De'Longhi TRD40615T 1500W Oil Filled Radiator Heater - Portable Electric Space Heater with Programmable Timer & Safety Features for Bedroom, Living Room, Office | Indoor Heating Solution for Winter

I was looking for a safe heater for bedrooms. Our home has no upstairs heat currently and we needed something for each room. Since two of the rooms are kids rooms, I wanted something as safe as possible, and while no space heater is 100% safe, I believe the DeLonghi TRD40415T gets very close.I was a bit wary of radiant heat - how good can that be exactly, with no blower or fan? I recalled days of my own youth relying on hot water radiators to heat the house. Suffice to say, this DeLonghi unit is light years ahead of that technology - granted both radiant heat, but just as rotary phones and iPhones are both "telephones", its hardly the same thing. I was very surprised by both the heat output and feel of the radiant heat - it rises mostly from the top and although I know better, you could be fooled into believing it has a fan - but it doesn't. On Medium, the unit noticeably raised the temperature of a 16 X 16 basement room from chilly to comfortable in around 2 hours. On high, the unit easily pushed the room to overly warm, toasty even. I imagine a High setting would cut the time to "comfortable" by about a third. The unit is easy to operate and settings are mostly intuitive. The only potentially confusing part might be the timer, but only if you have never used a mechanical timer like this before, and once you figure it out, its very easy. The timer is also infinitely flexible, enabling you to set multiple on and off periods. I have the heater kick on at 5am, then off at 8am - so heating the room for morning, then it remains off until 6pm and heats until 8:30pm - so heating the room again before bed.The unit is mostly silent - it may click and tap once or twice upon initial startup, but it is not overly noticeable and seems to diminish with use. Otherwise, the only sound is the timer running, and you can only hear that with your ear directly on the unit - which is a bad idea anyway....The unit does get hot to the touch, particularly on top. On Medium, you may get a 3-5 second count before you must remove your finger from the sides or front, on High, I didn't even attempt to touch it. The sides are somewhat cooler, but no so much that they would not burn with prolonged contact. Ultimately, this is a heater, if therefor must get hot somewhere. The advantages are that there is no exposed heating element, no loud fan, little to no chance of catching something on fire due to a brief accidental contact and burns are unlikely to occur unless handled improperly - you'd sort of have to try burn yourself. The trade-off is a slower heat transfer versus a fan driven heater and the unit is heavy - although the weight does somewhat deter inappropriate positioning and helps resist accidental tip-over and similar accidents.I run the units on medium to maximize safety while still putting out enough heat. Although no space heater should really be left unattended, I feel confident that this unit's passive radiant heat and quiet uncomplicated operation, make it a much more reliably safe option versus other space heating alternatives.
