All heating systems, after a few years of operation, can have their share of problems. Because we have been in the heat pump business for so long, we have had the opportunity to help a lot of our customers when they notice their unit is not working properly. Here are some basic steps to check and see if its operating properly before calling a heat pump professional.
- Air temperature. As we all know, air-source heat pumps transfer heat from the air to your swimming pool. Therefore, they depend on the air temperature. A heat pump operates more efficiently in warmer air because more heat is present in higher temperatures. 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.
- Temperature difference. What is the temperature difference between the air entering your heat pump and the air exiting your heat pump? It 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 pump’s run time depends on your filtration pump’s operation.
- Evaporator coil obstructions. 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 will also increase your electric bill. Remove all leaves, pine needles, twigs, and other objects from the top and sides of your heat pump.
- Flow, Flow, Flow! Constant, sufficient water flow is needed by your heat pump to transfer heat from the refrigerant to your swimming pool. Insufficient water flow will not only lengthen your heating time, but will also cause damage to your heat pump’s internal components. To check your water flow, make sure the valves to your heat pump are completely open and that your filter is clean.
