Head-to-head · Brands
One brand gives you more features and a coverage claim to argue with. The other gives you fewer features and a number that survives the math.

Dreo's Solaris 718 publishes more: a 41–95°F digital thermostat in 1°F steps, four oscillation angles, a child lock, a tip-over cutoff and an ETL listing. Lasko's 755320 publishes a 900 W low setting, a 3-year warranty and a 150 sq ft coverage claim that matches the arithmetic exactly — where Dreo's claim is double it.
Both brands sell wide ranges, so a whole-catalog comparison would be meaningless. The head-to-head buyers actually face is between Dreo's flagship oscillating tower and Lasko's digital ceramic tower — similar height, similar shelf, similar money, and very different philosophies about what to print on the box.

Published by each maker for the specific model. "Not published" means we checked their page and it was not there.
Both heaters are 1,500 W. At 10 watts per square foot with average insulation and an 8-foot ceiling, 1,500 W covers 150 square feet. Lasko publishes 150. Dreo publishes 300.
Dreo's figure is not a lie — it implies about 5 W per square foot, which is reachable in a well-insulated, draft-free modern room being topped up rather than heated from cold. But it is the optimistic end of a range presented as a single number, and a buyer with a 300 sq ft room who believes it will be disappointed. Lasko's figure is the conservative, standard-assumption one, and it is the same number our own arithmetic produces without knowing what Lasko said.
Control. A thermostat published as 41–95°F in 1°F increments is a specification; "adjustable with a digital display" is a description. If you want the room at 68°F, the Dreo will do it and the Lasko will get you approximately there.
Safety features, and it is not close. Dreo publishes a child lock and a tip-over cutoff. Lasko publishes neither for this model — and on a 23-inch, 7.29 lb tower, the tip-over switch is the one that matters most. On this site's criteria that single row rules the Lasko out of a nursery and makes the Dreo a candidate. The four tip-over mechanisms.
Oscillation you choose. Four selectable angles against an unspecified sweep. On a heater bought partly for spreading heat, that is the difference between setting the arc and accepting it.
A published low wattage. 900 W is the single most useful number on Lasko's sheet: it drops the running cost from 27.5 to 16.5 cents an hour and the draw from 12.5 A to 7.5 A, which is the difference between being over a 15 A circuit's continuous allowance and comfortably inside it. Dreo publishes no equivalent figure for the Solaris 718.
A published warranty. Three years, stated. Dreo publishes none on its Solaris 718 page. A warranty is the one claim a company cannot make cheaply — it is a costed commitment rather than a line of copy — so its absence is as informative as its presence.
A coverage claim you can trust, which is where this page started.
| 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.
| 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)).

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.

Who it is for
A living room, bedroom or den at or under 300 sq ft with average insulation and an 8-foot ceiling, where you want to set a temperature and stop thinking about it.
What it is not for
A garage, an uninsulated basement, or anything over about 300 sq ft. It is not under-powered — 1,500 W is the plug-in ceiling — the room is simply too big for one outlet.
2 · The maker's coverage claim that matches the arithmetic
A 23-inch digital tower with a thermostat, an 8-hour timer and a remote — and the only heater here whose published coverage figure lands exactly where our own sizing rule puts it.
| Published specification | |
|---|---|
| Rated power | 900 W to 1,500 W (Lasko's published range) |
| Heat settings | Two |
| Thermostat | Adjustable, with a digital display |
| Oscillation | Yes |
| Timer | 8 hours |
| Remote | Included, with onboard storage |
| Size | 23" H x 7.25" D x 7.00" W, 7.29 lb |
| Safety | Cool-touch housing, automatic overheat protection |
| Warranty | 3 years |
| Heat type | Ceramic (PTC) |
| Maker’s coverage claim | 150 sq ft |
| Safety listing | ETL listed, stated on Lasko's own product page. |
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.
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.
If the Lasko's missing tip-over switch is the sticking point but you want Lasko's pricing, the brand's own Ellipse tower publishes both cutoffs — it is on best tower space heaters, where all four towers are ranked on exactly that criterion.
Dreo publishes more features — a 41–95°F thermostat, selectable oscillation, a child lock and a tip-over cutoff. Lasko publishes a 900 W low setting, a 3-year warranty and a coverage claim that matches the standard sizing arithmetic where Dreo's is double it. Both produce identical heat at 1,500 W.
Dreo publishes 300 sq ft. At the standard 10 watts per square foot with average insulation and an 8-foot ceiling, 1,500 W covers 150 sq ft — half that. Dreo's figure implies an assumption it does not state; we publish our computed figure alongside the claim rather than repeating it.
Identical at identical wattage — about 27.5 cents an hour at 1,500 W. The Lasko can be cheaper in practice because it publishes a 900 W low setting at about 16.5 cents an hour, and Dreo publishes no equivalent figure for this model.
The Dreo, on published specifications. It publishes both a child lock and a tip-over cutoff; Lasko publishes neither for the 755320. On a tall, light tower those are the two features that matter most in a room with a small child.
No. Lasko publishes a 3-year warranty for the 755320. Dreo publishes no warranty on its Solaris 718 product page. A warranty is a costed commitment rather than a marketing line, so the absence is worth noting.
1,500 W, a published 300 sq ft claim that survives the arithmetic, and a thermostat with numbers.
900-1,500 W, digital thermostat, 8-hour timer, ETL listed — and a 150 sq ft claim that matches the math exactly.
