The product is a <strong>fast-heating<\/strong> and <strong>heat-storing <\/strong>infrared heater <strong>with a thermostat<\/strong>. The material is a <strong>full metal housing<\/strong> and the <strong>processing<\/strong> was carried out in <strong>Europe<\/strong>. The wall heater is safely <strong>protected against fire<\/strong> and is <strong>T\u00dcV tested<\/strong> and <strong>certified<\/strong>. The infrared heater is<strong> easy to<\/strong> <strong>install<\/strong> in just a few steps thanks to the <strong>fixing material supplied<\/strong> and the <strong>Quick Up bracket<\/strong> with drilling template. The wall heater is <strong>heated<\/strong> using a <strong>normal power cable<\/strong>. The product <strong>heats<\/strong> the environment<strong>relatively quickly and effectively<\/strong>, without any annoying noises.<br>The infrared heater is available in four <strong>different versions<\/strong>. The 1000 watt heating panel available to us for testing is kept in a plain white colour and is therefore hardly noticeable on white walls. The heater is installed horizontally and is 120 cm wide and 57 cm high. The depth is only 1.5 cm, which means that the appliance blends even more discreetly into the room.<br>The infrared heater has no sharp edges or corners. <\/p><div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\"><div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-uagb-advanced-heading uagb-block-6ba0c837\"><h4 class=\"uagb-heading-text\"><strong>Advantages<\/strong><\/h4><\/div><p>\u2705 Heats up quickly<br>\u2705 Full metal housing<br>T\u00dcV tested and certified<br>\u2705 Made in Europe<\/p><\/div><div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-uagb-advanced-heading uagb-block-f1cbc7b6\"><h4 class=\"uagb-heading-text\"><strong>Disadvantages<\/strong><\/h4><\/div><p>\u274c Wired<\/p><\/div><\/div><div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><div class=\"wp-block-uagb-advanced-heading uagb-block-28399329\"><\/div><div class=\"wp-block-uagb-advanced-heading uagb-block-1a58b887\" id=\"der-erste-eindruck\"><h2 class=\"uagb-heading-text\">The first impression<\/h2><p class=\"uagb-desc-text\">The packaging and labelling<\/p><\/div><div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><p style=\"font-size:14px\">\u2139\ufe0f Here we take a closer look at packaging.
