Frequently Asked Questions
What size pool does a 175,000 BTU heater suit?
It suits smaller in-ground pools and spas. Sizing depends on surface area, temperature rise, and climate, so have a pool professional size it for your install.

Liquid propane. Fuel is set by model. Order 460792 for the 175K BTU natural gas version.
Should I choose 175K or 200K BTU?
The gap is small. 175K is the economical pick for a smaller pool. Step to the 460731 at 200K if you also heat a spa or want faster recovery.
