energy_efficientUsing a wide array of compressor inverter technology with LG VRF systems or Innovent’s AHU solutions. Geothermal opportunities coupled with Water Furnace WSHPs. Dectron’s ability to heat pool water by recovering energy from the dehumidification cycle.

Stand Alone Systems

Currently the two most efficient stand alone systems in the industry are geothermal water source heat pumps (WSHPs) and variable refrigerant flow (VRF) systems.  RJI represents industry leaders in both of those market segments with Water Furnace’s water source heat pumps and LG’s variable refrigerant flow systems.

Variable Refrigerant Flow (VRF) is a technology introduced to minimize efficiency losses found in conventional HVAC systems thus providing sustainable energy benefits. A VRF system utilizes the flow of refrigerant to provide heating and cooling throughout a building.  With the addition of a heat recovery box a single system can provide simultaneous heating and cooling for optimal occupant comfort.





WFI       Water Source Heat Pumps

Reduce your carbon footprint and utility bills at the same time. Water Furnace geothermal systems use the free, renewable energy found in the Earth to save up to 70% on heating, cooling, and hot water costs.

Water Furnace’s high efficiency models are guaranteed to increase LEED points for your building by including components like MERV 13 filters, IAQ management, and System Controls, as many as 15 LEED points can be awarded
