Our thoughts on the Navien Premium Condensing NPE Gas Water Heater

The Navien Premium Condensing NPE Gas Water Heater is easy to install and repair thanks to the accessible waterway components including the pump, water adjustment valve, and 2 way-valve. It can even be installed outdoors. It is low polluting due to its high energy efficiency rating and is easy to control and troubleshoot via the intuitive control panel display.

This range comes in two sizes which will suit any household, or business. This style of boiler can generally provide adequate hot water for most average-sized family homes. 

Technology you can trust

The Navien Premium Condensing NPE Gas Water Heater is controlled with the programmable LCD control panel which also allows troubleshooting. This water boiler includes features that guarantee reliability and robust running operations. 

The primary and secondary stainless-steel heat exchanges provide optimum effectiveness and sturdiness. Stainless steel, rather than copper, reduces the risk of corrosion Equally, Navien’s patented ComfortFlow ™ technology is a fantastic addition, which includes a built-in buffer tank and recirculation pump to provide maximum comfort but with a quiet running volume.

Maximum performance

The Navien Premium Condensing NPE Gas Water Heater “learns” your hot water usage patterns and adjusts the operating frequency to respond to a busy, high use period. Via the intelligent front panel display, you can monitor the temperature as well as conduct self-diagnostic processes.

Frost protection

A built-in sensor inside the boiler automatically detects the ambient temperature and can maintain normal operation during freezing temperature down to -40 °C. These abilities in low temperatures significantly reduce the risk of your water heater breaking down during the cold winter months.

Engineering excellence from South Korea
