Abstract

An apparatus and method for measuring the efficiency of a heating system in which the temperature of the flue, or stack, is measured during a heating cycle and data collected to show the elapsed time and maximum temperature achieved. This data is compared to predetermined limits and if the elapsed time and/or the maximum temperature exceeds the predetermined limits, an error message is generated that may be video, audio, and/or an email sent to a predetermined email address. Other statistics may be generated and temperature data from more than one heating cycle may be aggregated together.

Claims

1. An apparatus for measuring the efficiency of a heating system including a flue and thermostat providing a temperature adjustment signal, the apparatus comprising:

a temperature sensor thermally coupled to the flue and operative to measure the external temperature thereof and to provide a plurality temperature data;

a receiver coupled to said temperature sensor and operative to receive said plurality of temperature data; and

a temperature analysis module coupled to said receiver and operative to receive said plurality of temperature data and to store said plurality of temperature data and a plurality of time data, each of said plurality of time data associated with a corresponding one of said plurality of temperature data forming a plurality of time-temperature data, said temperature analysis module further operative to analyze said time-temperature with respect to a predetermined limit and to provide an error alarm in the event that the time-temperature data exceeds said predetermined limit.

2. The apparatus of claim 1 wherein said receiver is coupled to said temperature sensor via a hard-wired connection.

3. The apparatus of claim 1 wherein said temperature sensor includes a wireless transmitter to format and transmit said plurality of temperature data as a plurality of wireless temperature data and said receiver is coupled to said wireless transmitter and is operative to receive said plurality of wireless temperature data.

4. The apparatus of claim 1 wherein said transmitter includes a time generator to provide an individual time stamp associated with each of said plurality of temperature data.

5. The apparatus of claim 1 wherein said receiver includes a time generator to provide an individual time stamp associated with each of said plurality of temperature data.

6. The apparatus of claim 1 wherein said temperature analysis module includes a time generator to provide an individual time stamp associated with each of said plurality of temperature data.

7. The apparatus of claim 1 wherein said temperature analysis module includes a processor operative to perform calculations and to manipulate said time-temperature data.

8. The apparatus of claim 1 wherein said processor is operative to perform statistical analysis.

9. The apparatus of claim 8, wherein the statistical analysis includes finding a mean and standard deviation.

10. The apparatus of claim 7, wherein said processor is operative to compare said a portion of said plurality time-temperature data to said predetermined limit to find if said portion of said plurality of time-temperature data exceeds said predetermined limit.

11. The apparatus of claim 1 further including a display device coupled to said temperature analysis module and operative to display said time-temperature data.

12. The apparatus of claim 1, wherein said error alarm includes a visual alarm.

13. The apparatus of claim 1, wherein said error alarm includes an audio alarm.

14. The apparatus of claim 1, wherein said error alarm includes generating an email and sending said email to a predetermined email address.

15. The apparatus of claim 1 wherein said temperature sensor directly senses the temperature of the stack.

16. The apparatus of claim 1 wherein said temperature sensor indirectly senses the temperature of the stack.

17. The apparatus of claim 16 wherein said indirect measurement includes measuring infrared emissions from the stack.

18. The apparatus of claim 7, wherein said processor is a microprocessor.

19. The apparatus of claim 1, wherein said temperature sensor is coupled to the thermostat and is responsive to said temperature adjustment signal to begin to provide a plurality temperature data;

20. The apparatus of claim 1 wherein said receiver is coupled to said thermostat and coupled to said temperature sensor and is responsive to said temperature adjustment signal operative to begin receive said plurality of temperature data.

21. The apparatus of claim 1 wherein said temperature analysis module is coupled to said thermostat and coupled to said receiver and is responsive to said temperature adjustment signal to begin to receive said plurality of temperature data and to store said plurality of temperature data and a plurality of time data, each of said plurality of time data associated with a corresponding one of said plurality of temperature data forming a plurality of time-temperature data, said temperature analysis module further operative to analyze said time-temperature with respect to a predetermined limit and to provide an error alarm in the event that the time-temperature data exceeds said predetermined limit.

22. A method for measuring the efficiency of a heating system including a flue and thermostat. The method comprising:

(a) detecting the heating system turning on;

(b) sensing the temperature of the flue and providing temperature data;

(c) recording the temperature data and a time data associated with said temperature data to form time-temperature data;

(d) detecting the maximum temperature of the flue;

(e) recording the maximum temperature;

(f) determining the elapsed time from the heating system turning on until the maximum temperature was reached;

(g) recording the elapsed time associated with the maximum temperature;

(h) comparing the elapsed time and maximum temperature with a predetermined limit;

(j) in the event that the elapsed time, the maximum temperature, or both exceed the predetermined limit, record the maximum temperature and elapsed time in a not-in-limit memory and master storage memory;

(k) compare the number of entries in the not-in-limit memory and compare to a predetermined limit;

(l) in the event that the number of entries in the not-in-limit memory exceeds the predetermined limit, generate an error signal; and

(m) in the event that neither the elapsed time or the maximum temperature exceed the predetermined limit, record the maximum temperature and elapsed time in a in-limit memory and master storage memory.

23. The method of claim 22, wherein the error signal is an audio alarm.

24. The method of claim 22, wherein the error signal is a video alarm.

25. The method of claim 22, wherein the error signal is an email that is generated and sent to predetermined email address.

26. The method of claim 22 repeating steps (a)-(m).
