Heat pumps usually cost less to operate than electric resistance heating, but the difference depends on your climate, electricity rates, and how old your current system is
A heat pump moves heat from outside air (or ground) into your home instead of generating heat directly. Electric resistance heating—the kind in baseboard heaters, space heaters, and many furnaces—converts electricity directly into warmth. Because heat pumps move existing heat rather than create it, they use roughly one-third to one-half the electricity that resistance heating uses to reach the same indoor temperature. In most climates, that means lower monthly bills.
The real cost difference shows up over a full heating season. If you're comparing a heat pump to an old electric furnace or baseboard heaters you're running now, the heat pump will almost certainly cost less per month. If you're comparing a heat pump to a newer high-efficiency electric resistance system, the gap narrows—but the heat pump still usually wins in moderate climates.
Key Takeaways
- Heat pumps use one-third to one-half the electricity of electric resistance heating to deliver the same warmth, which translates to lower monthly heating bills in most climates.
- In very cold climates below 0°F, heat pumps lose efficiency and may need a backup resistance heater, which can erase some of the cost advantage on the coldest days.
- Your local electricity rate matters as much as the equipment: in areas with cheap electricity, the monthly savings shrink; in areas with expensive electricity, heat pumps save more.
- Installation costs for a heat pump are higher upfront than for electric resistance heating, so payback takes three to seven years depending on your climate and current system.
- If you're replacing an old electric furnace or baseboard system, a heat pump usually pays for itself through lower bills before the equipment needs replacement again.
How the operating costs actually compare
A heat pump's efficiency is measured in COP (coefficient of performance), which tells you how many units of heat you get for each unit of electricity used. A typical air-source heat pump has a COP of 2.5 to 3.5 in moderate weather, meaning it delivers 2.5 to 3.5 times as much heat energy as the electricity it consumes. Electric resistance heating has a COP of 1.0—every kilowatt-hour of electricity becomes one kilowatt-hour of heat, with no multiplication.
In dollars, this means if you heat a 2,000-square-foot home with electric baseboard heaters and spend $1,500 on heating in a winter, a heat pump in the same home and climate would cost roughly $500 to $750 for the same warmth. The exact savings depend on how cold your winters get and how many hours per day you need heat.
That advantage shrinks in very cold climates. When outdoor air drops below 0°F, most air-source heat pumps lose efficiency and switch to a backup electric resistance heater (called auxiliary heat or emergency heat). On those coldest days, you're partly running on resistance heating, so the COP drops. Ground-source heat pumps stay efficient in extreme cold because the ground stays warmer than the air, but they cost much more to install.
What your electricity rate means for the math
The monthly bill depends on both the equipment and the price you pay per kilowatt-hour. If your utility charges $0.10 per kilowatt-hour, the savings from a heat pump are meaningful but not dramatic. If you pay $0.18 or more per kilowatt-hour (common in the Northeast and California), the same heat pump saves you significantly more money each month.
You can find your rate on your most recent electric bill—look for a line that says "per kWh" or "rate" in the charges section. Multiply that rate by the difference in kilowatt-hours between the two systems to estimate your annual savings. If you're unsure how many kilowatt-hours your current heating uses, your utility can often provide a year of billing history.
Installation costs and payback time
A heat pump system costs $4,000 to $8,000 installed for a typical home, depending on whether you need ductwork and how complex the installation is. An electric furnace or baseboard heater system costs $2,000 to $4,000. That $2,000 to $4,000 difference is the extra upfront cost you're paying for lower monthly bills.
Payback time—how long until the monthly savings add up to cover that extra cost—usually falls between three and seven years. In a cold climate with high electricity rates, payback can happen in three to four years. In a mild climate with cheap electricity, it might take six or seven years. After payback, every month of lower bills is pure savings.
If you're replacing an old electric furnace or baseboard system that's failing, the payback clock starts when ready. You're not choosing between "keep the old system" and "buy a heat pump"—you're choosing between two replacement options. In that case, the heat pump almost always makes financial sense over the life of the equipment (15 to 20 years for a heat pump).
When a heat pump costs less than electric heating from day one
If your current system is electric resistance heating and it's costing you $150 or more per month in winter, a heat pump will lower that bill when ready. You'll see the savings on your first winter electric bill, even though you haven't yet recouped the installation cost. This is the most common scenario for homeowners switching from baseboard heaters or old electric furnaces.
You also save money faster if you're replacing a system that's already broken. You have to spend money on a new heating system regardless—the question is whether to spend $3,000 on a new electric furnace or $6,000 on a heat pump. The heat pump's lower monthly bills make up that $3,000 difference in a few years.
Climate matters more than you might think
In the Pacific Northwest, upper Midwest, and Northeast, where winters are long and cold, heat pumps save the most money because you run them for many months. In the South and Southwest, where heating is needed only a few weeks per year, the monthly savings are smaller—but so is the total heating bill, so the payback time is longer.
Very cold climates (Minnesota, Montana, upstate New York) present a special case. Air-source heat pumps still save money, but the auxiliary heat kicks in more often, which reduces the advantage. If you live where winter temperatures regularly drop below 0°F, ask a local HVAC contractor whether a ground-source heat pump or a cold-climate air-source heat pump makes sense for your home. Cold-climate models are designed to stay efficient in extreme cold.
Other costs that affect the total picture
Maintenance costs are similar between heat pumps and electric resistance systems—both need annual filter changes and occasional professional service. Heat pumps may need refrigerant checks or compressor repairs over their lifetime, but electric furnaces can need heating element replacement. Neither system is significantly cheaper to maintain than the other.
If you need to add ductwork to your home for a ducted heat pump, that adds $1,000 to $3,000 to installation. A ductless (mini-split) heat pump avoids that cost and can be cheaper to install, though it heats fewer rooms. If you're replacing an electric furnace that already has ducts, a ducted heat pump uses the existing ducts and costs less to install.
Frequently Asked Questions
Will a heat pump save money if I live somewhere that gets very cold?
Yes, but the savings are smaller than in moderate climates. In very cold weather, the heat pump's efficiency drops and it relies more on backup electric resistance heating. Even so, most homeowners in cold climates save 20 to 40 percent on heating bills compared to electric resistance heating. Cold-climate heat pumps are designed to stay efficient longer as temperatures drop.
What if I have natural gas heating now—should I switch to a heat pump?
That's a different comparison. Natural gas is usually cheaper than electricity per unit of energy, so a gas furnace often costs less to run than a heat pump. However, if your gas utility rates are high or you're in an area moving away from gas, a heat pump may make sense. Compare your current gas bill to a heat pump estimate from a local contractor.
Can I use a heat pump with my existing electric furnace?
Yes. A heat pump can be paired with your existing furnace as a backup, so the furnace runs only on the coldest days. This hybrid setup costs less to install than replacing the furnace entirely and still saves money on most winter days. Ask an HVAC contractor whether your current ductwork and electrical service can support this setup.
How much will my electric bill actually go down?
That depends on your current heating costs, local electricity rates, and climate. If you're spending $200 per month on electric baseboard heating, expect to spend $70 to $100 per month with a heat pump. If you're spending $100 per month, expect roughly $35 to $50. Your contractor can estimate savings based on your home's size and your local utility rates.
Is a heat pump worth it if I only heat my home a few months per year?
The payback takes longer in mild climates because you use less heating overall, so the monthly savings are smaller. However, heat pumps also cool efficiently in summer, so if you're comparing total heating and cooling costs, a heat pump often makes sense even in warm climates. The payback might stretch to seven or eight years instead of three to five.
