Heat pumps and electric space heaters both use electricity — but heat pumps are fundamentally different. A heat pump moves heat from outside air into your home, delivering roughly two to three times more heat per kilowatt-hour than a standard electric heater, with the multiple falling as the outdoor temperature drops. This comparison covers upfront cost, running cost, efficiency, and real-world performance so you can decide which makes sense for your home.
A heat pump moves two to three times more heat than the electricity it consumes; a resistance heater converts one-for-one and cannot do better. For the same delivered heat that works out to about 50–69% less on the bill, the low end in a cold winter and the high end in a mild one.
Electric space heaters cost $25–$150 upfront. Heat pumps start at $3,000–$5,000 installed. If you need heat for one room or one season, an electric heater is the obvious budget choice.
Heat pumps are designed as whole-home or whole-zone systems. A 1,500W space heater delivers only 5,118 BTU/hr — enough for roughly 150 sq ft — and a wall outlet will not give you more. For heating an entire house, a heat pump is the only practical electric option.
| Feature | Heat Pump | Electric Heater |
|---|---|---|
| Heating Method | Moves heat from outside air into home | Converts electricity directly into heat |
| Efficiency (COP) | Seasonal 2.0–3.2 (200–320%), falls as it gets colder | Exactly 1.0 (100%), whatever the heater type |
| Warm-Up Speed | Slow — 15–30 min for whole home | Fast — 2–3 minutes for one room |
| Upfront Cost | $3,000–$8,000 installed | $25–$150 |
| Cost per Million BTU Delivered | ~$19.30 at seasonal COP 2.8 | ~$54.04 — no heater type beats this |
| Cost to Run (winter) | ~$182–$292/month (whole home, 2,000 sq ft) | ~$66/month per 1,500W heater (8 hrs/day) |
| Room Coverage | Whole home or multi-zone (1,000–3,000+ sq ft) | ~150 sq ft per 1,500W unit at 10 W/sq ft |
| Heat Output | Sized to the house — 24,000–60,000 BTU/hr typical | 1,500W is 5,118 BTU/hr, the outlet limit |
| Noise Level | Moderate — outdoor unit 50–60 dB | Silent (oil, panel) to 40–55 dB (fan models) |
| Installation | Professional required (1–2 days) | Plug into wall outlet |
| Best For | Whole-home heating, long-term savings, primary heat | Supplemental heat, one room, temporary use |
This is the one comparison where the heat pump wins outright, because both machines run on the same fuel. A heat pump moves heat rather than making it, so it delivers two to three times more heat than the electricity it consumes. An electric heater — ceramic, oil-filled, infrared, convection, baseboard — converts electricity to heat one-for-one. For the same warmth in the same room, the heat pump costs about 50–69% less, the low end in a cold winter and the high end in a mild one.
| Time Period | Heat Pump | Electric Heater | Note |
|---|---|---|---|
| Per Hour | $0.09–$0.14 | $0.28 | Same 5,118 BTU/hr delivered |
| Per Day (8 hrs) | $0.69–$1.11 | $2.21 | Heat pump range = seasonal COP 3.2 to 2.0 |
| Per Month (one room) | $21–$33 | $66 | 8 hrs/day for 30 days |
| Per Month (whole home) | $208 | $584 | 10.8 MMBtu load, 2,000 sq ft at 35°F |
A well-built standard ductless mini-split, and genuinely quiet at 19 dB. Note that the GL series is not a Hyper-Heating (H2i) unit — H2i is Mitsubishi's FH and FS series. If you need rated output far below freezing, buy an H2i model rather than this one.

View on Amazon →Premium variable-speed heat pump with the highest efficiency rating available. Smart thermostat integration, humidity control, and ultra-quiet operation. Requires professional installation.
View on Amazon →The most popular electric space heater in the US. Compact 1,500W design with built-in thermostat, overheat protection, and quiet operation. Great value for quick spot heating.
View on Amazon →Three heat settings, 24-hour timer and a precise thermostat, with no fan at all — the quietest way to heat a bedroom. The oil holds heat after shutoff, which smooths the temperature swing but does not reduce the energy used. At 1,500W it suits roughly 150 sq ft on the 10 W/sq ft rule.
View on Amazon →Wall-mount infrared panel heater with WiFi control and voice assistant support, safe-touch exterior, no floor space needed. Heat Storm advertises 750 sq ft; at 1,500W the 10 W/sq ft sizing rule puts it nearer 150 sq ft of real coverage.
