Abstract

The present invention discloses a method for monitoring a heat burner by establishing a reading result of the consumption and/or consumption frequency of a liquid consumed by the heat burner (A), determining an environmental temperature and/or an efficacy temperature (B), and correlating said environmental temperature and/or efficacy temperature (B) with the consumption and/or consumption frequency reading result (A), and thereby determining whether an abnormal heat situation has occurred, and/or whether the burner is operating efficiently, and transmitting information of the heat situation and/or burner efficiency via means of telecommunication to a relevant receiver. The invention also discloses the use of the method for monitoring and/or controlling heat systems.

Claims

1. A method for monitoring a heat burner, comprising the steps of

establishing a reading result of the consumption and/or consumption frequency of a liquid consumed by the heat burner (A),

determining an environmental temperature and/or an efficacy temperature (B), and

correlating said environmental temperature and/or an efficacy temperature (B) with the consumption and/or consumption frequency reading result (A), and

determining whether an abnormal heat situation has occurred, and/or

whether the burner is operating efficiently, followed by

transmitting information of the heat situation and/or burner efficiency via means of telecommunication to a relevant receiver.

2. The method according to claim 1, wherein (A) is established by correlating said consumption and/or consumption frequency with a predetermined consumption and/or consumption frequency.

3. The method according to claim 1, wherein (B) is an indoor room temperature and/or an outdoor temperature and/or a hot water reservoir temperature and/or number of degree-days.

4. The method according to claim 1, further comprising the steps of

determining a plurality of pressure values in a suction pipe connecting said heat burner with a container of liquid during at least one cycle of suction and non-suction of the pipe (C),

determining a lowest pressure value and a highest pressure value in the suction pipe during the at least one cycle (D),

subtracting the lowest pressure value from the highest pressure value (E),

correlating said result to a predetermined liquid level value (F), and thereby

obtaining a reading result of the level of the liquid in said container (G),

correlating the result of at least one of the parameters of (C) to a predetermined value of said at least one parameter of (C),

optionally, repeating the above steps (C) to (G) at least twice.

6. The method according to claim 1, wherein the temperature of pipe water and/or the outdoor temperature of pipe water and/or the temperature of at least one radiator is determined.

11. The method according to claim 1, wherein the liquid is oil.

12. The method according to claim 1, wherein the pressure value in the suction pipe is determined by a pressure sensor.

13. The method according to claim 12, wherein the pressure sensor is a differential transmitter.

14. The method according to claim 11, wherein the pressure sensor is a T-piece sensor.

16. The method according to claim 12, wherein drift of temperature and non-linearity of the sensor is compensated for.

18. The method according to claim 1, wherein the time period between the determination of the first pressure value and the determination of the second value is within one cycle of the suction pipe.

22. The method according to claim 1, wherein an alarm is initiated at the rise of an abnormal situation.

23. The method according to claim 22, wherein initiation of the alarm is when the hot water temperature is decreasing below a predetermined value.

24. The method according to claim 22, wherein initiation of the alarm is when the indoor temperature is decreasing below a predetermined value.

25. The method according to claim 22, wherein initiation of the alarm is when the burner is consuming an increased amount of liquid compared to a predetermined value.

26. The method according to claim 22, wherein initiation of the alarm is when the burner is consuming a decreased amount of liquid compared to a predetermined value.

27. The method according to claim 22, wherein initiation of the alarm is when there is a power failure.

28. The method according to claim 22, wherein initiation of the alarm is when the parameters (A) as defined in claim 1 are changing.
