How To Choose The Right Swimming Pool Heater

Finding the right swimming pool heater can be tricky. There are so many options available on the market for you to choose from, but we will simplify the process by giving you a few tips and tricks that you should know before searching for your perfect heater.

Your heater size should depend on the time needed to heat your pool or spa to your desired temperature. If you wish for rapid heating and tend to heat your pool prior to each use, you should scope out larger heaters. A smaller unit would suit you if you prefer to gradually heat your pool to the perfect temperature and then maintain it as such. Make sure to check out the specs of your pool or spa to pick the right heater:

1. Indoor or outdoor pool?

2. Powered by propane, natural gas, or electricity?  All have their pros and cons.

3. If outdoor: the amount of sun exposure your pool receives, and average wind speeds

4. Your ideal temperature maintained and temperature rise per hour

5. The surface area of your pool

6. How much volume can your pool contain? (Length x Width x Average Depth x 7.48)

7. Use of solar blanket

8. Length of pool pump usage per day

9. Where will you place your heater? Is your equipment pad large enough?

This information will help you decide what size suits you best. Typically, anything under 500,000 BTU is considered a residential heater.
Gas heaters are more suited for rapid heating in a short time span, but may be more costly to operate.
Electric heaters are less expensive, but require a longer time span to heat up.
Where you decide to place your heater will be critical, as you must ensure that it is not placed within 5 feet of the inner surface of your pool.

Make sure there's enough space for easy maintenance and good airflow. Keep ventilation clear from doors and windows if outside, and have a pro check for proper indoor ventilation. Follow local codes during installation. If indoors, elevate your heater a bit to prevent propane from pooling. Solar heating can help cut costs and work alongside your heater to warm the pool naturally. Use solar blankets or domes to reduce the size of the heater needed. As a pool or spa heater is an important and costly investment, it is recommended that you seek the advice of a licensed contractor who understands all these requirements, can give a professional opinion, and can ensure a job well done.
