tankless water heater myths

Over the years, some misconceptions about water heaters have emerged. Despite being based on outdated information or inaccurate assumptions, these myths can spread and become part of the public discourse. So, if you are planning to install a tankless system but are hesitant because of these tankless water heater myths, you should read the following list to know why they are just that – myths.

We will debunk seven common tankless water heater myths and explain why they are unfounded. Read the facts and details about their effectiveness, performance, and efficiency to make an informed decision on your next water heater installation.

Myth 1: They Take Too Long to Heat Up

Tankless water heaters have a much quicker response time than tank-style models, providing hot water on demand and within seconds of turning on the tap. Even though they do not provide instantaneous hot water, tankless models heat the water rapidly and provide a continuous stream of hot water.

The delay (usually between 2-5 seconds, depending on the water temperature and flow rate) is due to the process of heating the water, which requires a few moments to reach your desired temperature, and also the distance between the device and the faucet. So while there is a slight delay, tankless water heaters take little time to heat up.

Myth 2: They are Expensive to Operate

This myth is due to a couple of the following reasons:

  • Tankless water heaters are more expensive to purchase than tank-style models.
  • There is a perception that they use more energy since they heat water on demand and are constantly running.
  • It is thought that installing a tankless requires extensive revisions to your home’s plumbing setup, which adds to the cost of both material and labor.

But the reality is that they are more energy-efficient and cost-effective than traditional storage tank models because they only heat the water when needed. This means you save money by not heating and storing hot water for periods when you don’t need it. Additionally, the installation costs are usually on par with those of a tank-style water heater, and you can recoup those expenses in energy savings over time.

Myth 3: Their Capacity is too Small for Large Families

This myth may have been true in the past when tankless water heaters first came out, but with advancements in technology and sizing options, this is no longer the case. Tankless water heaters have a maximum output of up to 5-6 gallons per minute, which is enough for the needs of an average family. There are also larger units available that can handle higher demands.

And even with multiple showers running simultaneously, tankless water heaters can provide a sufficient amount of hot water while still being more energy-efficient than traditional models. In addition, they can heat water quickly on demand, so there’s no need to wait for hot water when you have multiple people in the house.

Myth 4: They are Complicated to Operate and Maintain

Tankless models require some maintenance, but they are not complicated to operate. They are easier to maintain than tank-style water heaters, as they don’t have the same sediment build-up common in traditional models. Additionally, they are designed with modern features that make them easy to use and maintain.

Furthermore, tankless water heaters come with user-friendly manuals explaining their features and offering advice on maintaining them. And, if you have any problems with your tankless model, you can quickly contact Danika for water heater repair.

Myth 5: They Overheat Water to an Unsafe Temperature

This fallacy is entirely false. Tankless water heaters provide hot water on demand and have temperature control settings that allow you to set the temperature you want. This means that the water will never be too hot or cold; it will always be just right. They are well equipped with a thermostat that regulates the water temperature and adjustable settings that let you set the maximum temperature for safety.

When the water temperature exceeds the set limit, the tankless water heater will automatically shut off to avoid dangerous temperatures. And if you ever decide that you want your hot water to be hotter, all you have to do is adjust the settings.

Myth 6: All Tankless Water Heaters are the Same

Out of all of the tankless water heater myths, I’m sure you can guess the answer to this one. The truth is that tankless water heaters come in various sizes, styles, and models, each designed for different needs and applications. Some are simpler models with essential features, while others have more advanced features such as digital displays and remote controls.

Before selecting the unit suitable for your family’s needs, you must consider key parameters such as the size of your home, number of occupants, usage patterns, desired water temperature, and local climate. Many manufacturers also offer their models with specific features and capabilities, so it’s important to do your research and compare different models.

Myth 7: Tankless Water Heaters Require a Lot of Repairs

Like any other household appliance, tankless water heaters require some essential maintenance and care. Still, they are designed to be very reliable and require fewer repairs than traditional tank-style models.

Most repairs are usually minor and involve replacing a part or cleaning the unit. Repairs tend to be more expensive than traditional models, but they are typically not required as often.

Tankless water heaters also tend to last longer than traditional models, with many manufacturers offering warranties of up to 20 years. This means that you will likely enjoy the benefits of hot water for many years before needing to replace your unit.

Overall, tankless water heaters are not only energy-efficient and cost-effective, but they are also reliable and easy to maintain. I hope that we have shed some light on about tankless water heaters myths and that you will now be more confident in making an informed decision about whether or not this type of water heater is right for you.

If you are still unsure, consult a professional plumber who can help you choose the best tankless water heater for your needs. Hopefully, you learned a heap about tankless water heater myths you can now dispel. Good luck with your next water heater purchase or installation.
