The pump is the biggest electricity user in a pool because it runs for many hours every day. Most older pools have a single speed pump that always runs at full power, even when the water does not need it. A variable speed pump solves this problem.
Why does it use less power?
A pump's power draw drops sharply as its speed drops, far more than the reduction in speed itself. Running at low speed for longer moves roughly the same amount of water for much less electricity than running at full speed for fewer hours. A variable speed pump lets you choose the right speed for each task.
A speed for every task
- Daily filtration: low speed for long hours, which is most of the running time.
- Vacuuming and backwashing: higher speed for a short time.
- Waterfalls and fountains: medium or high speed depending on the look you want.
- Heating or cooling: a speed that matches the unit's requirements.
Benefits beyond electricity
- Quieter running, which matters if the plant room is near the seating area.
- Better filtration, as slower flow helps the filter catch finer particles.
- Longer equipment life thanks to less stress on the motor, plumbing and filter.
- Smart scheduling with built-in timers for different speeds at different times.
When is upgrading worth it?
- Your current pump is old or keeps failing and needs replacing anyway.
- The pool runs long hours every day all year.
- You have water features or systems that need different speeds.
- Pump noise bothers you in the seating area.
If your current pump is new and in excellent condition and the pool is lightly used, it may be better to wait until replacement is due.
Installation points
- Size it for the pool volume, pipe sizes and filter, not the biggest pump available.
- Program speeds and schedules after installation; without programming it saves nothing.
- Proper electrical installation with suitable protection.
- Check the filter and valves in the same visit, since blockages reduce the benefit.
Frequently asked questions
Does a variable speed pump suit any pool?
It suits most residential pools, but it must be sized for the pool volume and existing plumbing.
Do I need a new filter as well?
Usually not, but we inspect the filter in the same visit because a clogged filter hurts any pump.
How many hours should the pump run daily?
It depends on pool size, bather load and weather. We set the right schedule after an inspection.
