Navien Tankless Water Heater Reviews
Tankless water heaters are an excellent option for homes today because these models let you wash dishes, take showers and use hot water for other needs without standing around and waiting.
Instead of using a tank, many have coils or a similar design that allows the supply to quickly move across a heat source and come up to temperature fast, and you can usually select the temperature that you want to use. This prevents any scalding or boiling coming out of the tap.
One of the top names in this industry is Navien, which makes both propane tankless heater and designs that work with natural gas lines. You need to make sure that the tankless heater you pick will work with the lines that are already in your home.
Our favorite is the NPE-240-A, which comes with a warranty that covers some parts for five years and others for up to 15 years.
Best Navien Options On The Market Today
OUR TOP CHOICE
It has a built-in pump that keeps the supply circulating inside the heater and continuously moving across the coils to provide you with instant hot H2o almost as soon as you turn on the tap.
This tankless heater works with two-inch PVC piping and has digital controls on the front for more natural changing of controls and settings.
A Quick Overview Of Terms
I use a few uncommon abbreviations and terms in this article, which I’ll quickly explain here:
British Thermal Unit (per hour), the amount of heat required to heat one pound of water one degree. The higher this number, the hotter your tankless water heater.
Gallons per minute. In this context, how many gallons per minute a tankless water heater can effectively heat without starting to output cold bursts. Bigger is better, once again.
A condensing heater keeps the propane or natural gas more highly compressed, resulting in more efficient heat output that isn’t as affected by the weather. Non-condensing units (the majority) lack this feature and may perform up to 50% less efficiently in cold weather.
Top Choices For Your Money
- Works as-is or with the addition of a separate cover
- Comes with both a pump and a buffer tank
Digitalscreen is easy to see
- Is too large for installation in some homes
- Will cost more to run than smaller models do
Our top choice is easily the NPE-240-A, which gets the highest reviews from customers because it comes with so many great features.
Among those features is a pump that recirculates the supply inside to keep it at a higher temperature and a buffer tank. These elements work together to provide your home and family with an on-demand supply of hot water.
Designed to work with PVC venting of up to 60-feet long, this model is easy to install but does require professional installation to maintain your warranty, which covers most parts for between five and 15 years.
This tankless heater also works with natural gas lines of 0.5 inches that you already have in your home.
A digital screen near the bottom helps you see the temperature you selected as well as all other settings. Conveniently placed buttons nearby help you move between settings, change the temperature and even set a timer to tell it when you will need hot water.
- Uses intelligent technology to preheat the H2o before you need it
- The convertible design works in most homes with natural gas
- Includes an installation kit
- Installation kit may not feature all the parts that you need
- May shut itself off because it thinks you don’t need water
For homes with existing natural gas lines, this is one of the top options because it works with gas lines of standard sizes.
One of its top features is that it uses intelligent technology to quickly preheat water before you need it, which helps the H2o reach the maximum temperature that you set even faster. A built-in buffer tank and recirculating technology allows it to keep moving and helps regulate its temperature.
As a convertible design, the 240S-NG will work in most homes that use natural gas and will let you convert the tankless heater based on your needs. It also comes with an installation kit that makes installation more manageable, but this package may not come with all the parts that you need.
This tankless heater has two heat exchangers inside that regulate the supply and use stainless steel that lasts for years, and you’ll get the same digital display and buttons as found on our top choice.
