Specs, owner feedback and who it suits." canonical: https://vettedten.com/household/electric-heaters/oil-filled-radiators/delonghi-radia-s-trrs0715e/ language: en-GB updated: 2026-11-09 score: 7.9 --- # De'Longhi Radia S TRRS0715E review > **Our verdict:** The De'Longhi Radia S TRRS0715E ranks 9th of the 10 oil-filled radiators we compare, with 7.9 out of 10. No. 9 of 10 in our [oil-filled radiators ranking](https://vettedten.com/household/electric-heaters/oil-filled-radiators/) · Updated November 2026 · [How we rank](https://vettedten.com/how-we-rank/) **7.9 out of 10** The De'Longhi Radia S TRRS0715E is a 1500W oil-filled radiator with a digital LED panel, 24-hour timer and Eco mode. It suits a well-insulated bedroom or home office, not a large or draughty room. Why it's here: - Digital LED panel with 24-hour timer - Eco function that adjusts power as the room warms - Child lock and anti-frost setting - Slim body with pre-fitted wheels Keep in mind: - 1500W tops out below the 2000W and 2500W models here - Brand says it suits well-insulated rooms - Pricey for the output [Check price on Amazon](https://www.amazon.co.uk/dp/B07KMQDJC4) ## Why the De'Longhi Radia S TRRS0715E scores 7.9 - How happy owners are: 7th of 10 - How many rated it: 9th of 10 - How new it is: 5th of 10 ### Level with the Warmlite WL43002YW 650W Oil Filled Radiator The Warmlite WL43002YW 650W Oil Filled Radiator and the De'Longhi Radia S TRRS0715E score the same, so either is a safe pick. The Warmlite WL43002YW 650W Oil Filled Radiator goes first because it has been rated by more owners. ## About the De'Longhi Radia S TRRS0715E The Radia S is a portable oil-filled radiator rated at 1500W. It has no fan, so it warms a room through its fins and gives out no moving-air noise or dust. The oil reservoir is permanently sealed and never needs topping up. De'Longhi says the design has up to 35% more radiant surface than its earlier models. Controls sit on a digital LED panel. You set a temperature, and a 24-hour timer switches the heater on and off at times you choose. The Eco function adjusts heat and power as the room reaches the set temperature. De'Longhi calls its approach Real Energy and says it is up to 20% more efficient. A carry handle and snap-fit wheels let you move it between rooms. The box holds the radiator, and the manual and quick-start guide are on De'Longhi's support pages. The brand states plainly that the heater is only suitable for well insulated spaces or occasional use. ### Key specs - Power: 1500W - Type: Portable oil-filled radiator, no fan - Controls: Digital LED control panel - Timer: 24-hour - Eco function: Adjusts heat and power automatically - Oil reservoir: Permanently sealed, no refilling - Moving it: Carry handle and snap-fit wheels - Warranty: Full manufacturer warranty (duration not stated on the brand's page) ## What owners report about the De'Longhi Radia S TRRS0715E We found little owner feedback for the UK model. What follows comes from reviews of the same model code on an Australian retailer's site, so treat it as a guide rather than a UK verdict. Owners there say it warms a small to medium room and holds a steady, comfortable temperature. It heats quickly on the top setting and can then be turned down. They call it quiet and find the digital controls easy to use. The complaints are small. Some hear a ticking noise as it starts up, and the beep when the timer is set is louder than expected. A few find the instruction manual unclear. We found nothing solid on how it holds up after months of use. ## Who the De'Longhi Radia S TRRS0715E suits It suits a bedroom, home office or box room that is reasonably well insulated, where you want a quiet heater on a timer. The slim body and wheels make it easy to shift between rooms. Look elsewhere for a big or draughty room: at 1500W it gives less heat than the 2000W and 2500W models in this guide, and De'Longhi itself limits it to well-insulated spaces. The VonHaus 11 Fin Oil Filled Radiator 2500W with Timer is the better fit there. For a lower outlay with similar output, the Russell Hobbs RHOFR7004B is a plainer 1500W option. ## Questions about the De'Longhi Radia S TRRS0715E ### How many watts is the De'Longhi Radia S TRRS0715E? 1500W.

Too few review sites cover oil-filled radiators for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 32 models for this guide before settling on these ten. Brands can't pay to be included or to move up. We last checked these picks in October 2026.
