a sensor connected to a heat transfer system to detect efficiency of the heat transfer system; and

a display electrically connected to the sensor and including a first and second light to indicate a current operating efficiency of the heat transfer system, the first light illuminating while the heat transfer system continues to operate when the data from the sensor indicates the heat transfer system is currently operating at a desired efficiency, the second light illuminating while the heat transfer system continues to operate when the data from the sensor indicates the heat transfer system is not currently operating at the desired efficiency.

2. The operational efficiency apparatus of claim 1 wherein the heat transfer system has a refrigerant system and the sensor is a pressure sensor for detecting pressure of the refrigerant system of the heat transfer system and the first light illuminates if the data from the pressure sensor indicates the refrigerant system is operating at a desired pressure and the second light illuminates if the pressure sensor indicates the refrigerant system is operating at an undesired pressure.

3. The operational efficiency apparatus of claim 2 wherein the second light only illuminates if the detected pressure is above a desired pressure range.

4. The operational efficiency apparatus of claim 2 wherein the second light is an LED which is illuminated to signify that the heat transfer system needs to be serviced.

5. The operation efficiency apparatus of claim 1 further comprising a housing, wherein the display comprises a light mounted on an exterior wall of the housing.

6. A pool heat pump apparatus comprising:

a housing defining an inner opening;

a compressor disposed within the inner opening and connected to a refrigerant system having a high pressure side and a low pressure side;

a heat exchanger disposed within the inner opening within which at least a portion of the refrigerant system is disposed for heating fluid entering at a fluid inlet and discharging the heated fluid at a fluid outlet;

at least one fan for circulating air through the apparatus; and

an operational efficiency apparatus connected to the pool heat pump apparatus and having a first sensor monitoring a pressure associated with the high pressure side of the refrigerant system on a first side of an expansion valve of the refrigerant system and a second sensor monitoring a pressure associated with the lower pressure side of the refrigerant system on a second side of the expansion valve, and the operational efficiency apparatus displaying on a display data relating to the efficiency of the operation of the pool heat pump apparatus, wherein the display is at least one light which the operational efficiency apparatus illuminates while the pool heat pump apparatus continues to operate to indicate that the operational efficiency apparatus has determined the refrigerant system is operating at an undesired pressure.

7. The pool heat pump apparatus of claim 6 wherein the first sensor is a first pressure sensor for monitoring operational efficiency of the pool heat pump apparatus.

8. The pool heat pump apparatus of claim 6 wherein the operational efficiency apparatus illuminates the at least one light to indicate that the operational efficiency apparatus has determined the refrigerant system is operating at a desired pressure.

9. The pool heat pump apparatus of claim 8 wherein the light of the display only illuminates if the detected pressure is outside of a desired pressure range.

10. The pool heat pump of claim 8 wherein the at least one light comprises two lights, a first of the two lights illuminates if the detected pressure is below a threshold value, the second of the two lights illuminates if the detected pressure is above the threshold value.

11. The pool heat pump apparatus of claim 8 wherein the at least one light is an LED which is illuminated to signify that the heat transfer system needs to be serviced.

12. The pool heat pump apparatus of claim 6 wherein the display includes a light that the operational efficiency apparatus illuminates if either the first or second sensor detect pressure outside of a desired range.

13. A pool heat pump apparatus comprising:

a pool heat pump housing defining an inner opening;

a compressor disposed within the inner opening and connected to a refrigerant system;

a heat exchanger disposed within the inner opening within which at least a portion of the refrigerant system is disposed for heating fluid entering at a fluid inlet and discharging the heated fluid at a fluid outlet;

at least one fan for circulating air through the apparatus; and

an operational efficiency indicator connected to the pool heat pump housing and providing a real-time indication of the operational efficiency of the pool heat pump, the operation efficiency indicator including:

at least one sensor for monitoring pressure associated with the apparatus; and

at least one light that illuminates on a real-time basis as the pool heat pump continues to operate to indicate when the operational efficiency of the pool heat pump apparatus is efficient operation such that service is not needed; and inefficient operation such that service is needed.

14. The apparatus of claim 13 wherein the at least one sensor comprises a first pressure sensor monitoring a pressure associated with a high pressure side of the refrigerant system and a second pressure sensor monitoring a pressure associated with a lower pressure side of the refrigerant system.

15. The apparatus of claim 13 wherein the at least one light is at least one LED capable of indicating on a real-time basis when the apparatus is operating efficiently by displaying a first color and/or indicating on a real-time basis when the apparatus is operating inefficiently by displaying a second color different than the first.
