De'Longhi Radia S TRRS0715E review

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.

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.
