Delonghi EW7707CM
The EW7707CM is the model I have used the longest. Seven fins, comfort temperature setting, and a built-in timer. It heats a 150-square-foot room reliably and the casters make it easy to roll between rooms. It is the default Delonghi I recommend because nothing about it is fancy, but everything just works.
I have heated drafty rooms with Delonghi oil heaters for years. Here are the five models worth buying in 2026.
I have used Delonghi oil-filled radiant heaters in my home office, bedroom, and basement workshop for close to a decade. They are quiet, safe, and they distribute heat evenly without the dry, scorched-air feel of fan heaters. Here are the five Delonghi models I would buy in 2026.

Our picks up close
Delonghi EW7707CM
The EW7707CM is the model I have used the longest. Seven fins, comfort temperature setting, and a built-in timer. It heats a 150-square-foot room reliably and the casters make it easy to roll between rooms. It is the default Delonghi I recommend because nothing about it is fancy, but everything just works.
Delonghi TRD40615T
The TRD40615T has a sleeker look with vertical chimneys that channel hot air more efficiently. Digital thermostat is more accurate than the dial version, and the ECO mode saves around 20 percent on runtime by cycling more intelligently. Slightly louder click from the relay, but otherwise silent.
Delonghi KH390715CB
If efficiency matters most, the KH390715CB has the most advanced ECO mode of any current Delonghi. Real-time adjustment of power output keeps the room within a tighter temperature band. Digital display is bright and clear. Slightly pricier, but the runtime savings add up over a winter.
Delonghi EW7507EB
The EW7507EB has wider fin spacing, which gives it more surface area and warms a larger room faster. I use this one in my basement, which is around 250 square feet, and it holds temperature well. The wider footprint is the only real drawback for tight spaces.
Delonghi HMP1500
The HMP1500 is technically a mica panel heater rather than a true radiant, but it is the right pick for tight spaces like a small office or a hallway nook. Wall-mountable, slim profile, and heats up faster than an oil-filled radiator. Cools down faster too, which is the trade-off.
Quick answers
They use the same wattage as any electric space heater at full blast, but because they retain heat in the oil they cycle off more often, which in practice ends up cheaper than a coil heater running constantly.
Yes. All current Delonghi radiant heaters have tip-over and overheat shutoff, and the fins stay warm rather than hot enough to burn skin. I leave mine running in my bedroom all winter.
