The Navien NPE-24AWE Advanced Natural Gas Water Heater is a high-efficiency tankless water heating solution, the best-selling tankless water heater in North America for over 10 years. Homeowners and businesses worldwide trust this advanced system for on-demand hot water.
Dual stainless steel heat exchangers give maximum performance and durability with minimum energy consumption. ComfortFlow® Technology, an integrated buffer tank and recirculation pump, eliminates the cold water sandwich effect, delivering hot water on demand while saving water and energy.
The unit delivers up to 24 litres per minute at a 25°C temperature rise, suited to demanding residential and commercial applications. It ships configured for Natural Gas as standard; conversion to Propane (LPG) is possible using the included separate LPG conversion kit which must be fitted by a qualified engineer.
Up to 16 units can be cascaded using Ready-Link® technology for load balancing and extended system life, and built-in freeze protection allows operation down to -40°C. The backlit EZNav control panel simplifies setup, operation and troubleshooting with text and icons.
The unit offers flexible installation, internally or externally, with the flue system also installable externally — useful where indoor space or flue runs are limited.
ComfortFlow's integrated buffer tank and recirculation pump genuinely solve the cold water sandwich problem that affects many tankless heaters, giving instant hot water without wasting energy running the burner constantly. Cascading up to 16 units gives real scalability for larger commercial installations, and a 20% hydrogen blend-ready rating reflects forward compatibility as gas networks gradually change.
