Types of Navien Tankless Water Heaters

Here are a few different types of Navien tankless water heater to shop for.

Condensing Tankless Water Heaters

Condensing tankless water heaters ReviewsThis is what Navien is known for. Their condensing water heating system is renowned. These types of appliances use a heat exchange fueled by a gas valve to deliver endless hot water. They take up much less space and are more energy efficient than a tank heater. They also have a control panel that lets you control exactly the amount of heat.

Gas Valve Heaters

This is the type of heater you can expect to purchase from Navien. These use natural gas with a heat exchanger to heat up your home’s water. It also fields convertible. Navien uses smart preheating technology to get water heated as quickly as possible.

Recirculation Pump

These are imperative to purchase if you want hot water fast. This recirculates the water through a buffer tank, making it easier to get a hot supply of water on-demand. If you have a larger home, you will want the recirculation pump because it means that it will take less than 60 seconds to get hot water directly to your faucet.

Features of Navien Tankless Water Heater

Navien water heaters are among the best because of their on-demand hot water design. With heat exchange systems, users instantly get endless hot water without increasing energy consumption. There are some special features that are specific to Navien as well, such as ComfortFlow® technology.

Energy Efficient

Energy Star certifications come easily for Navient. These heaters were made to conserve energy and heat up fast without using electricity. While the heaters do use gas in most cases, you can use recirculation strategy to keep water flowing that’s hot and ready without using any additional resources. This helps you save on utility bills as well as reduce your carbon footprint overall.

Space Saving

Space saving tankless water heaterTankless heaters are meant to be compact. They typically fit into any closet space, but you can also mount outside if you have an outdoor model. Navien has multiple mounting instructions for different models, so you can find one that meets the size that you need in your home.

Strong 15-Year Warranty

Most water heater companies do not have warranties longer than 12 to 24 months. However, Navien takes it a step beyond that to offer the longest warranty on heat exchange elements in particular. While Navien offers several different warranties, only the heat exchange elements are covered in the warranty, so it’s important to check what you are getting with the warranty when you purchase the appliance.

Condensing Technology

With condensing water heaters, you get the instant heat that you crave as well as continuous heat that you don’t have to wait for. A large part of this is ComfortFlow® technology, which includes the internal recirculation pump and a buffer tank.

Not all Navien models come with this technology, and you should expect to pay a little bit extra. If you are looking into Navien for commercial heaters, then you can earn up to 3 LEED points with a recirculation heater, according to Navien Inc’s website.

Stainless Steel Heat Exchangers

These offer strong, durable, and long-lasting heat for your water pump. You can continuously heat up water over the exchangers for endlessly hot showers. With stainless steel, you don’t have to worry about rust or other problems from lower quality materials.
