What is a Tankless Water Heater?
When considering how much it is to upgrade to a tankless water heater, it’s essential to understand how this type of system revolutionizes home water heating. A tankless water heater, often called an on-demand or instantaneous water heater, differs from conventional tank water heaters by heating water only when needed. This approach brings greater efficiency and can offer substantial long-term savings on energy bills, not to mention the luxury of endless hot water whenever you turn on the tap.
Overview of Tankless Water Heaters
Tankless water heaters work by heating water directly as it passes through the unit, rather than storing gallons of preheated water in a tank. When you open a hot water tap, cold water travels through a pipe into the heater, where either a gas burner or an electric element instantly warms it. The process continues for as long as water is being demanded, providing hot water continuously until the tap is turned off. With no need for a storage tank, tankless water heaters take up far less space and eliminate the risk of running out of hot water mid-shower.
How Tankless Systems Differ from Traditional Tank Water Heaters
Traditional water heaters maintain a large tank of water, continuously heated to a set temperature. This “standby” heat, even when water isn’t actively being used, can waste energy. Tankless systems, in contrast, produce heat only when hot water is needed, reducing energy waste and significantly lowering monthly utility bills. Additionally, tank models typically have a lifespan of about 10-15 years, while tankless heaters often last up to 20 years or more with proper maintenance.
