Small pool heaters are not perfect for every pool. They are, of course, best for small swimming pools. The question is: what size pool heater is the right size for your pool? Here are some tips to help you decide on the proper size:
• Larger – it is better to get a heater that is a little too big rather than a little too small. In fact, it is recommended to purchase a heater that is one size larger than the basic requirement.
• Pool size – to find out the area of the surface of a pool, multiply the length by the width.
•Desired pool temperature – the temperature of a pool is a personal preference. But generally a pool is kept between 78 and 86 degrees Fahrenheit. All you have to do is decide what temperature you want your pool to be kept at.
• Outside temperature – figure out the average temperature of the coldest month of pool use (and keep in mind that heat will be better retained if a solar blanket or pool cover is used). To find out how much temperature rise you need, subtract this temperature from the desired pool temperature.
•Heater size – the size/strength of the heater is measured in BTUs. To find out the approximate BTU necessary for your pool (and to find out whether or not you can get by with small pool heaters), multiply the pool surface area (in square feet) by the temperature rise by 12. (Pool Area x Temperature Rise x 12)
This equation works, assuming about a 1 degree Fahrenheit rise in temperature per hour.

To find out for certain whether or not small pool heaters are best for you and your pool, contact a pool specialist. And be sure to keep in mind that solar heaters are a cost-effective option – while they may cost more money upfront, they will save you a ton of money in the long run. Whereas most pool heaters are energy-guzzlers (and can therefore run up the utility bill), solar pool heaters cost nothing to run.
