Do Tankless Water Heaters Really Work Like They Say?

Tankless water heater

Tankless water heaters have gained popularity for their promise of delivering hot water on demand … But do they?

In this blog post, we’ll discuss some of the pros and cons of these systems. So, let’s dive in and uncover the truth about tankless water heaters!

The instant hot water myth

While tankless water heaters offer many advantages, the notion of instant hot water can be slightly misleading. Unlike traditional storage tank water heaters, which store and continuously heat a large volume of water, tankless systems heat water as it flows through the unit. This means that there may be a brief delay between turning on the tap and the hot water reaching the desired temperature. 

The efficiency advantage

Tankless water heaters offer several significant benefits. One of the most prominent advantages is energy efficiency. Traditional storage tank heaters continuously heat and reheat a large volume of water, even when it’s not being used. In contrast, tankless systems only heat water when there is a demand for it. This “on-demand” heating approach significantly reduces energy consumption and can result in substantial cost savings over time.  And since these units are electric, they are much friendlier to the environment.

The endless supply of hot water

Another advantage of tankless water heaters is their ability to provide a continuous supply of hot water. With a properly sized tankless system, you won’t have to worry about running out of hot water, even during peak usage times. So, the household never runs into the situation of actually emptying the tank of all the hot water and needing to wait for 40-75 gallons of water to heat up. This is particularly beneficial for larger households or homes with high hot water demand.

The longer lifespan

Tankless water heaters typically have a longer lifespan compared to traditional storage tank units. While storage tanks may need replacement every 10-15 years, tankless systems can last up to 20 years or more with proper maintenance. This longevity translates into long-term cost savings and reduced environmental impact.

The potential cons

While tankless water heaters offer many benefits, it’s important to consider the drawbacks. One aspect to keep in mind is the upfront cost. Tankless systems can have a higher initial investment compared to storage tank heaters. However, the long-term energy savings and extended lifespan can actually offset this!  And be sure to check out your local utility for possible rebates on switching to tankless technology.

Another consideration is the flow rate limitations of tankless systems. Depending on the unit’s size and capacity, there may be limitations on the number of hot water outlets that can be used simultaneously. Proper sizing and assessment of your household’s hot water needs are crucial to ensure that the tankless system meets your requirements.

Final thoughts

So, although tankless water heaters may not provide instant hot water in the most literal sense, they offer a range of benefits that make them an appealing choice for many homeowners. A tankless water heater from Weather Master can provide you with efficient and reliable hot water for years to come.
