Hydronic radiant floor (HRF) heating is not a new concept. But over the last few decades, due to advances in technology, it has been rapidly growing in popularity. This growth is measured by the millions of feet of tubing sold each year in North America.
The most explosive growth has been in the custom residential building market. Homeowners and builders have come to realize the comfort and energy efficiency that HRF systems can provide, and are quite often willing to pay the higher installation costs compared to forced-air heating to obtain these benefits.
