Energy Efficient Heating 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 foundation The 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.

Your Heating System Choices

Conventional Designs

Hydronic Systems



Hot Water or Steam

* Provides: - Excellent Comfort, - Quiet,

Forced Air Systems *Does not provide

- Air Conditioning - Air Cleaning (no filters) 

Ducted System

* Provides: - Good Comfort - Very Flexible design - Central Air Conditioning - Filtered Indoor Air Higher Initial Installed cost Extra cost to add Central Air Equipment Efficiency Ranges: Low to Med - High Lowest Initial Installed cost Reasonable Cost to add Central Air Equipment Efficiency Range: Low to Med - High

Appliances 11% Lighting 3% Hot Water 22% Heating & A.C. 64%

Heating System Choices… Geothermal Designs Hydronic

 Hot Water System        Excellent Choice for Radiant Floor Heating Can be used to provide Chilled Water for Cooling Applications Can be used to provide Domestic Hot Water Highest Efficiency Lowest Operating cost Greater Safety Higher First Cost to purchase

Forced Air System

 Ducted System         Good Comfort Flexible Design Filters the Indoor Air Many Accessories are available Highest Efficiency Lowest Operating cost Greater Safety Higher First Cost to purchase

Geothermal Systems use … T he 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

Geothermal System

Geothermal – Renewable Energy 1 unit of Energy Purchased 3 Additional Units Absorbed from the Earth 4 units of Energy output Your getting up to 400% Efficiencies !

Geothermal Designs  Closed Loop Utilizes continuous loop plastic pipes   Horizontal Trenched Designs Vertical Bore/Drilled Designs  Pond Designs  A Water/Ground Source Heat Pump Utilizes Ground Water – open loop/well water direct use from surface water

Closed Loop Designs

 Benefits  Lower System Maintenance  No Addition Water Requirements  Hurdle  Higher Initial Purchase Cost  More Land Required

Geothermal Unit Installation

Ground Water Geothermal Unit Installation Ground Water Typical Application

Vertical Loop One Pair Two Pair When Loops are shallower than one ton per loop Series/Parallel One Pair

Horizontal Loop 2 ft Tw o- Pipe 2 ft Four -Pipe Back-Hoe Loops 2 ft Six-Pipe Tw o- Pipe Four -Pipe Trenched Loops Extended Slinky

Pond/Lake Loop Concrete Blocks for weight Nylon Cable Ties to secure blocks 4 ft between coils 300 ft coil per ton separated by scrap pipe Traditional Coiled Pond Loop - Southern Climates Reverse Return Header 3 foot separation Heavy Duty Plastic Safety matting Nylon Cable Ties to secure Netting and bricks 8-10 Bricks for weight 300 ft slinky coil per ton High Efficiency Slinky/Matt Pond Loop - Northern Climates

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.

Geothermal allows you to usually meet the Model Energy Codes Without changing the construction process

Benefits of Purchasing Energy efficient products like Geothermal List Price Monthly Mortgage Monthly Utilities: Tax Savings:

Total Monthly Cost: Positive Cash Flow: Standard Home

$160,000 $1,323 $142 $0 $1,465 $0

Energy Efficient Home

$163,000 $1,348 $100 ($3) $1,445 $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

Retrofit Homes… The Add-on Geothermal System General Installation Add On Coil TXV ‘IN’ toward outdoor condensing unit Paradigm Condensing Unit Power Disconnects Insulated line set with UV Paint Add-On ‘A’ Coil Air Temperature Limit Switch Fossil Furnace Return Plenum Air Pad Low Voltage Wiring PVC Condensate with vented trap
