Tankless water heaters can be one of the best investments you can make for your family’s comfort and convenience. Although they do have a larger upfront cost, you can save money with a tankless system the longer you stay in your home. If you’re considering making the switch from a traditional tanked water heater to a tankless water heater for your home, we at Shafer Services Plus, a water heater service company, have 5 reasons that may help you decide.


1. Takes Up Less Space

One of the primary advantages of a tankless water heater is its compact size, which offers homeowners a range of practical benefits. Unlike traditional tanked water heaters that require a significant amount of space to accommodate the large tank, tankless water heaters are much smaller and more streamlined in design. This compact size opens up a world of possibilities for installation, allowing you to optimize the space in your home.

  • Installation Variety

With a tankless water heater, you have the flexibility to mount it on a wall in various locations, such as your garage or even in a laundry room. This strategic placement ensures that hot water is readily available in areas where it’s frequently needed, minimizing the distance between the heater and the points of use. By eliminating the need for a bulky tank, tankless water heaters can seamlessly blend into the existing layout of your home without causing any disruption to your living space.

  • Wall-Mounted Convenience

Moreover, the ability to mount a tankless water heater on a wall brings convenience and accessibility to maintenance and servicing tasks. Unlike tanked water heaters, which often require a dedicated utility closet or basement area, a tankless unit can be easily accessed for routine check-ups, repairs, or inspections. This accessibility simplifies the maintenance process, ensuring that your tankless water heater remains in optimal condition for years to come.

2. Provides Endless Hot Water

One of the most significant advantages of a tankless water heater is its ability to provide a continuous supply of hot water, eliminating the frustration of running out of hot water, especially during peak usage times. This transformative feature brings convenience, comfort, and efficiency to your daily routines, making it a compelling reason to consider a tankless water heater for your home.

  • On-Demand Comfort

Unlike traditional tanked water heaters that store a finite amount of hot water in a large tank, a tankless water heater operates on demand. When a hot water tap is opened, cold water enters the unit and passes over heating coils or a heat exchanger, rapidly raising the temperature to the desired level. This instantaneous heating process ensures that hot water is available whenever you need it, without the need to wait for the tank to refill or reheat.

The absence of a storage tank means that you no longer have to worry about depleting the available hot water supply. Whether you’re taking a long shower, running multiple appliances simultaneously, or tackling various household tasks, a properly sized tankless water heater can accommodate the demand. This consistent and endless supply of hot water allows for multiple uses throughout your home without any interruption or compromise in performance.

  • Luxury Flow Assurance

Moreover, the ability of a tankless water heater to meet the demands of high-flow fixtures and appliances, such as luxury showers or whirlpool tubs, is an added advantage. These fixtures often require a significant amount of hot water to maintain optimal performance. With a tankless water heater, you can indulge in the luxury of these features without worrying about inadequate hot water supply, as the unit can deliver the required flow rate and temperature consistently.

  • Temperature Control

In addition to providing endless hot water, a tankless water heater offers precise temperature control. Modern tankless models often come with digital controls that allow you to set and maintain the desired water temperature with precision. This level of control ensures that you can tailor the hot water output to your specific preferences, whether you prefer a scorching hot shower or a lukewarm temperature for delicate tasks.

3. More Energy Efficient

Energy efficiency is a critical consideration when selecting a water heater, as it not only contributes to cost savings but also reduces environmental impact. Tankless water heaters excel in this regard, offering significant energy-saving benefits compared to traditional tanked models. 

  • Reduced Energy Usage

As mentioned earlier, tankless water heaters operate on-demand. They only heat water when it’s needed, eliminating the need for continuous energy consumption to maintain a standing supply of hot water. This fundamental difference in operation immediately translates to reduced energy usage.

  • Less Heat Loss

By providing hot water on-demand, tankless water heaters eliminate standby heat loss. Standby heat loss refers to the energy wasted when the stored hot water in a tank gradually loses heat over time. With tanked water heaters, this heat loss occurs even when no hot water is being used, resulting in unnecessary energy expenditure. In contrast, tankless water heaters bypass this inefficiency entirely, ensuring that you only consume energy when hot water is actively being used. This precise heating mechanism optimizes energy usage, leading to substantial savings on your energy bills.

  • Benefits Irregular Hot Water Usage

The elimination of standby heat loss is particularly beneficial for homes with irregular or infrequent hot water usage patterns. For instance, if you frequently travel or have periods where hot water consumption is minimal, a tanked water heater would continuously maintain the temperature of the stored water, even during extended periods of non-use. This constant energy consumption can be wasteful and costly. However, a tankless water heater adjusts its heating output in real-time, only expending energy when hot water is being actively utilized. As a result, you won’t pay to heat water that’s not used, ensuring efficient energy utilization and maximizing cost savings.

  • How Professionals Can Help

It’s worth noting that the energy efficiency of a tankless water heater is also influenced by proper sizing and installation. Consulting with a professional water heater installation company ensures that your tankless water heater is appropriately sized for your home’s hot water demands, optimizing its efficiency and performance. Additionally, routine maintenance by professionals can help ensure that your tankless water heater operates at peak efficiency over its lifespan.

4. Longer Functionality

Investing in a tankless water heater can provide you with long-term benefits. When properly sized for your home and installed and maintained by a professional tankless water heater service provider, tankless water heaters can last twice as long as conventional tanked versions. While tanked water heaters typically have a lifespan of up to 10 years, tankless water heaters can usually last double that time. If you plan to stay in your home for a long while, this can be a financially sound investment. By choosing a tankless water heater, you can enjoy a long tankless water heater life for many years without worrying about frequent replacements or repairs.

5. Reduced Risk of Leaks and Damage to Your Home

Water leaks and the resulting damage can be a homeowner’s worst nightmare. Traditional tanked water heaters have a higher risk of leaks due to the storage tank holding a large volume of water. With a tankless water heater, this risk is significantly reduced. Since there is no water holding tank and the unit can be located outside, homeowners eliminate the risk of their tankless water heater leaking. Additionally, without proper maintenance, tanked water heaters run the risk of explosion, a dangerous and costly occurrence that no homeowner wants to experience. This risk can be completely avoided by opting for a tankless water heater. 


Switching to a tankless water heater for your home can provide numerous benefits, including space-saving, endless hot water supply, energy efficiency, extended functionality, and reduced risk of leaks and damage. If you’re thinking of a new tankless water heater installation, it’s important to talk to a professional about the best type and size for you as well as tankless water heater financing. Some tankless water heaters even come with WiFi control options, adding an extra level of convenience to your daily life. When you seek professional advice on your installation, you’ll know exactly what solution is best for your needs and home.
