Navien has been pushing the boundaries of efficiency for 25 years. The NPE-210A is a result of their dedication to providing an effective and green water heating unit. The NPE-210A and all Navien models utilize condensing technology which captures additional heat lost by typical water heaters. The Navien NPE-210A's energy factor is superior to both traditional water heaters and noncondensing tankless models. Reduced vent temperatures due to this condensing technology allow you to use PVC venting, which saves you money and contributes to the ease of installation. The Navien NPE-210A has excellent technology for reducing your heating costs and carbon footprint.
ComfortFlow is Navien's recirculation system and it is included in the NPE-210A. By combining a small insulated buffer tank with a recirculation pump the NPE-210A ensures that you will always have hot water available instantly.
Help the Environment
The Navien NPE-210A will reduce your home's impact on the environment. Eco Pre-mixed Burners reduce CO and NOx emissions by combining gas heating and air before ignition. The result is a nearly 75% reduction in polluting emissions. In fact, an installed Navien NPE-210A reduces CO2 by the same amount as 31 cypress trees.
Navien products reduce energy consumption without sacrificing comfort. Their tankless models, such as this one, only heat water when you need it, reducing energy expenditure. Also, the NPE-210A uses a secondary heat exchanger to transform condensation and exhaust into additional heat. This reduces the ventilation temperature and increases the energy factor. The NPE-210A's efficiency translates directly into savings on operation costs for you!

Using this tankless heat water reduced my electric bill and I still have enough how water for everyone in the house.
Received my order fast. The water heater looks compact and has a sleek design. It’s easy to control and I always have access to hot water. As soon as water cools down to a certain degree, it automatically turns on.
Upgraded my apartment with this tankless water heater last month. Considering only two people use it, we have enough how water and low power consumption.
After trying to fix my old water tank several times, a plumber recommended getting a tankless water heater. I did some research and compared prices. This one was within my budget and works fine for now.

Can I buy it online and install by myself?
HVAC or Boiler installation requires electrical, gas and refrigerant knowledge as well as familiarity with local bylaws and building codes. Failure to properly install HVAC equipment can create safety concerns and performance issues as well as void manufacturer warranties. For those reasons, we always recommends professional installation.
Do I still qualify for the 10 year manufacturer parts warranty if I purchase online?
Yes. The manufacturer will honour the 10 year parts warranty if a furnace or air conditioner or boilers is purchased online and installed by us.
What is the average life expectancy?
The average lifespan of an air conditioner is 15-20 years and an average furnace will last between 10-15 years. Annual maintenance and inspections can extend the longevity and efficiency of your unit. The average lifecycle of a boiler is typically between 13 and 17 years. It is important to note that boilers that are 10 to 15 years old may be 45% less efficient than newer models. A new eco-friendly model will save you a lot of money on your energy bill.
