- Choose ceramic for fast, directed warmth, oscillation and a light, compact body.
- Choose oil-filled for fan-free, near-silent heat that PELONIS says avoids dryness.
- Same top output: both PELONIS families top out at 1500W, and both list tip-over and overheat protection on the models compared here.
- Our two reference models: the 23-inch PHF15RSAPH23 ceramic tower and the PSHO06MR6ASB oil radiator.
The ceramic vs oil filled heater question comes down to speed versus silence. A ceramic heater uses a fan to push warm air out in seconds; an oil-filled radiator has no fan and gives off steady, quiet warmth once its oil heats up.
PELONIS sells both types, so this guide compares them using the brand's own listings, with the 23-inch ceramic tower and the PSHO06MR6ASB radiator as reference models. Want a ranked list instead? See the best ceramic space heater and best oil filled radiator heater guides.

PELONIS 23‘’ Oscillating Ceramic Tower Space Heater with Timer & Remote

Check price →Which heats up faster?
Ceramic wins on speed, and it is not close on paper. PELONIS claims its 23-inch tower heats up to 70°F in 3 seconds, and the small PSHC09D2SB claims fast heat in 2 seconds. Air moves straight out of the fan, so you feel it right away, and oscillation spreads it across the room. That makes ceramic the natural fit for rooms you only use for an hour or two, like a home office, a craft room or a guest room you warm up only when visitors arrive.
An oil-filled radiator warms its oil first and then the room, so it takes longer to feel. PELONIS describes the payoff as long-lasting, gentle warmth and 360° hot air circulation without dryness.
Which is quieter?
Oil-filled wins on noise. With no fan structure, the PSHO06MR6ASB listing claims almost 0dB, and the 7-fin models describe pure silence once heating stabilizes. The quietest PELONIS ceramic model, the 16-inch PSH17CD2ABB, is listed as low as 32dB, and the 23-inch tower under 55dB. If you are sensitive to a steady fan hum at night, that difference is the main reason to lean toward a radiator.
Listed noise: ceramic vs oil-filled
dB as stated by PELONIS; the 23" tower figure is an upper bound (<55dB)
Settings, timers and controls
The oil radiator gives three fixed wattage steps, which makes it easy to run at 600W on a mild night. The ceramic tower uses High and Low plus ECO, and adds a fan-only mode for summer.
Longest timer setting
Hours, as listed
Both reference models have a remote. Among the knob-only models, the PELONIS PHO15A2AGW and 7-fin oil radiators have no timer listed, and neither does the PH-19J ceramic heater.
Size, placement and the wider PELONIS range
The ceramic vs oil filled heater choice also depends on where the heater will live. PELONIS ceramic models range from an 8.35-inch desktop cube to a 30-inch tower, while its oil radiators are floor units on casters; the PHO15A2AGW lists 26.10 x 14.20 x 11.00 inches.
| Type | PELONIS models | Best placement |
|---|---|---|
| Ceramic tower | 23" PHF15RSAPH23, 30" PHF15RSAPH30 | Bedroom or living-room floor |
| Compact ceramic | 16" PSH17CD2ABB, PH-19J | Floor, desk or under a desk |
| Desktop ceramic | PSHC09D2SB (3.1 lb) | Desk, nightstand, tabletop |
| Under-desk ceramic | PSHCD12M4ABV (1200W) | Floor, vertical or horizontal |
| Oil radiator, digital | PSHO06MR6ASB | Bedroom floor, on wheels |
| Oil radiator, knobs | PHO15A2AGW, PSHO07JM1AGB, PSHO15M2 series | Any room floor, on casters |
One more point in the ceramic vs oil filled heater debate: ceramic models that oscillate can sweep warm air across a seating area, while a radiator warms the air around it in every direction. If you sit in one spot, ceramic aims heat at you; if you want the whole room gently warmed, the radiator suits that better, going by how PELONIS describes each type.

- Need warmth right now? Pick ceramic. It is the better choice for a cold office or a quick warm-up after a shower.
- Sleeping next to it? Pick oil-filled for fan-free quiet, or the 32dB ceramic PSH17CD2ABB if you also want oscillation.
- Heating under a desk? Ceramic. The 1200W PSHCD12M4ABV is built for floor-level warmth.
- Want year-round use? Ceramic towers with a Fan mode double as a light fan.
- Moving it a lot? Ceramic is lighter; oil radiators roll on wheels.

Planning for summer too? Pair either one with a fan from our best quiet fan list.
In the ceramic vs oil filled heater decision, ceramic is the pick for speed, directed heat and oscillation. The 23-inch PELONIS tower heats in seconds, sweeps 75° and adds a fan mode.
Oil-filled is the pick for quiet, steady warmth. The PSHO06MR6ASB has no fan, three wattage steps, a 41-95°F thermostat and a 24H timer. Both list tip-over and overheat protection, so choose by how fast you want heat and how much noise you will accept.
