How to choose a pool heater

Do you want to warm your pool and extend the swimming season? If so, you can choose from a wide range of heating solutions. Here are a few things to consider when selecting a heater for your pool.

Your needs and budget
The size and location of your pool, as well as the local weather conditions, will determine how much heat is required (calculated in BTUs) to bring the water to a comfortable temperature. Look for an AHRI-certified water heater to ensure the device delivers the necessary BTUs. If you’re watching your budget, make sure to consider both the purchase price and the unit’s energy consumption.

The different options
Once you have a good idea of your requirements and how much you’re willing to spend, you can select the best heating solution from the following:

• Heat pump. This popular device is the champion of energy efficiency. It extracts and amplifies heat from the ambient air to warm your pool water. However, the nature of this system makes it less efficient in colder seasons. Consequently, if you want to swim in your pool in the fall, a heat pump may not live up to your expectations.

• Gas water heater. This device heats pool water at record speed and allows you to extend your swimming season considerably. However, gas water heaters use a lot of energy. As a compromise, some people take a hybrid approach and use a heat pump in the summer and a gas water heater in the spring and fall.

• Electric water heater. If you have a small pool or only swim occasionally, this system will more than meet your needs. Although electric water heaters are affordable and compact, they can drive up your electricity bill when used frequently.

• Solar energy system. Do you only need to warm your pool a few degrees? If so, you can harness the sun’s energy with photovoltaic panels or through a network of pipes that capture and transmit heat to your pool. However, keep in mind that these systems are weather-dependent and don’t generate much heat.
