the magnetic portion being in a normally closed position to prevent passage of water from the reservoir and operating to an open position when the water in the reservoir, which directly contacts the temperature sensitive material, is at a temperature within a predetermined temperature range. 6. The brewer of claim 1, in which the control valve is removable and replaceable with a second control valve. 7. The brewer as in claim 6 including a plurality of control valves, each control valve including a temperature sensitive material which is responsive to a different temperature or range of temperatures, wherein the use of a selected valve will allow brewing at a selected predetermined temperature range. 8. A process for producing a beverage using a beverage brewer, the brewer including at least one reservoir, a heating element cooperatively associated with the reservoir for heating water in the reservoir, a brewing substance holder cooperatively associated with the reservoir for receiving water from the reservoir and combining, in the holder, substance in the holder with water dispensed from the reservoir, and a passive temperature sensitive control valve communicating with the reservoir to control the flow of water out from the reservoir, the control valve including at least one temperature sensitive material which is directly contacted by the water in the reservoir to operate the valve an directly mechanically responsive to the temperature of the water contacting it, the method comprising: placing water into the reservoir;activating the heating element to heat water in the reservoir;adding heat energy through the heating element to water in the reservoir until a temperature within a predetermined temperature range is achieved;operating the passive heat sensitive control valve upon achieving a temperature associated with the control valve in response to the temperature of the water directly contacting at least a portion of the temperature sensitive material;dispensing water from the reservoir for dispensing into the beverage substance holder;combining the substance retained in the holder with the heated water; anddispensing beverage from the holder into a container; andfurther including providing a circuitous heating path, the method further comprising: passing water from the reservoir through the circuitous heating path for return to the reservoir during the heating process. 9. The method of claim 8, further including providing two reservoirs, a first reservoir being positioned above a second reservoir with the passive, temperature sensitive control valve being positioned between the first and second reservoirs, the method further comprising: dispensing water from the first reservoir to the second reservoir to prevent continued heating of water after achieving a water temperature within a predetermined range of temperatures, dispensing water from the second reservoir to the brewing substance holder. 10. The method of claim 8, further including providing the passive temperature sensitive control valve in the form of a valve having at least a bimetallic portion, the method further comprising maintaining the control valve in a normally closed position, operating the control valve to an open condition when the temperature of the water in the reservoir is within a predetermined temperature range to open the valve and dispense water from the reservoir. 11. The method of claim 8, further including providing the passive temperature sensitive control valve in the form of a magnetic valve, the method further comprising maintaining the control valve in a normally closed position, operating the control valve upon reaching a water temperature within a predetermined temperature range to open and dispense water from the reservoir. 12. The method of claim 8, further including providing a plurality of control valves, each of the control valves including a temperature sensitive material which is responsive to a different temperature or range of temperatures, wherein the use of a selected valve will allow brewing within a predetermined temperature range, removing a control valve from the reservoir, replacing the control valve with a different control valve, wherein the different control valve has a different temperature range setting to facilitate brewing within a second predetermined temperature range.
