A tankless water heater provides homeowners with hot water on-demand. Unlike traditional water heaters, tankless models don’t store hot water in a massive container for later use. Instead, they heat water as needed. When a family member turns on the tap for hot water, the tankless water heater is activated. It automatically draws cold water from the plumbing system and runs it through a complicated series of heat exchanger coils. Once the water is heated to the right temperature, it is sent to the respective faucet, ready to use.
This innovative technology heats water instantaneously, so users don’t have to wait for long periods of time, making this appliance a favorite amongst homeowners. The most popular models of tankless water heaters are fueled by propane gas, though some utilize electricity as well. These appliances are also programmed to recalibrate their heat output based on the amount of water homeowners are planning to use. For example, if the demand for hot water is minimal, the tankless water heater will use less fuel to heat the water. If the demand increases, it will adjust the fuel usage and heat settings to maximize efficiency.
