Geothermal Energy

Solaya entered the renewable energy market with geothermal HVAC projects. Now IGHPA certified in geothermal HVAC installation, Solaya has become an expert in the New England region.

Soil temperatures in the upper 10ft of the earth’s crust remain at a relatively constant 50 to 60 degrees Fahrenheit all year. For most areas, therefore, soil temperatures are warmer than air temperatures in the winter and cooler in the summer. Geothermal heat pumps use water in pipes to absorb heat from the ground and transfer it to the building in the winter and vice versa in the summer. This heat transfer reduces energy demand in HVAC systems significantly enough that the U.S Environmental Protection Agency considers geothermal pumps the most energy efficient, cleanest, and most cost effective systems for temperature control.

While geothermal pump systems can reduce energy demands, Geothermal Power Plants can generate electricity with little pollution and environmental impact.

Three Types of Geothermal Power Plants

  • Dry Steam Plants - Steam is piped directly from a geothermal reservoir to turbine generator turbines.
  • Flash Steam Plants - High pressure hot water is brought to the surface where it becomes steam and drives generator turbines. When the steam condenses to water, it is injected back into the ground where the earth reheats it.
  • Binary Power Plants - The hot water from the earth heats another liquid that boils and drives a generator turbine.
