When using bamboo flooring over radiant heat, it is best to set the temperature and leave it at that temperature. Bamboo flooring will naturally withstand temperature changes(it’s one of the many advantages of bamboo flooring), however, it performs best when radiant heat is set to a constant temperature without changing more than a few degrees per hour. Also, never let the "floor temperature" for the radiant heating system exceed the maximum temperature identified by the flooring manufacturer.
