When it comes to water heaters, there are two main options: traditional tank-style or tankless. Tankless water heaters have been gaining popularity in recent years due to their energy efficiency and convenience.
However, is a tankless water heater the best choice for your home? In this blog, we’ll explore the pros and cons of a tankless water heater, so you can make an informed decision when it comes time to upgrade.

Pros
Energy Efficiency
Tankless water heaters are more energy-efficient than traditional tank-style water heaters because they only heat water as needed.
This means they do not have to store hot water, which can lead to standby energy loss. According to Energy.gov, tankless water heaters can be up to 34% more energy-efficient than tank-style heaters. This can result in significant savings on your energy bills over time.
Longer Lifespan
Tankless water heaters typically last longer than tank-style heaters. According to Consumer Reports, a tankless water heater can last up to 20 years with proper maintenance, while a tank-style heater will typically last around 10-15 years.
This means you will not have to replace a tankless water heater as often, saving you money in the long run.
Space-Saving
Tankless water heaters are much smaller than traditional tank-style heaters. This means they can easily fit in tight spaces, such as a closet or utility room. This is especially useful for small homes or apartments where space is limited.
Endless Hot Water
Tankless water heaters can supply endless hot water since they heat water on-demand. This means you will never run out of hot water during a shower or bath. This can be beneficial for households with large families or frequent guests.
Cons
Higher upfront cost
Tankless water heaters cost more upfront than traditional tank-style heaters. According to HomeAdvisor, the average cost of a tankless water heater installation ranges from $1,800 to $5,000, while a traditional tank-style heater averages around $1,000 to $1,500.
Complexity
Tankless water heaters are more complex and may require a professional installation. This can be costly and time-consuming if you are not handy.
Limited Flow Rate
While tankless water heaters can supply endless hot water, they are limited by their flow rate. If you have multiple appliances or bathrooms using hot water simultaneously, the flow rate may not be enough to supply hot water to all of them.
Cold Water Sandwich Effect
One potential drawback of a tankless water heater is a phenomenon called the “cold water sandwich” effect. This occurs when the heater turns off and cold water enters the hot water line before the heater turns back on. This can lead to a brief moment of cold water during use.
In conclusion, tankless water heaters offer many benefits such as increased energy efficiency, space-saving, and endless hot water supply. However, they do have some drawbacks, including higher upfront costs and limited flow rates.
When deciding if a tankless water heater is right for you, weigh the pros and cons and consider your household’s hot water needs and budget. With proper maintenance and installation, a tankless water heater can be a great investment for your home.
