STIEBEL ELTRON---3*---------NA-------NA

The ACCELERA 300 features an 80 gallon storage capacity and a unique wrap-around aluminum condenser which isolates the refrigerant piping from the potable water. The unit will provide fifty gallons of potable water before the backup electric element kicks in to handle the larger needs. The unit has a sacrificial anode system which will require periodic replacement but the water heater is backed by a very good warranty. stiebel-eltron-usa.com
