Factors to Consider
If you can’t tell by now, there are a lot of factors to consider when picking out the right gas pool heater for you and your pool, including:
Pool Size – Many gas pool heaters specify the pool size they’re most suitable for and even provide you with a pool sizing chart to help you determine the right sized heater for your pool.
That being said, you can’t go wrong with too many BTUs. The more BTUs a gas pool heater has, the quicker and more efficiently it can heat up water. Using a gas pool heater with not enough BTUs, on the other hand, will consume too much energy and still be unable to provide efficient heating.
Efficiency – When shopping for the best gas pool heater for your family, your pool, and your budget, it’s easy to get hung up on the purchase price of a gas pool heater. However, the operating costs of a pool heater, especially for a gas model, are even more important.
The efficiency of a pool heater plays a key role in its operating costs. Obviously, the more efficient a pool heater is, the better its performance and lower its operating costs will be.
Durability – The durability of a gas pool heater is another obvious and equally important factor to consider. Most quality gas heaters, like the ones reviewed above, feature durable rust-proof exteriors meant to hold up to the harshest weather conditions and heating components designed to last for years.
Heat Exchanger – As their name suggests, heat exchangers transfer heat to pool water. Traditional heat exchangers are made of copper, but many newer gas pool heaters feature Cupro nickel or titanium heat exchangers for their durability and corrosion resistance.
Control Panel – The control panel is the interface and allows you to easily adjust the temperature of your pool water. Most modern gas pool heaters feature digital displays and control panels, and some are capable of automatically maintaining the temperature of your pool water right down to a degree. Many also have alerts, which indicate when a malfunction occurs and identify the problem.
Warranty – As is the case with any large purchase, a warranty is another important factor to consider when choosing a gas pool heater. A warranty can save you hundreds or even thousands of dollars if the heater malfunctions and a repair is needed.
Many quality gas pool heaters come with a warranty. However, some warranties are longer and more comprehensive than others. Therefore, it’s a good idea to select a pool heater with as long of a warranty as possible. It’s a smart idea to fully read the warranty and understand its conditions as well.
Overall Costs – The majority of pool owners only dwell on the purchase price of a gas pool heater, but its efficiency and overall operating costs are even more important. From installation and maintenance to repairs and running costs, the overall cost of a gas pool heater will far exceed its price tag over time and should definitely be considered when searching through gas pool heater reviews and picking the best one for your budget and your pool.
A gas pool heater can be a smart investment in your happiness, but it can also be a sizable one. By understanding your needs and considering these factors, however, you’re guaranteed to choose the right gas pool heater for your backyard oasis.
Making The Decision
A quality gas pool heater can mean the difference between transforming your pool into a warm and inviting oasis or a money pit with little to no reward. Since pool owners have different pools, locations, budgets, and so on, it’s important to choose the right gas pool heater for your exact needs.
Whether you have a healthy budget and an Olympic-size pool or a modest budget and an average-size pool, one of the high-quality gas pool heaters above will fit perfectly for your pool, budget, and lifestyle. So, rather than spend another hour reading reviews while your pool remains colder than Lake Eerie in December, go ahead and pick out a great gas pool heater today.
As thousands of pool owners will attest, a gas pool heater is not only an investment in your happiness but one of the best investments you’ll ever make!
