Ground Source Heat Pumps offer great benefits:

  • Simultaneously heat & cool different parts of the same building
  • Very quiet--users do not know when the system is operating
  • Can be set up in multiple zones, with each zone having an individual room control
  • Greater freedoms in building design due to 50-80% less mechanical room space
  • No outside equipment to hide, eliminating vandalism and roof top units
  • Pipes have 50-year life expectancy
  • All electric, which eliminates multiple utility services
  • Boiler and chiller maintenance
  • Ground heat exchanger is maintenance free and will last 50+ years

Ground Source Heat Pumps offer great savings:

  • Very competitive on initial costs and lower lifecycle costs than most HVAC systems.
  • Savings of 25-50% on energy consumption
  • Lower peak demand, lowering your operating costs
  • Water heated with waste heat from air conditioning at no cost in the summer and at substantial savings in the winter
  • Some utilities offer rebates or incentives to their customers who purchase GSHPs.

Ground Source Heat Pumps are environmentally friendly:

  • Conserve natural resources by providing efficient climate control and thus lowering emissions
  • Minimize ozone layer destruction by using sealed refrigeration systems, which seldom or never have to be recharged
  • Use underground loops to transfer heat, with no external venting and no air pollution
  • Very energy efficient, with the earth providing over 70% of the energy required to heat and cool
