As for the question of “what is the downside of a tankless water heater”, we have done in-depth research to find out the tiniest of the cons. In fact, there is more than 1 downside, and so we need to review them all to be sure you are “armed” with the right information. Read on to learn all the essentials.

Too Big Water Output

The first downside of tankless water heater is the water output it releases. On average, the traditional devices operate 40 to 60 gallons of hot water. It means several people can use hot water for different purposes at the same time. On the contrary, we have analogs without a tank. Such a unit can quickly run out of hot water, and you will have to wait until the required amounts of water get heated again.

Higher Upfront Cost

Another downside to tankless water heater is its cost. It serves much longer than an option with a tank. The difference ranges from 8 to 13 years, and it is surely significant! Due to this reason, the cost of tankless units is much higher compared to the ones with a tank. On average, you will spend about $200-$300 more.

In the meanwhile, give heed to the energy bills! Thanks to a tankless unit, you will save up more of your money. It means you need to make a big investment when you buy a tankless option. Quite soon, it will buy off, and you will understand that your investment was profitable. Simply be sure you use the right fuel type for your region. For example, electricity may be cheaper than gas in your region.

May Take Too Long to Supply Hot Water

The next drawback is not always a real drawback for housekeepers. If you are inpatient, it will become a problem. What do we mean by such a blurred introduction of the issue? We will clarify it straight away.

Water needs time to be heated. The time of heating depends on the unit you use. Not all tankless units can heat water in the blink of an eye. The variants with a tank contain water in a boiler and heat it all the time long. When you turn it on, the water is surely hot. You only need to be sure that there is water in it.

When it comes to a tankless analog, it may take about a minute and sometimes a bit longer to heat the water. One minute is not a problem for patient people. The ones who can wait, find it great trouble. Mind that the newest tankless heaters provide instant heating. Of course, they are more expensive, but they are perfect for impatient people.

Energy Wastes

The fourth possible drawback is the energy waste of a tankless heater. To heat water, your device will consume great amounts of power. Consequently, your energy bill may be quite expensive.

Mind that even if you specify the question to “what is the downside of an electric tankless water heater”, it does not make a great difference. You should know that electric, gas, or propane-fired tankless devices commonly consume a lot of energy.

What is the solution to this issue? You need to look for the units, which allow saving on energy bills. These are energy-efficient options. A tankless option is a better advantage in comparison with the units with a tank. As they don’t have any tanks, the water isn’t heated all the time long in a boiler and the energy use is much lower. In the meanwhile, tankless heaters are more expensive. Besides, you need to check the taxes for a certain source of fuel. Perhaps a gas heater is more profitable than an electric analog.
