About Products Ratings

By comparing the selected products, we have managed to classify them according to their performance and efficiency. All the 5 pool heat pumps were chosen after many hours of research, just to make sure they meet your expectations. The main purpose of the comparison chart is to help you find out important details about the products, including their size, type, warranty, and so on. Only after differentiating them, you will be able to choose a good heat pump for heating the water in your swimming pool. So, here is what stands behind our ratings.

  • Pool Type

  • Not all heat pumps are suitable for both inground and above ground pools because the swimming pools usually have different sizes and connection ports. Those units that work for both types of pools are more versatile from this point of view, but this is not necessarily a big advantage. Taking a look at our comparison chart, the only models that can easily adapt to any type of pool are the Raypak 013331 R8350TIE and the Pentair 460930, the first one having a restriction in what concerns the size of the inground pool. The others are suitable only for inground or above ground pools.

  • Heating Performance

  • The heating performance represents the amount of heat the pump can deliver and it’s measured in British Thermal Units or BTUs. One BTU can raise the temperature of one pound of water by 1 degree Fahrenheit. So, the more BTUs, the faster the heating process. However, when you determine how many BTUs you need for heating your swimming pool, you have to also consider the surface area of the pool and the temperature rise. Our first choice, the Raypak 013331 R8350TIE generates 130000 BTUs, while the last 2 models generate up to 70000 and 50000 BTUs.

  • Coefficient of Performance

  • The coefficient of performance tells you how performant is the pump in terms of energy use. With a simple method of calculation (energy output – which in this case is the heat created by the pump – divided by the energy input – which in this case is the energy input to the pump) you can find out how much the electricity bill will increase at the end of the month. The result of this formula is the COP, and the higher it is, the more efficient the heat pump. For every unit of energy input, the pump produces 1 x COP heat energy. Now based on what we’ve said, let’s take for example one of the 5 pumps and make a fast estimation. The Hayward HP21104T has a COP of 5.7, so this means that for every unit of energy it consumes, there are produced 5.7 units of energy. In comparison to all the other models from our chart, the one with the highest COP is the Jandy Zodiac JE2000T.

  • Heat Exchanger

  • The main purpose of a heat exchanger is to warm the water that passes through. After the water is warmed it’s reintroduced into the pool. This operation is just a small part of the entire working procedure of a pool heat pump and it continues until the entire water gets to the desired temperature. The heat exchanger may be made from various metals including nickel and titanium. The quality of the material adds more durability to the unit and increases its resistance to corrosion. All the models we’ve selected feature a titanium heat exchanger, which makes them rust resistant when they get in contact with water. Additionally, the titanium heat exchanger is suitable for both salt and freshwater swimming pools.

  • Compressor

  • There are two types of compressors, reciprocal and scroll. The reciprocal compressors are less used because they are outdated and not quite efficient. On the other hand, the scroll compressors have become more popular because they have a compact design and are much more performant. In consequence, all the pool heat pump from our comparison table use the innovative scroll compressor.

  • Refrigerant

  • The pool heat pumps that use a R410-A refrigerant are made with the environment in mind. According to the manufacturers, this type of refrigerant is a better choice in comparison to other refrigerants which are less efficient and more polluting. For this reason, we made sure that all the products selected have an eco-friendly R410-A refrigerant.

  • Warranty

  • We paid a special attention to the warranty of the selected products, this being a proof that manufacturers are confident about the durability of their products. In order to generate consumer confidence, a product has to be covered by a generous warranty. The Pentair 460930 comes with the longest warranty, but there’s one condition, you have to register the product and make proof of payment. Once you do this, you will be able to enjoy an extended warranty.

Pool Heating Systems Available

Besides the heat pumps, there are other types of systems that can warm the water in your swimming pool. They work slightly different, but the final purpose is the same, that is to extend the swimming season. Including the heat pumps, we can say that there are 4 pool heating systems you can choose from, the other 3 being electric heaters, gas heaters, and solar heaters. To better understand how they work and how exactly they differentiate, we will outline their main characteristics.

  • Heat Pumps

  • You may think that the heat pumps produce heat, but this is not quite true. Using electricity, they extract heat from the air, then compress it, and finally, they release it in the water. The heat produced is circulated all through the swimming pool. In general, the heat pumps are cheap to operate, even though you have to pay more money to purchase them. The trick with these pumps is that they aren’t the best solution when the air temperature is too low as they require more electricity to operate. However, they are very durable and environmentally friendly because they don’t pollute the environment with all sorts of gases.

  • Electric Heaters

  • As opposed to the heat pumps, the electric heaters use electricity to generate heat. In general, they are recommended for small pools because they tend to use a great amount of electricity to heat the water. Most models have a COP of 1.0. Installing them may be complicated and expensive and you may need the help of a professional. The main advantage of this type of pool heating system is that is cheaper in comparison to other types, the most expensive models being under $2000. Also, they are an eco-friendly alternative if that’s what you’re looking for.

  • Gas Heaters

  • The gas heaters are the best option in terms of promptitude, being able to warm the water very fast. For this reason, they are ideal for swimming pools that aren’t used regularly. However, it seems that their popularity has decreased significantly in the last years. The reason is quite simple: they use propane or natural gas. This makes them an eco-friendly option for all those who care about this planet. In what concerns the price, the gas heaters cost less than $1500 but they aren’t cheap to operate and they aren’t energy efficient.

  • Solar Heaters

  • The solar heaters have to be installed on the roof of the house for best results and they are ideal for sunny areas. Using solar panels that collect the sun’s heat, these heaters warm the water in your pool through a pool pump. They are a green solution because they don’t emit any harmful gasses. Also, they are very durable, easy to install, and don’t require maintenance. But there are some drawbacks. Firstly, they are very expensive, some models being priced at $3500 – $4000. Secondly, they require time to heat the swimming pool. Thirdly, they got energy from the sun, so they need constant sun in order to operate.

Top Brands to Go With

There are many heat pump brands on the market, but it seems that only some of them have managed to gain the customers’ trust. All well-known manufacturers offer you the advantage of buying reliable pumps that can efficiently heat the water without rising your electricity bills.
