review.whatIsIt

Our family likes this heater a lot during the winter. You can keep it running in bedrooms all night at 67-70 degrees without breaking the bank and without needing to run central heating much at all. It also isn't dry heat but gradually heats the room without constantly moving air. We tried to buy one pre-owned and would not recommend that or the white one (some sticky material at the bottom). The black ones fit in. They're fairly toddler safe too since the heater doesn't get super hot on the sides. It's just a gradual, solid heat.

review.whyWeLoveIt

The DeLonghi Dragon Digital Heater has become an essential part of our winter routine. Its ability to maintain a consistent, comfortable temperature without the noise and dryness of forced-air heating makes it perfect for bedrooms. The energy-efficient ECO mode helps keep costs down, and the safety features give us peace of mind with a toddler in the house. One tip: if you have central heating vents in the room where you're using the heater, consider using a vent damper to close them off. This prevents the dry forced-air heat from competing with the heater and keeps the room more comfortable without the drying effects of central heating.
