6 Benefits & Drawbacks of Tankless Water Heaters

6 Advantages & Disadvantages of Tankless Water Heaters

Make the Right Purchase for You

When investing in a new hot water heater for your home, there are many options on the market. Should you go with a traditional water heater and pay to constantly heat water? Or is a tankless water heater a better option? We’ve compiled a list of the benefits and drawbacks of tankless water heaters to help you decide which is best for you and your family.

Pros of a Tankless Water Heater

Save Money & Energy

Tankless water heaters save energy and save you money. Although traditional hot water heaters are insulted, the insulation is not designed to prevent heat loss. To provide on-demand hot water, a traditional hot water heater works to constantly heat the water in the tank. This constant heating can cause the total cost of your energy bills to increase each month. A benefit of purchasing a tankless water heater is fast and convenient hot water with reduced energy usage.

Longer Lifespan

Tankless water heaters feature a longer life cycle when compared to traditional tank water heaters—up to two times longer, in fact. While a traditional water heater has a lifespan of 10-12 years, a tankless water heater can last up to 20 years. If you plan to stay in your home for the long haul, investing in a tankless water heater can save you from a costly replacement down the road.


A 40 to 60-gallon hot water heater takes up a large amount of space in your laundry or utility room. On the other hand, an advantage of installing a tankless water heater is the small form factor. These heaters take up less than half the amount space of a traditional water heater, saving you precious space in your home.

Cons of a Tankless Water Heater

With 40-60 gallons in reserve at all times, a traditional water heater has the capacity to function on a grander level, allowing multiple people to use hot water while showering, washing dishes, and running the washing machine at the same time. A disadvantage of tankless water heaters is the reduced output of hot water. It’s easy to run out of hot water if you operate your dishwasher and shower simultaneously, 

Energy Requirements

Whether you choose an electric water heater or a gas water heater, you need to be aware of the immense output of energy needed upon starting a tankless water heater. Since a traditional water heater has reserves, it uses lower amounts of energy over time to heat its water. A tankless water heater requires a large amount of energy to begin producing the hot water in your household. In some instances, you may need to choose electric over gas, or vice versa, for your tankless water heater depending on how much instantaneous energy is available through your gas or electric connection.

High Upfront Cost

Although a tankless water heater features a longer life cycle, a disadvantage of this type of water heater is its high upfront cost. Depending on which models you compare, tankless water heaters can cost anywhere from $200-300 more than a traditional water heater. But, with the added savings in your monthly energy bill, this additional cost may not affect your purchasing decision.
