The radiant heating industry continues to grow, according to statistics gathered by the Radiant Panel Association. In 1999, 138.7 million feet of radiant tubing was sold in North America.
The RPA surveyed 17 tubing manufacturers about the number of feet of tubing sold. Of those surveyed, eight (or 77 percent of the total represented tube sales in North America) responded. The 138.7 million figure shows an almost 14 percent increase over the 1998 figures. Though the figures show growth, there has been a decline in the growth rate shown in previous years.
