Primrose IPX4 Wall Mounted Quartz Bulb Electric Patio Heater with 3 Settings in Silver 2kW; The heater works by using heat resistant quartz tubes, which absorb and keep the heating element and stop convection heat from escaping. After becoming hot, the quartz tubes emit safe infrared rays which heat objects around. These great properties help you and your guests feel warm and comfortable quicker. The quartz heating technology has been tried and tested for over 15 years, being the oldest technology if compared with only halogen or carbon heating. The heater is wall mountable and comes included with screws for easy installation. It is also finished with a smart, metal front and white resin corpus, providing a classic and elegant decor for any interior or exterior.
