Tankless Water Heater Energy Efficiency

Pros & Cons of Tankless Water Heaters

On-demand (tankless) water heaters have both advantages and disadvantages, just like any other product.


Tankless water heaters generally last 20 to 30 years, which is twice as long as the expected usable life of a storage tank water heater. You’ll have hot water anytime you need it with on-demand water heating, which may be tiny and put in “tight quarters.” The longer a gas-fired tank is in use, the more money it saves the homeowner. Electric tankless water boilers still save around $44 per year on average.


A tankless water heater installation might be expensive if you’re replacing a storage tank water heater with a tankless-type water heater. If you have numerous showers in your home, one of the shower-takers is bound to get a “chilly” sensation. Because of the difficulty of relocating existing pipe, you may need to install a new water heater that is more expensive than a tankless one.

Storage Tank Water Heater Advantages and Disadvantages (Tank) Water Heater


Storage tank water heaters offer a significantly lower starting cost. Storage tank water heaters are easier to run than tankless models, resulting in lower maintenance and repair costs. When these water heaters go down, their less complex design provides for simple, low-cost heating system repair. Repairing and replacing tankless water heaters is more difficult and expensive.


Because of its size, storage tank water heaters might take up more room. If you take numerous showers frequently, you may need a bigger water heater. If you don’t have enough room in your home, you’ll have trouble finding a suitable location for storage tank water heating. Storage tank types have a shorter usable life, generally 10 to 15 years (approximately a quarter of the life of an on-demand water heater). In addition, they must be changed twice as frequently as tankless water heaters.
