Review on Sand filter pump 4.0 m3/h Intex SX1500 / for pools up to 20 m3 / 26644 by Stanislaw Mlekodaj ᠌

In the middle lane, as practice has shown, a pool of 2.5 m3 does not heat up warmer than 23-24 degrees even in extreme heat and in the sun, which is not comfortable. Heating required. If you wake up to heat with electricity, then pay attention to the requirements of the heater for the flow rate. In heaters up to 3 kW (Intex, Bestway,) the minimum flow is 1 m3 / h - this pump will pull - it has 4 m3 / h, with a long route, dirty sand, etc. its performance will not be lower than the required minimum on the flow side of the heaters. However, these heaters are very low power and are suitable for pools up to 3 m3. - the heating rate is less than 1 g / h, i. E. for 12 hours somewhere by 10 g . which will be almost acceptable. (from 18 to 28 per night). However, with a larger volume or a desire to heat faster, more powerful heaters will be required - 6.9 kW, etc. They have a built-in flow sensor. The minimum requirements for the flow start from 4m3 / h - this pump will not pull. They won't work with him. Therefore, if you plan to use a heater, it is better to take a pump with a higher capacity. The next pump in the Intex line, 26646, has a capacity of 6 m3, which already fits into the flow requirements of almost all heaters.
