What is an on-demand hot water heater?
A tankless water heater only heats water when you need it, which is why they are often called “on-demand” hot water heaters. Since these energy efficient water heaters don’t store heated water, they start to work only when you open a hot-water tap (such as for a shower) or begin using an appliance (like the dishwasher or washing machine). The tankless water heater recognizes the need for hot water and starts the heating process. Instead of waiting for minutes for the hot water to begin flowing as you would with a traditional tank water heater, your hot water arrives much faster. It can save you time, money and wasted water.
