ALT Power Systems Geothermal Heating Radiant floor Heating Reflective Foil Insulation
Geothermal General 1. How does a geothermal system work? –In the winter earth loop absorbs stored heat from the ground which is compressed to a higher temperature and distributes it throughout the building –In the summer, the system reverses, pulling heat from the building, depositing it in the cooler earth. 2. What makes a geothermal system different from conventional systems? –Unlike conventional systems, geothermal systems do not burn fossil fuel to generate heat--they simply transfer heat to and from the earth. 3. How efficient is a geothermal system? –Geothermal systems provide three to four units of energy for every one unit used to power the system.

Earth Loop Options With Copper pipe: Horizontal Loop (Pit or Trench), Vertical Loop, and Diagonal Loop
Heating Water The Geothermal heat pumps can be used to heat the water for your home. This can be accomplished in two different ways: The Geothermal heat pumps can be used to heat the water for your home. This can be accomplished in two different ways: – through integrated full-time water preheating –or through "desuperheating" water heating.
Water Heating (cont.) Integrated water heating (on demand) uses the Geothermal system to heat water at any time of the year. Its first cost is higher, but it provides operating savings all year. It provides quicker recovery from a cold water tank than does an electric resistance water heater.

Water Heating Desuperheating Water Heating Desuperheating water heating reclaims heat from the A/C cycle to heat water instead of pumping it into the ground. Its first cost is lower. Savings are realized in the cooling season by transferring waste heat to your hot water storage tank. Even in the heating mode the desuperheater can provides pre-heating to the water heater. (You can scavenge heat from the heating cycle)
Radiant Floor heating Radiant Floor Advantages Comfort- The floor becomes the radiator, no cold spots Healthier- less airborne dust & mold spores Less Drafts- Does not create drafts caused by other types of heat Fuel Efficient- Uses less fuel than any other distribution system Flexibility- Can be installed in new and existing homes
Radiant Heat (cont) Radiant heat is actually a low frequency radio wave that flows from the object with the highest temperature and is absorbed by any object that has a lower temperature. it does not heat the air between the two objects it's ability to heat only those objects that need heat. Even heat. Even heat. heat from the sun comes to the earth in the form of radiant energy and heats the objects on earth.
Eco Center Mini Mail Geothermal Heating, Radiant Heating and Reflective insulation was used in 60% or 4640 sq ft. of this building.
EcoCenter (cont.) Electrical bill for Jan/04 was $370.80 3625 KWH @.0777 cent/kwh = $281.66 monthly charge = $18.34 Municipal surcharge = $30 GST and PST = $40.80 Day time use no heat 1456 kwh@.0777 = $113 Heating for Jan/04 = $168.66 If you can do everything with one utility you only have the one monthly charge. The gas delivery & monthly charge is around $60
Power Bills First full month Electrical bill (Heat pumps, and all our lights and work benches not hooked up yet.)
EcoCenter Heating for 03/04 Oct Heating 161.98 – 113 = $48.98 Nov Heating 188.66 – 113 = $75.66 Dec Heating 276.92 – 113 = $163.92 Jan Heating 281.66 – 113 = $168.66 Feb Heating 211.96 – 113= $98.96 Mar Heating 194.89 – 113= $81.89 April Heating (use same as Oct) = $48.98 Total for 03/04 winter Heating for 4640sq ft at EcoCenter = $673.09 Average per month is $96.16
