Swimming pool heaters are essential if you want to use your pool after the sun has set or if you want to enjoy a longer swimming season. There are many different types and models of pool heaters available to choose from and it’s important to have one that meets all of your needs. While the many available choices and the number of considerations that need to be taken into account may seem overwhelming when purchasing a pool heater, it doesn’t have to be that way. Simply by determining the answers to a few questions before you start shopping, you can greatly narrow down what you’re looking for and make your choice much easier.
Whether you’re in the market for a heater for an above ground swimming pool or an in-ground swimming pool, you will have a number of different types of heaters to choose from. To begin with, different models of pool heaters are powered by different energy sources. For example, swimming pool heaters can be powered by electricity, natural gas, propane or solar energy. The power source that will be right for you will depend upon what is available in your area as well as your preferences with respect to operation, efficiency, cost and environmental impact.
The specifications for swimming pool heaters will typically use BTUs, or British Thermal Units, to express the amount of energy required to raise the temperature of your pool by one degree Fahrenheit. Most models of pool heaters will fall somewhere in the range of 75,000 BTUs to 400,000 BTUs. The higher the BTU rating, the faster the unit will heat the pool water. Therefore, it’s not surprising that higher BTU ratings also come at a higher cost. The speed that you need your heater to warm up your pool at will depend upon your pool usage. For example, if you only want to heat your pool for weekend use, you might want faster results. However, if you are keeping your pool at a constant temperature throughout the swimming season, you might not mind if it takes a few days to raise the temperature of your pool at the beginning of the season.
