While almost every house product has greatly improved over the years, much is still expected with regard to our water heaters. There are still times when we run out of hot water—in the dead of winter, no less—and we have to sustain ourselves through most part of the day, almost chilling to death. Yes, they have become quite inconvenient. That’s why when electric tankless water heaters came along, we immediately think that perhaps the thing we’ve been waiting for a long time has finally arrived.

Tankless electric water heaters are far different from the traditional ones we’ve been using for quite some time. For one, it doesn’t have any tank, so it doesn’t occupy a lot of space. It’s the most ideal heater to use for those who are living in tight dwellings, such as apartments. Second, it produces hot water only when necessary. In the process, it doesn’t waste a lot of energy.

To help you understand more about the concept of energy efficiency, here’s a short explanation. Our conventional water heaters work by heating water first until it reaches the desired temperature, then storing it in the tank. While being stored, the thermostat shuts itself down, so there’s nothing that’s maintaining the heat. The water subsequently begins to cool down. Worse, the more you open the tap, the more outside air gets in, further cooling the water.

Now compare that to the electric counterpart. The water heater includes a sensor, which detects when the water starts flowing. Once it does, it is redirected to a heat exchanger, which then heats the water up before it passes out of the tap. Some exchangers keep themselves on until the water tap is closed, while others are controllable, so they shut off once the water has reached your preferred temperature. Regardless, because water is heated only when the tap is on and the exchangers stop working after the tap is closed, no loss of heat energy happens.

As to its space-saving ability, a tankless electric water heater can be easily fitted near tap systems, so water doesn’t have to travel far before it is heated. In other words, you get hot water pretty quickly.

Tankless water heaters also have long lives, spanning more than 2 decades, if taken care of properly. Further, the absence of tank means less worry on hard scale issues, which normally happen if you have hard water.

Indeed, with tankless electric hot water, you have a better alternative to water heaters that run on gas.
