Pros and Cons of Traditional vs. Tankless Water Heaters | Ambit Energy

Are Tankless Water Heaters Worth the Investment?

The desire to be energy-efficient in all areas of your home may be the reason you’re considering a tankless water heater. But, is that the best option for you? There are a lot of factors when considering a tankless or traditional water heater. While there are advantages to each, our team at Ambit Energy has compiled a list of the pros and cons of both you can make an educated decision.

Energy Efficiency

The desire to use less energy is the reason most people switch to a tankless water heater. Tankless water heaters provide hot water as needed, which means you’re saving energy by not heating unused water. A traditional storage water heater keeps the water in a tank until it’s ready to be used, which may not be energy efficient, but you have water available when needed.

Size and Production

If you compare the size of the two heaters, there’s a difference in space savings. The storage water heater is generally around 60” tall and 24” wide. A tankless water heater, in comparison, can be as small as 28” tall and 20” wide. The space savings is as significant as their outputs. A traditional water heater can hold 40-60 gallons of hot water at a time. Because of it’s size, you can expect a tankless water heater to only produce 2-5 gallons a minute.


Traditional water heaters are less expensive than tankless. The average price of a traditional water heater is between $300-$600. While the price of a tankless water heater starts, on average, at $1,000. However, the common belief is that you’ll make up the difference in the amount of energy you save and the length of time you’ll own the heater. Storage water heaters can last from 10-15 years; tankless water heaters can last as long as 20 years.

There are significant advantages to each water heater. However, consider the size of your home and average demand when making your decision. Your hot water needs might outweigh the long-term investment.
