For the last two years I have had my pool, it has really frustrated me that the water temperature (that decides if the heater should run) was very inaccurate. If the sun is out, it could be 5-10F different then what either the sensor in the Heat Pump thinks the water is, the sensor in the salt cell, or the temperature in an old fashion thermometer in the water.
The pool company says that the one I think is off is the most accurate and the rest are not very accurate. So, my pool says it is 87F right now, the heat pump says it is 80. The thermometer says 81, so I think that is probably the most accurate. That is a huge difference!
Anyways, I read the manual on my equipment and it says the temperature sensor should be installed with insulation around it (and 3Ē of the pipe) and painted white. I plan on bugging my pool builder (but it has been 2.5 years since they built the pool), but if they are no help, any suggestions for what I can use? Some link to something on amazon would be best (for insulating). I canít paint white if necessary, but would be nice if I donít have to.
