Dimplex sees oil-free as a major advance for portable heating as it heats up faster than traditional OFRs and is lighter and easier to move around – for example, the company’s Cadiz Eco range offers the same radiant heat benefits as traditional OFRs, faster and at greater temperatures and is approximately 5kg lighter than the Cadiz OFRs from Dimplex. Pictured is the OFRC20tic oil free, which has a 24-hour timer so that daily heating needs can be programmed in advance.
