The Evolution of Two-stage Infra-red Technology
	Research has shown that a typical Canadian commercial, industrial or agricultural building requires the total designed heating capacity for only 10 percent of the heating season. Proven Re-Verber-Ray two-stage technology addresses this issue head-on utilizing "high-fire' for really cold winter days and "low-fire" for typically 90 percent of the heating season. Independent testing has documented the on-going energy savings, improved comfort and extended product life using the proven two-stage technology developed by Brant Radiant Heaters.
Different Design Parameters for Each Component
This facility consists of a riding arena and stable area. Design considerations for the riding arena included: (1) The customer's request for even heat distribution and; (2) Heated only when occupied. Due to the dirt floor, it was evident that primary infra-red created by the infra-red heaters would be the only heat source. The fact that Re-Verber-Ray two-stage technology achieves required comfort levels by simply varying the primary infra-red output made the two-stage HL Series the best design selection.	A pair of Re-Verber-Ray HL 40-75N infra-red heaters suspended in the centre of the stable alleyway ensure additional heat output for wash-down, as well as creating a temperature differential in each stall allowing individual horses to find their own thermal-neutral comfort zone.
The layout of the stable area was typical with the exception of a specific area for wash down and drying, which required additional heat to keep the horses warm when in use. This need for short periods of increased heating capacity in the stable area made Re-Verber-Ray two-stage infra-red heaters the best choice. In addition, placing the heaters in the centre of the stable achieved three key objectives: (1) Primary infra-red heat energy storage in the concrete alleyway for re-radiation as a secondary source of warmth; (2) Creation of a front to back temperature differential in each stall allowing individual horses to find their own thermal-neutral comfort zone and; (3) Ensuring extra heat on demand with the (high-fire) mode for wash-down and drying. In summary, despite different design parameters, two-stage technology was the logical choice for both the riding arena and stable area for a cost-effective heating solution.
