Geothermal Heating and Cooling Book; Real Cheap, Really Good!

Posted by Jay Egg

IN MY EFFORTS TO GET UNDERSTANDABLE and easy to read information into the hands of consumers about green technologies, it is refreshing to see an affordable book come out on geothermal heating and cooling technologies. The new book, “Geo Power” is just that; affordable, understandable, and richly illustrated.

Renwable Energy; YES!   Metric Marvels; Not so much...

OLD HABITS DIE-HARD. Many of us can remember when the public school system curriculum began metric instruction.  In 1970, I was a student at Skyline Elementary in Barstow, CA.  I distinctly remember Mrs. Sims sharing the Metric System with us in 1st grade, stating that by the time we were in high school, the Old-English measurements of miles, pounds, and pints would be all but history. What happened?

I also remember the promise of electric cars, on-line shopping (they called it “TV shopping”) and solar energy; all by the time we were in high school. I’m pleased to see that even though it’s taken a bit longer (45 years later), most of those energy efficiency initiatives have become a reality. I don’t know what to say about the metric system...

One of the forms of renewable energy that is enjoying widespread acceptance (unlike the “Metric Marvels”) is geothermal; so much so that we are have remarkable interest at elementary and upper-grade level studies.  I get increasing numbers of requests from kids all over the country for information that they can use in reports and essays on geothermal heat pump (GHP) technologies.  That’s great news.

Geothermal HVAC and the “Negatherm” Factor

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:

Get Your Spring-Time Energy Savings with Geothermal Pool Heating

Posted by Jay Egg

SPRING IS HERE, and the cooling season is quickly approaching. Pools that have been out of commission for the 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.
