Installing an Electric Tankless Water Heater
Why should I get an electric Tankless Water Heater?
Visitors to our website would ask certain questions as to why they should get an electric tankless water heater and what it’s benefits are. First off, we’d say that the best thing about these sort of heaters is that they heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water. Perfect right?
It gets better. Electric tankless water heaters are compact in size, taking up less space than conventional tank-type water heaters. They can virtually eliminate standby losses – energy wasted when hot water cools down in long pipe runs or while it’s sitting in the storage tank.
To us, the main advantage of installing an electric tankless water heater is that they eliminate the extra cost of keeping 40 to 50 gallons of water hot in a storage tank, so you waste less energy.
We have compiled a few things to keep in mind when planning to get an electric water heater and they are as follows;
Tankless water heaters are ideal for homes that do not need multiple hot water sources running at the same time. If you want to multitask with a tankless water heater, consider purchasing a larger unit to make sure there is enough hot water to meet your needs. Additionally, be aware that water temperatures may fluctuate as the heating coils keep up with the output of water.

It is only natural to want to save money, and Energy Star statistics state that a tankless water heater will save you an average of $95 per year compared to an energy-saving conventional water heater that can save you $20 per year. Although that may not seem like large savings, it amounts to approximately $1,500 more saved over a lifetime.
A newer trend among builders and homeowners is to maximize every square foot of a home. Not that there was a ton of wasted space in the past, but spaces such as under the stairs, utility closets, and garage space are now optimized for use. A standard water heater requires several square feet of space both in diameter and in height for it to exist. However, a tankless water heater is wall-mounted and leaves plenty of room for you to use the extra space for storage or other utility. Plus, if you are looking to sell your home and you have a tankless water heater, you have more usable space, which increases the value of your home.
4. Storage Tank Option
Although many people like tankless water heaters because of their lack of tank, it is important to consider whether you want a water storage tank. If you like having instantaneous hot water, or you plan on multitasking, you will want to think about adding a storage tank. Storage tanks vary in size and accommodate a range of needs.
Tankless water heaters have many more parts than traditional water heaters. What does this mean? There is the potential for more repairs and thus more repair costs. You may say “that’s no big deal because the warranty will cover it,” but are you sure? Many companies are not offering warranties on these products because they haven’t been around long enough to know how long they will last, and many manufacturers are out of business before a repair is needed.
