Why all-electric home heating is having a moment
U.S. homes are shifting to all-electric heating because the numbers finally make sense. Modern air-source heat pumps can deliver three to four units of heat for every unit of electricity. That’s a giant leap over older electric heaters that only convert electricity into heat one-for-one. Add smarter controls, better cold-weather performance, and strong incentives, and electric has graduated from “backup” to primary heat for many homes. In this buying guide—your /buying-guide/allelectric-home-heating-options reference—I’ll explain what works, where it works, and how to choose. You’ll see cost ranges, efficiency standards (SEER2/HSPF2/COP), and simple steps to size and install the right setup. I’ll also point to product pages and real guides from The Furnace Outlet so you can compare options quickly. If you want a deeper browse, start with the HVAC Tips for plain-English explainers and updates.
The common concern: “Will electric heat keep me warm in real winter?”
Short answer: yes—if you pick the right system for your climate and size it correctly. Today’s cold-climate heat pumps are engineered to hold ~70% of their rated heat output at 5°F, and many continue operating down to −15°F or lower with smart controls. That matters in the Midwest and Northeast where winter design temps are tough. In mild and moderate regions, standard heat pumps shine with low bills year-round. For rare deep-freeze hours, you can add electric heat strips or a dual-fuel backup for peace of mind. Comfort isn’t just about raw heat; it’s steady temperature, good airflow, and quiet operation—areas where variable-speed compressors and smart thermostats excel. If you’re still unsure, compare models built for “cold-climate” performance and look for ENERGY STAR Most Efficient 2025 labels.

How electric systems hit 300 400% efficiency (and why resistance heat is ~100%)
A heat pump doesn’t create heat; it moves it. That physics trick is why you’ll see Coefficient of Performance (COP) values of 3–4 in typical conditions. In simple terms, 1 kWh in can deliver 3–4 kWh worth of heat into your home. Direct electric resistance systems (baseboards, older space heaters) convert nearly 100% of electricity into heat, but never multiply it. For cooling and heating comparisons, look for SEER2 (cooling) and HSPF2 (heating). In 2025, federal minimums use the newer SEER2 test, which better reflects real ducts and real homes. That’s why some newer SEER2 numbers look lower than older SEER labels—they’re more honest. If you want the longer version, the Furnace Outlet SEER2 guides explain how the test changed and what numbers to aim for when buying.
Air-source heat pumps: specs, costs, and best uses (most efficient overall)
For most homes, air-source heat pumps are the winning all-electric option. Aim for ENERGY STAR Most Efficient 2025 levels: roughly SEER2 ≥16, HSPF2 ≥8, and COP ≥1.75 at 5°F for cold-climate models. Typical installed costs are $10,000–$25,000, depending on size, brand, ducts, and controls. These systems provide both heating and cooling, integrate with smart thermostats, and work in all U.S. climate zones with the right configuration. In colder states, choose cold-climate units designed to maintain capacity at low outdoor temps; in milder regions, standard models are excellent.

Ductless mini-splits: zoning superpowers for older homes and additions
If your home doesn’t have ducts or you want room-by-room control, look at ductless mini-split heat pumps. Many offer SEER ratings in the 20–30+ range and whisper-quiet indoor units. Because each zone has its own thermostat, you only heat rooms you actually use, which cuts waste. Installed cost usually ranges $3,000–$12,000 depending on the number of zones (2–8 is common). Mini-splits shine in retrofits, finished basements, sunrooms, and home offices that never feel right with central air. Browse options: ductless mini-splits, DIY mini-splits,
Electric boilers: best choice for radiant floors and radiator homes
Electric boilers are a strong fit where hydronic systems already exist—think radiators or radiant floor heating. They deliver 95–99% point-of-use efficiency, pair with existing piping, and offer smooth, even heat. Expect $8,000–$18,000 installed when you include pumps, expansion tanks, and smart controls. The big win is zoning: you can heat bedrooms cooler and keep common areas warmer. In very cold climates, a heat-pump-plus-boiler approach can work well: the heat pump covers most hours efficiently, and the boiler handles the rare extreme nights. If you’re modernizing the rest of the system, don’t forget indoor air quality: MERV 11–13 filters in any forced-air sections maintain airflow while catching fine dust.

Smart electric radiators: simple installs and precise room control
If you need targeted heat without touching ducts or pipes, smart electric radiators are practical. They convert electricity to heat at nearly 100% efficiency and typically cost $200–$800 per room plus a standard 120/240V outlet. Use them for retrofits, rentals, bonus rooms, or home offices where central upgrades are hard. The “smart” part matters: app scheduling, open-window detection, setback temps, and child-lock keep comfort steady and bills in check. They also play nicely with time-of-use electric plans—pre-warm rooms when power is cheaper, then coast. If your long-term plan is a whole-home heat pump, radiators can still stick around for rare cold snaps or guest rooms you heat only on demand.

Sizing & installation: simple rules, then verify with Manual J
Start with this quick rule of thumb: about 500 sq ft per ton of heat-pump capacity. Examples: 1,500 sq ft → ~3 tons, 2,000 sq ft → ~4 tons, 2,500 sq ft → ~5 tons. Now verify with a Manual J calculation to account for insulation, windows, air-sealing, ceiling height, and your local climate. Before install, handle the essentials:
-
Electrical panel: confirm 240V circuits; plan upgrades ($3,200–$5,200) if needed.
-
Permits & code: line-set routing, clearances, disconnects.
-
Insulation & air-sealing: lower the load first; equipment can be smaller.
-
Contractor selection: get multiple quotes; ask for heat-pump experience.
-
Smart thermostat setup: schedules, sensor placement, and lockouts.

Costs, incentives, and future-proofing for 2025 and beyond
Among electric options, heat pumps usually have the lowest operating cost, often saving 25–75% versus resistance heat. You can push bills even lower by using time-of-use rates, smart schedules, and proper sizing to avoid short-cycling. Many homeowners offset 20–50% of installed cost with federal tax credits, utility rebates, and local programs. For financing, check HVAC Financing
