Geothermal

How it works.

Implementation

Geothermal technology is very much the unsung hero when it comes to renewable energy; what about a direct replacement for oil and gas?

Geothermal is a geoexchange system. It uses the constant temperature of the earth to mitigate the climate above ground. Earth is a vast solar collector. About 46% of the suns solar energy maintains a nearly constant temperature throughout the year just below ground. Geothermal heat pumps transfer underground heat into buildings to provide heating during the winter and they transfer heat from buildings into the ground to provide cooling in the summer months.

To better understand we need to make an apples to apples comparison.

Let’s say I have an average 1500 square foot house that was built in the last 25 years. It’s time to replace my old oil/gas boiler and A/C unit with a new geothermal system that combines the two systems in one.  First, I would need 4 holes drilled into the ground for the heat exchange pipe at a depth of 200ft. These pipes are then brought into my basement where my existing unit was. After swapping out the old units with clean, sustainable geothermal units, Mother Nature will take over from here. A temperature differential is created between the ground and the house in all seasons, thus creating heat in the winter, cool air in the summer and taking care of over 60% of your hot water needs!

Why an E2sys Closed Loop Geothermal System?

There is a slightly higher initial cost with closed loop systems due to more wells that have to be drilled for the heat exchanger. The open loop is definitely a less costly option in the short term, in the long term this has proved to be a costly mistake with wells to be re-drilled and heat exchangers in units to be de-scaled thus reducing efficiency.

Eastern Energy systems could do an open loop for you however; our company is here for the long term and not for a quick profit. We really want our clients to spend their money on a system that is maintenance free and works for 50+ years. One important consideration is that the high density polyethylene ground heat exchanger will operate for nearly 50+ years so in 25 years you may change your geothermal unit but not the heat exchanger in the ground.
