Geothermal Heat for Radiant Floors

  1. 1. Geothermal Heating and Cooling<br />A Smart Feature of <br />Apple Built Homes<br />
  2. 2. The world's supply of fossil fuels <br />IS<br />NOT<br /> LIMITLESS.<br />
  3. 3. Geothermal Energy<br />A Green Alternative?<br />
  4. 4. Green Potential<br />
  5. 5. Putting Geothermal Energy to Use<br />
  6. 6. Geothermal Heat System<br />A basic Geothermal Heat System consists of three parts:<br />The ground loop <br />A heat pump<br />A Heat distribution system<br />
  7. 7. The Ground Loop<br />
  8. 8. The Ground Loop - Closed<br />
  9. 9. Vertical Closed Ground Loops<br />
  10. 10. Horizontal Closed Ground Loops<br />
  11. 11. “Slinky” Closed Ground Loop<br />
  12. 12. Pond Closed Loop<br />
  13. 13. The Ground Loop - Open<br />In contrast to the closed loop systems, open loop pulls water directly from a well, lake or pond for conditioning purposes. <br />Water is pumped directly into the heat pump where the heat is extracted and then is re-injected into the water source or return well. <br />Depending on factors such as depth, volume, and water quality, bodies of surface water can be used as a source of water for an open-loop system.<br />Ground water can also be used as a source, provided the water quality is suitable and all ground water discharge regulations are met.<br />
  14. 14. The Heat Pump<br />
  15. 15. Heat Pump Options<br />Water-to-air<br />The water-to-air heat pumps are designed to replace a forced air furnace and/or central air conditioning system. This system can produce heat during winter and air conditioning during summer.<br />Water-to-water<br />A water-to-water system heats water to be used in radiant floor heating and/or domestic hot water.<br />Hybrid<br />A hybrid system is capable of producing heated water and heated or cooled air simultaneously.<br />

  20. 20. Environmental Incentives<br />Geothermal energy is environmentally friendly and self-renuing.<br />The U.S. Environmental Protection Agency (EPA) has called geothermal the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available. <br />Today there are more than 1,000,000 geoexchange systems in the United States. The current use of geothermal technology has resulted in the following emissions reductions:<br />Elimination of more than 5.8 million metric tons of CO2 annually <br />Elimination of more than 1.6 million metric tons of carbon equivalent annually <br />The impact of the current use of geoexchange is equivalent to:<br />Taking 1,295,000 cars off the road <br />Planting more than 385 million trees <br />Reducing U.S. reliance on imported fuels by 21.5 million barrels of crude oil per year.<br />
  21. 21. Economic Incentives<br />Save 30% to 70% annually on utilities.<br />High initial costs, but relativly short payback period, typically between 3 to 5 years.<br />Geothermal heat pumps carry the Department of Energy and the Environmental Protection Agency's ENERGY STAR label. <br />ENERGY STAR-labeled equipment can be financed with special ENERGY STAR loans. <br />Some loans have lower interest rates, longer repayment periods, or both. <br />The life span of the system is longer than conventional heating and cooling systems. <br />Most loop fields warranted for 50 years.<br />Some electric companies offer special rates to customers that install geothermal systems. <br />When upgrading a home’s energy efficiency, these improvements can be financed through "energy efficiency mortgages.”<br />
  22. 22. For the Homeowner<br />Consider the following before installing a geothermal heat system. <br />You will need space outside your house for the ground loop. <br />The ground will need to be suitable for digging a trench or borehole. <br />What fuel is being replaced? If it's electricity, oil, LPG or coal the payback will be more favourable than gas. Heat pumps are a good option where gas is unavailable. <br />Is the system for a new building development? Combining the installation with other building works can reduce costs. <br />Have you installed insulation measures? Wall, floor and loft insulation will lower your heat demand and make the system more effective. <br />To increase sustainability, buy green electricity, or install solar PV or some other form of renewable electricity generating system to power the system. <br />Most geothermal systems are covered under your homeowner's insurance. <br />Contact your insurance provider to learn about their policy. <br />

  24. 24. Cooling System?<br />As previously mentioned, a radiant floor heat distribution system does not allow for a cooling mode. <br />However, (COMPANY’S) homes are built to a standard such that there is no need for such a system.<br />(Built Green) homes are constructed using Structurally Insulated Panels (SIPs) that keep the home so well insulated that a cooling systems becomes obsolete. <br />
