# Best oil-filled radiator heater: every 1500 W radiator makes the same heat, so the maker pages sort them by tip-over switch, lab listing, thermostat range and weight > Maker pages compared: Dreo 153 600/900/1500 W, 7 fins, 41-95 F, 17.9 lb; Dreo 310 alone prints ETL listed; De'Longhi EW7707CM 23.37 lb, no tip-over switch. | | | |---|---| | Source | https://ownerspec.com/air/reviews/best-oil-filled-radiator-heater/ | | Publisher | OwnerSpec (https://ownerspec.com/) | | Published | 2026-10-09 | | Updated | 2026-10-09 | | Facts verified | 2026-10-09 | | Disclosure | Contains affiliate links.

The Dreo 310 (DR-HSH010) is the pick for controls and paperwork: the only maker page here that prints ETL listed, with a 1 to 24 hour timer, a remote and the same 41 to 95 F range. The De'Longhi EW7707CM is the documented classic, 7 fins, 3 settings, 23.37 lb and a 2-year warranty, but its page prints no tip-over switch. Heat is not a tiebreaker: Missouri DNR's fact sheet PUB2849 calls every electric resistance heater 100 percent efficient, so each radiator here makes the same heat at 1,500 W and draws 12.5 A on a 120 V circuit. Skip all of them if you want warm air within minutes: a radiator has no fan. ## Fact sheet - **Answer:** Every oil-filled radiator here makes the same heat at 1,500 W and draws 12.5 A on a 120 V circuit (Missouri DNR PUB2849; Lasko support), so the maker pages decide. The Dreo 153 prints 600/900/1500 W, 7 fins, a 41-95 F thermostat, tip-over shut-off and 17.9 lb; the Dreo 310 is the only page printing ETL listed; the De'Longhi EW7707CM prints 23.37 lb and a 2-year warranty but no tip-over switch. - **Comparison basis:** Manufacturer product pages for the Dreo 153 and 310, De'Longhi EW7707CM and Dragon TRD40615E, Hykolity WHG-1606-N4 and Pelonis HO-0279, plus the De'Longhi EW7707CM instruction manual, compared on wattage settings, fin count, thermostat type and range, tip-over switch, overheat protection, printed lab listing, timer, weight and warranty; Missouri DNR for the 100 percent efficiency statement; ESFI, Lasko and Vornado for the circuit figures; NFPA for the features to choose. - **Assumptions:** A standard US 120 V household outlet; every radiator here is rated 1,500 W on high, which the Vornado owner's guide and Lasko's support page put at 12.5 A; 'Not printed' means the maker page read on 2026-10-09 does not list the feature; it is not proof the heater lacks it; The match between each Amazon listing and the maker model comes from the listing's title and the Amazon catalog, not from a maker document; the two Dreo listings in particular were matched by their listed features (remote and 24 h timer for the 310, knob controls for the 153); No maker prints a warm-up time, a heat-retention time or a surface temperature, so the page gives none - **Method:** OwnerSpec compared manufacturer-published specifications read on 2026-10-09 and confirmed each linked listing in stock the same day. No heater was run, timed, measured or used, and the page reports only the figures the cited document states. Prices on the product cards are Amazon's live figures and are never written into this page. - **Primary source:** [Dreo, Oil-Filled Radiator 153 (DR-HSH033) product page](https://www.dreo.com/products/oil-filled-radiator-153) (manufacturer or vendor document) - **Facts verified:** 2026-10-09 - **Last updated:** 2026-10-09 - **Canonical URL (cite this):** https://ownerspec.com/air/reviews/best-oil-filled-radiator-heater/ If you want to feel heat within minutes, this is the wrong page: a radiator warms its oil before the room, and the [oil-filled radiator vs ceramic heater](/air/guides/oil-filled-radiator-vs-ceramic-space-heater/) guide explains why the fan wins that race. ## How was this shortlist built? OwnerSpec compared manufacturer-published specifications on 2026-10-09 and confirmed every linked listing in stock the same day. Nothing on this page was run, timed, measured or used. The fields compared are the ones a radiator maker actually prints: wattage settings, fin count, thermostat type and range, tip-over switch, overheat protection, lab listing, timer, weight and warranty. "Not printed" is a reason to check the carton, not proof the feature is missing. Two makers are absent for cause. No Honeywell oil-filled radiator (HZ-789 or HZ-690) appeared as a buyable listing and Honeywell's manual would not open, so Honeywell has no row. Pelonis's HO-0279 has a row from its maker page but no listing could be matched to it, so it has no pick. Heat does not sort them. Missouri DNR's fact sheet PUB2849 states that all electric resistance heaters are considered 100 percent efficient because there is no heat loss through ducts or combustion. A resistance heater makes heat by passing current through a resistance, which is every radiator here. "Energy saving" in a listing title describes the thermostat cycling, not the element. ## How do the radiators compare on paper? Every figure is the maker's own, as printed on the page or manual cited. | Model | Settings | Fins | Thermostat | Tip-over switch | Overheat protection | Lab listing | Weight | Warranty | | --- | --- | --- | --- | --- | --- | --- | --- | --- | | Dreo 153 (DR-HSH033) | 600/900/1500 W | 7 M-shaped | Stepless knob, 41-95 F | Printed (auto shut-off if tipped) | Printed (auto shut-off) | Not printed | 17.9 lb | 12 months | | Dreo 310 (DR-HSH010) | 600/900/1500 W, eco | 7 | Digital, 41-95 F in 1 F steps | Printed (tilt protection) | Printed (triple) | ETL listed | Not printed | 12 months | | De'Longhi EW7707CM | 3 settings, 1500 W max | 7 | Room thermostat plus safety thermostat, antifreeze at about 41 F | Not printed | Printed (thermal cut-off) | Not printed | 23.37 lb | 2 years | | Hykolity WHG-1606-N4 | 1500/900/600 W | 7 M-shaped | Digital, range not printed | Printed (tip-over switch) | Printed (triple) | Not printed | Not printed | Not printed | | De'Longhi Dragon TRD40615E | 1500 W max, settings not printed | Not printed | Digital panel with LED display | Not printed | Printed (thermal cut-off) | Not printed | Not printed | 2 years | | Pelonis HO-0279 (no listing matched) | 600/900/1500 W | Not printed | Adjustable | Printed (auto shut-off) | Printed (sensor) | Not printed | Not printed | 1 year limited | Three things stand out. A tip-over switch is printed by Dreo, Hykolity and Pelonis and by neither De'Longhi page, though NFPA's tip sheet names auto shut-off on tip-over as a feature to choose. A lab listing is printed once, by Dreo for the 310, without a standard number, so this page names none. Only De'Longhi (23.37 lb) and Dreo (17.9 lb) print a weight. Current is the same across the row: a 1,500 W heater on 120 V draws 12.5 A (Lasko's support page prints about 12.5 A on high and about 7.5 A at 900 W; Vornado's MVH owner's guide says up to 12.5 A). ESFI's booklet puts a 15 A circuit at 1,800 W and recommends staying under 80 percent, 1,440 W or 12 A. The arithmetic is in the [space heater tripping the breaker](/air/guides/space-heater-tripping-breaker-watts-amps/) guide, and the [space heater running cost calculator](/air/calculators/space-heater-running-cost-calculator/) turns the setting into a monthly bill. ## Dreo 153: buy it or skip it? Buy it for a knob you can turn in the dark and a maker that prints its numbers. Dreo's 153 page prints 600, 900 and 1500 W, 7 M-shaped fins, a stepless thermostat from 41 to 95 F, automatic shut-off if the unit is tipped or overheats, 17.9 lb, 12.83 by 9.92 by 26.14 in, a 250 sq ft figure and a 12-month warranty. The flaw is the paperwork. The 153 page prints no ETL or UL mark, while Dreo's own 310 page does, and the warranty is 12 months against De'Longhi's 2 years. The 250 sq ft figure is a coverage claim with no insulation stated; De'Longhi's Dragon page limits a radiator of the same 1,500 W to well insulated spaces or occasional use. Skip it if you want a timer: the 153 page prints none. The Dreo 310 prints 1 to 24 hours. ## Dreo 310: buy it or skip it? Buy it if the listing line decides. Dreo's 310 page is the only maker page here that prints ETL listed, alongside tilt protection, triple overheat protection, 600, 900 and 1500 W plus an eco mode, a thermostat from 41 to 95 F in 1 F steps, a 1 to 24 hour timer, a remote, a child lock and 12.2 by 9.84 by 26.06 in. The flaw is what the spec list leaves out: no weight, no coverage figure, no amp rating, and the same 12-month warranty as the 153. Dreo also prints a 92.3 percent efficiency figure with no method behind it; this page uses Missouri DNR's 100 percent instead. Skip it if you would rather not have a lit panel in a bedroom at night: the page prints a screen-off mode, and the Dreo 153 page describes knob controls. ## De'Longhi EW7707CM: buy it or skip it? Buy it if the manual matters as much as the heater. De'Longhi's page prints 1500 W, 3 power settings, 7 fins, a room thermostat plus a safety thermostat, a thermal cut-off, castors, 23.37 lb, 5.9 by 13.78 by 24.9 in and a 2-year warranty. The manual adds what other makers skip: the thermostat senses room air rather than radiator temperature, an antifreeze position holds about 41 F, and a safety device switches the heater off if it overheats. The flaw is the two features NFPA says to choose and De'Longhi does not print: no tip-over switch on the page or in the manual, and no lab listing. The manual's placement rules are stricter than a bedroom buyer expects: not near a bed, because pillows or blankets can fall onto it, at least 3 feet (90 cm) clear in front and above, not in bathrooms or laundry areas, and not in rooms under 43 sq ft. First use is two hours at maximum with ventilation. Skip it if a child or a dog shares the room: the Dreo 153 prints the tip-over shut-off and weighs about 5.5 lb less. ## Hykolity WHG-1606-N4: buy it or skip it? Buy it for a digital thermostat, a 24-hour timer and a printed tip-over switch. Hykolity's page prints 1500, 900 and 600 W, 7 M-shaped fins, a digital thermostat, a tip-over switch, triple overheat protection, a 24-hour timer, power memory, an ECO mode, a child lock and 4 castors. The flaw is how little else the page prints: no weight, no dimensions, no thermostat range, no warranty term and no lab listing. It has the thinnest maker document of the five picks, which is why it sits fourth. Skip it if you want a printed warranty term. The De'Longhi EW7707CM prints 2 years. ## De'Longhi Dragon TRD40615E: buy it or skip it? Buy it for De'Longhi's build with a digital panel and a timer. The Dragon page prints 1500 W, a digital control panel with LED display, a 24-hour timer, a thermal cut-off and other built-in safety elements, smart snap wheels and a 2-year warranty. The flaw is that the money buys controls, not heat: the page prints no power settings, no fin count, no weight, no tip-over switch and no lab listing, and says the unit is only suitable for well insulated spaces or occasional use. At 1,500 W it makes exactly what the Dreo 153 makes. Skip it if the step up from the EW7707CM has to buy a feature printed on the spec sheet. The Dreo 310 prints the timer, the tilt switch and the ETL mark. **Check the circuit before the heater** Do not order any of these until you know what else shares the outlet: 12.5 A on high is above the 12 A ESFI recommends on a 15 A circuit, so a television on the same run is the trip Lasko describes. The [breaker guide](/air/guides/space-heater-tripping-breaker-watts-amps/) has the arithmetic, the [best space heater](/air/reviews/best-space-heater/) comparison puts a radiator next to the fan-forced units if fast heat matters after all, and the [deal check](/air/guides/space-heater-black-friday-prime-day-deal-check/) says when the prices on the cards above tend to move. ## What goes wrong? **It stands next to the bed.** De'Longhi's EW7707CM manual says not near a bed, with 3 feet clear in front and above; NFPA prints the same 3 feet from anything that can burn and says to turn the heater off when going to bed. **It shares a circuit.** 12.5 A on high is above ESFI's 12 A figure for a 15 A circuit; the 900 W setting, about 7.5 A on Lasko's figures, leaves room for anything else. **It was bought for a cold house.** De'Longhi's Dragon page limits the radiator to well insulated spaces or occasional use, and Missouri DNR's fact sheet makes every 1,500 W unit's heat identical. A room that will not hold heat is a furnace or envelope problem; the [thermostat setback calculator](/air/calculators/thermostat-setback-savings-calculator/) shows what the central system costs instead. **It was bought for the look of a fire.** For a flame effect in a living room, the [best electric fireplace heater](/air/reviews/best-electric-fireplace-heater/) comparison covers units with the same 1,500 W element behind glass. ## The picks - **Dreo 153 oil-filled radiator (DR-HSH033)**: Wants a knob thermostat, a printed weight and a tip-over switch at the lower price (Dreo 153 product page: 600/900/1500 W, 7 M-shaped fins, stepless thermostat 41-95 F, shuts off if tipped or overheated, 17.9 lb, 12.83 x 9.92 x 26.14 in, 250 sq ft, 12-month warranty; the page prints no ETL or UL listing) Amazon: https://www.amazon.com/dp/B0FHKH1TVZ/?tag=ownerspec-20 - **Dreo 310 oil-filled radiator with remote (DR-HSH010)**: Wants a 1-24 h timer, a digital thermostat and the one maker page here that prints a lab listing (Dreo 310 product page: 600/900/1500 W plus eco mode, 7 fins, thermostat 41-95 F in 1 F steps, tilt protection, triple overheat protection, ETL listed, 1-24 h timer, remote, 12.2 x 9.84 x 26.06 in, 12-month warranty; weight not printed) Amazon: https://www.amazon.com/dp/B0C6XLMXY4/?tag=ownerspec-20 - **De'Longhi EW7707CM oil-filled radiator heater**: Wants the longest-documented radiator and a 2-year warranty, and accepts no tip-over switch printed (De'Longhi product page: 1500 W, 3 power settings, 7 fins, room thermostat plus safety thermostat, thermal cut-off, castors, 23.37 lb, 5.9 x 13.78 x 24.9 in, 2-year warranty; the page and the manual print no tip-over switch and no lab listing) Amazon: https://www.amazon.com/dp/B000TGDGLU/?tag=ownerspec-20 - **Hykolity 1500 W oil-filled radiator, 7 M-shaped fins (WHG-1606-N4)**: Wants a digital thermostat, a 24-hour timer and a tip-over switch printed by the maker (Hykolity product page: 1500/900/600 W, 7 M-shaped fins, digital thermostat, tip-over switch, triple overheat protection, 24-hour timer, power memory, ECO mode, child lock, 4 castors; weight, warranty and lab listing not printed) Amazon: https://www.amazon.com/dp/B0GHQ6SFPZ/?tag=ownerspec-20 - **De'Longhi Dragon Digital TRD40615E oil-filled radiator**: Wants De'Longhi's digital panel and 24-hour timer and will pay for the controls, not extra heat (De'Longhi product page: 1500 W, digital control panel with LED display, 24-hour timer, thermal cut-off, smart snap wheels, 2-year warranty; power settings, fins, weight, tip-over switch and lab listing not printed) Amazon: https://www.amazon.com/dp/B00G96S4Y8/?tag=ownerspec-20 ## Frequently asked questions ### Is an oil-filled radiator cheaper to run than a ceramic heater? Not at the same wattage. Missouri DNR's space heater fact sheet PUB2849 states that all electric resistance heaters are considered 100 percent efficient because there is no heat loss through ducts or combustion, so a 1,500 W radiator and a 1,500 W ceramic heater make the same heat. Missouri DNR's example cost is 1,500 W for 10 hours at $0.10 per kWh, $1.50, whichever type runs. ### How many amps does a 1500 W oil-filled radiator draw? 12.5 A on a 120 V circuit, because amps are watts divided by volts. Lasko's support page puts a 1,500 W heater at about 12.5 A on high and about 7.5 A at 900 W, and Vornado's MVH owner's guide says any 1,500 W heater draws up to 12.5 A. ESFI's booklet recommends staying under 12 A on a 15 A circuit, so the radiator gets the outlet to itself. ### Which oil-filled radiators print a tip-over switch? Of the pages read for this comparison, Dreo prints a tip-over or tilt shut-off for both the 153 and the 310, Hykolity prints a tip-over switch for the WHG-1606-N4, and Pelonis prints a tip-over switch for the HO-0279. De'Longhi's EW7707CM page and its instruction manual print a thermal cut-off and a safety thermostat but no tip-over switch, and the Dragon TRD40615E page prints none either. ### Can an oil-filled radiator run all night in a bedroom? The makers' placement rules decide, not the type. De'Longhi's EW7707CM manual says not to place the appliance near a bed, because pillows or blankets can fall onto it, and to keep anything that burns at least 3 feet from its front and top. NFPA's tip sheet says to turn a portable heater off when going to bed. The absence of a fan is the only bedroom argument. ### Which oil-filled radiator is ETL or UL listed? Only Dreo's page for the 310 (DR-HSH010) prints ETL listed among the pages read, and it prints no standard number. The Dreo 153, De'Longhi EW7707CM and Dragon, Hykolity and Pelonis pages print no listing at all, which is not proof they lack one: NFPA says to look for the seal of a qualified testing laboratory, so check the carton or the plate on the unit. ## Sources - [Dreo, Oil-Filled Radiator 153 (DR-HSH033) product page](https://www.dreo.com/products/oil-filled-radiator-153) (manufacturer or vendor document) - [Dreo, Oil-Filled Radiator 310 (DR-HSH010) product page](https://www.dreo.com/products/oh310-radiator-heater) (manufacturer or vendor document) - [De'Longhi, ComfortTemp EW7707CM-6A product page](https://www.delonghi.com/en-us/comfort-temp-full-room-radiant-heater/p/EW7707CM-6A) (manufacturer or vendor document) - [De'Longhi, EW7707CB-EW7707CM Instructions for use (PDF)](https://dls.delonghigroup.com/files/docs/5/A1-5710811251.pdf) (manufacturer or vendor document) - [De'Longhi, Dragon 4 TRD40615E oil-filled radiator product page](https://www.delonghi.com/en-us/p/radiator-space-heater-trd40615e-dragon-4-oil-filled-radiator/TRD40615E-6A.html) (manufacturer or vendor document) - [Hykolity, Oil Filled Radiator Heater 1500W for Large Room product page](https://www.hykolity.com/products/hykolity-oil-filled-radiator-heater-1500w-electric-space-heater-for-large-room) (manufacturer or vendor document) - [Pelonis, HO-0279 1500-Watt Oil-Filled Radiant Space Heater](https://us.pelonis.com/shop/1500-watt-oil-filled-radiant-electric-space-heater-with-thermostat/) (manufacturer or vendor document) - [Missouri DNR, Space Heaters fact sheet PUB2849](https://dnr.mo.gov/document-search/space-heaters-pub2849/pub2849) (government or regulatory source) - [ESFI, Indoor Electrical Safety Check booklet (PDF)](https://www.esfi.org/wp-content/uploads/2021/08/Indoor-Electrical-Safety-Check-Booklet-3FB3.pdf) (manufacturer or vendor document) - [Lasko support, Heater is tripping the breaker.
