Benefits of Tankless Water Heaters
When you upgrade to a tankless water heater in your Phoenix home, you’ll experience a superior hot water experience while reducing energy usage. There are many types of tankless water heaters, all of which can offer benefits to your hot water supply. The benefits of installing a tankless water heater include:
Endless Hot Water: By far the most notable difference with a tankless system is there’s no lag in waiting for hot water, and it never runs out. “Using up all the hot water” is a thing of the past.
Smaller Footprint: Tankless systems take up about as much space as a piece of carry-on luggage, and can fit more easily in closets, crawlspaces, and even outside the home, saving valuable space compared to tanked units that need space to hold an average of 40-50 gallons of water.
Energy Efficiency: Traditional water heaters expend costly energy keeping dozens of gallons hot. By heating water on demand, a tankless system eliminates standby heat loss, saving on average 30% on your household energy use, and on your energy bills.
Increased Lifespan: A tankless system can last over 20 years with proper maintenance and upkeep, over twice the longevity of a traditional tank water heater. Traditional water heaters last around 6 to 10 years (depending on water quality and frequency of use) all while declining in efficiency as they age. In many cases, the longevity of tankless units alone help offset their price in the long run.
Improved Water Quality: Because tankless systems don’t store water, there’s no risk of sediment or bacteria build-up that can come out from the hot water tap. If you’re experiencing discolored or rusty water, a deteriorating water tank might be the culprit.
Lower Risk of Leaking and Water Damage: Minerals and sediments collecting at the bottom of a traditional water heater can corrode the metal and seals, and a rupture can spill up to fifty gallons of (potentially hot) water throughout your home. With less standing water, a tankless unit hinders corrosion, sediment buildup and bacterial growth.
Whether you’re upgrading or replacing your tankless water heater system, or if your current system needs repair or routine maintenance, call Goettl for the best service experience in the greater Phoenix community.
