Best Tankless Water Heater Reviews 2021

How much should you spend on a tankless water heater? Does spending more translate to better quality? Like with all household appliances, the best tankless water heater is one that allows you to maximize utility at the minimum cost. Considering the long-term savings it generates, a tankless water heater is relatively affordable. However, there are pricier ones whose numerous bells and whistles improve their efficiency dramatically. In our view, these are the best ones to go for. That said, it’s important for us to mention that you should avoid cheap tankless water heaters as they may not give you the best value for your money.

The price of our selected tankless water heaters ranges from around $200 to $1500, with the massive range being accounted for by differences in features. For example, a product that has surge, freeze, and overheat protection is going to cost you more than one that does not, all other factors remaining constant.

A tankless water heater embodies the emerging customer preference of on-the-go or on-demand quick service. All you have to do is turn it on, and Voila! Let’s look at features that you have to consider when looking for a tankless water heater.

• BTUs per Hour - This is the amount of heat needed to raise the water temperature by 1 degree Fahrenheit.
• Power Source - A tankless water heater may derive its power from electricity or gas.
• Flow Rate - This is the volume of water that passes through the appliance in a certain period.
• Energy-saving Capabilities - Does the heater have features that help boost its efficiency factor?
• Overheat, Freeze, and Surge Protection - Your tankless heater’s capacity to withstand unexpected imbalances improves its durability.
• Warranty - Does the manufacturer provide a guarantee?
• Digital Display - The more interactive the appliance is, the easier it is to operate.

When we’re looking at the construction and design of a tankless water heater, there are four main things to consider; power source, BTU’s, flow rate and display. Let’s look at these in some more detail now.

Power Source

The first factor that you should consider when buying a tankless water heater is its power source. If you live in a place where electricity is cheap, an electric heater is what you need. However, if you reside in an area where natural gas is in great abundance, a gas-powered tankless water heater will help you to keep your utility bills at the minimum. We’re confident that this review will help you make the correct decision as our selection includes gas, electric, and gas/electric tankless water heaters.

BTUs per Hour

The amount of heat needed to raise the water temperature is also an important consideration factor. The perfect tankless water heater is one that’s efficient at increasing this temperature; in other words, very little heat leaves the system. The BTUs per hour of our selected heaters ranges from 82,000 to 199,000, which makes them very efficient!

Flow Rate

Further, the appliance’s flow rate is something you have to keep in mind when buying one. You don’t want a tankless water heater that produces drops of hot water, but is supposed to serve a family of five. In our selection, the heater that has the lowest flow rate allows a respectable 6.8 gallons per hour, making it ideal for single users. If you have a big family, we would advise you to go for our featured heaters that have a flow rate of at least 5.5 gallons per minute.

Digital Display

Since the tankless water heater is a relatively recent product, it helps a lot if you can interact with it and set it to your preference. After all, we’re in an age of technologically-adept consumers. One of our selected brands has tapped into this trend by adding an interactive digital display to its tankless water heaters.

Tankless water heaters are naturally more convenient than a water heater with a tank due to their compact size but there are other benefits to these beauties.

Overheat, Freeze, and Surge Protection

Power surges are fairly common, particularly if you live in a place that’s prone to heavy rains, cold winters, and even forest fires. As such, having household appliances that have surge protection is a must. The brands we’ve featured are well-aware of this, and one of them has gone two steps further by adding freeze and overheat protection to its tankless water heater. That way, you will never have to worry about losing your heater prematurely to forces you have little control of.

Energy-saving Capabilities

An energy-saving feature is also a plus on a tankless water heater. An efficiency factor of at least 0.65 enables you to realize significant heating expense savings. With an Energy Star certification, three of our selected products are quite energy-efficient.

Warranty

Finally, the warranty is crucial as it obliges the manufacturer to provide support at zero cost for a specified period. Our selected brands offer a warranty that ranges from one to twelve years. However, there is a caveat: a warranty is only valid if a certified technician installed your tankless water heater. It is, therefore, crucial to have a qualified individual set up your heater once you purchase it.
