Outdoor spas and pools are a sizeable investment: extending the warmer seasons with a natural gas pool or spa heater can help you make the most of them. Natural gas pool or spa heaters heat water quickly and economically. And, automatic thermostats and timers enable you to manage usage as you need it, maintaining a constant temperature or only igniting as needed. Have your licensed plumber check your gas supply with Washington Gas before installation so you can achieve the most from your unit.

Heater Size:

Don't choose a smaller heater based on initial costs alone. A larger heater may be more economical as it doesn't have to work as long or hard to heat the same size pool or spa as a small heater does.

Tell your dealer the pool size and the water temperature desired during the coolest month you plan to use it.

For a spa heater, water capacity in gallons and preferred heat-up time are the deciding factors.

Ignition and Burners:

Choose a standard electronic ignition system that activates the pilot light only when necessary or a millivolt ignition for safety and matchless ignition.

Consider a heater with stainless steel burners for greater reliability and longer life.

Maintenance and Conservation:

Pool and spa heaters are built to be low maintenance, but it's always a good idea to protect your heater from the elements as much as possible.

To help keep pool and spa heating costs lower, shop for a natural gas heater that is as close to 100 percent efficient as possible.
