Why Install a Tankless Water Heater?
Installing or replacing a water heating system requires a significant decision about which type of water heater to install, which can impact both daily comfort and long-term utility costs. For many, the transition from traditional storage-tank water heaters to modern, efficient tankless water-heating technology is a welcome change. Understanding how tankless water heaters work and the advantages they offer can help determine whether a tankless model is the right choice for a household or business.
What Is a Tankless Water Heater and How Does It Work?
A tankless water heater differs significantly from a traditional storage-tank water heater. A tankless water heater operates only when hot water is needed at a fixture or appliance. In contrast, a storage water heater maintains a large volume of hot water in its tank at all times, so it’s ready when hot water is needed. Because they heat water throughout the day so it’s ready for immediate use, they are not as energy efficient as tankless models.
With a tankless water heater, when hot water is needed at a plumbing fixture or water-using appliance, cold water enters the unit, and either a gas burner or an electric element quickly heats the water. Once hot water isn’t needed anymore, the tankless water heater will stop heating water. This process ensures a continuous supply of hot water for the household without the need for a bulky storage tank or energy waste.
Benefits of Installing a Tankless Water Heater
There are several significant advantages to installing a tankless water heater. One of the most notable benefits is superior energy efficiency. Since tankless water heaters do not waste energy keeping a large storage tank of water warm and preheated for use, they can significantly reduce monthly water heating costs.
Tankless water heaters also provide the luxury of a nearly endless supply of hot water, since water is heated only as needed as it travels through the unit, eliminating the wait time associated with using up the hot water in a storage water heater and waiting for it to reheat.
Furthermore, their compact, space-saving design frees up room, and they have a longer lifespan than traditional tank water heaters, meaning a property with a tankless water heater installed won’t need replacement as often. Traditional storage water heaters typically last about 10 to 12 years, while tankless ones last around 20.
Signs It’s Time to Replace an Existing Water Heater
People considering upgrading to a tankless water heater may want to wait until it’s time to replace their existing water heater so they can get the most out of their current investment. Common signs indicating that a water heater replacement may be necessary include:
- An old water heater that is nearing or has reached the end of its life expectancy
- A water heater that requires frequent repairs, or a particularly expensive repair on an aging unit
- A water heater that is leaking
- A water heater that is visibly corroded or shows signs of internal corrosion, such as discolored hot water
