The 4-gallon point-of-use electric mini tank water heater delivers hot water instantly where you need it, with fast recovery and less standby loss. The adjustable thermostat allows a temperature range from 50°F to 149°F. Compact in size at 14.5" x 14.5" x 12.9", it can be wall- or floor-mounted under sinks or counters and simply plugs into a standard 120V outlet. Built for long-lasting performance, the 3-layer porcelain enamel glass-lined tank resists corrosion and leaks, while the extra-thick anode rod helps maintain heating efficiency. The stainless steel heating element offers four times the corrosion resistance of copper and delivers up to 99% heating efficiency for energy savings and extended lifespan. Safety is assured with UL listing and a T&P relief valve to protect against excess pressure and temperature.1 Year Manufacturer Warranty
