Best Tankless Water Heater

Best Tankless Water Heater

One thing that most of us take for granted is the hot water that comes through our pipes. The only time that we are reminded of how important this is is when we run out. Whether it’s running the shower for too long or spending too much time on the dishes, having no hot water is a major inconvenience, especially if it happens for an extended period.For most households, they have a standard tank heater, which means that they are limited to the amount of hot water available at any given time, as it takes a while for the tank to refill and heat up to the right temperature. But what if you could forgo the tank altogether and get piping hot water any time regardless of any water levels? These days, Best Tankless Water Heater are fast becoming more popular as they can provide ideal results without any potential delays. Today, we’ll be looking at why tankless heaters are so much better, as well as show you some of the best models you can find on the market.

How to Choose the Best Tankless Water Heater

Size

If you’re getting a tankless unit to replace one that had a tank, then you are going to be saving a lot of room no matter which model you pick. However, in some cases, it’s better to hook up a heater next to a common hot water source, such as a shower or kitchen sink. In those instances, it’s far better to get a compact unit that won’t take up too much room on the wall. Make sure that you know what space you’re working with before you buy your next unit.

Flow Rate

Because there is no tank to use, these heaters rely on flow rate to make sure that you don’t run out of hot water. While you will technically never run out if you are using more hot water than the system allows it won’t get heated as well as if you stayed within the manufacturer’s recommended limits.

When looking at this factor, keep in mind that they are referring to gallons per minute, and the max flow rate does not usually mean that you can get piping hot water at that particular speed or flow. So, if a heater comes with a three gallon-per-minute flow rate, odds are that it will produce the hottest water at much less than that, such as half a gallon per minute. The total rate only factors in the amount of water that can flow through with minimal heating applied to it.

Gas vs. Electric

As far as tankless heaters go, there are two primary methods by which you can heat your water. First, is to use gas to create a flame to warm the water coming through, and the second is to use electricity. Here are the pros and cons of each system.

Gas Powered

  • Faster to get to temp
  • More reliable
  • Won’t break down as easily
  • Not as exact with temperatures
  • Can increase gas bill
  • Unit will be scalding, which could be a hazard

Electric

  • Precise temperature control
  • Won’t be a safety hazard
  • Better onboard features
  • Won’t heat up as quickly
  • Can break down easier
  • Will increase electric bill

For the most part, people are using electric systems these days because they are much safer, even though they are not as efficient about heating water. Also, having precise control over your water temperature is a huge benefit as you don’t need to worry about accidentally scalding yourself.

Another thing to consider when buying an best electric water heater is how much power is required for installation. Because it will be heating lots of water over time, it can use a lot of energy, which means that your electric bill could be substantially larger if you’re not careful. Make sure that you know what your outlet can handle as well so that you don’t blow a fuse when you activate your best water heater.

Benefits of Going Tankless

It’s easy to see why many people are making the switch to these units. They are far more reliable and will not experience any delays when it comes to heating water. The other primary reason that people like these units is that you can install them directly next to a widely used water source, such as a shower, so as to provide better results each time. Overall, here is what you can expect from going tankless.

  • No running out of hot water
  • Takes up less space
  • More precise control over temperature
  • Can be installed next to hot water sources for easier operation

Overall, the only downside is that some models can break down much easier than others, and they can be expensive to install, especially if you’re getting rid of a current water heater.

Recommended 5 Top Tankless Water Heaters

Rheem RTE 9 Electric Tankless Water Heater

When looking at different models of a water heater, you will see that electric units are by far the most popular because they are more cost effective and overall much safer than gas. With that in mind, our first electric heater is the RTE 9 from Rheem. This company has multiple units in the RTE line, and the 9 is one of the smaller ones you can buy.

If you don’t need a ton of hot water at once, then the RTE 9 can be a great addition to your home. With a max flow rate of three gallons per minute, it gives you enough to handle most of your water needs, but it won’t be able to provide tons of hot water all at once. In fact, if you need water that is heated to more than 120 degrees, the ideal

flow rate for that is less than a gallon per minute. As we discussed above, this is a common issue with most tankless heaters, so don’t think that it’s endemic to Rheem.

One of the best reasons to get an electric unit is the fact that you can control the temperature much better than with gas. To that end, the RTE 9 uses a dial system so you can increase the heat without wasting energy. Best of all, the unit is self-modulating, meaning that you don’t have to control the temperature manually each time you want hot water.

Pros

  • Electric model
  • Flow rate of three gallons per minute
  • ½” water connector
  • Durable brass/copper heat exchanger
  • Modulating power system
  • On-unit temperature control
  • LED indicator lights
  • Measures 10” x 7.25.”
  • One-year limited warranty

Cons

  • Limited heating capacity
  • Can be pricey to install
  • Hot water has to be at lower flows

Rheem RTE 13 Electric Tankless Water Heater

Next, we have the upgraded version of the RTE 9 above. If you need to access more hot water at once, this is the unit to get as it has a better flow rate and a better modulating system. Rheem Electric Heaters are something of the gold standard in the industry, and the RTE 13 is a prime example of that commitment to excellence.

As far as performance goes, you get a flow rate of four gallons per minute instead of three. You also get a slightly better modulator that helps control the temperature and keeps your utility bills from spiking after extended use.

Otherwise, everything you get with the RTE 13 comes standard. It has a half-inch connector for hooking it up to your plumbing system, a rugged and dependable brass

and copper heat exchanger for faster heating, and a temperature control knob. The knob is the best part of this unit as it allows you to set your desired heat or put the heater on standby if necessary.

Pros

  • Electric water heater
  • Flow rate of 4 GPM
  • Standard ½” connector
  • Durable brass/copper heat exchanger
  • Modulating power system
  • On-board temperature control
  • LED indicator lights
  • Measures 10” x 7.25.”
  • Minimum flow rate 0.4 GPM
  • One-year limited warranty

Cons

  • Can be expensive to install
  • Limited heating capacity
  • Not as fast as gas models

EcoSmart ECO 11 Electric Tankless Water Heater

While Rheem is a fantastic brand for tankless heaters, those models are limited with regards to how well they can control your energy output and temperature. If you want something a bit more high-tech that can give you the hot water you need without adding a ton of money to your utility bills at the end of each month.

The Eco 11 from EcoSmart is designed to be as water and power efficient as possible while giving you complete control over your hot water. A digital readout and interface allow you to change the temperature by a single degree if necessary, making this one of the best heaters you can find.

Although the Eco 11 is built with efficiency in mind, it does not provide a ton of water, meaning that you should hook it up for direct use with a particular source, such as a shower or sink, rather than having it service multiple rooms or outlets. With a flow rate of only two gallons per minute, it can’t handle a heavy load. Thankfully, the size of the Eco 11 makes it easy to place almost anywhere.

Best of all, you get a limited lifetime warranty on this device, which goes to show how much EcoSmart stands behind its products

While the Eco 11 was designed for single purpose use, the fact that the Eco 27 has a flow rate of three gallons per minute means that you can use it for multiple sources if need be. However, because of the water efficiency, you might want to keep it to one source to have the best results.

Other features of this heater include a top-of-the-line self-regulating system, a digital

temperature control pad, and a sleek and compact design that can be installed almost anywhere. Also, this particular model is Watersense Certified, meaning that it is highly rated for efficiency. Finally, it comes with EcoSmart’s limited lifetime warranty.
