Reduce Research Time by Answering These Simple Questions

We know your time is valuable, so we are here to help you get the unit you need. Just answer these questions to find out what model you need.

• Do you have an in-ground or above-ground pool? – Not all pumps are fit for both models as pools 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.

  The models that can easily adapt to any type of pool are FibroPool FH120, Pentair UltraTemp 460932, FibroHeat FH055, AquaPro PRO1100, and Raypak 013331 R8350TIE.

• What are the dimensions of your pool? – The heating potential represents the extent of heat the pump can supply and it’s measured in BTUs. One BTU can augment the temperature of one lb. of water by 1 degree Fahrenheit. So, the more BTUs, the prompter the heating process. However, when you determine how many BTUs you need, you have to also take into account the dimensions of the pool and the temperature rise.
• Do you want to cut power expenses? – The COP tells you how performant the unit is in terms of power use. With a simple method of calculation (energy output – the heat created by the pump – divided by the energy input to the pump) you can find out how much the electricity bill will increase. The result of this formula is the COP, and the higher it is, the more effective the unit. For every unit of energy input, the pump delivers 1 x COP heat energy. Now based on what we’ve said, let’s take for example one of the models we’ve presented and make a fast estimation.

  The models with the highest COP are Pentair UltraTemp 460932, AquaPro PRO1100, and Jandy Zodiac JE2000T – 6.0. This means that for every unit of energy they consume, there are produced 6.0 units of energy.

• How Important is the heat exchanger? – Its main purpose is to warm the water that passes through. After this action, the water it’s reintroduced into the pool. This operation is just a small part of the entire procedure and it continues until the total volume of water gets to the preferred temperature. It may be made from various metals including nickel and titanium. The quality of the material adds more toughness to the unit and increases its corrosion resistance.

  All the models we’ve selected feature a titanium component, which makes them rust-resistant when they get in contact with water. Additionally, this type of exchanger is proper for both salt and freshwater pools.

• Do you care about the natural world? – The models that use an R410-A refrigerant are made with the natural world in mind. 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.

• How important is the compressor? – There are two types of compressors, reciprocal and scroll. The reciprocal compressors are less used because they are outdated and not quite efficient. Conversely, the scroll compressors have become more popular because they have a condensed design and are much more performant.

  All the models from our comparison table use the innovative scroll compressor.

• Do you want the company to stand behind the product? – We paid special attention to the warranty of the selected products, this being proof that manufacturers are confident about the robustness of their products. To generate consumer confidence, a product has to be covered by a generous assurance.

  Pentair UltraTemp 460932 comes with the lengthiest service contract, 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 pool. They work slightly differently, but the final purpose is the same, that is to extend the swimming season. To better understand how they work and how exactly they differentiate, we will outline their main characteristics.

• Heat pumps: you may think that they supply heat, but this is not quite true. Using energy, they drag heat from the air, then compress it, and finally, release it in the water. The heat is circulated all through the pool. On the whole, these units are inexpensive to operate, even though you have to pay more money to purchase them. The trick with them is that they aren’t the best solution when the air temperature is too low as they require more power to run. Nevertheless, they are hard-wearing and ecologically friendly because they don’t pollute nature with all sorts of gases.
• Gas heaters: they are more prompt, as they can warm the water very fast. Consequently, they are ideal for pools that aren’t used regularly. However, it seems that their popularity has decreased significantly in the last few years. The reason is quite simple: they use propane or natural gas. This doesn’t make them an eco-friendly option for all those who care about the planet. In what concerns the price, they cost less than $1,500 but they aren’t cheap to operate and they aren’t energy efficient.
• Electric heaters 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 as professional help is usually needed. The main gain of this type of system is that is more inexpensive, the priciest models being under $2,000. Also, they are an ecological substitute if that’s what you’re looking for.
• Solar heaters: they have to be mounted on the roof of the house for best results and they are ideal for sunny areas. Using solar panels that yield the sun’s heat, these units warm the water in your pool through a pump. They are a green solution because they don’t emit any harmful gasses. Plus, they are hard-wearing, easy to install, and don’t require maintenance. But there are some drawbacks. Firstly, they are very pricey, with some models being priced at $3,500 – $4,000. Secondly, they require time to heat the pool. Thirdly, they got energy from the sun, so they need continuous sun exposure to operate.
