Benefits of Tankless Water Heaters
The benefits of installing a tankless water heater include:
Endless Hot Water: Tankless means limitless. Being able to supply as much hot water as needed is among the biggest differences tankless hot water system owners notice when switching. Pay attention to your water usage if you do switch, it’s easy to get carried away with comfort.
Smaller Footprint: Tankless water heaters save valuable space inside or outside your home. Units range in size from a small backpack to medium-sized suitcase, and are typically wall mounted.
Energy Efficiency: By eliminating standby heat loss, tankless water heaters are more energy efficient, resulting in an average savings of 30% on your household energy use.
Increased Lifespan: Traditional water heaters usually last about 6 to 10 years, while a tankless hot water heaters typically last up to 20 years or more when well maintained. Upkeep is key to seeing the most out of this benefit.
Lower Risk of Leaking and Water Damage: A rupture, seal failure or failed pressure gage on a water heater tank can result in dozens of gallons of spilled water. Tankless water heaters store no water in reserve, vastly reducing the risk of water damage, sediment buildup and corrosion.
