Best Electric Tankless Water Heater

The traditional and bulky tank water is slowly fading away from our homes. Not only that it takes a lot of space, but it’s also a high consumer of both electricity and money. Nowadays, people are interested in buying and using equipment that saves time, money, and space. It’s the case of the electric tankless water heaters which become more popular as we speak.

What’s the technology behind tankless water heaters?

The principles of tankless water heating are straightforward. They don’t heat and store the water in a tank (tankless!) where the energy dissipates throughout the day, but they heat the water whenever you want. You use the amount of hot water you need, for a specific amount of time.

The concept of waterless heating isn’t all new in Europe and Asia, where it has been used for many years. It was only the 90’s when the waterless system started to be more popular, with people being more interested in “green” technologies.

When it comes to the mechanism, the tankless water heaters are rather simple (no matter if they’re gas or electric). A flow sensor identifies when you’re turning the hot water faucet on, activating the tankless water heater. Several heating elements will keep on heating the water until the flow sensor identifies that the water doesn’t flow anymore (since you’ve turned the faucet off).

Why choose an electric tankless water heater?

The numbers don’t lie, and the industry of electric tankless water heater has a 7% annual growth. It’s because the electrical system saves your resources while impressing with efficiency.

Here are some of the benefits of tankless electric water heaters:

  • They boost the current systems
  • They’re great for point of use
  • They’re a good investment for the long run
  • The maintenance is simple
  • They’re a solid choice for the low use households

What to look for when selecting the electric tankless water heater?

Even if some may consider the electric tankless water heaters pricey, they’re a wise investment to make. They’re highly efficient and long-lasting, surpassing both the gas and the tank models in terms of durability.

The market gives you numerous models to choose from, so a buying guide may become handy.

Without any further ado, here are some aspects to consider when shopping:

  • The material is made of

With most regular tankless water heaters being made of limescale material, it’s natural that you want something that is to care for. Take a look at the content of the water heater so that you get low maintenance and long lifespan.

  • Incoming water temperature

If the water temperature isn’t higher than 30F degrees, the electric water heater is the perfect choice for you. When you want the heat to go as high as 50F, no electric heater is going to be a reliable option.

  • Flow rate needs

Flow rate is a fundamental aspect to consider before buying. You need a high flow rate for a washing machine, bathroom shower, and dishwasher, whereas the kitchen faucet only requires a low flow. The flow rate of the heater goes higher with the price. The better the flow rate, the higher the price.

  • Size

There are models with various sizes on the market, so finding one according to your needs isn’t complicated. You also need to think about where you’re going to install the heater too. Under the sink is a great place to install an electric tankless water heater, but that’s just one example to name. Selecting the site is also going to help you narrow down your choices when shopping.

One last thought before you go shopping

You must know the bit and bobs before you go shopping so that you don’t end up with a model that is too big or too small for your households. Don’t forget to keep an eye on your wallet also!
