The old method of residential heating and cooling involved burning expensive oil or gas in a furnace to heat air sent through ducts. However, much of the heat went up the chimney rather than heating the home. A new method called geothermal heating and cooling uses heat pumps and underground pipes (closed loops) to extract stable 55 degree energy from the earth to both heat and cool homes efficiently. Geothermal systems provide heating and cooling for around 25% of the cost of fossil fuels and require little maintenance over their 30 year lifespan.
2. The old method of Residential
Heating and Cooling
Most homes have a separate heating system which burns
expensive oil or gas in a furnace.
3. Residential Heating and Cooling
The furnace heats air and sends it through the
home via air ducts to each room.
Some homes use boilers to send hot water to radiators.
4. A lot of money goes up the
chimney…
Unfortunately, especially with
furnaces and boilers built before
2000, much of the heat goes up
the chimney instead of heating
your home.
5. Poor efficiency = Wasted money
In fact, according to “Consumer Reports”, most gas
furnaces built in the 70s had an Annual Fuel
Utilization Efficiency around 65%.
And most oil burners were even worse.
6. Fossil fuels seem more expensive
every day
As energy costs have gone up, the industry has been
trying to find ways to keep your home comfortable for
less cost.
7. Free energy from the earth
Instead of burning fossil fuels, some companies have
solved the problem by taking free energy from the
ground to keep you comfortable.
The process is called GEOTHERMAL heating and
cooling.
8. Heat Pumps
The heart of a geothermal system
is the HEAT PUMP which replaces
all the components of your old
heating and central air conditioning
systems
We recommend Next Energy
geothermal heat pump systems
9. Free energy from the earth
Free energy (temperature) from the earth is brought to
a Heat Pump and used to warm and cool your home
completely replacing the expensive oil or gas you
currently use.

10. Free energy from the earth
A couple feet down, the ground stays approximately 55
degrees all year long. And 55 degrees is warm in the
Winter and cool in the Summer.
It is that temperature differential which makes a heat
pump work.
11. Geothermal Energy Efficiency
• With geothermal, you only pay for roughly 25% of your home’s
heating and cooling costs, the rest comes FREE from your backyard
12. Heat Pump Efficiency
A conventional furnace is rated on how efficiently it uses fuel.
Furnaces from the 70s were typically around 65% efficient. An
average furnace today is 80% while a high efficiency unit may be
90% efficient.
That means for every $1 of fuel you put in, you get 80 or 90 cents of
heat.
Heat Pumps are measured in COP – Coefficient Of Performance
which is a measure of how many BTU’s of heat are generated from
the electric energy used.
A Next Energy Heat Pump, connected to a geothermal field, can
offer a minimum COP of 4.0 which translates to 400% efficiency.
Because you use free energy from the earth, that means for every $1
of fuel (electricity) you use, you get $4.00 worth of heat.
13. Heat Pump Efficiency
SEER stands for Seasonal Energy Efficiency Rating , it is
used to describe the energy efficiency of air conditioners
by blending the BTU output of the air conditioner with
the cost of energy used per hour.
14. .
Average SEER ratings for air conditioners from the 70s would
have been 6 – 8.
Efficiency ratings today start at the Federal minimum of 13
with mid range units at 14.5 to 17 SEER .
Some high efficiency air conditioners offer 23 SEER ratings.
Unfortunately, as the weather gets hotter, conventional A/C
efficiency can decrease by over 20% in efficiency!
Next Energy Geothermal systems range from 25 - 40 SEER
ratings and their efficiency remains stable, even on the
hottest days!
15. Free Central Air Conditioning
In addition to saying “Good Bye” to your oil man,
another big benefit is that while you are purchasing an
extremely efficient heating system for your home you are
also getting a properly sized central air conditioning
system, virtually for free!
16. Free Central Air Conditioning with a
Geothermal Heat Pump System
Because a heat pump uses refrigerant to change the
temperature of the air just like the refrigerant in your
refrigerator which is actually a heat pump operating in the
cooling mode.
17. All you feel is comfort
So, go ahead, set the thermostat to be comfortable.
No more wearing sweaters in the Winter because it is
too expensive to keep the house at a comfortable
temperature – sweaters should be a fashion statement!
18. All you feel is comfort
The heat pump does the rest by simply reversing the
direction the refrigerant flows in the system
The refrigerant works as well at warming your home as it
does cooling your home.
19. Heat pumps have been around a
long time since 1857 when
Heat pumps have been in existence
Peter von Rittinger built the first one
You have probably used several of them and not known
they were heat pumps…
Refrigerator Dehumidifier Air Conditioners
20. A refrigerator is a heat pump
Coil #2
A refrigerator is a heat pump
operating in the cooling mode
• There are two heat exchange
coils and a compressor which
moves refrigerant between
the two coils Condenser
Coil # 1
21. The theory of “removing heat”
A refrigerator feels cool on the inside because heat from
the inside has been absorbed by refrigerant in the
cooling coil.
That refrigerant constantly circulates,
carrying the heat it just picked up to
another coil on the back where a fan
blows air across it, taking the heat away.
22. The theory of “removing heat”
Instead of using outside air which is cold in the Winter
and hot in the Summer, a Geothermal system uses the
constant temperature in the earth to warm your home in
the Winter and cool it in the Summer.
23. Methods of extracting energy
from the earth
To get energy from the earth, you can drill
a well, pump water up to the heat pump
and drop it back down into the ground
- that method is called an open loop.
Or, insert pipes into borings and
run fluid thru the pipes. The fluid is
constantly circulated, exchanging
energy between the earth and the
heat exchanger, that is a closed loop
system.
24. Pros and cons of open loop
systems
Open loop system
Pros
Generally cheaper to install
Only needs two or three wells.
Cons
Dumps water back into aquifer or soil after use
Requires high HP pump = expensive to run
Should treat water entering system
Pump submerged 100+ feet with relatively shorter life expectancy
Needs well drilling truck to repair or replace pump with associated property damage
Requires DEC permit and report if failure occurs
Unknown environmental impact
25. Pros and cons of
closed loop systems
Closed Loop
Pros
Warranted 30 years
Small, low HP pump at heat pump = low cost of operation
Pump can be changed in ½ hour if needed
No environmental impact
Cons
Drilling cost can be higher
26. So, how can 50 degree earth
temperatures replace 1600 degree
flames in a furnace
A furnace uses flames, created from burning oil or gas, to
heat air.
When you stop the flames, the area cools quickly to
ambient temperature and more flames are called for,
which means more oil or gas is used.
And don’t forget, much of the heat
from those flames goes up the chimney.
27. So, how can 50 degree earth
temperature replace 1600 degree
flames in a furnace
A geothermal system absorbs ground temperature and carries it to
a coil in the heat pump.
The refrigerant in the coil either boils or turns cold, depending on
which way the refrigerant is traveling in the loop.
28. So, how can 50 degree earth
temperature replace 1600 degree
flames in a furnace
That heat (or cold) is then transferred at the second coil
in the heat pump which warms, or cools air which then
delivered to every room in your home.
Finally, the hot air in your home in Summer, or cold air
in your home in Winter, transfers it’s energy back to the
refrigerant which carries it back to the heat pump coil
and back to the earth.
29. How about maintenance costs?
Remember the refrigerator example?
How many times in the last 10 years have you needed
someone to come fix it, clean it, tune it up or get it going?
Now think of your furnace.
How many times in the last 10 years have you needed
someone to come fix it, clean it, tune it up or get it going?
