Understanding Tankless Water Heaters
What is a Tankless Water Heater?
A tankless water heater, often referred to as an on-demand water heater, is a modern solution to the age-old problem of providing hot water in homes. Unlike traditional water heaters that store and continuously heat a large volume of water in a tank, tankless systems heat water directly as it flows through the unit. This means that you get hot water only when you need it, without the energy waste associated with keeping a tank of water hot at all times. The technology behind tankless water heaters is quite sophisticated, utilizing high-powered burners or electric coils to rapidly heat water as it passes through a heat exchanger. This process not only provides an endless supply of hot water but also offers significant energy savings, as there is no standby heat loss.
