Pool Heaters Repair

Enough Warmth  
Be sure that outside temperature is warm enough to provide heat. Around 50° F, heat pumps won’t heat at all, and the coil may develop ice. When outside temps are 50-70°, heating is much slower than when it is 70-90° outside. Direct sun hitting the areas around your heat pump also helps increase warmth. The panel may display a low temperature error code or message, when it is close to too cold to operate. 

Enough Time 
Be sure that your pool pump is running long enough each day (on high speed), and during the warm part of the day, to allow the heat pump sufficient time to heat the water. Especially for pools that don’t use a solar cover during cool nights, you may need 12 hours of pump run time to overcome heat loss, and maintain water temperatures. 

Enough Water Flow  
Like other pool heaters, pool heat pumps require a certain amount of water flowing through it for proper heat transfer. If the water is flowing too slowly, it simply won’t turn on. Be sure that the water level in the pool is correct, the filter and baskets are clean, and the pump running fully primed, to provide enough water flow to keep the heater pressure switch and/or flow switch in the closed position. The heater panel may display FLO as an error code, when water flow is insufficient. 

Enough Air Flow 
Even more than gas heaters, heat pumps require large amounts of air flowing over the coil. The coils can become clogged on the outside with dirt and debris, which restricts the air flow coming into the unit. Overhanging branches or eaves restrict the air flow coming out of the unit. Be sure that air flow into and around the heat pump is optimum, and not reduced by trees, bushes and weeds, or by walls, fences and roof overhangs. Both incoming and outgoing air flow is important for the most heat gain from a heat pump pool heater. The heater panel may display OH as an error code, when air flow is insufficient. 

Enough Refrigerant 
A refrigerant gas like Freon is used to generate the heat as it is compressed by the heat pump compressor. Although not common, over time small amounts of the gas can leak out. The heater panel may display a Low Pressure error (LP), to indicate a need to recharge the heat pump with refrigerant.
