"The 400W, 120-Volt wall mounted panel heaters are safe, economical to use and work based on the principle of convective heat transfer. The panels are mounted from the wall to create a convection channel using the hardware provided and requires a simple do-it-yourself installation. Based on the principle of heat convection, the hot air rises and gets displaced by cooler air creating convective air currents within the room that gradually move warmer air to achieve a uniform ambient temperature. The Amaze-heaters do not have built-in fan therefore, there is no noise and no stirred-up dust this eliminates airborne dust problems and it is ideal for people suffering from asthma or allergies. The 400 Watt heater is ideal for a regular size room up to (120 sq. ft.). These units are perfect not only to provide supplemental heat but also to warm up any cold spots in the house. Can be painted to match any decor with latex paint Energy-Efficient - Save up to 70% on heating costs! Triple insulated for electrical safety. Safer for Children, elders and pets. Lower surface temperature will not burn upon contact. No fan and therefore no noise, 100% quiet, great for bedrooms, offices, kitchens, etc. Heat Reflector included - This is a self-adhesive reflective sheet that is stuck to the wall behind the panel and it will minimize heat loss to the wall and increase the efficiency of the heater. A good application is to install the units in rooms that are used during the night and set the central thermostat lower by few degrees. By doing this, you can save on heating costs by not heating the whole house at night 400 Watts, Voltage - 120 V, Current - 3.3 Amps. All panels are supplied with high density foam packing for safe transportation."
