What Is Radiant Floor Heating?
Radiant floor heating works by circulating warm water through tubing installed beneath your flooring. Unlike forced air, it doesn’t stir up dust, make noise, or leave you with cold spots. It’s cleaner, quieter, and far more efficient—especially in colder Eastern Washington winters.
