And while they cost more than electric-only models, installation is similar and payback time is short.Despite this expense, water heaters are typically ignored until they break, leaving you with no hot water and, possibly, a flooded basement.
New storage tank water heaters are required to operate more efficiently, and tankless (on-demand) water heaters are even more efficient than that. ![]() But if youre building a new home or adding to an existing one, installing a tankless water heater may make economic sense. We compared the results with those of conventional tanked heaters from Rheem, one gas and one electric, as well as with a Rheem electric heat pump water heater, which is a variation on a tanked water heater. The test used a high draw pattern equal to using 84 gallons of water per day. Thats the daily equivalent of taking several showers, running the dishwasher, washing one load of laundry, and turning the faucet on and off multiple times. Water Heater Reviews Plus Or MinusThe test used an inlet temperature of 58 F for gas models and 74 F for electrics (plus or minus 2 F) and a target outlet temperature of 120 F. Using the purchase price, annual energy cost, and an estimated cost of installation, we calculated the payback time for both new and replacement installations. Payback time was longer for a tankless unit that replaced an existing storage tank but more reasonable with new construction. The size you buy depends on the number of people living in your home and your peak water usage. ![]() But that doesnt mean that household needs a 100-gallon storage tank. For storage tank water heaters, its important to consider the first-hour rating, which is the number of gallons a water heater can deliver in an hour starting with a full tank. To calculate what FHR will work for your home, use the calculator on the Energy Saver website. As the result of recently updated efficiency standards, water heaters under 55 gallons now have a 4 percent boost in efficiency, while water heaters 55 gallons or more have efficiency gains of 25 to 50 percent depending on the technology usedheat pump or condensing. See water heater types below.) And dont assume a new water heater will fit where your old one was. Because of increased insulation and other efficiency improvements, some newer models may be wider andor taller than your old water heater. Thats the number that tells you how much hot water the heater can deliver over a set period of time. If you have a big family and multiple bathrooms, youll need a tankless water heater with a higher GPM. Some types are claimed to cut energy costs by up to half that of regular storage models. But their added up-front costs mean payback time might be longer. ![]() Theyre more energy-efficient than a storage tank but provide only a limited flow of hot water per minuteabout 3.5 gallons, depending on inlet water temperatures. They use about 60 percent less energy than standard electric water heaters.
