In virtually all cases, YES! The greatest savings will occur when replacing an oversized electric tank (80 gallons) in a home with minimal hot water demand.
Think about your typical hot water usage: 10 to 12 minutes in the shower, a few minutes with the bathroom lavatory, washing the dishes or running the dishwasher after dinner and the occasional load of laundry on ‘hot’ and you quickly see there isn’t a lot of hot water demand in a typical day. BUT – your hot water tank has to be ready – 24 hours a day – 7 days a week. All the energy spent on keeping the water in the tank hot is wasted energy. The Eemax heater only turns on when there is a hot water demand and instantaneously heats water to meet that demand… and no more. When there is no hot water demand, there is no hot water expense!
In addition, no hot water tank means never running out of hot water again! When properly sized, the Eemax Tankless hot water heater makes all the hot water you need on demand.
