The Presto HeatDish Plus parabolic electric heater uses a computer-designed parabolic reflector to focus heat, like a satellite dish concentrates TV signals. It feels three times warmer than 1,500 watt heaters, yet uses a third less energy. The HeatDish Plus warms you directly. You feel the heat almost instantly without first heating the room. Because the heater uses just 1000 watts, it can help save enough on electric bills to pay for itself in as little as one year
