A common question many homeowners ask when considering radiant floor heating is exactly how warm the floors should get. The maximum temperature that a floor will reach before it becomes uncomfortable is 87.5 degrees Fahrenheit. Any higher than this, then the floors will seem hot to the touch. Any lower, and they might not be generating enough heat. Fortunately, this desired temperature can be reached no matter what sized PEX tubing you choose.
