Do I really save money with a tankless heater?
Tankless heaters use less energy than traditional tank style heaters. Traditional tank type heaters sit with 40 or 50 gallons of hot water in them all day, this is known as stand-by loss. They are wasting energy keeping this water hot until someone needs it. Tankless water heaters produce hot water only when it is needed. By using less energy tankless heaters will save you a significant amount of money in the long run.
