Why Choose an Electric Tankless Water Heater

Installing an electric tankless water heater over the other models comes with various advantages. First, it reduces the amount of energy consumed. It will, therefore, reduce your energy bills. These heaters only draw power when you need to use hot water and for a short period. They are not continuously running as compared to other models. They will, therefore, heat a small volume of water.

Traditional water heaters, on the other hand, draw a considerably high amount of energy, since they run longer. Also, they must heat the entire capacity of the tank, only to deliver a small quantity of water that is needed when you run the tap. Furthermore, the tanks on the traditional water heaters allow heat to escape, regardless of the level of insulation. Therefore, the water inside the tank cools constantly, thus forcing the heater to run almost continuously, in an attempt to maintain the required temperature.

Also, since an electric tankless water heater doesn’t run continuously, it will only draw less energy, which increases its lifespan continuously. If your home has space limitations, then a tankless water heater is the best choice. Since they don’t have a storage tank and only heat the required quantity of water, they save a considerable amount of space, as compared to their traditional counterparts. In a nutshell, the biggest benefits of choosing a tankless water heater over the others are endless hot water supply, saving space, energy efficiency, longevity, and durability, as well as high resale value.

How to Choose the Best Electric Tankless Water Heater 2018

When it comes to choosing the best electric tankless water heater, you have minimal room for error. Unlike the traditional water heaters that come with a water reservoir, a tankless unit doesn’t have this provision. In short, if it doesn’t have sufficient capacity to heat water that passes through it, then it will not meet your needs adequately. Therefore, the water reaching the tap will not have the required amount of heat. You, therefore, need to be careful when buying one. Having said that, here are some of the factors to consider when buying a tankless electric water heater. Amazon has a list of Tankless Water Heaters

– Energy Efficiency

Energy efficiency remains one of the biggest benefits when it comes to tankless units. Therefore, it should be among the key considerations when buying a unit that can serve your needs. You need to remember that energy savings and energy efficiency of tankless units reduce as the size of the household increases. The good news is that a tankless water heater will still outperform a traditional one when it comes to energy efficiency, regardless of the household size. When it comes to measuring the unit’s energy efficiency, take a closer look at the Efficiency Factor (EF). The best electric tankless water heater should have an EF rating of .92 to .96, which translates to an efficiency of 92% to 96%.

– Warranty

Technical devices are prone to issues. Therefore, you need to select a unit from a reputable company. Warranties range from model to manufacturer. Most manufacturers require the buyer to register the unit and ensure professional installation before it can qualify for warranty coverage. It is advisable to compare warranties offered by the different manufacturers and go through reviews left behind by buyers. Any manufacturer that offers a reasonable warranty for their product means that they believe in the reliability and quality of whatever they are offering. On the other hand, most manufacturers offering a small warranty window means their products are highly susceptible to mechanical issues.

– Size and Flow Rate

Size and flow rate are key considerations when buying the best tankless electric water heater 2018. They determine the amount of water the unit can deliver at one time. Manufacturers size these units based on the temperature rise required to achieve a certain flow rate. Some models of tankless water heaters are specifically designed for a large household with multiple applications while the smaller models are suitable for single household units. You can choose a multiple or single unit, depending on the water points in your home. Alternatively, you can still use your normal water tank and then use the tankless water heater to deliver water to a specific place such as a shower. It all depends on how much hot water you require in your house.

– Cost

Cost is also a vital consideration whenever you are buying a tankless water heater. Without your purchasing power, you may not be able to get the unit you need. However, with so many manufacturers and models of these units on the market, the chances are high that you will find one that meets your budget. However, don’t compromise on the quality for a lower cost.

Bottom Line

When it comes to electric tankless water heaters, every home is unique. No single size or model can fit all applications. Therefore, whenever you are buying one, you need to consider the size of your household, as well as your hot water demand. What works for your friend living in a warmer climate may not work for you if you live in a cold climate. With those considerations in mind, it is easy to find one that meets your needs and fits your budget.

Unlike conventional water heaters, tankless models are energy efficient, space saving, and durable. They will also increase the value of your home, thanks to its energy efficiency. Any of the above electric tankless water heaters can provide you with an endless supply of hot water, whenever you need. As much as these water heaters have a high installation cost, the energy savings in the long term will justify that price. Invest in one today and enjoy the benefits of these water heaters.
