Navien - NR-240A-NG - Recirculating Tankless Water Heater - Natural Gas - 8.6 GPM at a 45F Temperature Rise - 0.95 Energy Factor - Direct Vent - For Indoor or Outdoor Installations

Product Overview

Navien has been pushing the boundaries of efficiency for 25 years. The NR-240A-NG is a result of their dedication to providing an effective and green water heating unit. The NR-240A-NG and all Navien models utilize condensing technology which captures additional heat lost by typical water heaters. The Navien NR-240A-NG'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 NR-240A-NG has excellent technology for reducing your heating costs and carbon footprint.

Product Features

ComfortFlow Technology
ComfortFlow is Navien's recirculation system and it is included in the NR-240A-NG. By combining a small insulated buffer tank with a recirculation pump the NR-240A-NG ensures that you will always have hot water available instantly.

Help the Environment
The Navien NR-240A-NG 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 NR-240A-NG reduces CO2 by the same amount as 31 cypress trees.

Incredible Efficiency
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 NR-240A-NG uses a secondary heat exchanger to transform condensation and exhaust into additional heat. This reduces the ventilation temperature and increases the energy factor. The NR-240A-NG's efficiency translates directly into savings on operation costs for you!

Tremendous Durability
The Navien NR-240A-NG uses stainless steel for the Eco Pre-mixed Burner and both heat exchangers. This prevents corrosion and increases the lifespan of your NR-240A-NG. Navien is so confident in the quality of their product that they offer a 15 year warranty on the NR-240A-NG's heat exchanger.

A Product You Can Trust
Navien products are recognized by an array of organizations. The NR-240A-NG is certified by Energy Star; the Air-Conditioning, Heating and Refrigeration Institute; the Canadian Standards Association; and the National Sanitation Foundation.
