In this episode Build Show expert and master plumber Eric Aune demonstrates radiant heated slab installation in a shop. He explains the step-by-step process of laying out and securing half-inch tubing in eight evenly spaced loops, each under 300 feet to maintain pump efficiency. He covers essential details such as manifold connections, conduit protection at concrete entry points, and precise nine-inch spacing for even heat distribution, with tighter spacing at perimeters to offset heat loss. The installation concludes with a 60 psi air pressure test required by local inspection standards. Eric emphasizes safety, neat workmanship, and proper preparation for the concrete pour, including rebar grid placement above the tubing. This clear, practical guide showcases best practices for professionals and DIY enthusiasts alike, making it an ideal resource for understanding efficient radiant floor heating installation in garages or workshop environments.
