Pool Heat Pumps: How Temperature Affects Their Performance

At AquaComfort Solutions, we specialize in premium, durable, energy-efficient heat pumps that allow up to year-round enjoyment of backyard pools and spas. Our heat pumps utilize proprietary technology to extract free ambient heat for even, efficient pool water heating. This process is highly efficient yet also dependent on environmental temperatures. Do all heat pump brands work well in cold temperatures? Well, not exactly. Outside air temperatures impact operation and efficiency, especially for low-quality heat pumps. Here’s how to know you are getting the most energy-efficient, high-performing heat pump for your pool.

Understanding the Relationship Between Heat Pumps and Ambient Air

The core principle behind heat pumps is harnessing heat energy from the surrounding air. This heat is used to warm a refrigerant gas that then transfers its warmth to pool water via a heat exchanger.  Colder air temperatures mean less heat energy is available to harvest. Therefore, as the air becomes cooler, heat pump performance can decline incrementally. The opposite also holds true — pump efficiency increases gradually as the air warms.  This inverse correlation between ambient air and heat pump capacity governs all models but can differ between brands. Research your brand minimum temperature when searching for a new heat pump to make sure you maximize your swim season. While many heat pumps stop performing in outside temperatures lower than 55 degrees, an AquaComfort heat pump keeps working in temperatures as low as 40 degrees Fahrenheit.

Factoring in Ambient Air with Your Heat Pump

When determining an appropriate size heat pump for your pool, the average low temperature for your area is a key factor. There’s no need to invest in a greater size heat pump than your pool may require. We can assess your climate zone and seasonal shifts when advising proper pump sizing to ensure steady heat despite expected ambient drops.

Settings for Optimal Efficiency

Along with right-sizing, properly configuring your heat pump maximizes efficiency as temperatures fluctuate.  Set to run overnight on warmer evenings and cycle off midday when heat is abundant to conserve energy. A digital thermostat with timer functionality allows custom programming for efficiency. Keep runtimes brief but frequent for smaller heat losses and gains.  We provide full guidance on ideal settings for your unique system and environment. 

Additional Tips for Cold Conditions  

A few added measures further bolster heat pump effectiveness as the mercury falls.  Protect your pool from cold wind exposure, which makes pool heating harder. Using a pool cover is an excellent way to trap in the warmth you desire. Switching to lower pump speeds in fall and winter requires less heat and facilitates electric savings. Insulate above-ground plumbing to retain water warmth.  With some adjustments, even frigid temps won’t decimate your pump’s heating abilities.
