De'Longhi TRD40615T Full Room Radiant Heater Heater-Mechanical-TRD40615T, 10"w x 15"d x 26"h, White

This is an excellent radiator that puts out a lot of heat with almost no noise and no smell. I used an infrared thermometer to measure the temp at the top and sides after 30 min on max. The top got to 368F while the sides didn't get over 160F. 368F sounds dangerous but I can still put my hand on top for a few seconds before I have to take it away so I'm not worried at all about burns if someone accidentally touches the heater. The temp difference between the top and sides shows that the thermal chimney design really works well. It draws cold air in from the bottom, dumps all of its heat into the air and then accelerates the air out of the top using only convection. No moving parts but it heats the air so well that there's a noticeable "breeze" of hot air that rises straight up from the heater. I have noticed some very faint clicks that the heater makes as it operates. The thermostat clicks softly when it turns on and off and rarely I'll hear a pop from the metal expanding while it heats or cools down. None of the noises are loud or distracting but I've seen a lot of comments asking if it makes ANY noise. It does, but I don't know how someone could make a quieter heater than this one. I've also seen a lot of reviews asking of there was a smell. I ran mine on high for a few hours when I first got it to burn off any smell there was. If I stuck my face right above the heater, I guess I could smell something like fresh paint/metal but it was very faint and not noticeable in the room. I've been running it for a few days now and nobody has noticed a smell. Definitely better than that "first time you turn it on" smell of a ceramic heater. We use this unit for secondary heat in a very large bedroom with vaulted ceilings that used to be a living room. When used with a fan near the ceiling to circulate air it let's us keep the house pretty cold while our room stays comfortable if we're wearing a light jacket. I let it run on max for a few hours the first day and came back to a 75 degree room when it was 25 outside so it's definitely capable of heating a large room, but the electric bill would probably be insane if this is the only heat source you use. All in all I'm extremely happy with this heater. It's the most I've ever spent on a space heater but it's solidly built, works well and when used with the timer should hopefully pay for itself this year.

Works well. Def recommend oil heaters (like this) instead of electric. Like how the heat rolls out through the room slowly instead of being blasted out. Easy to roll. And like the ones used in old houses with no central heating. Decently priced.

Excelente calenton, inclusive para espacios amplios, es muy manual por lo cual lo puedes acomodar casi en cualquier rincon, el nivel de confort es muy bueno, no esperes que de un temperatura de playa en un dia muy frio, pero si te mantendra comodo en dias de invierno, yo lo tengo en una habitacion de 16.00m2 y en una de 25.00m2 y funciona muy bien en las dos, el consumo, como cualquier aparato electrico, dependera del tiempo y la potencia que trabaje, pero en mi experiencia de uso, el calento consume menos energia estando prendido siempre, pues al estarlo apagando dejas que la habitacion se enfrie y si le toma un poco de tiempo llegar a templar el clima, lo cual lo hace consumir mas energia.

Quiet and effective. Heats a larger area than I expected.

This is our second heating season with this radiator and we are quite surprised with it's ability to heat a fairly large area. The radiator is used in a small house with a cathedral ceiling, loft bedroom, living room, kitchen, bathroom and first floor bedroom, an area of approximately 800 square feet. There is a fan in the cathedral ceiling which gently pushes the rising heat downward, dispersing heat throughout the house. We have other heating sources, a propane heating system and wood stove, but the De'Longhi allows us to warm the living area longer into the winter season before turning to our other heating sources. We live in northern New England and the winters can be extreme here. This radiator will keep the house at a comfortable temperature even down to 30* F. We like the built in thermostat which is a simple dial that you can adjust when the temperature is at a level you wish to maintain. The radiator will then click on when more heat is needed and click off when the room has reached the desired temperature. There is also a built in timer that you can set manually that will turn the radiator on or off at any desired time you wish. We have not noticed a big difference in our electric bill, as this is just one oil filled radiator, not a house with baseboard heat run on electricity. One reviewer was not happy with the crackling sound the radiator makes when it starts up from cold. This lasts for about five minutes, only on initial startup and we do not find it intrusive. I don't know why this occurs. We have another De'Longhi which I purchased 32 years ago and is still running fine, that does not make this noise. If you are looking for an oil filled radiator to provide supplemental heat, the De'Longhi warrants consideration.
