Things To Consider When Buying A Tankless Electric Water Heater
Just like any product on the market, buying a tankless electric water heater entails a lot of considerations as well. This is because there are several factors that affect the overall quality and functionality of the water heater.
Learning these factors will further help you in your search. So, you better watch out these things primarily before making a decision and heading out to make a purchase.
1. Standard Water Temperature In Your Area
In every region or area, there is a distinct water temperature. And you have to know the average temperature of the incoming water in your location. By learning these ratings, you can effectively know whether having an electric water heater is a great option for you or not.
It is important for you to note that tankless electric water heaters are much more effective and efficient when these heaters do not need to increase the temperature above 30 degrees Fahrenheit.
Now, if you are residing in the southern part of the United States of America, then having a tankless electric water heater is a great choice more than the other types of heaters.
2. Water Flow Rates and Demands
Alongside the average water temperature in your area, another thing that you have to regard is the water flow rate demands.
Where do you intend to utilize and connect the electric water heater
? Are all of the water outlet line in your property will be connected to the water heater?
Understanding and knowing the demands will help you know what size and capacity of a tankless electric water heater you will be needing. Keep in mind that the larger the demand, the larger the capacity that you will need. And this could mean much more expensive costs.
3. Durability and Build
Generally, tankless water heaters are not really cheap. In fact, they may require you to shell out a few thousand bucks. Accordingly, it is only appropriate that you regard the durability and build of the tankless electric water heater that you are choosing.
The first tankless water heaters actually utilize metals as the main materials in the construction. And these kinds of materials usually need more maintenance since there is always a recurring limescale build-up.
Fortunately today, the newer generations of tankless water heaters are made from the finest qualities of materials that no longer need rigorous maintenance processes. But, you must expect that these units may cost much more.
Nevertheless, the lesser the maintenance processes, the more the unit is convenient and cost-effective to the users in the long run.
4. Overall Size
For homeowners who have a small space or rather a small shower room, the typical choice of water heaters are the smaller ones. Apparently, there are tankless electric water heaters that are portable and compact.
Some would also prefer to have this due to the space and area that it can save. And sometimes, these portable and small sizes would cost much less than the average sizes.
Even so, the preferred size and dimensions of the tankless electric water heater would depend on the user’s preference. And if you are considering this aspect, you might want to check the exact space and size of the area where you will install the unit.
Tankless electric water heaters, as mentioned, are not entirely cheap. As a matter of fact, they are normally considered as investments. But while this is a necessity for others, these water heaters would cost more than $500 on an average note.
Also, the total price of each unit varies depending on the features, capacity, functionality, and, certainly, the brand.
So, before you make your purchase, ensure that you consider all the underlying factors that could affect both the quality and the price of the water heater unit.
