Swimming Pool Heat Pump not Heating
Every swimming pool heating system has its own problems, and heat pumps are no exception: we at Leomon have helped many clients solve their heat pump problems over the years. If you find that your heat pump isn't heating your pool, there are a few things you can do before hiring a heat pump professional to check it out.
1. Check that your heat pump has adequate water flow.
Without a constant, adequate flow of water, your heat pump can't transfer heat from the refrigerant to your pool. Insufficient water flow will not only prolong your heating time, but it can also damage the internal components of the heat pump. To check the water flow, make sure the heat pump valve is fully open and the filter is clean.
2. Keep your evaporator coil clear of all obstructions.
An air source heat pump transfers heat from the air to your swimming pool. If there is not enough air in and out, your heat pump will heat less efficiently. Not only will an inefficient heat pump heat your pool more slowly, it can also increase your electricity bill. Remove all leaves, pine needles, branches, and other objects from the top and sides of the heat pump.
3. Check the air temperature.
Likewise, an air source heat pump transfers heat from the air to your pool. Therefore, they depend on the air temperature. Because more heat is present at higher temperatures, heat pumps operate more efficiently in warmer air. Also, heat pumps operate less efficiently in cooler air and need to run longer to heat the pool.
4. Measure the air temperature difference (A(Delta) T ).
A(Delta) T is the temperature difference between the air entering the heat pump and the air leaving the heat pump. A(Delta) T should be measured between 9° to 12°F (5° to 7°C). If so, then your heat pump is running fine, and your heating failure is most likely due to the heat pump running out of time. Remember that the heat pump's run time depends on the filter pump's operation.
If you are still uncomfortable with the operation of your heat pump after you have performed these checks, please contact your licensed heat pump professional. Some questions are best left to professionals. For example, if the case requires replacement of electrical components or gas valves, don't attempt DIY repairs. This may cause an accident.
If you are not sure why your pool heater is failing, call a professional pool heater installer. It's a faster, safer, and more practical option, especially if you lack a technical and mechanical background. Once the installer or repairer has figured out what to do, you can request a quote to decide where you should start.
