Best Pool Heat Pumps

There is nothing more exciting than having a swimming pool in your backyard. Those moments of relaxation that you can enjoy in your own swimming pool cannot be compared to anything. However, in order to maintain your pool crystal clear, you need to pay attention to several things. It is necessary to find a way to heat your pump up when it starts to get cold outside. Without a doubt, a pool heat pump is one of the most popular pieces of equipment used to maintain a swimming pool in good condition. As compared to the solar pumps that directly generate heat, the heat pumps absorb heat from the air and transform it into your swimming pool water. This is a much more cost-effective pool heating solution.

Lucky for you, this is the right place to be. We spent more than 15 hours trying to find some of the best models on the market, and we finally did. In the matrix below, you will find 5 of the best pool heat pumps available in the current market.

What’s Behind our Ratings

best heat pumps

As you can see from the comparison chart above, there is a wide variety of pool pumps available for all types of pools. Since each one of the models above is equipped with a plethora of useful features, it’s recommended to compare them in order to find the one that meets your expectation. Keep on reading the following lines to learn more about the most important features that a poop pump should have.

  • Heat Exchanger

  • The heat exchanger plays an important role in this equation. It transfers heat from a condenser to the swimming pool’s water. They are so inexpensive because they have copper in their composition. Due to this mix of copper with nickel, they transfer heat more efficiently. However, if you are looking to purchase something else, you can take a look at the titanium heat exchangers. They are much more durable than the copper exchangers, but they are also more expensive.

  • Compressor

  • The compressor’s main purpose is to condense refrigerant into a high-pressure gas. There are two types of compressors on the market, such as the scroll and the reciprocating ones. While the scroll compressors use metal scrolls to compress refrigerant, the reciprocating ones utilize pistons to compress refrigerant. Once the reciprocating types were extremely popular, especially due to their compact size and inexpensive price. Unfortunately, due to the fact that they are not as efficient as the scroll ones, most manufacturers have replaced them with scroll compressors. They provide more efficiency and are less expensive than reciprocating compressors.

  • Digital display

  • If you are looking to purchase an advanced swimming pool pump, you will surely be impressed by a heat pump with digital display. An easy to read digital display is everything you need when it comes to innovative features. It is extremely useful, offering you detailed information about temperature, pressure and water flow.

  • Efficiency

  • There is nothing more important than the efficiency of a heat pump. This coefficient will give you a better understanding of your heart pump’s overall performance. The coefficient of performance (COP) is used to express the energy efficiency of various devices, including heat pumps, heaters and more other devices. In fact, this coefficient helps you measure the ratio of energy output to the energy input. The higher the efficiency and the COP, the lower the operating costs. Since there are so many models of pumps on the market, it is important to know that most of them come with a coefficient of performance that measures over 5.0. In simple terms, they are able to produce over five units of energy for every unit they consume. What you really need to understand is that not all pumps are created equally. Pumps with higher COPs are more expensive than heat pumps with a lower coefficient of efficiency. However, in the long run, you will spend more money on operating costs with a pump that has a lower COP.

Heat Pumps vs. Pool Heaters

pool heat pump vs. pool heater

Have you been thinking about buying a new swimming pool heat pump or pool heater, but it’s quite difficult to decide which one is the best? Before choosing a model it’s important to consider where you live. If you want your heat pump to work properly, you should live in an area with higher temperatures. Heat pumps work by drawing in outside air and transforming it into heat. The higher temperature, the more heat can convert into hot water. If you live in areas with cold climates, you might want to use a pool heater which can work anywhere, regardless the climate. A heat pump used in a cold climate requires more energy as compared to a pool heater which is more environmentally friendly in this situation. Furthermore, a heat pump is more expensive than a pool heater. However, if a pool pump works constantly, you will pay more than for a heater. If you are thinking about installing a pool heater, decide whether you want a gas or propane one. Also, it’s important to know that both electric heaters and pool pumps need electrical wiring to operate. This should also be included in the installation costs. To conclude, take note that a heat pump is much more efficient than a pool heater. Even if the costs are a bit higher, it is worth the investment.

Frequently Asked Questions

1What type of pool will a pool heat pump heat?
There are heat pumps for all types of pools, including above ground, in ground, concrete tile, or liner.

2 What is the most important quality in a pool heat pump?

3What are the down sides of a pool heat pump?
Pool heat pumps require a fan to work properly. The fan and the internal compressor make a noise, so it’s advisable to find a place where it will not disturb the neighbors.
