The Royal Diamond Silver Infrared Patio Heaters are not only warming but low energy and does not pump CO2 into the atmosphere.
The Royal Diamond range has Golden Tubes. This produces short heat waves, and the wind does not dissipate the heat. A layer of gold leaf provides extra reflection and thus creates a more intense feeling of warmth compared to the Halogen element.
Infrared heaters are cheap to run. A 2 KW (2000W) heater costs between 20-40p per hour.
