Above Ground Pool Heater Buying Guide:

Gas Vs. Solar Vs. Electric Heaters

A pool heat pump is an excellent way to keep the water in your pool warm, especially if you have to use it during the cold winter months. With the right pump, you will enjoy excellent heating costs, minus the excessive electrical costs associated with such tools. It does not matter whether its 6 am or 11 pm, a good pool heater should keep your water warm. 

The gas heaters are also excellent, but they are associated with various safety issues. Plus, you have to replace the gas regularly, which can be a costly affair.

There is no doubt that solar is an excellent source of energy because its affordable and readily available. The only costs associated with such an investment are investing in the panels and the cost of ensuring they operate at optimal levels. Various factors come into play when you want to use solar panels. For instance, during the cold summer months, using such a heater would not be practical. Why? Its because the amount of sunlight at such times is often low.

Factors to Consider When Shopping for Pool Heaters

So you are finally ready to get the above ground pool heater you have been eyeing. However, you have to consider some of the key factors before settling on a specific type for your needs. They include:

Fuel Used

You can classify heaters for your pool in relation to the type of fuel used for the water heating process. While most types are electric, people increasingly realize the benefits of solar types. The main drawback of such heaters is that they are not suitable for use during the summer months.

The gas types that function using propane or natural gas can function all year round but are associated with leakages. Plus, the electric types are also excellent but are associated with excessive electrical costs, especially if your pool is large.

Overall Pool Size

The size of the pool will determine the right capacity heater you should select for your pool. If you have a big swimming pool, consider going for the types with the “high capacity” metric on them. This means they are powerful tools you can use to warm large pools, such as those used for commercial applications. However, the “low capacity” types are suitable for residential swimming pools, such as most common above ground pools.

Installation Procedures

Usually, different pool brands have varying pool installation requirements, which you have to consider. Keeping track of these factors is crucial if you want a convenient user experience when you want to use the pool. For instance, it can be highly inconveniencing to install the heater in your pool every time you want to use the above ground pool.

Furthermore, some modern swimming pool heater brands require special tools, which you might not have in your DIY kit. For these heaters, you may have to consult with professional contractor companies.

Sizing your Pool and Heater is Crucial!

Do you have a saltwater pool? Heat pumps work excellent for heating the water during the cold months. Consider the titanium heat exchangers that are durable against exposure to the saltwater. Plus, the gas heaters have various copper components, which can degrade easily over time, and you also have to consider this aspect. Invest in a heater made using cupro-nickel material – which offers high levels of longevity.

Do you want to use a solar pool cover? If you want to heat the pool without using a floating cover, go for one that is a few sizes large for optimal warmth, especially during the night.

What is the average pool warmth level? If you want the water to be over 10° F, go for any of these heaters on this list. Plus, remember to consider factors such as the air and water temperature when heating the water.

When do you want to warm the water? If you only have to heat the water during the warm months, the heaters on this list are excellent. However, the gas pumps are known to have large capacities to make them for heating water supplies.
