Designed with efficiency and convenience in mind, the NPE-A2 series is one of the top choices for Colorado homeowners who want endless hot water without the high utility bills.

At ROX Heating & Air, we specialize in tankless water heater installation and recommend the Navien NPE-A2 series for its proven reliability, energy efficiency, and smart design.

Introduction to the Navien NPE-A2 Series

The Navien NPE-A2 Series includes three models:

NPE-180A
NPE-210A
NPE-240A

Each model features varying capacities, so homeowners can select the system that best matches their household’s hot water demand. With its condensing technology and high efficiency rating of up to 0.97 EF (Energy Factor), the NPE-A2 is built to reduce energy use while maximizing performance.

Key Features of the Navien NPE-A2

1. Advanced Condensing Technology

The NPE-A2 extracts additional heat from exhaust gases and recycles it to preheat incoming water. This design dramatically boosts efficiency while lowering emissions.

2. Dual Stainless Steel Heat Exchangers

Unlike copper, stainless steel resists corrosion and lasts longer. Dual exchangers ensure durability and provide a reliable flow of hot water—even during Colorado’s cold winters.

3. Space-Saving, Easy-to-Install Design

The NPE-A2’s compact design allows installation in closets, attics, or utility rooms without taking up the space of a bulky tank water heater.

4. Smart Technology Integration

With built-in Wi-Fi compatibility and Navien’s NaviLink app, you can monitor and adjust your system remotely. This gives you more control and peace of mind.

Benefits of the Navien NPE-A2 Tankless Water Heater

Homeowners who upgrade to the NPE-A2 series experience benefits that go beyond endless hot water:

Energy Efficiency: Reduce monthly utility bills with up to 0.97 EF efficiency.
Endless Hot Water: Enjoy a continuous supply—even during peak use.
Cleaner, Healthier Water: No stored water means less risk of sediment buildup compared to traditional tanks.
Low Maintenance: Self-diagnostic features simplify troubleshooting and keep service visits minimal.
Eco-Friendly Performance: Lower energy use means fewer emissions and a smaller carbon footprint.

Choosing the Right Tankless Water Heater

When selecting a tankless water heater, keep these factors in mind:

Household Size: Larger families with higher demand should consider the NPE-240A.
Energy Efficiency: Look for high EF ratings to maximize savings.
Features: Wi-Fi compatibility, smart controls, and advanced filtration can improve convenience and comfort.
Professional Installation: Tankless systems require expert installation to run efficiently and safely.

  Andrew Y and ROX get my highest rating. Andrew was doing annual HVAC maintenance on our system for the first time. He was punctual and courteous. He did many things that showed a great level of detail on his work. Other companies didn't do this stuff. Too bad I didn't use ROX first. Great job Andrew & ROX. Thanks

  Rox installed my heating and air conditioning system and I was very pleased with the company.  Andrew comes out twice a year for maintenance and inspection of the system.  He is thorough and answers all questions.  I highly recommend this company for installation and maintenance for heating and air conditioning.

  Thanks to Roger, Bert and Ty for installing our new heat pump and furnace. Also to Rose for expediting the service call and Will for coming out that evening to evaluate our system and provide a quick estimate. We were in a rush to get a new HVAC system installed to take advantage of the Xcel rebate that expired the following week. They really came through and got everything done in two days! Everyone was very patient with all our questions and we are very pleased with the excellent work that was done.

  Garrison of Rox Heating and Air performed excellent service. Garrison was punctual, diagnosed our issue and provided several options.  Our AC was up and running within a couple of hours.  We especially appreciated his ability to explain what the root cause of our problem.   Given his great work,  we will continue to use Rox Heating and Air in the future.

  Garrison recently performed the annual fall inspection of my heating system as part their yearly HVAC maintenance program.  As always, he was very thorough and took the time to explain his findings and to answer my questions.  Garrison is very knowledgeable and you can tell he takes pride in the service he provides.  I have no doubts about the upcoming heating season and very much appreciate the care shown by all members of the ROX team ...... thanks!
