Why don’t my floors feel warm?

Figure 2b Strategic placement of radiant panel I used the design approach of not covering the entire floor area with tubing when designing the floor heating system in my own house in 1979.  Figure 2a and Figure 2b show images of the floor heating panel in our dining area. The panel was constructed using 3/8-inch copper tubing because PEX tubing was not available in North America at the time. We installed the radiant panel under the eventual location of the dining table, right where our feet rest on the floor. It feels great on a cold winter morning.
