Check Price on Amazon

To understand what makes it so special, however, you’ll first need to understand what and how natural gas models often work.

The average natural gas tankless water heater is powered through a live flame that warms up internal coils called heat exchangers.

Cold water is cycled around the coils, and because they’ve been warmed by the flame, they warm the water as well.

The badside of this heating system is that it releases fumes because of the live flame.

Most natural gas units simply send out the fumes through an outdoor venting system, but the NRC98-DV-NG has taken a new approach:

It first condenses the fumes, then expels them, reducing their harmful properties to such an extent that the NRC98-DV-NG can actually be installed indoors.

Now that’s a tankless water heater worth buying!

Check Price on Amazon

It’s enough to service anywhere from 4-6 bathrooms at a time and still has power left over.

It’s so strong it’s almost commercial grade.

Even more incredibly, the NR111-SV-NG is simple to install and lightweight. You’d think it would weigh a ton when it’s capable of doing so much, but it’s still only 44 lbs.

It’s an indoor model to boot, so you can put it anywhere there’s proper ventilation to outside air.

The con of its incredible power is that it’s also incredibly expensive, so be sure to factor that into your final decision.
