Lasko Ellipse 12-inch Ceramic Space Heater (CD12950 / CD12951) review

Lasko’s Ellipse CD12950 (Black) and CD12951 (Silver) are finish variants of one 12-inch tabletop ceramic heater, not two different control packages. The shared design combines three heat levels, two fan-only speeds, a thermostat, base oscillation, a 12-hour shutoff timer and an included remote. Its compact body is useful only if the whole safe operating area fits: the manual calls for a stable, level surface and at least 3 feet in front and 1 foot at the sides and rear from combustible material.

Small body, surprisingly large placement zone

The official product page lists a body just under 12 inches tall, with a 6.11-inch width and 4.86-inch depth. That can sit on a suitably broad desk, counter or bedside table, but tabletop size alone is a poor fit test. Lasko’s instructions require clear air intakes and exhaust, a stable flat surface and the full combustible-material clearances. In a crowded office, paper piles, curtains, bedding and nearby furniture may make the proposed spot unsuitable even though the heater itself is small. The manual says not to set it on a soft surface such as a bed.

There is also a practical electrical constraint. Plug it directly into a 120-volt wall receptacle; do not use an extension cord, power strip, surge protector or multi-outlet adapter, and do not share the circuit with other devices. The manual asks owners to check that the plug fits firmly and is not overheating. That makes a clear, reachable wall outlet part of the layout—not an accessory detail. Lasko markets the heater for small and medium rooms and lists coverage up to 200 square feet, but that is a maker claim, not a room-heating result we independently measured.

Three heat levels and two fan-only speeds

The exact CD12950/CD12951 manual labels high, medium and low heat, plus separate F1 and F2 fan-only settings. Fan-only moves existing room air; it does not cool it. The manufacturer page lists a 750–1,500-watt overall range and a 1,500-watt maximum, but the sources do not assign a wattage to each of the three heat levels, so a buyer should not treat the selector as a precise wattage scale.

An automatic thermostat can cycle heat around the temperature displayed for the room: the manual says the heater switches off about 2 degrees above the set temperature and resumes about 1 degree below it. Auto and Eco modes behave differently; Eco uses the lower heat setting for temperature control. The display reports room temperature, not the temperature of the outlet air. Lasko’s page describes wide-angle oscillation and 120-degree heat distribution. The manual confirms a base-oscillation control, but the cited sources do not establish a numeric sweep arc. If a minimum number of degrees is essential, do not translate the 120-degree distribution wording into an oscillation measurement.

Remote conveniences, with important limits

The supplied remote can change heat and fan settings, temperature, oscillation and the timer; it also selects Auto, Eco or Sleep and can turn the display off. It requires two AAA batteries that are not included. The top display automatically dims after ten seconds. A three-second child-lock hold disables the heater’s functions except Power, and settings already active remain on. That is a useful control limitation to understand, not a childproofing substitute or a way to prevent the heater from being powered down or operated.

The countdown can be set for up to 12 hours. It switches the heater off; it is not a delayed-start schedule. Sleep Mode turns the display off, keeps the current setting for an hour and then moves to low-heat automatic temperature control at the manual’s stated 68°F sleep target. Do not read “Sleep” as permission to leave the unit operating while you are away or asleep: the manual says the heater should not be left operating unattended. A timer, thermostat, sleep sequence and control lock do not override that instruction.

Keep it dry, attended and clear

The instructions prohibit bathroom use, wet or damp locations, outdoor use and positioning where the heater could fall into water. They also say to keep combustible materials at least 3 feet in front and 1 foot from the sides and rear, to keep the intake and exhaust unobstructed, and to unplug the heater before moving or cleaning it. The manual describes a tip-over switch and thermal-overload protector; if overload shuts it down, unplug it and allow a ten-minute cool-down before following the reset steps. Intake grilles should be vacuumed with a brush attachment about every two weeks. These are exact-model operating instructions, not guarantees that any placement is safe.

Who should choose it—and when to pick another style

Choose the Ellipse if you have a spacious, stable dry-indoor surface, a direct outlet, and want a tabletop heater with fan-only airflow, more than one heat level, a thermostat and remote adjustments. The Black CD12950 and Silver CD12951 are distinguished by finish in Lasko’s native product record; the shared New 1/25 manual identifies both models. A current manufacturer listing and its native option record disagree on product weight, so weight is left unreported rather than guessed from the color or a neighboring listing. The product page’s “under 40 dB” wording also lacks a measurement protocol; it is a manufacturer claim, not an independent noise result.

If you want simpler local controls and do not need the remote or countdown, compare the reviewed Lasko CD09250 / 754200 9-inch tabletop heater. Its manuals describe two heat levels and no timer, while the Ellipse adds remote control, three heat levels and a longer shutoff countdown. Neither choice changes the basic placement rule: follow its own manual, keep the full clearance zone, and do not use a space heater as unattended or wet-area heat. See the Lasko model page and the CD12950/CD12951 New 1/25 manual for the complete current directions.
