The amount you save will be determined by how much water you heat, the type of tankless water heater you select, and the efficiency of the water heater you replace. In general, depending on the efficiency of the equipment and the size and usage of your family, a tankless heater can save hundreds of dollars over the unit's lifetime compared to a standard tank.
Continuous Supply of Hot Water
Tankless units allow you to enjoy an endless hot water supply at a pre-set temperature level. They can produce as much as 5 to 7 gallons of hot water per minute. This means you can run multiple showers and appliances simultaneously without running out of hot water.
Greater Life Expectancy
Tankless water heaters have a far greater life expectancy than traditional water heaters. If properly installed and maintained, your tankless model can last up to 20 years – twice the lifetime of a conventional water heater.
