RN&M IS A LEADER IN THE DESIGN AND IMPLEMENTATION OF GEOTHERMAL HEAT PUMP TECHNOLOGY.
This technology has been very popular residentially for many years, however, we apply it on a large scale. Central plant equipment can be eliminated by utilizing the earth, as a heat sink. The system of vertical bores or “well field” can be located under sports fields or parking lots. The well field is a closed loop; so it is environmentally friendly (no groundwater contamination). Water is pumped from the building, out to the well field thru closed piping (where heat is either dissipated or absorbed); and the water then flows thru the water-cooled heat pump units in the building and back out to the well field. The heat pump units in the building provide heating and cooling – much like the heat pump in a typical home.

THE ADVANTAGES OF GROUND SOURCE HEAT PUMP SYSTEMS ARE:
- Very efficient (35% or more less energy consumption than typical systems)
- Quick payback (as low as 4 years in some cases)
- Less equipment to maintain
- Low sophistication level of equipment and controls (user friendly)
- Long equipment life (water-cooled compressors are durable)
- No outdoor equipment (no noise, no “ugly” equipment, no outdoor maintenance)
- Very low net carbon footprint and emissions.
