Understanding Pool Heat Pumps
Before diving into how long they last, it’s important to understand how pool heat pumps operate.
How Pool Heat Pumps Work
Unlike traditional pool heaters that generate heat through combustion, a pool heat pump “harvests” heat from the surrounding air. The process involves:
- A fan draws in ambient air over the evaporator coil.
- The refrigerant in the coil absorbs heat from the air.
- The heated refrigerant is compressed, increasing its temperature.
- It then transfers heat to the pool water circulating through the condenser.
- Finally, the heated water returns to the pool.
This method is highly energy-efficient and environmentally friendly, especially in moderate climates where temperatures rarely fall below 45°F (7°C).
Types of Pool Heat Pumps
There are two major types of pool heat pumps you may encounter:
- Electric Resistance Heat Pumps: These are less common and typically not as efficient as modern systems.
- Heat Pumps with Compressors (Common Type): These are the most popular and include both air-source and geothermal models.
The type you choose can significantly affect the heat pump’s performance and long-term durability.
How Long Do Pool Heat Pumps Typically Last?
The average lifespan of a pool heat pump ranges from 10 to 15 years, depending on various conditions. While this is longer than the typical 5–7 year expectancy of gas pool heaters, proper care can push that limit even further. Let’s break it down further with a chart illustrating typical lifespans based on brand and quality.
