Every plug-in electric heater turns power into heat at the same rate, so the efficiency game is really about matching the heater type to the room and refusing to heat the hallway. The picks below are the owner-proven face of each type, with the running-cost truth up front.
1. Best All-Night: DeLonghi 2400W Oil Column
The oil column is the bedroom classic because it's silent and its thermostat cycles gently all night, and DeLonghi's carries 4.5 stars across 263 reviews. The timer means warm-at-wake without paying for warm-at-2am.
Around $140, slow to warm a cold room, which is the type's nature: columns hold heat rather than blast it.
What We Like:
- Silent operation
- Cycling thermostat
- 24-hour timer
What We Don't Like:
- Slow initial warm-up
2. Best Fast Heat: DeLonghi 2200W Ceramic
The ceramic tower is the opposite temperament: heat on your shins in thirty seconds, an eco mode that throttles once the room arrives, and 4.6 stars from 246 owners. It suits studies and lounges used in bursts.
Around $120, with the fan hum that all ceramic heaters carry on high.
What We Like:
- Heat in seconds
- Eco throttle mode
- Tip-over cutoff
What We Don't Like:
- Fan hum on high
3. Best Panel: Noirot 2000W Spot Plus
The French-made Noirot is the panel heater tradies install in bedrooms across the cold states: silent, wall-mountable, with a thermostat accurate enough to hold a nursery steady. Its 159 owners average 4.6, and the ten-year warranty says the rest.
At around $270 it's the buy-once electric heater, and it still obeys the arithmetic below.
What We Like:
- Precise silent thermostat
- Wall-mount option
- Ten-year warranty
What We Don't Like:
- Panel-class price
The running-cost truth
Every electric heater costs the same per kilowatt. A 2400W heater flat-out costs roughly 80 cents an hour at typical rates, whatever its marketing. The savings live in thermostats, timers, zoning and door seals, not in magic elements.
Reverse-cycle air conditioning is the real efficiency story. A heat pump moves three-plus units of heat per unit of power, which is why a split system heats for a third of the cost of any plug-in. Where one exists, it should win; these heaters are for the rooms without one.
Heat the person before the room. An electric throw on the couch costs cents a night. The cheapest kilowatt is the one never drawn, which is the least glamorous and most honest line on this page.

FAQs
Which heater type is cheapest to run?
At the same thermostat setting, they cost the same per hour of element time; types differ in how well they hold a set temperature. Columns and panels cycle efficiently overnight; fan heaters win short bursts.
Are the no-name heaters on marketplaces safe?
Certification is the issue, not efficiency. The brands above carry Australian electrical approval and cut-offs; a $25 mystery fan heater is the wrong place to save.
