Best Electric Tankless Water Heater 

Best Tankless Water Heater – Living comfortably in the contemporary world can often times be very expensive. Machines are being built to make our daily tasks easier, but usually at the cost of our wallet and the planet’s well-being. It’s a good thing, however, that people are becoming aware of the fact that we can have our cake and eat it too, with innovative inventions that are energy efficient, go easy on our money, and allow us to live in modern, 21st century bliss.

Inventions such as electric tankless water heaters (also known as demand-type water heaters) are changing the way we go about our lives. What’s so great about tankless water heaters, you ask? It’s simple.

When you want to shower with hot water, your heating tank heats up and stores the water so that it’s ready to use at your disposal. They can either heat up the water electrically or with gas. This is all well and good, but it causes a lot of inconveniences. First of all, the energy used to store and keep the water heated while you don’t use it is extremely costly. And not only do you have to wait for the water to heat up to use it, it eventually runs out and leaves you with the cold water. This has been a problem for many large families. In the mornings, those that take a bath or shower first end up using up all the hot water and leave none for the rest.

However, it no longer has to be this way with tankless water heaters. Tankless water heaters heat up the water directly so that you can have hot water ready whenever you need it, without the wait, and without the hassles of a storage-based water heater.

We’ve managed to find the top 10 best tankless water heaters and reviewed them down below. If you have any further questions about tankless water heaters, don’t worry. We’ll answer them further down.

Why Buy Tankless Water Heaters? Buying Guide

In Europe and the East, many people have already switched to tankless water heaters and North Americans are starting to catch on as well. The many benefits that going tankless gives you makes taking a simple shower, washing the dishes, or washing the car much easier. However, buying a tankless water heater isn’t something you can just decide to do on the spot. You’ll have to do a lot of research in order to get the right one, or else you might end up wasting thousands of dollars on a water heater that doesn’t even do the job right.Best Tankless Water Heater Reviews

Don’t know where to start? Don’t worry. We’ll do all the hard work for you. Read this buying guide in order to organize yourself and figure out which tankless water heater is best for you.

What to Look for:

Gpm

The most important thing to consider before buying a tankless water heater is the size and gpm. If you get the wrong size, it can cause serious problems with the water pressure and heat flow when using it. To know which water heater is correct for you, calculate how many showers and sinks are in your house and how many of those showers and sinks are in use at the same time. Ask yourself various questions and observe the daily habits of you and your family. Is someone usually washing the dishes while another person showers? Do two people usually shower in separate bathroom at the same time?

Next, you’ll want to determine the gpm (gallons per minute) of your water flow. The more gallons per minute. The bigger the capacity.

For small homes (1-2 showers), tankless water heaters like Titan, Takagi and Eccotemp are perfect. For larger homes (2-3 showers), Stiebel Eltron, Noritz, and Rinnai are great.

Cost

When buying a tankless water heater, it’s very tempting to just go for the cheapest one. In the end, they all do the same thing, don’t they? The thing is, not only do you have to take into account the cost of the actual device, but also, installation costs. Would you rather buy a cheap water heater but pay a lot for installation from specialists, or an expensive one with cheap installation from your average plumber? Will you need to replace your pipes? PVC or CPVC?

Climate

Buying tankless water heaters in colder climates can be a bit difficult, mostly because when the temperature is very cold, the water heater can get overworked and stop functioning. Many tankless water heater manufacturers have a detailed map that shows you how well their product performs in your state.

Type

Electric Vs. Gas

Tankless water heaters can either be gas-fueled or electric. Powering your tankless water heater with natural gas is much more affordable in the long run but buying and installing electric ones are much cheaper. Not to mention that electric tankless water heaters are more durable and perform better than their gas counterparts.

Installation

Something else to consider is if you will want to install the water heater yourself. How easy is it to install the water heater yourself? Will the warranty be void if you install it yourself? There are some tankless heaters that will only void the warranty if you pay for it to be installed but later on install it in some other place yourself.

Your water

Do you receive hard water or soft water? Hard water contains minerals that can have a chemical reaction with the metallic tubes in your tankless water heater unit. This can lead to a very short lifespan for your water heater and can cause bacteria to accumulate in the unit. Check which type of water you receive and buy accordingly. Companies like SioGreen have water heaters with Quartz tubes to specifically counter this problem.

How does a tankless water heater work?

A tankless water heater works by installing the heating unit and power source near the place you want the hot water to come out from. When you open the tap, the water passes through the heating unit, where it is instantly heated up either with gas or with electricity.

How do you install a tankless water heater?

The best thing to do would be to hire a professional, for safety reasons and to keep the warranty. If you want to do it yourself, however, contact the manufacturer so they can guide you through the process and give you information. You might want to check with your town or city to see if you need some kind of permit in order to install it, especially if the water heater is from a foreign company.

What is the difference between hard and soft water?

Hard water is water that contains more minerals, like calcium, chalk, and lime. Soft water mostly only contains sodium.

Tankless Water Heaters lasting Compared to Traditional Water Heaters:

Water heaters with tanks can last about 12-15 years until their performance begins to deteriorate. Tankless water heaters can last more than 20 years.

How much does a tankless water heater cost?

A small tankless water heater can cost anywhere between $115 to $300. A bigger unit usually costs around $300 to $1,500.

Installation Cost:

Installation cost can reach up to $700, depending on the company and type of tankless water heater. Electric water heaters usually cost less than those powered by gas.Best Tankless Water Heaters
