For those that may be interested in geothermal you may find a recent interview with Jay Egg of interest. The podcast can be found at this geothermal link. Jay describes how he entered the geothermal hvac profession, tax credits available, the future of the industry, and the installation process. His book, Geothermal HVAC: Green Heating and Cooling, is also described and explained.

Anyone who may be considering installing a geothermal hvac unit or going into the geothermal field would find this interview helpful. Enjoy!

Our New Book

A little over a year ago Jay Egg, president and owner of Egg Systems, was contact by McGraw-Hill Publishing company and asked to write a book about Geothermal HVAC. That book was published several months ago and since then it has quickly gained popularity as an informative and practical guide to geothermal technology.

Geothermal HVAC: Green Heating and Cooling covers the fast-growing field of geothermal air conditioning and heating technology and all of its peripherals, in both the commercial and residential sectors. You’ll get details on the vast array of choices currently available on the market, so you can take advantage of this emerging money- and energy-saving technology. The book is co-written by Jay Egg, who has 20 years of direct experience and accreditation in providing geothermal systems, and Brian Clark Howard, a Web editor, author, and environmental blogger. You’ll learn what type of systems will likely work in a particular area, as well as what pricing to expect for a particular efficiency and quality. Geothermal HVAC: Green Heating and Cooling:

  • Explains the science and principles of heat transfer, convection, and infrared
  • Identifies how to pair the best systems for each application and budget
  • Lists market values for systems based on varying options and conditions
  • Includes information on all the domestic and international tax rebates and stimulus packages available for implementing geothermal.
  • Contains coupons for discounts on geothermal products and services
The book can be purchased through Amazon: Geothermal HVAC Book.

Geothermal Training and Certification

Many HVAC contractors have contacted us over the past few years wondering about training and certification. Currently there is not an official certification program for the industry. We have provided many HVAC business owners with training and education on geothermal HVAC installation. These individuals have been very grateful as they've noticed others view them as leaders in their field with the added service.

Geothermal Mechanical Engineering

Egg Geothermal has an expert staff of Mechanical Engineers (Heating, Ventilation, and Air Conditioning) for the design of systems that cool, heat, purify, circulate, humidify, and dehumidify air. We design climate control systems that are used in a wide range of indoor areas, from Olympic sized swimming pool heating and office buildings to homes, to fisheries and aquariums. These systems help people and nature work and live with maximum comfort and safety. Air conditioning also helps machines and other equipment work properly. For instance, the humidity level in a print shop must be controlled so that the paper does not shrink and the ink prints clearly. Also, computer systems need to be kept at a certain temperature and humidity. If a sturgeon (fish) gets too warm, or a community pool gets too cool, we can help...We can even heat your bath water, right to that perfect temperature..the Egg Geothermal way!

Egg Geothermal engineers design the perfect geothermal loop and pump systems to cool, heat, and control your environment, whether it be for your homes, apartment complexes, offices, shopping centers, hospitals, schools, stores, factories, or theaters. Each project area has its own set of challenges that the our engineers are qualified to solve. Our engineers can meet the needs that come with the typical home as well as developing systems for large areas such as glass-enclosed shopping malls.

Egg Geothermal's engineering staff can help you every step of the way to help estimate the costs of labor and supplies, determine building requirements and needs to design the appropriate Geothermal source for air conditioning systems and also supervise the installation, operation, and maintenance of air conditioning systems. If it needs to be heated or cooled, we can help!

"Geothermal is leaving wind, solar in the dust..."

A Study from NYU

"Geothermal is the cheapest source of alternative electricity and shows the fastest improvement per dollar invested, according to a study from NYU."

In a report by Melissa Schilling, professor at New York University at Stern, geothermal was shown to cost less to produce than wind and solar energy. She also notes that geothermal technology is improving at a faster rate despite it being underfunded by the government and investors.

She suggested that although wind and geothermal have similar current costs, "the performance trajectory of wind is already slowing, while geothermal is exponentially increasing." This shows that in the near future geothermal should be the dominant alternative energy source.

Solar, which is commonly thought of as the leader in alternative energy, costs significantly more and lags behind in projected improvement.

Schilling was surprised by the results of the study. She notes, "The findings are very surprising because most people are not paying attention to geothermal. We went into this really rooting for wind and solar, probably because they're the ones you hear about the most, and they're received a lot of investment, particularly solar."

However, her advice to governments and investors was to invest more evenly towards energy technologies. She says, "Solar is so far away from being cost effective, and tremendously far away from being efficient. Right now the bigger and quicker payoff is geothermal."

Geothermal Heat Pumps

One of the greatest benefits to using geothermal energy to heat and cool your home is the savings on your energy bill. A Geothermal Heat Pump (GHP) is one of the most efficient systems available. They have heating efficiencies up to 50-70% higher than other heating systems, and cooling efficiencies up to 20-40% higher than conventional air conditioning units. What does that mean for you? An energy savings of nearly half in the winter and 20% in the summer!

What is geothermal energy, and how does it work?

Geothermal energy is the energy produced by extracting the earth's internal heat. The earth is relatively constant in temperature, making it a natural source to draw energy from. Geothermal heat pumps are electrically powered systems that tap into this energy to provide heating, cooling, and even hot water for homes and businesses.

GHPs can have either a closed loop or an open loop system, and are most commonly installed either vertically or horizontally. In a closed loop system, water or an antifreeze solution circulates through plastic pipes buried deep in the ground. During the winter, the fluid collects heat from the earth and carries it through the system into your home or office. In the summer months, the opposite occurs; the system pulls heat from your home or office carrying it through the system and placing it in the ground. This process also creates free hot water in the summer and a large savings in hot water costs during the winter.

Open loop systems work much in the same way, and the benefits are the same. The only difference is these systems are installed when an adequate supply of water is available.
