5 Tankless Water Heater Myths Uncovered

Some argue tankless water heaters are effective, others claim they're not. Hopefully, the information here will clear things up.

Because tankless water heaters are fairly new, I can understand the reluctance to buy one. Switching from a tanked water heater to a tankless one is a big decision. We've been relying on tanked water heaters for a long time. They've been a great source of hot water, but if you're in need of a new water heater and you're reluctant to switch, the information in this article should help make it clearer.

There are at least 5 misconceptions surrounding the use and effectiveness of tankless water heaters. My purpose is to expose the fallacies for what they are and help you understand that using a tankless water heater is a great idea.

Myth #1

Most people believe tankless water heaters are expensive to operate. They're not. In fact, using a tankless water heater is considerably less expensive. This type of water heater can save you 20% on your energy bill.

First, it doesn't store hot water that isn't being used, so you're not paying an energy bill based on presupposed use of hot water. Often called on-demand water heaters, this water heater supplies hot water as needed. Tanked water heaters amass hot water inside a large 30-40 gallon tank, keeping it warm 24 hours a day, an unnecessary expense when hot water isn't being use.

Myth #2

Most people are under the impression that a tankless water heater doesn't supply enough hot water. A 40 gallon tanked water heater stores exactly 40 gallons of hot water. Once that water is used, water must be reheated. This can take as long as 30 minutes. Thus, availability is limited.

As long as you need hot water, a tankless water heater will supply it. There's no storage tank. No storage tank means there's no shortage of hot water. Water is heated as it passes over a heating element to an outlet. As long as you need it you'll receive it. Just turn on the tap.

A whole house tankless water heater is designed to supply hot water to a 4-5 persons household. Because water is heated on demand it won't run out, making it possible for more than one person to shower at a time. There's no limit to how much hot water you can use.

Myth #3

It's believed that a tankless water heater heats water to an unsafe temperature. This is a myth because tankless water heaters offer an adjustable thermostat for personalized use. Set the thermostat to meet your needs, and enjoy hot water at just the right temperature.

Just like your tanked water heater, there's a thermostat to prevent overheating and potential scalding. There's no need to worry about your water getting too hot unless you set the thermostat too high. A shower setting should not reach more than 105 ° F. Adjust the thermostat according to your family's needs.

Myth #4

Here, I address the fallacy that tankless water heaters are inefficient. As already indicated, tanked water heaters store hot water for future use. A pilot light keeps it hot. For this reason, tanked water heatersleave a much larger carbon footprint than the tankless variety. Tanked water heaters waste energy. Tankless water heaters don't.

Clean energy at minimal use makes a tankless water heater a great ecological option, so don't assume this water heater will be costly. The truth is it won't. It virtually costs pennies to operate in comparison to your tanked variety. Don't pay to heat water that's not in use.

Myth #5

Some think that a tankless water heater doesn't supply a continuous flow of hot water. It's believed that cold water will occasionally enter the hot water stream. The truth is it doesn't. Because cold water passes over a heating element before it reaches the outlet, you're guaranteed a steady stream of hot water.

Simply turn on the hot water tap and enjoy instant results, this type of water heater heats it before it reaches the outlet. Just because a tankless water heater doesn't store hot water doesn't mean it can't meet the demand.

Benefits of Using a Tankless Water Heater

  • Cost effective: Inexpensive to operate
  • Adjustable thermostat: Heat control
  • Efficient and effective: Supply and demand
  • Space-savers: Fit in small spaces easily
  • Eco-friendly: Small carbon footprint

Environmental Benefits

By now you know that tankless water heaters are environmentally friendly. The fact that tankless water heaters don't store hot water saves energy. In essence, using a tankless water heater cuts back your use of natural resources. Take an environmentally feasible approach and choose to use a tankless water heater.

Tanked water heaters supply hot water, but at what cost? Eliminate your tanked water heater and quit burning precious resources. So if you're rebuilding, buying a home, or simply changing your water heater, then consider an eco-friendly option.

Practical and Functional

A feature making this water heater practical and functional is it's great space-saving design. With this water heater, you don't need to search for a large space to install it. These water heaters fit in small spaces easily. There's no storage closet needed, a useful characteristic anyone can appreciate.

Another practical aspect - these water heaters are ideal for apartments, condos, or houses. They come in a variety of sizes, making it possible to meet your specific needs. Whether you have a small household - 1 or 2 people - or a large household - 4 or more people - there's a tankless water heater you can use.

By now you realize that paying to heat water that's not in use isn't practical. It doesn't make sense to store hot water on a day to day basis. Even when you're out of town, the pilot light warms the water. Clearly, this is unnecessary.

On-demand water heaters aren't energy wasters. They supply hot water as needed, a feature that makes them functional. And because wasting natural resources isn't an option anymore, it's an ideal choice.

The Facts Revealed
