Gas-powered tankless water heater systems are among the most efficient water heating solutions. According to research, using propane tankless water heaters reduces energy consumption and greenhouse gas emissions by about 50%. These are among the reasons many homeowners opt for tankless water heating systems. Data shows that the tankless water heater market in the U.S. is expected to grow by 8.7% annually over the next decade.

For plumbing and heating professionals, using the best venting practices for tankless water heater systems, such as using concentric vents, providing vents that meet local code and going for aesthetically pleasing vent designs is crucial to ensuring homeowners love their installation and are within budget during the project.
