Energy EfficientHeating and Cooling Systems

For Today

Geothermal Heating, Cooing

And Hot Water Systems

Presentation Goals

Familiarize you with the Today’s Heating Equipment Choices.Help you evaluate and decide the best Heating System Design for your home.Show you why Geothermal Systems should be your Choice.

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

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

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.

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.

Typical installation time…

Other than the normal times required to do the duct work and electrical wiring…

- One day to do set the indoor unit- One to Two days to install the Earth Loop
