Arkansas electricity is 25% below the national average. Here's what that means for heat pump operating costs.

Running cost in Arkansas

At Arkansas's 13.6¢/kWh electricity rate, the most efficient heat pump water heater saves an estimated $497 per year compared to a standard electric tank.

Inlet water temperature (62°F annual average) is close to the DOE test standard (58°F). Rated UEF values are a reasonable approximation of real-world performance.

Heat pump vs gas tank in Arkansas

At Arkansas prices (13.6¢/kWh electricity, $2.18/therm gas), a heat pump costs about $261 less per year to run than a standard gas tank, on the same DOE rated hot water load. See replacing a gas water heater in 2026 and all 50 states compared.

Both use the DOE medium draw test load (55 gallons a day). Gas price: EIA, 12-month avg. through Aug 2026. Replacing gas with a heat pump also means adding a 240V circuit (or choosing a 120V model) and a condensate drain, and the federal HEAR rebate no longer covers gas replacements.

Why Arkansas changes the call

01Energy cost

Arkansas electricity is 25% below the national average. That directly affects how much a heat pump saves compared to a standard electric tank.

02Climate impact

Incoming water averages 62°F annually and drops to about 50°F in winter. Colder water means the heat pump works harder and real efficiency is slightly lower than rated.

03Available incentives

State and utility rebates can significantly change the payback period. Check what's currently available before finalizing your decision.

Install requirements in Arkansas

Electrical

Dedicated 240V, 30A circuit (most models). Some newer 120V plug-in models exist but most residential units require 240V. Check the unit's nameplate for exact requirements.

Condensate drain

Heat pump water heaters produce condensate during operation. A condensate drain line to an approved location (floor drain, condensate pump, or exterior) is required.

Air space

Approximately 700 cubic feet of surrounding air (roughly a 10x10x7-foot room). The heat pump extracts heat from surrounding air. Insufficient air volume reduces efficiency and can cause the unit to underperform. Some manufacturers allow ducting to supplement air supply in smaller spaces.

Noise

Heat pump water heaters produce operational noise similar to a window AC unit (45-55 dB). Consider placement away from bedrooms.
