What temperature will a pool heat pump stop heating?

The temperature at which a swimming pool heat pump stops heating will vary depending on the specific heat pump model and its specifications, as well as the ambient outdoor temperature.

On average, most pool heat pumps are designed to operate efficiently within a temperature range of around 50°F (10°C) to 95°F (35°C) outdoor air temperatures. However, the actual upper limit for heating may be different for different models.

As the outdoor temperature drops below the recommended range, the heat pump's efficiency decreases, and its heating capacity may become limited. At extremely low outdoor temperatures, the heat pump may not be able to extract sufficient heat from the air and may eventually shut down to prevent damage.

Similarly, if the outdoor temperature exceeds the recommended range, the heat pump may experience reduced performance or may even stop heating to protect its internal components from overheating.

To ensure optimal performance and longevity, it is important to consult the manufacturer's specifications for the specific pool heat pump model to determine its recommended operating temperature range and any limitations based on outdoor ambient temperatures.
