The DRU electric stoves utilise LED technology for example and as such consume far less energy; just 10 to 20 Watt.
For comparison purposes; other electric stoves available on the market work on a lightbulb and can use 180 to 200 Watt. This means that DRU electric stoves are not only cheaper but are also far more environmentally friendly.
In addition, the average number of burning-hours with an LED are also far higher than with a lightbulb.
