Jay Egg

Jay's passion for geothermal air-conditioning and heating started during a repair to his own home air-conditioning system 1989. Frustrated by the extreme tropical climate which had added to the premature failure of his air-conditioning system, he modified his home air conditioner to become a ground water-cooled system. Jay founded EggGeothermal in 1990 to provide geothermal HVAC systems. As a result of the American Recovery and Reinvestment Act of 2009, EggGeothermal entered into a new age of acceptance. Jay currently focuses his professional efforts on geothermal consulting, writing, and speaking engagements. Among his clients are federal, state and local governments, developers, associations, and private entities.

The "Geothermal HVAC Dream-Team" is in Your Own Home Town

A geothermal team consists of all the parts to make a geothermal heating and cooling project come to fruition; and they’re likely right in your local area.  You may want to install a geothermal-solar system in your home, or have it deigned for a whole community, and the parts will be much the same.  Like a library full of books, the knowledge is there.  What makes knowledge powerful is when it is assimilated for a great purpose like earth coupled HVAC.

Choosing A Window AC Costs More Than You Think

Don't let the initial low cost of an off-the-shelf window-sized air conditioner fool you. Before long, you'll be paying far more for that cool air than you would with an alternative such as geothermal.

 That back bedroom is just too hot! Maybe “they” didn't run a big enough duct, or you’ve never had AC there.

Cold Comfort. Window-sized air conditioners may seem like a good deal, but they're woefully poor users of energy.It doesn’t matter if you’re in a four room apartment or a single family home, the weather outside is hot.

The first stop for most people is the home improvement store, Amazon, or whatever else is available in a moment of desperation. We purchase a $200 window or "through-the-wall" air-conditioning unit, and pay tremendously high energy bills for a woefully inefficient product. Let's look at some of the real and intangible factors with regard to the cost of installing a window air conditioner, some of which may not have come to mind.

Geothermal Makes Celestia Kitchen of the Future Even More Efficient

IN THE HOME OF THE FUTURE, appliances will be linked like hardware on a computer.  Just like a new wireless keyboard, printer or touch screen monitor, you need only place the new appliance into service and it will communicate on a machine to machine basis (M2M), providing useful data for energy and performance optimization. But electronic communication is one part of the equation.  There is also the concept of “Thermal Communication”.

The household appliances in our “Celestia Home of the Future” will prompt, "Do you really want to start the washing machine now, while the shower is on and the dishwasher is running? Please allow me [the smart M2M system] to start this for you later, when energy and water consumption can be optimized, saving 1.3 kWh of peak load energy consumption."  This simple logic and communication between machines, homes and communities will defer infrastructure costs for building of power plants that could be averted.

Storm Proofing; Come Inside and Out of the Weather

With geothermal heating and cooling systems, you can weather the storm and rest easy. The equipment is all inside, reducing premature wear and tear.  There is no equipment to encumber your landscaping or to interfere with children at play, and noise pollution is eliminated.  

On March 13, 1993, Floridians were awakened by what sounded like a passenger jet engine outside their homes.  It turned out to be 70+MPH winds from the fury of Florida’s no-name “Storm of the Century.”

Property damage was significant, and many were left without air conditioning when their outdoor condensers were destroyed by wind and water.  Clients with geothermal heat pumps fared better, sustaining no damage due to the "all-indoor" nature of a geothermal heating and cooling system.

Geothermal HVAC and the “Negatherm” Factor

Posted by Jay Egg

May 15, 2014 12:59:00 PM

 

In our first geothermal book, Geothermal HVAC, Green Heating and Cooling (McGraw-Hill Professional, 2010, p16), Brian Clark Howard and I shared a dialogue from an article wherein a commenter said that switching from a gas furnace to ground sourced heating is increasing the burning of fossil fuels, because the power plant producing the electrical power is probably burning coal, natural gas or other fossil fuels.  The argument seems valid until you understand what we call the “Negatherm Factor”.

 “Negatherm” is a term that was coined to refer to energy that would or could have been used from fossil fuel consumption, but was never used.  “Nega”, root of “negative”, meaning unused, and “Therm”  a unit of energy equal to 100,000 BTU’s, usually measures the combustion of fossil fuels for heating a home or business.  When heating from an appliance using electricity, we use “kilo-watt-hours” (kWh).  Electricity comes from many different fuel sources including hydroelectric, solar, wind, hot rock geothermal, nuclear, natural gas, coal, and diesel to name a few.  We are certainly seeing an increase in the renewable sources, the first four in particular.
