Navien CR-210 a

Navien Condensing 98% Tankless Water Heaters provide an unlimited amount of hot water at a steady temperature, whenever you need it, for as long as you need it.

Because this product boasts the industry's highest efficiency rating (98%) means customers can cash in on low annual operating costs as well as receive the best payback, compared with conventional tankless or tank-type water heaters. Navien Condensing 98% Tankless also enjoys the highest gallons-per-minute (GPM) when comparing input BTUs.

Navien utilizes condensing technology, which uses less gas, resulting in less CO2 emissions than conventional water heaters.

Navien's ECO Premixed Burner not only dramatically reduces NOx emissions but also boasts the industry's lowest level of emissions.

Partly dissolved NOx in condensed water neutralizes the alkaline household sewage, improving water pollution.

A Navien occupies approximately 90% less space than a tank-type water heater. In addition, a Navien mounts on your wall, freeing up 100% of traditionally lost floor space. Built-in leak detector prevents damage to water heater as well as personal property.
