Water Heating

According to the Department of Energy, 15 to 25 percent of home energy costs come from water heating. There are more than 400 models of propane tankless and storage tank Energy Star water heaters. Propane water heaters cost up to 50 percent less to operate and can save up to one ton of greenhouse gas emissions each year compared with standard electric storage tank water heaters. And, as more efficient water heater technology becomes the new norm, it's a better time than ever for homeowners to consider what kind of water heater is best for their home.

In 2015, the Department of Energy raised the bar for water heaters. As the new National Appliance Energy Conservation Act regulations go into effect, new water heaters will be required to meet a higher efficiency rating. Watch the video below to learn what this change means for homeowners.


  • Tankless Water Heaters

    Tankless water heaters heat water only when it is being used, giving homeowners an endless supply of hot water — about 222 gallons/hour. There is no standby heat loss from storing heated water in a tank-type water heater. Propane-powered tankless water heaters can typically achieve a hot water flow rate that is three times that of the flow rate from electric storage or heat pump water heaters. The compact nature of tankless water heaters saves roughly 12 square feet of floor space compared with many electric systems. Propane tankless water heaters offer 50-60 percent lower CO2 emissions compared with electric storage tank systems, and up to 50 percent lower CO2emissions compared with heating oil storage tank systems in the Northeast.

  • Storage Tank Water Heaters

    Propane storage water heaters are a versatile, efficient, and reliable hot water solution for homeowners. In a tank water heater, a propane burner keeps the stored water at a constant temperature until the hot water is needed. Modern tank-type water heaters come in a variety of sizes and high efficiency models offer a variety of venting options. A propane storage water heater delivers the same amount of hot water as an electric tank, which is much larger and takes up more space in the home. An Energy Star-qualified propane unit will save between 13 and 16 percent in annual energy costs compared with standard electric and heating oil water heaters, respectively. Energy Star propane storage water heaters have CO2 emissions reductions of 1,900 pounds per year compared with a standard electric storage tank system, and there is a 35 percent reduction in CO2 emissions compared with heating oil storage tank systems in the Northeast.
