How Long to Heat Pool with Heat Pump?
Heat pumps have quickly become the preferred water temperature control solution for swimming pools. With energy use and its subsequent influence on the environment becoming the main concern for users, the most efficient and reliable intelligent control systems are in high demand. Inverter swimming pool heat pumps are smart pool products with revolutionary new technology, and they have recently become more widely adopted due to their superior energy efficiency. But how long does it take to heat the water to a comfortable temperature? Let's see what factors will affect how quickly a pool heat pump can heat the pool water.
5 Factors Affecting the Heating Speed of Pool Heat Pumps
In general, the most common pool temperature for residential pools used for recreation ranges between 26°C and 28°C. The following five factors determine how quickly a swimming pool heat pump can raise the water temperature to 26°C or 28°C.
1. Climatic & Geographical Factors (mainly the effect of wind volume, ambient air temperature & humidity)
Heat pumps operate most efficiently at temperatures above 10°C. However, at temperatures below 10°C, heat pumps are less effective. Due to this, pool owners who live in colder climates must operate the inverter heat pump for a longer time to heat the pool. It is decisive to consider the local weather before investing in a heat pump, especially during the cooler months. Because the heat pump for the swimming pool takes heat from the air rather than generating it by itself, the run time depends on the weather conditions and surrounding circumstances.
2. Pool Cover (how fast your pool dissipates heat)
75% of swimming pool heat loss is due to evaporation. Uncovered pools will gain heat more slowly than covered pools. That is why swimming pool covers are so important. The pool cover can retain the heat in the swimming pool by minimizing evaporation as it acts as a barrier between the pool and the air. While reducing heat loss, a pool cover will also reduce heating costs and the time required to heat the pool.
3. Size of the Pool (how large is the body of water)
The heat pump will generally take longer to reach the desired water temperature for larger bodies of water, as a larger pool requires more energy to heat, resulting in a longer heating time. At this point, you need a more powerful heat pump to heat the pool quickly. Of course, the ambient temperature also has a significant impact.

4. Heat Pump Sizing (how much capacity is needed)
Pool owners often buy underpowered heat pumps to save money, but actually, underpowered heat pumps cost more to operate because you probably need more run time to heat your pool. And the heating will be less efficient the longer the run time is. Therefore, the size of an inverter pool heat pump significantly affects how long it runs. A more powerful heat pump produces more heat and requires less run time. It is more efficient and beneficial in the long run. So there is no need to select a small capacity for saving costs. Think Bigger is not a bad idea.
5. Water Temperature (both the current and the desired water temperatures)
The heating time required for heat pumps to a comfortable swimming temperature depends heavily on how cold the pool water is before heating starts. If the difference between the current and the desired water temperature is large, the longer it will take to run the pool heat pump. Therefore, the initial pool water temperature is vital for how long the heat pump will run.
How Fast Does Pool Heat Pump Work?
Provided you have considered all five factors above, a swimming pool heat pump typically takes 24 to 72 hours to heat a pool by 11°C.
How Long to Heat a Swimming Pool with a Heat Pump?
Heat pumps are capable of heating a pool by 11°C in 1 to 3 days. Most heat pumps operate at a maximum cold temperature of 10°C. But Fairland INVERX inverter heat pump for swimming pool functions in a broader temperature range, down to -15°C. Empowered by ground-breaking inverter heat pump system TurboSilence® inverter technology, the INVERX series deliver 4-season swimming fun to the world with the features of 3 times energy-saving and 15 times quieter operation. Soon, the pool heat pump manufacturer Fairland will launch a new addition to the INVERX series. The new INVERX series continues the simple and classic hexagonal design, perfectly combines natural elements and innovative technology, and raises energy efficiency to a higher standard.
