Bromic Heat Deflector - 300 SeriesBy absorbing heat that would otherwise escape vertically, Bromic’s Gas Heat Deflectors significantly reduce the clearance needed between the top of a heater and the surface above from 1100mm/3’ to 350mm/14”. Our stainless steel deflectors are unique in their dual layer construction, which uses the rigid top layer for reinforcement while reducing radiation of heat absorbed by the bottom layer.
