EZ Series PRO Notable Features
Greater fuel efficiency: The new EZ Series PRO line offers an improved 0.98 UEF rating, up from 0.96. This additional efficiency is intended to help home and business owners reduce their fuel bills while also generating fewer harmful emissions.
Single gas type with easy conversion: Natural gas is the default fuel on all new EZ models. But each model comes with a simple-to-use kit containing all the parts needed for conversion to liquid propane (LP).
Bluetooth® connectivity for greater control, quicker startups: All EZ Series PRO models enable Bluetooth® connectivity, providing users greater control over functionality. This includes setting water temperatures and deploying pump timers to quickly deliver warm water to the shower with minimal waste. To create a pump-assisted, hot-water recirculation system, installers can combine any EZ Series model with the Noritz RPK-EXT External Pump Kit, sold as a separate add-on component.
