Do tankless water heaters use a lot of electricity? That depends; if you are comparing it with a tank water heater, then it doesn’t use more electricity and is 24-34% more efficient than a tank water heater if both unit’s daily use is less than 41 gallons of water.
Tankless heaters can be 24-34% more energy-efficient than regular water heaters for households that use 41 gallons or fewer of hot water daily. Tankless heaters can be 8-14% more energy-efficient for households that use around 86 gallons daily.
Some units may need electricity for the power exhaust vent to function properly as venting is crucial for indoor tankless water heaters. Although electricity consumption is higher, it is still lower than in the case of electric-powered counterparts. When heating water, gas models require no more than a few amps at 120V.
For homes that use 41 gallons or less of hot water daily, demand water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters. They can be 8%–14% more energy efficient for homes that use a lot of hot water -- around 86 gallons per day.
Energy.gov summarizes the potential tankless water heater energy savings this way: Tankless heaters can be 24-34% more energy-efficient than regular water heaters for households that use 41 gallons or fewer of hot water daily. Tankless heaters can be 8-14% more energy-efficient for households that use around 86 gallons daily.
Generally speaking, these units will consume less energy than a traditional hot water heater, although how much electricity tankless water heaters use will still depend on the demand you create in your home. Since they don't need to heat water when you aren't using them, tankless heaters may only run for two hours a day or so.
Tankless water heaters are more energy efficient for your homes because it is not constantly running to maintain hot water. According to energy research done by Energy.gov, if you are using a 40-gallon tank of hot water or less, your energy demand is typically less than 50 percent with a tankless water heater compared to a water heater tank.
Sure, gas tankless heaters have a few cons, but overall switching to this type of heater is a good option if you want a single whole house unit. Gas heaters are simply more powerful than electric heaters and they can supply a large home in a cold climate with plenty of hot water.
