How to Use Navien Heater in 5 Easy Steps!

The Navien Heater is an ultra-efficient, tankless water heating system. It uses condensing tech to increase efficiency and reduce energy costs. A stainless steel heat exchanger transfers heat from exhaust gases to the cold water, creating hot water for home use.

The user-friendly interface allows you to set the desired temperature with the thermostat. There’s also a built-in flow sensor which adjusts heating capacity when hot water is used.

Optimize your Navien Heater further. Install a recirculation pump to reduce wasted water and get instant hot water at each faucet. Also, add a buffer tank to maintain consistent hot water temperature during high demand. With proper installation and operation, you can benefit from its high-efficiency performance and minimal energy costs. So, consult an expert technician when setting up your Navien Heater.
