Instant energy savings and endless hot water. Ideal to back up a solar water heating system in cloudy weather, the Aqua Star gives a boost to water temperatures, or stands alone to provide all your hot water needs — automatically. Aqua Star uses the best materials, tests each unit 5 times before it leaves the factory, and even has a 10-year full warranty on the heat exchanger. A consumer magazine survey ranked Aqua Star first in tankless heaters. Easy to install — just mount on a wall, vent, and light.
