What Factors to Consider When Choosing a Heat Pump?

As you can see from the pool heat pump reviews above, there’s a wide variety of heat pumps available for all types of pools. However, in order to choose the best pool heat pump for you and your pool, there are some important factors you need to consider, such as:


It’s easy to get stuck on the initial cost of a pool heat pump, but efficiency is equally important because it gives you insight into its performance and the actual cost to run.

In fact, a pool heat pump’s efficiency will allow you to calculate its daily, monthly, and lifetime operating costs.

Heat Exchanger

The primary role of a heat exchanger is to transfer warmth from a condenser to the pool water. Traditional heat pumps utilize copper or Cupro-nickel heat exchangers due to their inexpensiveness and ability to efficiently transfer heat.

However, many heat pump manufacturers now use titanium heat exchangers. Although titanium exchanger tubing is more expensive, it’s also more durable and corrosion-resistant.


Heat pumps use compressors to condense refrigerant into hot gas, which is then used to heat the pool water. There are two types of compressors found on heat pumps: scroll and reciprocating.

Reciprocating compressors were once quite common due to their compact size and less expensive cost.

However, due to their limited efficiency, most manufacturers have replaced them with scroll compressors, which utilize metal scrolls instead of pistons to compress refrigerants. Scroll compressors are much more energy-efficient and have fewer moving parts, making them quieter, more durable, and less expensive to operate in the long run.

Overall Costs

Many pool owners only consider the purchase price when shopping for a heat pump and determining its cost, but the efficiency of a heat pump and its overall costs are even more important.

From installation and operating costs to maintenance and repairs, the overall cost of a heat pump will far exceed its purchase price in the long run and should be seriously considered when reading pool heat pump reviews and choosing the best one for your pool.


A warranty can help minimize repair costs and help save you money whenever a repair is needed. Most quality pool heat pumps come with a warranty, but not all warranties are created equal.

Therefore, it’s not only smart to choose a pool heat pump with a more extended warranty, but it’s important to read and understand the warranty as well.

A quality pool heat pump is a wise investment, but it’s also a big one. However, by considering these factors, understanding your needs, and giving the pool heat pump reviews above at least one more run-through, you’re guaranteed to pick the very best pool heat pump for you, your family, and your backyard oasis.

Pool Heat Pump Advantages & Disadvantages

Pool heat pumps utilize electricity to semi-passively heat your pool. While they’re often more expensive than gas, electric, or solar pool heaters, the clever engineering of pool heat pumps allows them to perform better than electric pool heat pumps and nearly as well as less efficient gas models, providing you with great performance and monthly savings.

Here’s a closer look at the pros and cons of this smart pool heating solution:


The best pool heat pump reviews always mention the energy efficiency of pool heat pumps and for a good reason. Heat pumps are extremely energy-efficient and inexpensive to operate. In fact, most pool owners report an average monthly savings of $50 to $100 when switching from a gas pool heater.

Year-round heating

Since water-source heat pumps don’t rely on the outside air temperature to operate, they’re more efficient and can also be used any time of year. This allows you to extend the swimming season and enjoy a comfortably warm pool well into the winter months.


Pool heat pumps may be pricey, but they’re also durable and made to perform for decades. In fact, most pool heat pumps are built to last for up to 20 years or longer.


Solar pool heaters are always mentioned when the topic of pools and eco-friendliness arises. However, pool heat pumps also utilize renewable energy to produce and transfer heat. They also don’t emit any harmful gases, making pool heat pumps and environmentally friendly pool heating solutions.

Purchase price

Whether you’re shopping for the absolute best pool heat pump or simply want a serviceable model that won’t let you down, you should be prepared to spend more upfront for a pool heat pump than any other type of pool heater. While the upfront cost of a pool heat pump is often quickly offset by lower operating costs, it’s certainly something to consider.

Dependent on nature

While many of today’s quality pool heat pumps are water-source and can be enjoyed year-round, some are air-sourced and not suitable for use during the colder winter months.

Take longer to heat

Unlike gas pool heaters, pool heat pumps take a while to heat up larger pools.


How does a pool heat pump work?

A pool heat pump utilizes electricity and ambient water or air temperature to perform an energy exchange and heat pool water. It’s similar to an air conditioner but works in reverse. Rather than directly using electricity to generate heat via a heating element, a pool heat pump uses electricity to move water or air over a refrigerated evaporator coil.

The coolant in the coil is heated and transferred to a compressor for further heating before passing through a condenser and exchanging heat with colder pool water.

Can a pool heat pump be used for any pool?

Pool heat pumps work great, but as you know from this guide and the swimming pool heat pump reviews above, they’re not an ideal solution for every pool.

Pool heat pumps generate approximately the same BTU output as small gas pool heaters, so they may not be ideal for some large in-ground pools.

Pool heat pumps also require a dedicated electrical line similar to that needed for a hot tub, which isn’t available for every home.

Since heat pumps work best in sunny, warm climates and should be installed in an area with direct sunlight, they’re also not ideal for pools with shaded backyards.

How do you determine the right size pool heat pump for your pool?

Many pool heat pump reviews only mention models with the highest BTU outputs because of their performance and higher price tags.

However, different pool sizes require different-sized pool heat pumps. Fortunately, you can determine the right size pool heat pump for your pool by performing a few basic calculations.

First, you’ll need the surface area of your pool, which can be roughly determined by measuring its length x width.

Once you know this, you can plug it into the following formula to get the proper BTU output needed per hour to successfully heat your pool: (surface area) x (water temp – air temp) x 12.

What’s better, a pool heat pump or a gas pool heater?

Gas pool heaters easily provide the highest BTU output, with many residential models generating up to 400,000 BTUs. This allows them to quickly heat up nearly any sized pool.

However, gas pool heaters are also less efficient and cost a pretty sum to run. In fact, running an average-sized 250,000 BTU gas pool heater is similar to having a dozen gas stoves running full blast.

Pool heat pumps, on the other hand, perform nearly as well as gas pool heaters but are much more energy-efficient, saving pool owners hundreds and even thousands of dollars each year. Although they cost more upfront and are slightly less powerful, their energy efficiency is hard to ignore.


If you’re one of the many pool owners who’ve read this entire guide in order to learn all about pool heat pumps and find the best one for their pool, you should give yourself a well-deserved pat on the back!

Why you might ask? Well, because you now know more than enough about pool heat pumps to pick the perfect one for you and your pool. Sure, you could spend hours more reading reviews and debating taking the financial plunge.

However, there’s nothing worse than taking a polar plunge into an ice-cold pool, so go ahead and use what you’ve learned to pick out a great pool heat pump today. They may be pricey, but your nerve endings and wallet will thank you in the end!
