What Is a Tankless Water Heater?
A tankless water heater, also known as a demand-type water heater, is a revolutionary appliance that provides hot water on demand without the need for a storage tank. Unlike traditional water heaters that store and continuously heat a large amount of water, tankless water heaters heat the water as it passes through the unit, providing instant hot water whenever you need it.
One of the key benefits of a tankless water heater is the elimination of standby heat loss. With traditional water heaters, heat is constantly radiating from the stored water, even when you're not using it. This results in wasted energy and higher utility bills. In contrast, tankless water heaters only heat the water when it's needed, making them significantly more energy-efficient.
In addition to their energy-saving features, tankless water heaters also have a longer lifespan compared to standard storage water heaters. While traditional water heaters typically last 10-15 years, tankless models can last up to 20 years or more with proper maintenance. This longevity makes them a cost-effective investment in the long run.
“Tankless water heaters provide instant hot water on demand, eliminating the need for a storage tank and reducing standby heat loss.”
Whether you're looking to upgrade your existing water heater or are building a new home, considering a tankless water heater is a wise choice. Its efficient design, instant hot water capabilities, and extended lifespan make it a popular option for homeowners seeking a reliable and energy-saving solution.
The Right Size Tankless Water Heater
Choosing the right size tankless water heater is crucial for optimal performance and efficiency. The size of the water heater is determined by the flow rate and the temperature rise required for your household's hot water needs.
To determine the flow rate, consider all the hot water devices in your home that may be used simultaneously. Calculate the total gallons per minute (GPM) needed to ensure an adequate supply of hot water.
The temperature rise is the difference between the incoming water temperature and the desired water temperature. This is typically around 120°F for most households. By calculating the temperature rise, you can ensure that the tankless water heater has the capacity to heat the water to the desired temperature.
Flow Rate Calculation Example:
Let's say you have a showerhead with a flow rate of 2 GPM and a kitchen faucet with a flow rate of 1.5 GPM. If you want to use both simultaneously, the total flow rate required would be 3.5 GPM.
Temperature Rise Calculation Example:
If the incoming water temperature is 60°F and you desire a hot water temperature of 120°F, the temperature rise would be 60°F.
Hot Water Device Flow Rate (GPM) Showerhead 2 Kitchen Faucet 1.5 Total 3.5
In this example, you would need a tankless water heater with a minimum flow rate of 3.5 GPM and the ability to provide a temperature rise of 60°F to meet your hot water requirements.
By considering the flow rate and temperature rise, you can select the right size tankless water heater that will efficiently meet your household's hot water demands.

Tankless vs. Tank Water Heaters
When it comes to choosing a water heater for your home, you may be torn between a tankless water heater and a traditional tank water heater. Both options have their pros and cons, and understanding the differences can help you make an informed decision.
One of the biggest advantages of tankless water heaters is their energy efficiency. Unlike tank water heaters that constantly heat and store water, tankless models only heat water as it is needed. This means they are not wasting energy by keeping a large volume of water hot all the time. According to Energy.gov, tankless water heaters can be up to 34% more efficient than traditional tank heaters.
On the other hand, tank water heaters may have a higher standby heat loss because they are constantly heating and reheating a large amount of water. This can result in wasted energy and higher utility bills. However, newer tank water heaters are becoming more energy-efficient with improved insulation and heat retention features.
Size and Lifespan
Tankless water heaters are compact and take up less space compared to tank water heaters. This is because they do not require a large storage tank. The smaller size makes tankless water heaters a great option for homes with limited space.
In terms of lifespan, tankless water heaters typically last longer than tank water heaters. Tankless models can have a lifespan of 20 years or more, while tank water heaters may need to be replaced every 10 to 15 years. The longer lifespan of tankless water heaters can result in cost savings in the long run.
One of the main considerations when choosing between a tankless water heater and a tank water heater is the upfront cost. Tankless water heaters tend to have a higher upfront cost compared to tank water heaters. This is because they require specialized installation, such as upgrading the electrical system or installing additional venting for gas-powered models.
On the other hand, tank water heaters are generally more affordable in terms of upfront costs. They are widely available and have simpler installation requirements. However, it's important to consider the long-term energy savings and potential lifespan of a tankless water heater when evaluating the overall cost.
Tankless Water Heaters Tank Water Heaters Energy Efficiency Highly efficient, up to 34% energy savings Potential standby heat loss, lower energy efficiency Size Compact and space-saving Requires a larger storage tank Lifespan 20+ years 10-15 years Upfront Costs Higher upfront investment More affordable
Ultimately, the decision between a tankless water heater and a tank water heater depends on your specific needs and priorities. If energy efficiency and long-term savings are important to you, a tankless water heater may be the best choice. However, if upfront cost and simplicity of installation are your primary concerns, a tank water heater may be more suitable. Consider the size of your household, daily hot water needs, and available space when making your decision.
Tankless Water Heater Buying Guide
When it comes to choosing the right tankless water heater for your home, there are several factors to consider. Understanding these factors will help you make an informed decision that meets your specific needs.
