Comparisons
Only pairs where the two appliances differ in mechanism, duty cycle or efficiency — where there is a real verdict rather than two rows of a table. 20 comparisons.
- Is an electric fireplace cheaper to run than a space heater?
They cost exactly the same to run at the same setting. Both are 1,500 W resistance heaters; only the cabinet differs.
Electric fireplace $301/yr · Space heater $803/yr
- Is an electric blanket cheaper than a space heater?
Dramatically cheaper, because it heats a person rather than a room.
Electric blanket $26.78/yr · Space heater $803/yr
- Is baseboard heating cheaper than a space heater?
Per watt they are identical. Baseboard usually costs more in practice because it is sized to heat the whole room and runs on a wall thermostat.
Electric baseboard heater $703/yr · Space heater $803/yr
- Is a heat pump cheaper to run than an electric furnace?
Far cheaper — typically two to four times — because a heat pump moves heat instead of creating it.
Electric furnace $3,012/yr · Heat pump $1,171/yr
- Is a heat pump cheaper than baseboard heating?
Yes, by a wide margin, for the same reason it beats a furnace — it moves heat rather than generating it.
Electric baseboard heater $703/yr · Heat pump $1,171/yr
- Is a mini-split cheaper to run than baseboard heating?
Yes. A mini-split is a heat pump, so it delivers several units of heat per unit of electricity while baseboard delivers one.
Electric baseboard heater $703/yr · Ductless mini-split $361/yr
- Is a window air conditioner cheaper to run than a portable?
Yes, and by more than the wattage suggests, because a single-hose portable fights its own exhaust.
Portable air conditioner $412/yr · Window air conditioner $337/yr
- Is a window unit cheaper than central air conditioning?
For one room, yes, easily. For a whole house, central air is usually cheaper than running a window unit in every room.
Central air conditioner $1,125/yr · Window air conditioner $337/yr
- Is a ceiling fan cheaper than air conditioning?
Far cheaper — but it does a different job. A fan cools people, not rooms.
Ceiling fan $32.13/yr · Window air conditioner $337/yr
- Is a dehumidifier cheaper than air conditioning for a damp room?
Yes for humidity alone, but it adds heat to the room, so in summer it can raise your cooling bill.
Central air conditioner $1,125/yr · Dehumidifier $241/yr
- Is an air fryer cheaper to run than an oven?
For one or two portions, yes — usually by more than half — despite drawing similar wattage.
Air fryer $35.14/yr · Electric oven $80.33/yr
- Is a toaster oven cheaper than a full oven?
For small dishes, yes — typically a third to a half the cost — because it heats far less empty space.
Electric oven $80.33/yr · Toaster oven $32.80/yr
- Is a microwave cheaper than an oven?
Much cheaper for reheating — often by a factor of ten — because it heats the food directly instead of the air around it.
Electric oven $80.33/yr · Microwave $20.08/yr
- Is a slow cooker cheaper than an oven?
It depends on the dish. A slow cooker wins on a long braise, but an oven run for one hour uses less than a slow cooker left on for eight.
Electric oven $80.33/yr · Slow cooker $134/yr
- Is induction cheaper to run than an electric stove?
Yes, by roughly 15–20% for the same cooking, because far less heat is wasted heating the cooktop and the room.
Electric stove $66.94/yr · Induction cooktop $54.22/yr
- Is an electric kettle cheaper than boiling water on the stove?
Yes. A kettle is a sealed, insulated vessel with the element in the water, so almost nothing is wasted.
Electric kettle $15.06/yr · Electric stove $66.94/yr
- Is a laptop cheaper to run than a desktop?
Yes, typically by three to five times, because every component in a laptop was designed to run from a battery.
Desktop computer $80.33/yr · Laptop $26.78/yr
- Is a games console cheaper to run than a gaming PC?
Yes, roughly by half, because a console is a fixed design tuned for one power budget.
Game console $36.15/yr · Gaming PC $107/yr
- Is a robot vacuum cheaper to run than an upright?
Per session yes, but over a month they land in the same range, because the robot runs far longer.
Robot vacuum $4.02/yr · Vacuum cleaner $15.06/yr
- Does a chest freezer cost more to run than a refrigerator?
No — usually less, despite being colder, because a chest design loses far less cold air when opened.
Chest freezer $48.20/yr · Refrigerator $84.35/yr
