If your old water heater is causing problems, you may be thinking about replacing it with a tankless water heater. That’s a very wise decision for many homeowners. However, as efficient and convenient as tankless systems are, they are not necessarily the right water heater solution for everyone.
Read through the pros and cons of tankless water heaters, and decide for yourself if an on-demand water heater is the right choice.
How Tankless Water Heaters Work
Tankless water heaters are available in many sizes. Small point-of-use models heat water for a single application, such as a bathroom sink or dishwasher. Large whole-house models are powerful enough to provide hot water on demand for clothes washing, showering and more. Whichever size you choose, tankless water heaters heat water inside a heat exchanger as hot water is called for from a tap or appliance.
Efficiency: Tankless Vs. Storage
One of the most popular advantages of going tankless is that tankless water heaters are more energy efficient than storage water heaters of the same fuel source (e.g. gas vs. gas). Generally speaking, households that use less than 40 gallons of hot water a day will save a higher percentage of energy with a tankless water heater.
However, a large household that uses several dozens of hot water a day can save substantial energy by installing a network of smaller point-of-use tankless units.
Installation costs are another factor specific to each home. If you’re able to install a tankless system in the same place of your old storage model without any modifications to electrical or gas lines, the cost of labor will be about the same. However, the purchase cost of a tankless model is higher than a conventional water heater.
On a positive note, maintenance and repair costs for tankless systems are substantially less than storage systems. Moreover, tankless water heater are designed to last 20 years or longer — more than twice the lifespan of a typical storage water heater.
