Water heaters have become a basic necessity of living in a modern house. 

Before household water heaters became popular, the only way to get hot water in your house was to boil it on the stove. This was a tedious and time-consuming process. Which often resulted in making your water too hot, or just simply not hot enough.

Today, in-house water heaters provide us with a reliable source of hot water. Whenever we need it. This convenience, as well as the added bonus that we can adjust just how hot our water comes out of the tap. Are some of the reasons that water heaters can be found in almost any household around the world.

However, while they are convenient, that doesn’t mean that hot water heaters are without their drawbacks. In fact, conventional water heaters tend to be quite a bit less efficient. Especially when it comes to their energy consumption.

This is because conventional water heaters store the heated water in a large tank until it is used via one of the home’s faucets. The problem with this is that even when no one is using any hot water. The storage tank needs to run to maintain a certain temperature.

In other words, your water heater is working continuously to keep hot water at the ready. Even when there is no demand for it. This causes a lot of extra wear and tear on your unit. And costs you extra money on your utility costs.

Fortunately, today, you have the option to choose a tankless hot water heater to replace your outdated conventional heater. These units are much smaller, and far more efficient than traditional water heaters. 

Below, we’ll take a look at how tankless hot water heaters work, as well as what to look for in a good top rated unit. 

How Tankless Hot Water Heaters Work

Tankless hot water heaters work by heating your water as it’s being drawn through the unit’s heating coil. This allows the unit to heat your water extremely quickly, as opposed to heating it in advance and then storing it in the tank.

What Makes a Tankless Water Heater Top Rated?

As there are with anything, tankless water heaters have their own set of advantages and disadvantages. 

For starters, they are generally more energy efficient. But since they don’t have a storage tank, they usually can’t supply enough hot water for simultaneous uses such as taking two hot showers in the same house. At the same time.

Below, we’ll go over a few factors that make a tankless water heater better than conventional models. 

Unlimited Hot Water

As long as it is operating within its capacity, a tankless water heater can supply a virtually unlimited amount of hot water. 

The downside to this is that many tankless heaters don’t have a modulating temperature control built into the unit. This means that the heater might not always heat your water to the same temperature when the water flow rate changes.

In other words, you may have an unlimited supply of hot water. But you’re likely to experience occasional temperature fluctuations.

Tankless Water Heater Efficiency

Studies have shown that tankless hot water heaters can be up to 30% more efficient than conventional models. This is due to the fact that the unit doesn’t need to continuous run to maintain your water’s temperature. 

To give you a better idea of how efficient tankless water heaters are. Let’s take a minute to consider how much hot water is typically used throughout the day.

On an average day, most households only use hot water for a small number of tasks. This typically includes a few baths or showers, cleaning and washing dishes, and occasionally doing the laundry

When you add up the amount of time that you actually need hot water throughout the day, you’ll quickly notice that hot water is only needed for maybe a few hours every day. 

But because of the way that conventional water heaters work, they keep a full tank of hot water ready at all times. In other words, your hot water heater works for 24 hours per day, when you only actually need hot water for an hour or two. 

Save on Space

One of the biggest advantages of a tankless water heater is that they are much smaller than conventional units. This is because they don’t have large holding tanks. Which do require quite a bit of floor space in your home.

Tankless models are usually installed directly onto your wall. Which means that not only will you save money on your utility bills, but you’ll also save on floor space.

Gas vs. Electric

Just like conventional water heaters, tankless models come as either gas or electric units. Typically, if you’re replacing your existing hot water heater. You’re going to want to replace it with a tankless model that uses the same power source. However, you always have the option to switch out your power source as well.

Some people might do this if they’re looking to lower their energy consumption and save on money as much as possible. Just keep in mind that if you’re switching out your power supply. Replacing your existing unit will be a much larger job and will likely require a technician to install your new unit properly.

Depending on where you live, gas powered units are typically more affordable to run. However, electrics units tend to be more efficient and are more environmentally friendly.

Lifetime Expectancy

Most tankless water heaters have a maximum life expectancy of 20 years. Whereas conventional models are only expected to last for 10 to 15 years. This is mostly because they do not have storage tanks, which are susceptible to corrosion and leakages throughout the course of its life span.
