Review · Ceramic tower
A rare heater whose maker's coverage claim survives the math. The catch is on the safety sheet, not the spec sheet.

The Lasko 755320 is a 23-inch oscillating ceramic tower rated 900 W to 1,500 W, with two heat settings, a digital thermostat, an 8-hour timer, a remote, a cool-touch housing and automatic overheat protection. It is ETL listed and carries a 3-year warranty. Lasko publishes no tip-over switch and no child lock.
Most coverage claims on space heater boxes are marketing. A 1,500 W heater advertised for a "large room" or 300 square feet is quoting an assumption it does not state, and every roundup on this site computes its own figure precisely because the published ones so rarely hold up.
Lasko publishes 150 square feet for the 755320. Our sizing rule — 10 watts per square foot, average insulation, an 8-foot ceiling — puts a 1,500 W heater at exactly 150 square feet. The manufacturer's claim and the arithmetic land on the same number. That happens rarely enough on this site that it is worth leading with: it tells you Lasko sized this claim honestly rather than generously.
| Room size | Watts needed | BTU/h | Plug-in heaters |
|---|---|---|---|
| 100 sq ft | 1,000 W | 3,412 | 1 |
| 150 sq ft | 1,500 W | 5,118 | 1 |
| 200 sq ft | 2,000 W | 6,824 | 2 (different circuits) |
Computed as square feet x 10 W x insulation factor x (ceiling / 8 ft), for an average heated room — 10 W/sq ft, 8 ft ceiling. Heater count assumes the 1,500 W plug-in ceiling.

Who it is for
A home office, family room or bedroom at or under 150 sq ft where you want a real thermostat and a timer without paying for a metal cabinet.
What it is not for
A nursery, or a room where a curious pet or toddler can reach it. No child lock and no published tip-over switch is the wrong combination at floor height.
Lasko publishes an energy output range of 900 W to 1,500 W across two heat settings. That low figure matters more than it looks, for two separate reasons.
The circuit. At 1,500 W this heater draws 12.5 A, which is more than the 12 A continuous allowance of a standard 15 A circuit on its own. At 900 W it draws 7.5 A — comfortably inside the limit, with headroom left for a lamp, a laptop and a monitor. If the heater lives in a home office or a bedroom on a shared circuit, the low setting is the difference between a working evening and a tripped breaker. Why the breaker trips, in order of likelihood.
| Heater | Draw at 120 V | 15 A circuit (12 A limit) | 20 A circuit (16 A limit) |
|---|---|---|---|
| 900 W | 7.5 A | Fits | Fits |
| 1,500 W | 12.5 A | Over the limit | Fits |
| Maximum continuous | — | 12 A = 1,440 W | 16 A = 1,920 W |
Draw computed as watts / 120 V. The continuous limit is 80% of the breaker rating, which follows from the NEC's requirement to size a circuit at 125% of a continuous load (NFPA 70, 210.19(A)(1) and 210.20(A)).
The bill. Every electric heater costs the same per watt, so the low setting is 40% cheaper to run in exactly the proportion you would expect. Because Lasko publishes the 900 W figure, that saving can be computed rather than guessed at — which is not true of the many heaters that publish "low" and "high" with no numbers attached.
| Wattage | Per hour | 1 h | 8 h |
|---|---|---|---|
| 900 W | 16.5¢ | $0.17 | $1.32 |
| 1,500 W | 27.5¢ | $0.28 | $2.20 |
Computed at 18.34¢/kWh — the U.S. residential average for June 2026 (EIA, Electric Power Monthly, Table 5.6.A, released August 26, 2026). Your rate is on your own bill; substitute it and the arithmetic still holds. Figures assume full output for the whole period.
Run eight hours a day for a month, that is roughly $40 on the low setting against $66 on high at the U.S. average rate. The thermostat and the timer are what decide how much of that the heater actually spends — see below.
The rate behind every figure on this site
18.34¢per kilowatt-hour
U.S. residential average for June 2026. EIA, Electric Power Monthly, Table 5.6.A, released August 26, 2026.
This is the most recent month EIA has published. Residential rates move seasonally and vary enormously by state — from roughly a dime per kilowatt-hour in parts of the South to more than 40¢ in Hawaii — so treat it as a national reference point, not as your rate.
At this price the category norm is a mechanical dial marked from cold to hot. The 755320 publishes an adjustable thermostat with a digital display, an 8-hour timer, oscillation, and a remote that adjusts both the oscillation and the thermostat. Lasko also states the remote has onboard storage on the unit.
The thermostat and timer are the two features on any space heater that genuinely lower a bill, because running hours are the only variable there is. A heater that cycles off when the room reaches temperature and shuts down after eight hours spends measurably less than one left on high until someone remembers it. The full argument for thermostats and timers.
Lasko publishes three safety-related items for the 755320: a cool-touch housing, automatic overheat protection, and an ETL listing. Those are real and worth having. The ETL mark means the unit was tested to the applicable safety standard by a nationally recognized lab — what that does and does not certify.
What Lasko's page does not mention is a tip-over switch or a child lock. We are not going to infer either from a photograph or assume one exists because the heater is listed. On most heaters those absences would be minor. On this one they are the most important thing on the page, because of its shape.
The 755320 is 23 inches tall, 7 inches wide and 7.25 inches deep, and weighs 7.29 pounds. A tall, narrow, light object is a tipping profile. A dog leaning on it, a toddler pulling up on it, or a vacuum cord catching its base are all realistic ways for it to go over — and a tip-over switch is precisely the feature that decides what happens next. How the four tip-over mechanisms differ.

Published specifications from Lasko. The 5586 is included because it is the tower this one most often gets compared with; it is no longer sold as a single unit.
The comparison makes the trade plain. The 755320 has the better controls — a digital thermostat, a timer and a remote — and the tabletop 754201 has the safety feature it lacks. If the heater will stand where it could be knocked over, the smaller unit with a published tip-over switch is the more defensible choice; if it will stand in a clear corner of a home office and the thermostat and timer matter most, the 755320 is the better heater. Our full review of the Lasko 5586 covers the tower it replaced.
A home office, study or adult bedroom of around 150 square feet with average insulation, where the heater can stand in clear floor space away from foot traffic, animals and children. It suits someone who wants to set a temperature and a shut-off time and stop thinking about it, and whose circuit needs the 900 W setting to stay out of trouble.
It is the wrong choice for a nursery, a room with a dog that leans on furniture, or anywhere the heater might be knocked over — not because anything is known to be wrong with it, but because the one feature that matters most in those rooms is the one Lasko has not published.
And what we did not do: we have not tested these units, owned them, measured them or run them in a room. Everything above is compiled from published manufacturer specifications and live retail listings, with the electrical load, room coverage and running cost computed by us from the published wattage. The full method.
Lasko publishes 150 square feet, and our own sizing rule of 10 watts per square foot puts a 1,500 W heater at exactly 150 square feet for an average-insulation room with an 8-foot ceiling. In a drafty room expect closer to 120 square feet, and around 100 in an unheated space.
Lasko publishes an energy output of 900 W to 1,500 W across two heat settings. At 1,500 W it draws 12.5 A and costs about 27.5 cents an hour at the U.S. average rate; at 900 W it draws 7.5 A and costs about 16.5 cents an hour.
Lasko's product page does not mention one. It publishes a cool-touch housing, automatic overheat protection and an ETL listing, but no tip-over switch and no child lock. Because it is a tall, narrow, 7.29 lb tower, confirm this on the unit or with Lasko before using it anywhere it could be knocked over.
Yes. Lasko publishes an 8-hour timer and an included remote that adjusts both the oscillation and the thermostat, plus an adjustable thermostat with a digital display.
Yes — Lasko's product page states it is ETL listed, meaning it was tested to the applicable safety standard by a nationally recognized testing laboratory. It also carries a 3-year warranty.
Lasko does not publish a usable noise figure — its spec table lists 0 dBa, which cannot be a real measurement for a heater with a fan. It is an oscillating fan-driven ceramic tower, so expect it to be audible. If silence matters, a fanless oil-filled radiator or mica panel is the better type.
The default type, and usually the right one. Four picks, and the rare coverage claim that survives the math.
The only feature that actually cuts the bill, because it is the only one that turns the heater off.
Tip-over, overheat, cool-touch and child lock — four mechanisms, four different failures prevented.
Digital thermostat, 8-hour timer and a 3-year warranty at the budget end — and no child lock.
150 sq ft needs about 1,500 W — one heater exactly, with no margin. Here is what that means.
Four things worth doing, none of which is opening the cabinet — and the four signs it is finished.
Dreo has the better feature list and a 300 sq ft claim. Lasko has fewer features and a 150 sq ft claim that checks out.
