If your home heats with electric baseboard, wall heaters, or an electric furnace, you already pay full retail electricity for every unit of heat. That is the reason electric-heated homes tend to have the strongest heat pump payback story of any fuel-switch case.
Electric resistance heat cannot get more efficient. A heat pump can, because it moves existing heat from outdoor air instead of manufacturing it from raw electricity.
Quick answer
Electric-resistance heating, including baseboard, wall convectors, and electric furnaces, turns electricity into heat at close to a 1-to-1 ratio: 1 kWh in, about 1 kWh of heat out. A heat pump instead uses electricity to move heat, so it can deliver more heat energy than the electrical energy it consumes. The Department of Energy states that modern air-source heat pumps can cut electricity use for heating by about 50 percent compared with furnaces and electric baseboard heaters, and ENERGY STAR describes an efficient heat pump as capable of delivering up to three times more heat energy than the electricity it uses. That gap is why electric-heated homes are a priority replacement case for state programs, not just a marketing claim.
Why the efficiency gap exists
The measure that matters is coefficient of performance, or COP. Electric-resistance heat has a COP of about 1: every watt of electricity becomes one watt of heat, and it cannot go higher. A heat pump's COP is typically 2 to 4 depending on the model and the outdoor temperature, because it is transferring heat rather than creating it.
That COP is not fixed. It falls as the outdoor temperature drops, which is why the honest comparison always includes a design-temperature number, not just the rated efficiency measured at a mild 47°F. The mechanics of that drop-off, and what separates a standard heat pump from a cold-climate model at low temperatures, are covered in heat pump efficiency by outdoor temperature and cold-climate heat pumps.
Heat pump vs electric baseboard at a glance
| Factor | Electric baseboard / resistance heat | Heat pump |
|---|
| How it makes heat | Converts electricity directly to heat, COP ≈ 1 | Moves heat from outdoor air, COP typically 2 to 4 |
| Electricity use for the same heat | Baseline | Roughly 50 percent lower per DOE, more at mild temperatures |
| Cooling | Not provided | Most systems also cool |
| Distribution | Zone-by-zone, no ducts needed | Ductless heads, ducted air handler, or a mix |
| Cold-weather output | Constant, unaffected by outdoor temperature | Drops with temperature; cold-climate models hold output better |
| Upfront cost | Low equipment cost, simple wiring | Higher equipment and install cost, may need electrical work |
| State rebate treatment | Not eligible for heat pump rebates | Often the strongest rebate tier, since it displaces resistance heat |
The rebate angle is real, not just marketing
Several state programs give electric-resistance replacement its own eligibility lane, because the efficiency gain is the largest and easiest to verify. Mass Save's air-source heat pump rebates apply to systems that displace oil, propane, or electric-resistance heat, with whole-home and partial-home tiers plus an income-based enhanced incentive. Efficiency Maine runs a similar per-unit rebate structure with higher tiers for moderate- and low-income households. Neither program guarantees a specific dollar figure for your project, since amounts depend on system size, income tier, and utility territory. Puget Sound Energy runs a similar lane in Washington: its largest single rebate tier, up to $4,000 for income-qualified customers, is specifically for converting electric-resistance heat to a heat pump. See Massachusetts heat pump cost and rebates, Maine heat pump rebates, and Washington heat pump rebates for the current tiers, and confirm the numbers against the primary source before a contractor subtracts them from your quote.

What changes about the installation
Baseboard heat has no ducts, so a straight swap almost always means a ductless mini-split system, one or more ducted air handlers, or a mixed design. That is a different project than replacing a furnace. Compare the tradeoffs in ducted vs mini-split heat pump, and expect the quote to show a plan for every room the baseboard used to heat, not just a single outdoor unit and a promise.
Electric-resistance heat is also usually on simple dedicated circuits, which does not automatically mean the panel has room for heat pump circuits, disconnects, and any retained backup heat. Ask the contractor to document panel capacity and new circuits rather than leaving electrical work as a placeholder. That scope line is explained in the heat pump electrical panel upgrade guide.
For overall project cost context, most ducted or ductless heat pump projects land between $8,000 and $25,000 before rebates, with the details broken down in the real cost of a heat pump. Where your project lands in that range depends on square footage, number of zones, and how much electrical work is required.
Quote red flags specific to this scenario
- The quote treats "replacing baseboard" as a single outdoor unit with no room-by-room head or duct plan.
- Panel and circuit work is not shown, even though baseboard wiring is not the same as a heat pump's electrical needs.
- The proposal keeps zero backup heat with no design-temperature justification, in a cold-climate state.
- A rebate is subtracted from the price with no program name, tier, or income requirement shown.
- The contractor cannot state the system's rated capacity and COP at your local winter design temperature, only the 47°F rating.
Frequently Asked Questions
Is electric baseboard heat actually more expensive to run than a heat pump?
For the same amount of delivered heat, yes, in almost all cases. Baseboard heat has a fixed COP of about 1, while a heat pump moves more heat than the electricity it consumes, so it uses meaningfully less electricity for the same comfort. The size of the gap depends on climate, equipment, and how well the new system is sized.
Do I need to remove all the baseboard heaters?
Not necessarily. Some homeowners keep a portion of baseboard as a backup or for a room the heat pump design does not cover well. The quote should say which rooms the heat pump covers and what, if anything, stays as backup.
Will a heat pump still work when it's very cold outside?
Standard heat pumps lose capacity and efficiency as it gets colder. Cold-climate models are built to hold more of their output at low temperatures. Either way, ask for the capacity and COP at your design temperature, not just the mild-weather rating.
Are electric-resistance conversions eligible for the same rebates as gas or oil conversions?
Often the eligibility is similar or better, since displacing resistance heat is one of the clearest efficiency gains a program can fund. The exact rebate tier still depends on income, whole-home versus partial scope, and the utility territory, so confirm current numbers on the state program's own page before treating them as fixed.
Does removing baseboard heat affect my home's cooling?
Baseboard heat does not provide cooling. A heat pump typically adds cooling capability as part of the same system, which is a meaningful upside beyond the heating efficiency gain.
