Best Navien Tankless Water Heater Reviews
One reason we selected the NPE-240-A as the best tankless water heater from this manufacturer is because it is so much easier to use than the others you might consider for your home.
With older or more traditional models, there is always a risk that you might turn the temperature up too high, which can lead to boiling hot water coming out of the taps that can burn your kids and other family members. The NPE-240-A, which rated among the top Navien tankless water heater reviews has simple arrow buttons that let you adjust the temperature and a screen that shows you the exact temperature selected to reduce the risk of burns and other accidents.
Navien is one of the only companies to create an intelligent preheating technology feature that comes standard on many of its models like this one. This feature works in the same way your oven does to slowly increase the temperature inside before you use. As the H2O supply circulates around inside the heater, it comes up to the temperature that you want in just a few seconds to reduce the wait time that you might otherwise experience.
Designed to work with standard 1/2-inch gas lines, it will also work with pipes of different lengths and can work with PVC vents of up to two-inches in size to safely vent any excess gas out of your home.

NPE-240A Premium Condensing
Many of the models available share similar names and ID numbers like this NPE-240A, which has the same model number as our number one choice but has a condensing design that makes it a little different.

The stainless-steel heat exchangers inside last longer than the exchangers made from cheaper types of metal and do a great job of ensuring the H2O comes out of the heater at the perfect temperature.
Once you turn it on, the supply will come out of your pipes, pass over those exchangers and slowly come up to temperature before the heater pushes it through the lines to your bathroom or kitchen. It works with the 1/2-inch gas line(s) that you probably already have in your home and allows you to convert the system to work with your home once it arrives in the mail.
One of the top reasons to invest in this model from Navien is because it features intelligent preheating technology that actually begins heating the H2O before you need it. With other models, you can only use as much water as the heater can provide, which refers to its flow per minute rating, but this model increases the temperature of the supply earlier to reduce the time that you spend waiting for hot-water. It also has built-in connections that work with most gas systems as well a push button controls on the bottom and a digital screen.
