Gas vs. Electric Pool Heater
Both gas and electric heat sources are used for heating pools. Even so, some people go for gas, while others choose the electric heating sources. Surely, each option is powered by specific reasons, so each of them comes with both advantages and downsides. If you haven’t yet decided which is the best choice for your pool, we’re here to help you out. Let’s see how both of them work and what’s required to properly install them.
Gas
When using a gas heating source, the water through the heater is pumped, while gas is used to warm the water before it’s charged back into the pool. This type is extremely common in the industry and one of the main reasons is the cost-effectiveness it offers. Even so, it’s also high-performance and efficient, offering proper heating capacity. They are also very easy to install, which is another consideration homeowners look at. However, they represent a good choice especially for smaller pools for shorter periods. Hence, this is why they are more common in warmer climates, where heating the water is not as compulsory as when speaking of colder regions.
Electric
On the other hand, the electric sources are heat pumps that heat the water by running it through a pump that eliminates the outside air and brings the heat into the water by the cooling cycle. Then, the warm water is driven back into the pool to reach the desired temperature. In this case, we’re speaking of less energy used and more effective application compared to the gas heating system. Otherwise, if you have a larger pool, an electric heater will do its job properly, as the heating power is increased. Thus, those who live in colder climates could reliably go for the electric choice.
After analyzing their characteristics, together with similarities and differences, determining which one is the winner is now easier. Hence, it’s all based on your needs but also on the climate type. Even more, it’s also important to consider the placement and size of the pool to make sure you make the correct decision.
Pool Heater Sizing – What Size Do I Need?
The biggest concern when it comes to choosing a pool heater is definitely its size. The size is extremely important as it’s related to heating efficiency. The smaller it is, the lowest performance it will bring. Small units operate slower, thus they will take longer to properly heat the water. On the other hand, a larger machine delivers a higher number of BTU, offering greater heating performance, but also faster heating. This is why, before purchasing a heater, you have to make sure you’ve chosen the proper dimensions that will also suit the pool’s needs. If you still have doubts, take a closer look at the steps you should consider before making the final choice.
- Gas Heaters – Usually used for residential basins and large spas, this type has the highest BTU rating, ranging from 100,000 BTU to 500,000 BTU. Hence, it’s recommended to go for a powerful machine with a great amount of BTU so that it can quickly heat the pool and provide peak performance. If the pool’s surface is approximately 1000-1200 square feet, then you should go for a high-capacity heater.
- Electric Pumps – With an electric pump, the BTU number ranges from 50,000 to 150,000. It produces lower amounts of heat, but they are quieter, and safer to operate. Thus, if you have a smaller pool, it’s recommended to use a lower-BTU powered machine.
- Solar Heaters – When it comes to solar power, things are easier. For instance, for a 600-square feet basin, it’s recommended to have at least 300 square feet of solar panel area. Nevertheless, it depends on the amount of sunlight the panel gets. To bring the best outcomes, a solar system needs up to 10 hours of sun exposure per day.

Even if you own a small above-ground pool or a large in-ground pool, heating is compulsory if you want to enjoy it regardless of the season. All of the products above were specially picked for your needs and requirements, as there’s a various range with both high-end and less pricey models.
Therefore, if you want advanced features, premium heating ability, reliable design with high-quality elements, you should confidently go for the Raypak RAY-014941 unit.
