Electric Tankless Water Heater – Electric Tankless Hot Water Heater Reviews
What is an electric tankless water heater?
A tankless electric water heater (also called instantaneous, instant or on-demand electric water heater) is a tankless water heater that is powered by electricity as oppose to instant gas water heater which is powered by gas.
This type of water heaters instantly heat water once the hot water tap is turned on because turning on the hot water tap is the signal to the unit to start the process of water heating. Also, the process of water heating lasts for as long as the hot water tap is on.
In other words, the electric tankless water heater would supply you with hot water exactly when you need it and for as long as you need it.
Tankless Electric Hot Water Heater Benefits
Tankless electric hot water heaters save you money, energy and space; provide you with instant and endless volumes of hot water and make you go “green” due to their eco-friendly designs and energy saving features.
Due to the fact that the water is heated only when it is needed and not while you are sleeping, at work or on the vacation the tankless electric water heaters constantly save you energy.
The traditional tank water heater uses a lot of energy to heat the water that is inside the tank. However, very often that water is not used and it cools down, which triggers on the tank water heater to once again use a lot of energy to heat the water… and the process of energy wasting goes around and around.
Since the electric tankless water heater doesn’t retain any water internally, except for what is in the heat exchanger coil, the energy efficiency is much higher than the one of the tank water heater, which directly results in money saving.
Instant hot water and unlimited hot water supply is one of the major electric tankless water heater advantages when it comes to tankless water heater vs. tank water heater comparison.
There is nothing more annoying than waiting for the tank water heater to heat enough of water so that we can take a shower or worse – taking a cold shower because the person that took shower before us used all of the hot water stored in the tank water heater.
Most of the electric tankless water heaters can be mounted on the wall, or placed in small kitchen or bathroom cabinets or even in the building’s structure.
The slim design and the light weight of the tankless electric water heaters can save you much needed bathroom or kitchen space while at the same time making your home look even more luxurious and spacious.
One of the very important electric tankless water heater benefits is the fact that this type of water heaters is “green”.
Meaning it saves energy and natural resources which is why the American government decided to encourage its citizens to buy tankless water heaters by introducing the tax incentives for people that install these great water heaters in their homes or businesses.
Electric Tankless Water Heater Tax Credit
If you think about buying the electric tankless hot water heater you should know that you can save money even before you get your tankless unit installed in your home.
If you decide to buy the Energy Star qualified tankless water heater you can save up to 30% of the tankless water heater cost and its installation.
To find out whether some tankless water heater is energy star qualified or not compare the specific tankless model specifications with the energy star requirements, or you can just ask the salesman whether the on demand water heater model that you are interested in has the Energy Star label or not.
The reason why the government offers the tax incentives and tax credits to the buyers of the energy star qualified products is because those products use less energy, save money and help protect the environment.
