Sima Drilling Company has been installing Geothermal boreholes since the 1970's and is Connecticut's trusted geothermal contractor.

Homeowners all over North America have discovered the benefits of using the free energy in their own backyards to provide heating and cooling. Geothermal heating and cooling systems tap into the constant earth temperatures found down below the earth's surface, offering the finest in home comfort systems. This down to earth technology is yours to tap into.

Our experienced crews have installed all types of closed and open Geothermal extraction systems.

The energy is Free, Clean and environmental friendly.

How the Heat Pump Works

Winter Season

The heat pump operates on the principle that heat can be transferred by a cycle of alternating vaporization and condensation, the same cycle used by refrigerators, freezers and air conditioners. When a liquid vaporizes, heat is absorbed, and when a gas condenses, heat is released. By alternately pressurizing and depressurizing a liquid with a very low boiling point (called a refrigerant), the heat pump can absorb heat from a relatively cool medium and transfer it to a warmer one.

Summer Season

The Geothermal wells Connecticut system are a highly efficient and economical year-round space conditioning system for homes in Connecticut. It can save over 50% on heating costs compared with electric resistance heating (e.g. electric furnace), and up to 30% on air conditioning costs, while providing clean, safe comfort year-round.

Even though the ground or water temperature may be a relatively cool 10 C (50 F), the circulating fluid can absorb some heat, and the vapour compression cycle of the heat pump can transfer it to the indoor air.

How it Works

During the connecticut summers, the same fluid is circulated through the loop of piping and the heat pump's heat exchanger, but the heat pump's cycle is reversed. Instead of absorbing heat from the fluid and transferring it to the indoor air, it now absorbs heat from the indoor air and transfers it to the fluid, where it is given off to the ground or ground water. Because of the constant relatively cool temperature of the ground or water, the Geothermal wells Connecticut system is actually more efficient for cooling than the typical air conditioner, which must reject heat to hot outdoor air.
