Tip: Make the upfront investment for the more expensive pump and reap the savings down the track in reduced energy costs!

Ask the pool builder for a sharp price to upgrade to a variable speed pump when constructing your new pool, or drop down to your local pool shop to see one and understand the true savings to be made, while standard pumps are nearly a third of the price, their extra features and long-term energy savings often make variable pumps a much better option. Pool automation can also work closely with variable speed pumps to get the most efficiency!

There are a lot of reasons why you should get a variable speed pumps. That is why we have created a separate article for this. Check out this link for more information.

While this guide is primarily about variable speed pumps, it’s important to understand the alternatives. When considering a new pool or even replacing your existing pool pump, you're probably wondering which type pool pump will best meet your needs. Great question! Here are a few points to consider when choosing the right engergy efficient variable speed pool pump.

Single speed pumps are your traditional pool pump and have been in use for decades. Once turned on, it runs at a constant speed. These style of pumps are easily the best priced in the market but are heavily inefficient. Single speed pumps are known as the most expensive appliance in most Australian homes! Wow!

Fact: While also running at that high speed, comes noise These also have a tendency to be significantly louder than variable or even two-speed pumps.

Dual (or two speed) pumps are the middle of the range with pool pump efficiency, the two speeds can be manually chosen to suit the demand. Low speed would be for the daily operation of the pool, while high speed for more demanding requirements such as running a pool cleaner, backwashing or vacuuming the pool

The lower speed on a dual pump can save you a bit of electricity because you won’t always have to have your water moving at a high rate of circulation, but each application is different and many pools will have different hydraulic requirements, so the two presets may not be the best option, either too little or too much power, which defeats the principal.

Unlike the inefficient single and two-speed pumps, variable speed pumps allow the user to "adjust and set" the exact flow rate they need for their pool allowing them to capitalize on the golden rule of pool circulation: slower is better. Variable speed pumps are an entirely different product compared to their power-hungry cousins.

Having that control over your pumps performance and efficiency is a huge advantage to the operating costs and makes it a much more economical choice. while the variable speed pumps have only been out for a few years now, but they typically outclass both single and double speed pumps.

Tip: The facts are proven and the return on investment is significant! Check out this post where we compare the numbers in dollars and cents saved when using a variable speed pumps!

Because variable speed pumps offer a much wider array of settings, they allow you to run your pool at optimum speed or the lowest speed to get the job done. This, in turn, creates less friction on your piping, filter, and accessories allowing your pool to run at a much lower energy level, as well as, less wear and tear, saving you money and increasing the lifespan of your equipment. This type of customization also allows you to program your pump to take advantage of lower rates through your electricity company when you are on off peak hours.

Buying a variable-speed pump may also qualify you for government incentives such as reduced utility rates. Power companies sometimes offer rebates to entice you to reduce your power consumption by using energy-efficient appliances and making smart choices. Local government may also offer after purchase rebates!

Tip: Check your local power company’s website for rebate information before you buy a new pool pump. You may be eligible for rebates, incentives and further information from your local council about cutting energy usage around your home - https://www.energy.gov.au/rebates

These pumps are very advantageous when it comes to savings, but one of the biggest complaints about variable speed pumps is their tendency to be much more expensive than the other types. It is important to note that the lower operating costs of the variable speed pump will greatly outweigh the energy expenses averted, a variable pump can save you minimum $400.00 annually!

Fact: Having the right pool pump can save you more than $50 a month, so it’s definitely worthwhile seeking a good variable speed pool pump!

Variable speed pumps are more efficient than both the single and dual speed pumps as they cannot adjust to the applications and requirements of each pool. With these pumps outputting maximum power all the time, it means maximum energy consumption and maximum costs!

Water filtration performs best at slower rates, the slower you can pass the water via a filter with less turbulence, the better the quality of filtration. 90% of pool operation can happen at the slowest rate (ensuring turnover is still maintained) the benefit of having a variable speed pump is that is can be adjusted in real time to meet the 10% or more requirements. Typically, pool owners who switch to variable-speed pumps recover the cost of the pump in energy savings in less than two years.

Fact: By dialing down output when high power isn’t required allows variable speed pumps to use up to 90% less energy than fixed-speed pumps.

Programming variable speed pumps can also ensure that water features, cleaners, jets and accessories are still operational while saving power when not required.

Tip: If you’re looking to lower your power costs, replacing the pool pump with a variable speed option is so much easier than convincing your family to spend less time binge-watching their favorite TV series!

Single-speed and dual-speed pumps always operate at the preset programmed speed. And with higher speeds comes louder operating noise that can lead to be irritating guests and your neighbours.

However, a variable speed pool pump allows you to adjust the speed and power of the pump; thus, in turn, will also reduce your pump’s noise level, you can simply program a lower speed setting and the operation noise of the pump will also reduce creating a more enjoyable experience for all.

With a reduced noise this will also allow for quiet operation at night, during off-peak power, so you’ll save money, clean your pool, and avoid a confrontation with grumpy, sleep-deprived neighbors.

Fact: Variable-speed pumps can run as low as 600 RPM. The lower RPMs significantly reduce the operating noise of the motor, making the variable-speed pump a far quieter option than standard single-speed pumps!

As with anything in life, we have our own personal favorites, and when it comes to energy efficient variable speed pumps, the Water TechniX Pump Vortex ECO is hands down the winner for us! It's a fraction of the cost of other variable speed pumps with the exact same features and on top of that, it's covered by Mr Pool Man's bulletproof guarantee!

As many of the points above stated, its a smart change to a variable speed pump and that many eco pumps also have longer warranties, up to three years as standard for some brands, whereas many conventional pool pumps come with a standard one-year warranty. This offers some valuable piece of mind when investing in your backyard pool.

Tip: When choosing a pool pump, remember that the more stars on the label, the more efficient the pump.
