The basics of geothermal

• 1. .

2. The old method of Residential Heating and CoolingMost homes have a separate heating system which burnsexpensive oil or gas in a furnace. 3. Residential Heating and CoolingThe furnace heats air and sends it through thehome via air ducts to each room.Some homes use boilers to send hot water to radiators. 4. A lot of money goes up thechimneyUnfortunately, especially withfurnaces and boilers built before2000, much of the heat goes upthe chimney instead of heatingyour home. 5. Poor efficiency = Wasted money In fact, according to Consumer Reports, most gasfurnaces built in the 70s had an Annual FuelUtilization Efficiency around 65%. And most oil burners were even worse. 6. Fossil fuels seem more expensiveevery 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 earthInstead of burning fossil fuels, some companies havesolved the problem by taking free energy from theground to keep you comfortable.The process is called GEOTHERMAL heating andcooling. 8. Heat PumpsThe heart of a geothermal systemis the HEAT PUMP which replacesall the components of your oldheating and central air conditioningsystemsWe recommend Next Energygeothermal heat pump systems 9. Free energy from the earthFree energy (temperature) from the earth is brought toa Heat Pump and used to warm and cool your homecompletely replacing the expensive oil or gas youcurrently use.FREEOR$ FORTUNE $ 10. Free energy from the earthA couple feet down, the ground stays approximately 55degrees all year long. And 55 degrees is warm in theWinter and cool in the Summer.It is that temperature differential which makes a heatpump work. 11. Geothermal Energy Efficiency With geothermal, you only pay for roughly 25% of your homes heating and cooling costs, the rest comes FREE from your backyard 12. Heat Pump EfficiencyA conventional furnace is rated on how efficiently it uses fuel.Furnaces from the 70s were typically around 65% efficient. Anaverage furnace today is 80% while a high efficiency unit may be90% efficient.That means for every $1 of fuel you put in, you get 80 or 90 cents ofheat.Heat Pumps are measured in COP Coefficient Of Performancewhich is a measure of how many BTUs of heat are generated fromthe electric energy used.A Next Energy Heat Pump, connected to a geothermal field, canoffer a minimum COP of 4.0 which translates to 400% efficiency.Because you use free energy from the earth, that means for every $1of fuel (electricity) you use, you get $4.00 worth of heat. 13. Heat Pump EfficiencySEER stands for Seasonal Energy Efficiency Rating , it isused to describe the energy efficiency of air conditionersby blending the BTU output of the air conditioner withthe cost of energy used per hour. 14. .Average SEER ratings for air conditioners from the 70s wouldhave been 6 8.Efficiency ratings today start at the Federal minimum of 13with 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/Cefficiency can decrease by over 20% in efficiency!Next Energy Geothermal systems range from 25 - 40 SEERratings and their efficiency remains stable, even on thehottest days! 15. Free Central Air ConditioningIn addition to saying Good Bye to your oil man,another big benefit is that while you are purchasing anextremely efficient heating system for your home you arealso getting a properly sized central air conditioningsystem, virtually for free! 16. Free Central Air Conditioning with aGeothermal 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 comfortSo, go ahead, set the thermostat to be comfortable.No more wearing sweaters in the Winter because it istoo expensive to keep the house at a comfortabletemperature sweaters should be a fashion statement! 18. All you feel is comfortThe heat pump does the rest by simply reversing thedirection the refrigerant flows in the systemThe refrigerant works as well at warming your home as itdoes cooling your home. 19. Heat pumps have been around along 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 pumpsRefrigerator DehumidifierAir Conditioners 20. A refrigerator is a heat pump Coil #2 A refrigerator is a heat pumpoperating in the cooling mode There are two heat exchangecoils and a compressor whichmoves refrigerant betweenthe two coilsCondenserCoil # 1 21. The theory of removing heat A refrigerator feels cool on the inside because heat fromthe inside has been absorbed by refrigerant in thecooling coil. That refrigerant constantly circulates,carrying the heat it just picked up toanother coil on the back where a fanblows air across it, taking the heat away. 22. The theory of removing heatInstead of using outside air which is cold in the Winterand hot in the Summer, a Geothermal system uses theconstant temperature in the earth to warm your home inthe Winter and cool it in the Summer. 23. Methods of extracting energy from the earthTo get energy from the earth, you can drilla well, pump water up to the heat pumpand drop it back down into the ground- that method is called an open loop.Or, insert pipes into borings andrun fluid thru the pipes. The fluid isconstantly circulated, exchangingenergy between the earth and theheat exchanger, that is a closed loopsystem. 24. Pros and cons of open loop systemsOpen loop systemProsGenerally cheaper to installOnly needs two or three wells.ConsDumps water back into aquifer or soil after useRequires high HP pump = expensive to runShould treat water entering systemPump submerged 100+ feet with relatively shorter life expectancyNeeds well drilling truck to repair or replace pump with associated property damageRequires DEC permit and report if failure occursUnknown environmental impact 25. Pros and cons of closed loop systemsClosed LoopProsWarranted 30 yearsSmall, low HP pump at heat pump = low cost of operationPump can be changed in hour if neededNo environmental impactConsDrilling cost can be higher 26. So, how can 50 degree earthtemperatures replace 1600 degreeflames in a furnace A furnace uses flames, created from burning oil or gas, toheat air. When you stop the flames, the area cools quickly toambient temperature and more flames are called for,which means more oil or gas is used. And dont forget, much of the heatfrom those flames goes up the chimney. 27. So, how can 50 degree earthtemperature replace 1600 degree flames in a furnace A geothermal system absorbs ground temperature and carries it toa coil in the heat pump. The refrigerant in the coil either boils or turns cold, depending onwhich way the refrigerant is traveling in the loop. 28. So, how can 50 degree earthtemperature replace 1600 degree flames in a furnaceThat heat (or cold) is then transferred at the second coilin the heat pump which warms, or cools air which thendelivered to every room in your home.Finally, the hot air in your home in Summer, or cold airin your home in Winter, transfers its energy back to therefrigerant which carries it back to the heat pump coiland back to the earth. 29. How about maintenance costs? Remember the refrigerator example? How many times in the last 10 years have you neededsomeone 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 neededsomeone to come fix it, clean it, tune it up or get it going? 30. So, what will it cost? Less than you think, Check out our calculator at :www.integratedgeothermal.com There is a 30% Federal Tax Credit A $1,000 LIPA incentive Most people qualify for a free energy efficiency home audit which can qualify you for up to $25,000 in 2.99% financing which can be billed on your LIPA bill.
