When home buyers are looking to purchase a home with a pool it is important to have all equipment checked as part of the home inspection. You want to make sure that all of the pool equipment is up to date and working properly. Each pool system is unique to that home. Pool companies offer a variety of pool styles and packages. Additionally, equipment packages such as heaters, salt systems, and variable speed pool pumps could be associated with the pool. The idea of a variable-speed pool pump is to save on your electric bill and keep the pool water flowing properly. What rpm to run the pool pump for 15K gallon pool? The RPM needed to turn over the water flow of a 15K gallon pool is going to vary based on the pool style.

Let’s take a look below at what it means to have a variable speed pump.

What Is A Variable Speed Pump

The purpose of a variable speed pool pump is to reduce the amount of energy needed to turn over your swimming pool water. In many cases, the homeowner or swimming pool technician will program the variable speed pool pump to adjust the RPMs during various times of the day. The maximum of 3,450 RPMs is adjusted and reduced throughout the various parts of the day. Every pool and pool situation is unique to each home.

Therefore, the schedule in which a variable speed pool pump runs is determined by the exposure to the sun. Also, how long the pool water is exposed to high heat temperatures. Your variable speed pool pump uses a fan-cooled magnetic motor to keep it from burning up while in use.

What Is The Best Schedule To Run My Pump And Save

There is no guaranteed best schedule to run your variable speed pool pump. The fact that you have a variable-speed pool pump allows you to save money on your energy bill. You will have what is called off-peak time frames and on-peak time frames. Those time frames are typically in unison with when the sun has risen and becomes the hottest part of the day. A typical off-peak schedule would be anything before or after 10 am to 2 pm.

To become energy efficient and push the flow of water through all systems attached to your pool, you will want an RPM rate of 3,450. Those systems such as salt systems, water features, and heaters or heat pumps will require an average RPM of 2,000 to be successful. However, a variable-speed pool pump can run half that speed for twice as long and filter the exact amount of water as a single-speed pool pump. If you can reduce your RPMs from 3,450 to 1,725, you can gain a percent savings of 75%.

How Do I Calculate My RPM Needs

Single-speed pool pumps are built to run at the same rate for less time. It is typically recommended that you run a single-speed pool pump for 6-8 hours. Here in Florida, it is likely that you will need to run your pool pump for 8-12 hours. Your variable-speed pool pump will need 8-12 hours to turn over the same amount of water in the time a single-speed motor can. Let’s take a look at the formulas to calculate this information.

  • turnover rate = gallons divided by flow rate divided by 60.
  • gallon per hour is calculated by dividing gallons (15,000) by the turnover rate.

How Much Does It Cost

The national average to install a variable speed pool pump ranges from $850 to $1,500. This depends on the manufacturer and labor costs. Every pool is unique and will require the correct variable speed pool pump in order to circulate the water flow at the necessary rate. Make sure to do your research as to the best variable speed pool pumps available.

Other Recommended Maintenance

Now that you have an idea about how your variable speed pool pump works to save money. It is a great idea to also understand what are some reasons for it to break down. For example, if your variable speed pool pump begins to leak, you would want to know how to repair it. As a homeowner, you might not have the time to call a swimming pool service technician to assist. So, being handy with your tools and making the repair is a great idea.

Next, if your swimming pool doesn’t have a cage around it, you might experience higher costs for pool maintenance. In Florida, a lot of homes have pool cages to help keep debris and animals out of the pool. If you do not have a pool cage around your pool, it is a great idea to look into getting one installed.
