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.

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.

Geothermal Heating and Cooling Systems; Great for the Environment!

Geothermal Heating and Cooling Systems; Great for the Environment!

An earth coupled HVAC system is packed with "Earth Friendly" benefits, especially when compared with any other types of air-conditioning and heating systems. As heating and cooling systems go, a ground sourced system comes closest to the way Mother Nature would heat and cool your home if given the opportunity.

 

That's because with geothermal, your house becomes coupled with the Earth beneath, sharing that temperature with your environmentally friendly geothermal heat pump, similar to the way the roots of trees share nutrients with their branches and leaves. Take a look at some of the environmental benefits you can enjoy with geothermal system:

Extreme Spring-Time Energy Savings with Geothermal Pool Heating

Posted by Jay Egg

Apr 2, 2014 12:53:00 PM

Spring is here, and the cooling season is quickly approaching. Pools that have been out of commission after our very cold winter are likely to stay that way unless we turn the heat on.  That can get expensive.

Stop for a moment and think of how many blow dryers, computers, cooking appliances, lights and people there are in your home that add to the cooling load.  These are all a potential source of energy that can provide domestic hot water and be used to heat spas and pools. With standard air source heat pumps or air conditioners, the heat generated inside your home typically goes out the return air ductwork and ultimately is exhausted through outside air exchange.

After 5 Years of Stimulus, Home Energy Efficiency Emerges as Job One

Posted by Jay Egg

Mar 3, 2014 10:57:37 AM

Reviewing the five-year report to Congress on the economic impact of the American Recovery and Reinvestment Act, and resulting news reports and sound bites, I began to see through the rhetoric and partisanship.

Regardless of opinions, the fact is that there have been millions of jobs created in the green energy sector, and green building has arrived as the norm rather than the exception. But that is a broad brushstroke; and as the sun begins to set on the US stimulus package (2009-2016), the important thing is to look at what we have gained in the US, and where we're headed.
