What should I consider when choosing a pool pump?

Pool pumps are designed for a specific water flow over a certain distance. The rule is that all water should be filtered within a maximum of 4 hours. If you have a 4×8 pool with a pool depth of 1.5 m, the water depth will be 1.4 m. Then you calculate the total water volume 4x8x1.4 = 44.8 m3. If you divide that by four to find out the minimum pool flow rate the pool pump must handle: 44.8 / 4 = 11.2 m3.

The pool pump for a pool with a volume of 44.8 m3 should therefore be able to handle at least 11.2 m3. Next, you should look at the pool pump curves.

If the pool pump is 1 m above the water surface and 9 m from the skimmer, a KSE75 is sufficient according to the curve above. However, you need to take into account all elbow joints in the system. Each 90-degree bend adds about 0.5 m, which is why a KSE100, i.e., a 1 hp pool pump, is recommended for pools measuring 4×8 m with a depth of 1.5 m.

What types of pool pumps are there?

Just like pool heat pumps come as inverters, i.e., stepless models, there are also so-called VSP pumps with variable speed available on the market. By having a lower flow rate over a longer period, you save on electricity costs. The power is still available to the pump if you need to backwash the filter. The price of VSP pumps will pay off after 4-5 years of use, and it is important that the pump is of good quality.

Should the pool pump run 24/7?

The answer is no. Although filtration is good for the pool water, you should turn off the circulation pump overnight. The reason you want to turn off the pool pump is that you do not want to mix the water, especially if the water is warm and it is cold outside. This way, you cool the water down at night instead.
