It depends on the type of bamboo flooring being installed. Because bamboo is technically a grass, some products made from it can be sensitive to heat and/or direct sunlight.
Check with the manufacturer of the bamboo flooring to find out what its temperature limitations are. Remember that while the surface of a floor with radiant heat typically does not exceed 85 °F, the temperature of the bottom of the flooring can get up to 110 °F.
