Four NPE-S2 Standard Premium models offer a Uniform EnergyFactor up to .96, providing more output, lower installation costsand lower operating costs.

It is worth switching to a tankless water heater if you are looking for a more efficient option. Tankless water heaters can save you money on your energy bill, and they can also have a longer lifespan than traditional water heaters.

Three NPE-A2 Advanced Premium models offer a Uniform Energy Factor up to .95 and feature Navien’s patented ComfortFlow system.

Descaling is a process that removes mineral deposits from the inside of the tankless water heater. It’s something that needs to be done every few years, depending on the hardness of your water.

Navien condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing boilers. The result is a reduction in energy consumption, lower CO2 emissions and low exhaust temperatures allowing the use of less expensive venting materials such as Schedule 40 PVC.

Installing a Navien tankless water heater is best done by a licensed plumbing contractor professional because it involves disconnecting and reconnecting gas lines. Venting and wiring also require professional expertise to ensure the installation meets building codes. Use Navien’s installer and service locator to find a specialist in your area.

To choose the right size tankless water heater for your home, you will need to consider a few factors, such as: the number of people in your household, the average water usage in your household, and the climate in your area.

Navien Premium Efficiency condensing tankless water heaters are the #1 selling high efficiency condensing tankless water heaters in North America. The NPE-2 series offers ultra-high efficiency up to 0.96 UEF to keep your utility bills low, endless hot water, and exclusive ComfortFlow® technology with a built-in recirculation pump and buffer tank.

Ultra high-efficiency tankless water heaters—also known as condensing tankless—use two heat exchangers to supply endless hot water when you turn on a faucet. They use less energy (and money) than traditional water heaters because they don't need to reheat the water over and over.

Navien tankless water heaters have a lifespan of up to 20 years. However, proper maintenance is required in order to achieve this lifespan.

The Navien NPE-2 series is a line of high-efficiency condensing tankless water heaters featuring a user-friendly control panel. These tankless water heaters can be installed indoors or outdoors, for residential or commercial use.

Condensing tankless water heaters need a condensate drain. This is because when the water is heated, it produces condensation that needs to be drained away. The condensate drain ensures that this doesn’t build up and cause problems with the tankless water heater.
