Forced air only compounds the problem of uneven heating by operating cyclically—that is, by stopping and starting over and over. If you've ever set foot in a home heated by forced air, you know the routine. When the system kicks on, warm air roars into the space—for a while—then suddenly halts. Later, once the home has cooled to a threshold point, the heat starts up again. The result? Intermittent, dramatic temperature swings that send the homeowner back to the thermostat again and again. One of the great appeals of radiant heating is that it operates continuously—and silently—delivering comfort that doesn't come and go, but remains cost-effectively consistent.
