Heard about variable speed pool pumps but are not certain how they work or if they are a good option for your pool?
Single Speed Pumps and how they work
Most pools have a single speed pump on them. This was the traditional pump used for the last decade or longer when installing a new pool . They run at a consistent speed (approx 3500 rpm) and can be expensive to operate.
A Two-Speed pump is just that. They have two speeds – a high speed and low speed. They are a bit less expensive if you run them on the low speed.
With a two speed pump you can run the pump on low speed the majority of the time however will need to switch to high speed if you want to vacuum, run your heater as these require more flow rate to work.
Both a single speed pump and a 2 speed pump run on what is called induction motors
Variable Speed Pumps
Variable speed pumps are the best option for your pool. Whether you are changing out an old pump, wanting to purchase something that is more efficient, or are purchasing a new pool and the variable speed pump is an upgrade. With a variable speed pump you can customize the RPM that you want the pump to run at to give you the best bang for your buck. In a nutshell you set the flow rate which will operate your system using the least amount of energy.
Variable speed pumps use a a permanent magnet motor. They run much cooler, quieter and typically will last longer. A huge benefit to the variable speed is that there is a digital display that shows you how many RPM’s the pump is running at. They are WAY more efficient than the one and two speed pumps.
I put a variable speed pump on my pool and my operating costs went way down. They say that the variable speed pump will pay for itself in 3 years in energy savings.
Doesn’t it make sense to spend a little more now to save more for years?
