In this article, we are going to talk about the Navien tankless water heater reviews and why they are so popular among the masses.
When tankless water heaters first came out, they were notoriously unreliable, noisy, and were synonymous with a phenomenon known as cold water sandwich. But things have changed and today, they are more popular and recommendable than traditional units that have tanks. Nowadays, it’s not just about getting a tankless water heater that works; it’s finding one that works efficiently both in terms of speed and energy consumption. In that regard, one manufacturer has distinguished themselves for their continuous efforts to design efficient, eco-friendly, and affordable options.
Why Navien, what do they stand for?
Just like in the motor car world where we have Cadillac, Mercedes Benz, and then other cheaper, more common brands, the same ranking would apply in the world of water heaters. Navien is an above average brand that commands huge respect. Since 1978, it has been able to come up with innovative ways to ensure that their tankless water heaters are not just energy efficient, but also very eco-friendly in terms of Co2 emissions. However, some may find their units a bit costly when compared to other brands in the market. Which is why, like we started by saying, a Cadillac and Toyota are both motor vehicles, but their prices are a world apart.
Best Navien Tankless Water Heaters
Frankly, this is one of the best tankless water heating units you’ll find. We have no desire to praise the manufacturer but if we have to call a spade a spade, the NPE240 has everything one would wish for in a water heater; reliable, safe, energy efficient and low energy bills. Each time you think of Navien NPE240 S, think of a heater that can comfortably serve a huge mansion with 6 bathrooms or more.

Caring for your Navien Tankless Water Heater
Navien has something for everyone and there’s always a variety of products for you to pick from. Usually, their tankless water heaters are classified into 2; residential use and commercial use. It will all depend on your personal needs and preferences; like we mentioned earlier, some units can be used for both purposes. Clearly, Navien has invested much technology and innovations in order to make their products more efficient and eco friendly. However, just as with every machine, maintenance is very important if your tankless water heater is to serve you long and efficiently.
This is your unit’s worst enemy as hard water contains calcium and magnesium. When the water is heated, the calcium ions are separated and start a scale buildup. This scale buildup damages the heat exchanger with time and before you know it, the unit isn’t working or takes ages to heat water. Investing in water softener will go a long way in protecting your unit from damage as well as guarantying you of total efficiency. Flushing your tankless water heater after every 6 months is recommendable.
Always ensure that your unit’s temperature settings are safe. The standard safe level for a water heater is 122 degrees. Hot water at 150 degrees will easily cause 3rd degree burns to children within seconds of exposure. In a home that has young children, the recommended setting is 120 degrees; most Navien water heater units have automatic thermostats that are controlled by a computer to ensure consistency safety.
Seeing that all Navien tankless water heaters use either propane or natural gas, the question of venting the fumes emitted is very pertinent. Ensure that the unit you’re buying is able to effectively vent out fumes and exhaust gases; a fan is used to expel these fumes from the unit out into the atmosphere.
Always read the user manual keenly before installing your Navien tankless water heater. Many home owners have rushed to do the installation themselves, or hired ordinary plumbers to come to help out; only for them to learn later that the Warranty becomes void the moment installation is done by an unlicensed professional. Having a professional install the unit isn’t just about protecting the warranty; it’s also about your safety and that of your property.
Applications for use:
Another common mistake that some homeowners make is using the wrong appliances and applications with their units; for instance, a unit designed for residential use cannot be converted for commercial use. Similarly, you want to be very sure before converting your residential unit for use in a sauna. Take time to learn the applications that the unit can support. In most cases, these applications include baths, sauna, dishwashers, laundry machines, indoor wall heating, and sinks, and so on so forth.
Indoor or outdoor use:
Before you get carried away by the features and specifications, take a moment to consider what you need your Navien tankless water heater for. This can either be indoors or outdoors. While some people love the space-saving abilities of tankless water heaters, others want them outdoors in order to minimize any noise and accidental fume emissions. Decide on which one you’re looking for from the word go.
Ordinarily, you can pick a large unit that supplies the entire building with all its water heating requirements or a POU unit. A POU (point of use) unit is used to supply hot water for a specific task like showering, dishwashing, laundry machines, and so on.
With Navien Tankless water heaters, you’re always assured of great efficiency and performance, not to forget the cutting edge technology and innovation inherent in Navien products. However, be ready to cough out some more cash in installation costs. Most units you’ll buy will be very clear that installation has to be done by a licensed professional. With proper installation and regular maintenance, these units can serve you for many years without letting you down. Do your comparison and contrasting carefully before purchasing your preferred unit; remember that cheap can be expensive. It’s always better to invest in a good quality Navien unit once and for all and close that chapter.
