The Navien NPE-24SWE Standard Natural Gas Water Heater is a tankless water heating system that is high-performance and reliable. With over 10 years as the No.1 selling tankless water heater in North America, this system is trusted by homeowners and businesses worldwide.
Dual stainless steel heat exchangers give maximum performance and durability while reducing energy consumption. The unit delivers up to 24 litres per minute at a 25°C temperature rise, suited to demanding applications. It ships configured for Natural Gas as standard; conversion to Propane (LPG) is possible using a separate conversion kit fitted by a qualified engineer.
Up to 16 units can be cascaded with Ready-Link® for increased output, balancing workloads for longer system life. Freeze protection allows operation down to -40°C, and a backlit control panel simplifies setup, operation and troubleshooting with text and icons.
The unit can be installed internally or externally, with the flue also installable externally, for locations with limited internal space or complex flue runs. Built-in full frost protection allows reliable operation in any weather condition.
The Standard range gives the same dual stainless steel heat exchangers, flow rate and cascading capability as the Advanced range, at a lower cost for installations that don't specifically need the ComfortFlow buffer tank and recirculation system — a sensible choice where instant hot water at the tap isn't a priority. A 20% hydrogen blend-ready rating reflects forward compatibility as gas networks gradually change.
