Trutankless’ Vero electric tankless water heaters measure 17.2 inches (H) by 23.8 inches (W) by 5.5 inches (D). They offer easy installation and 99 percent efficiency, require no venting, and eliminate scale buildup and maintenance. The patent-pending Velix technology heats water as it flows rapidly through the 24 linear feet of heating element. The sheer length combines with the unique horizontal orientation and ceramic thermal insulation to maximize output and prevent element failure. The horizontal design creates a self-flushing effect so efficiency is never compromised by mineral buildup, as with other water heaters.
