Our European styled plant covers 26,000 sq.m., housing the most advanced automated production lines, inspection and testing rig from Italy. With annual production capacity up to 200,000x pcs, our product range includes high efficiency condensing boilers, standard efficiency combination boilers, wall hung boilers, floor standing boilers and water heaters. As the first one who introduced the most advanced technology for wall mounted boilers to China, we are also the first one in China gaining CE approval for combination boilers in 2003. So far, our production have been exported to more than 19 countries like Turkey, Ukraine, Armenia, Hungary, Argentina, Greece, Spain, Chile etc. For five consecutive years, we come out No.1 in terms of turnover and market share.
Innovation and new product development are always our key policies. Our R&D laboratory is built subject to the national standards, capable of all tests required by CE, GB, and UL criteria. Our R&D team comprises of the first national postdoctoral scientific and research station in boiler industry and the only thermal engineering R&D center of Guagndong province. In 2005, we were entrusted by the Government with drafting the National Standards for Gas Domestic Boilers.
Customer satisfaction is the ultimate goal we in pursuit. We, the Devotion people, are devoted to supply you the most reliable, quality products and best services. We remain open to any business opportunities with customers from all over the world.
