heating devices don't have any fans, so they don't circulate dust or allergens and will never dry out the air. They're also silent and and the wall-mount feature offers energy AND space efficiency; these type of heaters can manage to heat up 40% more space than regular heaters. Wall Mounted Lego Radiator: Anything made in Legos is awesome as you can see here. This heater is great for kids rooms. The little Lego studs add heating surface area to make it more efficient. In a world where all radiators and heaters look like a plumbing art project, these are an unique approach. We love it and can only smile overtime we see one. Envi by eHeat: We think this unit is pretty elegantly designed and priced right at $119. It can be used as a single source for heating a room. Since they have a super small footprint, they are perfect for bathrooms and small bedrooms. We like the fact that is 100% pure convection heater using the least amount of energy possible. Easy to clean, since there are no moving parts and is not a dust magnet, that can create a fire hazard. Being cold to the touch is an added safety feature for homes with kids. Check out our Test Lab review of the Envi here. Ceramic Wall Heater: This is an everyday, regular use item that went on and above on the design department. A design by Andrey Vostrikov that not only manages to marry and combine functionality and design but also, making the unit smaller than the competition without any degradation in performance. Besides the fast acting heating element and quieter fan operation this unit is also energy efficient. A welcome concept that we would like to see in the near future.
