Pool Heat Pump

Pool Heat Pump Guide

There are many things you need to consider when trying to extend the number of days you can enjoy your pool, and a pool heat pump is just one of them. Although you might think that these products are pretty similar, many variances make the good ones stand out, and the sub-par worth avoiding. 


More energy efficient than a lot of gas heaters, they are a popular choice, but it is important to know what the best are capable of. This is why we have created the following buyer’s guide.

What To Look For In A Pool Heat Pump

Easy Installation

There are different types of pool heat pumps to choose from and some are easier to install than others. Anyone that knows a bit about pool maintenance might want to tackle this themselves but otherwise, installing a pool heat pump isn’t always simple.

You can pay for a professional to do the hard work, particularly if there are plumbing and electrical hook-ups involved.

Quiet Operation

If you have ever sat beside your pool, enjoying the relaxing warmth of the sun, only to have a noisy pool heat pump start to hum, you’ll know how much it can kill the mood.

This is not the case with a lot of the high-end products that despite having a high output, manage to operate quietly.

Energy Efficiency

A pool heat pump will have to work harder to heat larger bodies of water but when you buy the right fit, it still needs to be energy efficient. A lot will depend on your desired temperature and the starting temp of the water.

The cold it is, the harder it will have to work to bring it up to the temperature you need. This is going to cost more but it can be manageable if the product is energy efficient. 


This is going to be even more important if you have a saltwater pool but chlorine can also leave its mark and cause a pool heat pump to deteriorate if you don’t buy a durable product.

When the inner parts have adequate protection, the unit should last a long time. Just make sure the heat exchanger is known for being durable (titanium is always good) as this is often a reason for some products to not last so long. 


Although most pool heat pumps are hard wearing and well-built, even buying from a reputable company can leave you with a product that is faulty or doesn’t work as well after a while. The best way to protect your purchase is by buying a product with a lengthy warranty.


The size of your pool is a major factor in your decision. The pool heat pump needs to be capable of heating whatever you have in your backyard so make sure you find out the measurement before you purchase a heat pump.

If it does not have the output capability then you will find it makes barely any difference to the temperature. 

Pool Heat Pump Gas Vs Electric

These are the two choices you have to consider and both of them have their benefits. The main plus point for gas is that they are cheaper to run, especially when the temp drops lower than 55 degrees. This is where an electric pool heat pump will have to work a lot harder.

If you need to pay for a direct route to the gas line then you might find it difficult to install and it can rack up the price.

What Size Pool Heat Pump Do I Need?

The required output of the pump is dependant on the size of your pool. If you use a pool cover then it might not need such a high output but as a general rule, anything up to 10,000 gallons will need around 50,000 BTU, a pool of 20,000 gallons will require 110,000 BTU in the colder months, and a 25,000-gallon pool will need 125,000 BTU’s.

Are Pool Heat Pumps Worth It?

Although the initial outlay can be higher than buying a heater, they are most efficient to run and will cost you less in the long run. They are often regarded as the most efficient method of heating a swimming pool.

When you buy the right spec for your pool they can work just as fast as other methods without the big hit in your bills. 

How Much Does A Pool Heat Pump Cost?

We recommend investing in a pool heat pump that is known for being better than the budget options. The problem with these tends to be longevity as they are not made with quality materials to keep the cost down.

If you want a pool heat pump that is cost-effective but is still capable of giving you plenty more days in the pool, you should look for products that start around $1,500 but the truly high-end products will cost north of $3,000.

When Quickly Can A Heat Pump Heat My Pool?

Because of the way they are designed, a pool heat pump is better for extending the hours and days you can use the device during the warmer months. 

This is why they are considered an excellent option for anyone who lives in a sunny or warm climate. If you want to keep the water warmer during the summer season or when it is coming to an end, they are the best option in terms of energy efficiency. Usually, they need between 1-3 days to heat the pool.

This varies depending on the model and the temperature of the air it has to work with.

How Warm Can A Pool Heat Pump Get My Pool?

A pool heat pump works better when the temperature is warmer, notably 50 degrees and above. If the air is warm, they can move the heat from the air and warm the water. 

Anything below 50 degrees F and it is not going to be able to warm the pool.
