Every swimming pool heating system has its share of problems, and heat pumps are no exception: over the years, we at AquaCal have helped many customers solve their heat pump problems. If you notice that your heat pump is not heating your swimming pool, there are a few things you can do before hiring a heat pump professional to check it.
- Check that your heat pump is getting sufficient water flow. Without constant, sufficient water flow, your heat pump cannot transfer heat from the refrigerant to your swimming pool. Insufficient water flow will not only lengthen your heating time, but also cause damage to your heat pumps internal components. To check your water flow, make sure the valves to your heat pump are completely open and that your filter is clean.
- Free your evaporator coil from all obstructions. Air-source heat pumps transfer heat from the air to your swimming pool. Without sufficient air inflow and outflow, your heat pump will heat less efficiently. An inefficient heat pump will not only heat your swimming pool more slowly, but also increase your electric bill. Remove all leaves, pine needles, twigs, and other objects from the top and sides of your heat pump.
- Check the air temperature. Again, air-source heat pumps transfer heat from the air to your swimming pool. They therefore depend on the air temperature. Because more heat is present in higher temperatures, a heat pump operates more efficiently in warmer air. Similarly, a heat pump operates less efficiently in cooler air and will need to run for a longer period of time in order to heat your swimming pool.
- Measure the air temperature difference (A(Delta)T). A(Delta)T is the temperature difference between the air entering your heat pump and the air exiting your heat pump. A(Delta)T should measure between 9° and 12°F (5° and 7°C). If it does, then your heat pump is operating normally, and your heating failure is most likely due to inadequate run time of the heat pump. Remember, your heat pumps run time depends on your filtration pumps operation.
If, after you have performed these checks, you still feel uncomfortable about your heat pumps operation, contact your licensed heat pump professional. Do you have any questions about your heat pumps operation? Leave a comment below or contact us directly at AquaCal. We would be happy to help you!
