Before installing a gas water heater, consider a heat pump water heater. Heat pump water heaters are more efficient than gas water heaters because they move heat rather than making it. They pull heat from the surrounding air and transfer it—at a higher temperature—into the tank to heat your water. Because they use warm ambient air temperature to do most of the work, they’re very efficient.

Compared to oil, propane, or electric water heating systems, heat pump water heaters are the lowest cost fuel source. They might cost more upfront for installation and increase your household electricity bill, but you’re likely to save money in the long run because they don’t use expensive fossil fuels to run. Plus, Energize Connecticut offers cash incentives and low-interest subsidized financing to help pay for installing a heat pump water heater.

Heat pump water heaters also significantly reduce a big cost that is an increasing concern in Connecticut: the escalating cost of climate change. Learn more about the benefits of heat pump water heaters and use the Clean Heating & Cooling Calculator on our Clean Heating and Cooling page to see what a heat pump water heater would mean for your home’s budget—and how much it would reduce your carbon emissions.

Additional Details

You don't use hot water 24 hours a day. Yet a standard tank-type water heater consumes energy around the clock to keep the water in its tank hot.

ENERGY STAR-certified natural gas tankless water heaters give you hot water when you need it, without an energy-consuming storage tank. Using a tankless water heater can trim your water heating costs up to 30 percent. You’ll also enjoy these benefits:

  • Continuous hot water – Tankless water heaters provide a continuous flow of hot water, on demand. That means you don’t have to suffer through a cold shower if you're the last one in line. Unlike a conventional tank-type water heater, hot water is always there when you need it.
  • Space-saving design – A qualified tankless model saves you an extra closet's worth of space compared to a tank-type water heater. Gas tankless water heaters are small and wall-mounted, unlike bulky tank-type water heaters.
  • Fewer worries – Tankless water heaters typically last 20 years, much longer than any conventional tank-type water heater. And because it’s tankless, you don’t have to worry about tank leaks and water damage.

Going tankless is more affordable with an instant discount up to $300. It’s available if you install an ENERGY STAR-certified tankless natural gas water heater with electric ignition. Whether you’re replacing an old water heater or installing one in a new home, you'll save money up front.

ENERGY STAR is a widely recognized and trusted label on products that meet strict energy efficiency requirements set by the U.S. Environmental Protection Agency and the U.S. Department of Energy. By using less energy, these products also help reduce greenhouse gas emissions that contribute to climate change. Learn more at the ENERGY STAR website.

Go tankless today and enjoy hot water and savings you can count on.
