This calculator gives you an assessment of how well you get the water filtered. The calculator is based on how much water (m3) you have in the pool and how big the filter and pump are. Your pool installer can tell you more about that. Here you will often see that too large a pump has been installed on older systems. If the system does not run optimally, do not despair. In the vast majority of cases, only a few small adjustments are needed before the system is optimized. We always recommend fitting a flow meter (equivalent to the speedometer in a car). Pt. we recommend FlowVis. Note that there may be conditions which make the quality of your filter system better than the calculator shows.


The pipe calculator is simple. When you have calculated the flow (in the filter/pump calculator) you key it in and you have the answer to how big the pipes should be. Pipes that are too small, give too much back pressure. Too much back pressure means too much power consumption on the pump. Simple calculator, but also important - we think.


Is a bit long-haired and requires a lot of information. But if you use it, you are sure that you have the right information to optimize your pool's energy. Briefly, the calculator shows the back pressure in meters / bar. The more back pressure, the bigger the pump you need to circulate the water and thus it has quite a big influence on power consumption. There are basic things that create back pressure. Let us mention a few here; if the pipes are too small, the pump will have to work overtime (=more power), 90 degree angles create back pressure due to the turbulence that is just after the angle. The distance from the technical room to the pool also has a great influence on the back pressure. The shorter the better. We recommend that the pump is below the water level, but be aware that the longer it is down, the greater the back pressure. In general, angles, t-pieces, valves and other pipe parts will create back pressure. But they are necessary, so try to use bends instead of angles, again use y-pieces instead of t-pieces, use 63mm instead. Pipe/hose instead of 50 mm. Not everything is possible, but give it a thought.


Gives you an answer to how much power you can save by switching to a 3-speed pump. The only information you need to have ready is; how many m3 of water are in your pool, the size (KW) of your current pump, how many months you use your pool and how many hours a day your pump runs (should run 24 hours!). The answer will be how many kroner you save annually.


Tells you how big the filter should be and how much water your pump should provide. Information you must enter: water volume (m3) in your pool. Turnover time and filter speed (explanation can be found in the calculator). We think this is the most important calculator!
