Why does your heat pump for the pool suddenly freeze up?

heat pump for pool

During the cold winter season, some freezing ice on your pool heat pump often happens, But, When the whole pump is covered in ice, there is a concern to worry about because your device won’t function well and might be at risk of getting damaged.



Some reasons why heat pumps for pools freeze up in the winter


The most common reason that makes your pool heat pump freezes up is the lack of reasonable care and maintenance, this causes damage to the pump, which eventually leads to the pump freezing up.


Most pool heat pumps come with a defrost unit and the primary purpose of the defrost unit is to defrost most ice that might settle in the pump, in case of a wrong defrost unit, the device won’t warm ice crystals that freeze up in the pump.


As well as, a lower temperature in the evaporator fins and the dew temperature in ambient air causes condensation to be produced on the evaporating fin’s surface. When the temperature reaches 0 degrees Celsius, the ambient air will cause the condensation water to turn into ice.


Here are some more parts that will lead the damage to freeze-up of your heat pump for pool. Refrigerator charge problem, damage to the control board, the problem with the sensor, damaged evaporation coil, and wrong valve.

Freezing rain settles on the devices and turns into a frost situation and once the top part begins freezing, the rest will follow quickly. Another reason makes your pool heat pump is freezing up might be raining hailstone clog in the device, freezing this from the inside out.


If the swimming heat pump for the pool is leaking out, there is a busted tube that takes water out on the inside, and in the cold winter seasons, the action of water released will turn into frost and freeze up the device.

Very low freon pressure is a common challenge that causes when it’s too cold outside to heat your pool. Low pressure means no temperature, low refrigerant that will freeze up the evaporation coil, Most pool heat pumps work efficiently when the outside temperature is over 45F-50F. The high pressure causes low flowing water pressure meaning there isn’t enough water passing through the heat exchanger for the process of heat transference on the other hand. Sometimes the condition can be confused with a wrong valve that appears open but closed inside the tube.


Run the defrost function

Modern heat pump for pool feature a defrost cycle because they’re all prone to developing ice. The defrost cycle works by reversing the valve to air conditioning mode, which switches off the outdoor fan and turns the outdoor evaporator into a condenser. This warms the high-pressure refrigerant. When that circulates through the outdoor coil, it melts the ice.

Even older models tend to feature defrost settings, although they may use mechanical timers instead of convenient temperature sensors and control modules. If your heat pump is an older model and you’ve had difficulty running the defrost cycle, it may be time for an upgrade.
