Your building Dreams…Start with a good foundationThe Mechanical Systems in your new home are some of
the most important.
Look closely at the Heating,Cooling and Water Heating systems…
These are the Three (3) largest energy consumers
in your utility bill!

Heating and Cooling System Sizing
Based upon the Construction Material R-values, Air Infiltration, and Local Weather Data.
Good Heating Contractors should calculate the home’s Heating and Cooling requirements - room by room. This is called a “Manual J” calculation
Example Total Building - 2,000 sq ft Heat Loss: 74,000 BTH/HR - Heating Season Heat Gain: 34,000 BTU/HR - Cooling Season
![Page 5: Energy Efficient Heating and Cooling Systems For Today Geothermal Heating, Cooing And Hot Water Systems.](https://reader030.fdocuments.in/reader030/viewer/2022033100/56649cd55503460f9499cbda/html5/thumbnails/5.jpg)
Heating Systems are sized...
By using the “Manual J” calculation
The Homes square feet is not a good method to select equipment by.

Geothermal Systems use …The Basic principle of refrigeration:
We Simply transfer Heat Energy from areas of “Hot or Cold” with the assistance of a Refrigeration System…
Coupled with the extra energy efficiency of a liquid source heat pump

Antifreeze – Why?
Protects the equipment in case of Freezing conditions (power failures)
Enhances the Energy Transfer ratio between the earth and fluid in the piping
![Page 23: Energy Efficient Heating and Cooling Systems For Today Geothermal Heating, Cooing And Hot Water Systems.](https://reader030.fdocuments.in/reader030/viewer/2022033100/56649cd55503460f9499cbda/html5/thumbnails/23.jpg)
Anti Freeze Fluids for Closed Loops
Methanol/Ethanol – Alcohol Based- Least expensive and best performance
Propylene Glycol – Food Grade Based
- Non-toxic and lower heat transfer ratio
- More expensive, some area codes require

How much will it Save?
Up to 60% over conventional systems The energy savings can pay for itself
within 2- 6 years typically, depending upon your fuel, and installation costs You’ll Save enough money every month to
cover the additional loan charges in a New Home Mortgage Loan by lowering your utility bills! It virtually pays for
itself.

Geothermal allows you to usually meet the Model
Energy CodesWithout changing the construction process
![Page 27: Energy Efficient Heating and Cooling Systems For Today Geothermal Heating, Cooing And Hot Water Systems.](https://reader030.fdocuments.in/reader030/viewer/2022033100/56649cd55503460f9499cbda/html5/thumbnails/27.jpg)
Benefits of Purchasing Energy efficient products like Geothermal
Standard Home Energy Efficient HomeList Price $160,000 $163,000Monthly Mortgage $1,323 $1,348Monthly Utilities: $142 $100Tax Savings: $0 ($3)Total Monthly Cost: $1,465 $1,445Positive Cash Flow: $0 $20
*As you can see, by reducing the amount of your monthly utility bills, the geothermal system allows you to put more money towards your overall loan amount. You are then able to purchase more Home for the same
amount of money each month.
