Pros and Cons of Tankless Water Heaters: Making an Informed Decision

Feeling hot under the collar from your clunky old water heater?

A tankless water heater is one of the longest-lasting, most efficient ways to heat the water in your home.

Imagine never having to worry about cold showers or waiting for the water to heat up again. With a tankless water heater, you can enjoy endless hot water on demand, transforming your daily routine and making your home more comfortable and efficient.

We’re about to reveal the five must-know pros and cons of tankless water heaters that’ll have you basking in endless hot water in no time.

How Tankless Water Heaters Work

First things first, let’s take a look at how tankless water heaters work. Traditional storage tank water heaters keep heated water inside an insulated tank until it’s used.

Tankless water heaters don’t store hot water like traditional hot water tanks. Instead, they instantly heat cold water as it passes through using an electric or gas burner. This eliminates the need for a storage tank, resulting in a more compact and energy-efficient system.

Pros of Tankless Water Heaters

Now that we’ve got the basics covered, let’s consider some of the pros associated with investing in a tankless water heater.

Endless Supply of Hot Water

Tankless equals endless. No more worrying about cold showers or baths when someone else has used hot water. These units deliver a continuous flow of hot water, ensuring you never run out when you need it the most.

Lower Energy Bills

Times are a-changin’, and so should your water heater. Tankless water heaters are a great choice for saving money on monthly utility bills. They use up to 50% less energy than storage tank models!

Tankless heaters heat water on demand, meaning you only use energy when you need hot water. This can lead to lower utility bills, making an impact on both your wallet and the environment.

Space-Saving Design

Tiny homes rejoice! Tankless water heater features include a compact design that frees up valuable space in your home. No more bulky tanks taking up your precious real estate! These modern units can be installed in tight spaces or mounted on walls for optimal convenience.

Longevity and Lower Maintenance

Goodbye, maintenance woes! Built to last, tankless water heaters usually have longer lifespans than traditional models. If properly maintained, tankless water heaters can last up to 20 years, twice as long as a traditional storage tank.

They also require less maintenance, meaning fewer headaches and more time for the things that matter most.

Customizable Options for Your Needs

One size does not fit all. Tankless water heaters are available in various types, sizes, and fuel sources, ensuring you find the perfect fit for your home, water heater budget, and unique requirements.

Professional tankless water heater installation ensures your new unit is tailored to your specific demands.

Greater Security

Tankless water heaters provide greater security against unexpected mishaps. They can’t burst open like traditional storage tanks, which can cause extensive damage to your home.

With no reservoir of stored water, tankless water heaters are also much less likely to experience flooding or other damage in the event of a natural disaster.

Improved Water Quality

Tankless water heaters provide a steady flow of hot water, meaning you don’t have to worry about the water sitting in the tank and becoming stagnant. This can result in improved water quality with fewer contaminants and impurities.

Cons of Tankless Water Heaters

Like everything, there are some drawbacks associated with tankless water heaters. Consider these potential disadvantages before taking the plunge.

Initial Investment

A tankless water heater is more expensive than a traditional storage tank model, with prices ranging from $1,000 to $3,000 for the unit alone, not including installation costs. However, the long-term energy savings can often offset this initial investment.

Weigh the upfront costs against the potential savings over time to determine if a tankless water heater is right for your home.

Lower Flow Rates

Tankless water heaters do have flow rate limits. This means it may be unable to supply enough hot water for multiple tasks at once, such as running the dishwasher and showering.

This can lead to fluctuating water temperatures or a decrease in water pressure. Sometimes you may be unable to use two fixtures at the same time.

To avoid this issue, you may need to install multiple tankless units or invest in a larger capacity model, which could increase the overall cost. Professional technicians can help you find the right size tankless water heater.

For those who require greater hot water with multiple simultaneous uses (such as showers, laundry, and dishwashers), a traditional hot water tank may be a better option. The initial cost of a tankless system could be higher, but the long-term energy savings may offset this investment.

Longer Wait Times for Hot Water

Hot water may take a few extra seconds to reach the tap when using a tankless water heater. This is due to the fact that the water needs to be heated to the right temperature on demand.

Although this isn’t a major issue, it may become annoying when needing hot water in a hurry.


As with home appliances, tankless water heaters require regular maintenance and cleaning for optimal performance. Mineral buildup from hard water can reduce efficiency and eventually cause system failure if not addressed. It’s recommended to perform annual descaling and flushing to remove mineral deposits from the heat exchanger.
