Are you maximizing your home's efficiency? Discover what a tankless water heater can do for you!


The Takagi TK-540X3-NIH tankless water heater prevents overheating thanks to its exhaust and water temperature safety control, which monitors the water temperature within the heater. This water heater includes an overheated cut-off fuse that reduces the risk of burns during use. Apart from that, this indoor water heater features a durable primary heat exchanger made of commercial-grade copper, achieving rapid temperature stability in outgoing water, and a secondary heat exchanger constructed of stainless steel, protecting it against corrosion.


This Takagi TK-540X3-NIH outdoor condensing water heater includes an integrated temperature controller and advanced diagnostics, simplifying troubleshooting. Moreover, it provides flexible venting since you can use PVC, CPVC, or ABS pipe for intake and exhaust, making the installation process simple. Plus, this Energy Star-qualified water heater has a 0.95 uniform energy factor (UEF), and a maximum flow rate of up to 10 GPM, ensuring a steady and reliable supply of hot water for various simultaneous uses. In addition to that, we recommend taking care of your water heater by flushing it for a longer lifespan. And, this natural gas heater is backed by a five-year limited warranty, giving you peace of mind.


Takagi has developed sophisticated hot water systems featuring tankless water heaters of unmatched quality. They also provide an economical and durable solution that lasts years after installation.
