Navien Tankless Water Heater

The NPE-A

The best tankless water heater Navien offers. The Navien advanced water heater results in more output for the investment, lower installation costs, and lower operating costs. Customers can feel confident in their choice to go with the NPE-A for their home.

This water heater is the first and only system that incorporates a built-in insulated buffer tank and recirculation pump. The buffer tank eliminates the “cold water sandwich” effect and minimum flow rates of other water heaters. The recirculation pump is designed for efficiency. By reducing the time it take to get hot water, homeowners are seeing drastic decreases in their water bills.

Up to 60 feet of venting with 2 inch PVC

  • With the advanced series, there is no need to cut new chases. Low exhaust gas temperatures allow the use of PVC, CPVC, system 636, and polypropylene venting systems. These are designed to save time and money

Flexible Options for Field Gas
The negative pressure gas valve and dual venturi system allow for easy field convertibility from a natural or liquified petroleum gas operation.
