Water Well Drilling FAQ

Water Well Drilling FAQ

A well is a hole that is drilled deep into the ground. The top portion of the well is lined with casing to prevent collapse and stop any contaminants from entering the water supply. A pump sits at the bottom of the well to move water up through pipes to a distribution line. A well cap is placed at the very top of the well to provide sanitary protection and safety.

Call a professional. Well-technicians are certified in water well drilling, which means they are licensed by the state. Any construction or repairs needed should be done by a professional.

What factors determine the cost of a new well? The largest factor in determining the cost of a new well is the well depth. This can be tricky, because we will not know the actual well depth of a new well until we drill it. We rely on information on other wells in the area to estimate the depth of a new well.

Geothermal FAQ's

Geothermal heating and cooling systems use the earth’s natural thermal energy to provide efficient and sustainable heating and cooling for residential and commercial buildings. By utilizing a series of underground pipes filled with a fluid or refrigerant, the systems are able to transfer heat to or from the ground, depending on the season. This process provides a reliable and low-maintenance solution for temperature control.

Geothermal heating and cooling systems provide many benefits to homeowners and commercial property owners beyond simply providing efficient and sustainable temperature control. Geothermal systems have lower energy costs, lower maintenance costs, and a higher year-round comfort level than conventional systems.

The first step in installing a geothermal heating and cooling system is to contact Connecticut Wells to be put in touch with a qualified HVAC contractor in your area. Your HVAC contractor will perform a heat loss calculation that takes into account your home’s efficiency to determine the number of wells that you need for the system. Connecticut Wells will help install a series of underground pipes filled with a fluid or refrigerant to transfer heat to or from the ground, depending on the season.

While the initial investment in a geothermal system may be higher than in a traditional furnace or air conditioning unit, the long-term savings in energy costs and maintenance costs make them a cost-effective solution. Owners of geothermal systems typically enjoy utility bills that are 25-70% lower than with conventional systems, and there are lower maintenance costs. Additionally, the National Association of Realtors Appraisal Journal estimates that a home’s value increases by $10-25 for every $1 reduction in the annual utility bill with a geothermal system.

Geothermal systems can be very efficient, providing 70% renewable energy from the ground and using electrical energy to concentrate and transport heat. With more efficient models now available, the COP (coefficient of performance) of a geothermal system can return 4 or 5 units of energy back into a home for every one unit of energy put in. These systems are rated highly for efficiency and have been winning market share among new and retrofit residences worldwide due to their low environmental impact and ease of use.
