Tankless Water Heaters, also called Instantaneous Water Heaters, heat
water as it flows through the device, and does not retain water
internally except for what remains in the heat exchanger coil.
The advantages of a Tankless Water Heater are many: longer life,
increased storage space, lower cost, and an endless torrent of hot
water.
