The Delonghi dragon 4 1500 watt electric heater heats my entire living room, kitchen, and dining room. It slender design allows me to place anywhere without taking up to much space. I love that it is on wheels because it is easy to move around. I love that it automatically stops heating when it gets to the temperature you have it set to. Its digital panel is very easy to use and easily comprehensible. This steady heat is perfect for keeping the areas of my home warm with a constant heat. Overall I love its slender design, its constant heat and its ease of moving around and use.
