About the Takagi TK-540X3-NEH

To ensure you get hot water when you want every day, Takagi presents the TK-540X3-NEH tankless water heater that will bring you the most relaxing bathing experience without breaking the bank. You’ll save on monthly bills as it complies with ENERGY STAR requirements and delivers a maximum of 199,000 BTUs at 10 GPM. You get hot water more quickly without spending hundreds of dollars a year. Not only that, the Takagi TK-540X3-NEH tankless water heater has the X3 Scale Prevention Technology that lessens scale-build up. This will extend the life of your water heater three times that of a regular or unprotected water heater and ensure efficiency. With no mineral build-up to clog the pipes, you won't need to do as much maintenance and hot water gets to your showers much faster. 

This water heater uses natural gas for fuel and has the dimensions of 23-⅝” H x 17-¾” W x 11-¼” D. Its height with the cartridge is 35-9/16”. The hot/cold water connection is ¾” NPT. It's approved for working with an external recirculation pump and cross-over valve. The primary heat exchanger for this water heater is constructed of commercial-grade copper for its high resilience against corrosion and 25x improved heat transmission compared to stainless steel. You'll also get the “Peace of Mind” Limited Warranty which has 15 years warranty for the heat exchanger in residential applications, 5 years for all parts in residential applications, and a year of warranty for the heat exchanger and parts in commercial applications, with no exclusions on hard water and scale-related defects. As an outdoor tankless water heater, the TK-540X3-NEH can save you space and keeps any leaks, noisy operation, or harmful gasses outside of your home. This is especially great for small homes in a warmer climate.
