The Airthereal Evening Tide Electric Tankless water heater comes in 3 different sizes to tackle all of your hot water needs. Instead of a set amount of water being stored in your water heater tank, tankless water heaters heat water on demand so you always have hot water. The size is 90% smaller than a traditional water heater and since you don’t have to store the hot water, you can save up to 50% on your water heating utility bill.
