What is a Tankless Water Heater?
A tankless water heater, also known as an on-demand water heater, heats water directly without using a storage tank. When you turn on the hot water tap, cold water travels through a pipe into the unit, where either a gas burner or an electric element heats the water.
This method guarantees a continuous supply of hot water, removing the need to wait for a storage tank to refill. This modern approach to water heating can be a game-changer for households looking for efficiency and convenience.
How Does a Tankless Water Heater Work?
Unlike traditional water heaters that continuously maintain a reserve of hot water, a tankless water heater only heats water as needed. This is achieved through high-powered burners that quickly heat water as it passes through the unit.
As a result, the water reaches the desired temperature almost instantly, providing hot water on demand. This mechanism can significantly reduce energy consumption compared to traditional models, which continuously use energy to keep a tank of water hot.
Benefits of Tankless Water Heaters
Endless Hot Water
One of the most significant advantages of a tankless water heater is the endless supply of hot water. Whether you have a large family or enjoy long showers, you’ll never run out of hot water.
This feature is especially beneficial in places like Texas, where hot showers are a daily necessity. The ability to have a continuous flow of hot water means no more scheduling showers around water heater recovery times or experiencing cold showers.
Energy Efficiency
Tankless water heaters are more energy-efficient than traditional water heaters because they heat water only when needed, avoiding the standby heat loss that occurs with storage tanks.
This efficiency can result in substantial savings on your energy bills over time. The U.S. Department of Energy states that tankless water heaters can be 24-34% more energy-efficient for households that use 41 gallons or less of hot water per day. This translates to lower utility bills and a smaller environmental footprint.
Space Saving
Without the need for a large storage tank, tankless water heaters are compact and can be installed in various locations. This space-saving feature is ideal for smaller homes or apartments where every square foot counts.
They can be mounted on walls or installed in tight spaces, freeing up room for other uses. In urban areas or homes with limited space, this can be a substantial benefit, making it easier to fit into your existing layout.
Longer Lifespan
Tankless water heaters usually have a longer lifespan than traditional tank water heaters. With proper maintenance, a tankless unit can last up to 20 years or more, whereas a conventional tank heater typically lasts 10-15 years.
This longevity can translate into cost savings over time, as you won’t need to replace the unit as frequently. Investing in a tankless water heater can be a long-term solution that pays off through durability and reduced replacement costs.
Environmental Benefits

However, the long-term energy savings and extended lifespan can offset this initial expense, making it a cost-effective investment over time. Additionally, some regions offer rebates or incentives for upgrading to more energy-efficient appliances, which can help reduce the initial financial burden.
Installation Requirements
Installing a tankless water heater can be more complicated than installing a traditional water heater. It may require upgrading your home’s electrical system or gas lines to accommodate the new unit’s demands, which can add to the overall cost.
Proper ventilation is also necessary for gas models to ensure safety and efficiency. It is crucial to hire a licensed professional to handle the installation, ensuring that all local codes and safety standards are met.
Flow Rate Limitations
Tankless water heaters have a limited flow rate, which means they might have difficulty supplying hot water to multiple fixtures simultaneously. It is important to choose a unit that matches your household’s hot water needs, considering the peak usage times.
For larger households, multiple units or a higher-capacity model may be necessary to ensure a consistent supply of hot water. Consulting with a professional can help you determine the best solution for your specific needs.
Choosing the Right Tankless Water Heater
Sizing Your Unit
Selecting the appropriate size tankless water heater is essential for meeting your household’s hot water needs. Units are rated by their maximum flow rate, measured in gallons per minute (GPM).
To determine the right size, calculate your peak hot water demand by adding up the GPM of all the fixtures you expect to use simultaneously. For example, a shower might use 2.5 GPM, while a dishwasher uses 1.5 GPM. Adding these together will give you a better idea of the capacity you need to ensure consistent hot water flow.
