Propane and Propane Tankless Water Heaters

There has never been a better time for propane to fuel American homes. Homeowners are looking for smart approaches to enhancing home enjoyment and value while minimizing environmental impact. Whether providing an instant flame for gourmet cooking or offering an endless supply of hot water in the shower or backyard pool, propane is helping millions of American families enjoy richer, more comfortable lives with less impact on the planet. And the lower cost of operation means homeowners will be rewarded for a smart choice each month with lower energy bills. Getting more for less while helping the environment - that’s a message worth sharing.

Fact: Propane delivers instant hot water with a lighter impact on the environment.

• Propane tankless water heaters produce 61 percent fewer greenhouse gas emissions than electric tankless models.¹
• Propane tankless water heaters save families an average of 10 to 20 percent of their daily water use.²
• Propane tankless water heaters reduce standby energy loss by up to 20 percent compared with tank water heaters.²
• Propane tankless water heaters cost approximately 60 percent less to operate than tank water heaters.²
• Propane tankless water heaters are Energy Star qualified for efficiency; electric tankless water heaters are not.

Note: Using any kind of Tankless Water Heater is better for the environment than using a tank water heater. And even though electric tank water heaters are not energy star rated, that are significantly more environmentally friendly and less costly to operate than even Energy Star rated electric TANK water heaters.
