The nation's heating infrastructure is little better. By 2002, only 40 percent of China's total housing had heating, with electric seeming the most common mode. Hydronic heating has started to make significant inroads into the market, and was prominent among the displays at ISH China 2006, held in Beijing March 14-17.
The sixth version of ISH China featured 293 exhibitors from 19 countries and regions, and 15,307 visitors streaming in from 45 countries. Among them were American companies A.O. Smith, Honeywell, Rheem, SPX and Weil-McLain, along with standard and code agencies NSF and IAPMO. Canada's tekmar also was present.
