Older model swimming pool pumps operate at a single, constant speed. If you replace your old pump with a variable-speed pump you can save money on energy costs. A new, exceptionally efficient variable-speed pump uses far less energy than a single-speed pump. Here’s why:
Today’s pool pumps are technologically advanced. While a single-speed pump moves water through your pool’s system at a constant rate of speed, a variable-speed pump can be adjusted to use less energy during parts of the pump cycle that don’t require as much water flow.
For instance, it takes more energy to circulate water through the system during cleaning than during heating and regular circulation. A single-speed pump pushes water through the system at the same rate for all of these tasks.
With a variable speed pump, you can slow the rate of energy used during the heating and circulation stages of the pool cycle. This type of pump runs at up to eight different speeds, adjusting its energy usage at different points in the cycle.
While a variable speed pump costs more initially, you can actually save up to 90 percent on energy costs over what you’re now paying to run your single-speed pool pump. Besides the energy savings, the cost of maintaining a variable-speed pump is less, since it isn’t constantly running at top speed and so experiences less wear and tear.
You could see a return on your investment in as little as one to two years after upgrading from a single-speed to a variable-speed pump. Some governments and local utilities also offer rebates for installing variable-speed pumps, just as they do for other energy-saving home improvements.
Works More Efficiently
As if that’s not enough, a variable speed pump actually works a lot better than a single-speed pump, giving you cleaner, clearer water. That’s because the water gets more thoroughly filtered when it’s routed through the system more slowly because the filter has more time to remove impurities.
On the other hand, single-speed pumps rush water through the filter at top speed, sending it back into the pool only a little cleaner than before it was filtered.
Runs More Quietly
Even if you run a variable-speed pump longer, you can still save thousands of dollars in energy costs. A variable-speed pump can even be run 24 hours a day and they are much quieter than traditional pumps, so you can run them overnight without creating too much noise.
Although, initially more expensive, variable-speed pumps will definitely save you money in future energy costs and pool maintenance, as well as giving you cleaner pool water. All of that makes them the best investment you can make for the future enjoyment of your swimming pool.
