Harvest the Heat Beneath Your Feet
EarthLinked Geothermal is a great fit for an existing home, office, or other building. There are very few situations that don't lend themselves to relatively simple retrofits.
First and foremost is performing a load calculation on the structure to correctly determine the size of heat pump the building needs. Without this, everything would just be a shot in the dark.
We evaluate your home, including its measurements, insulation types and thicknesses, window types and sizes, door types and sizes, existing duct work (if any), and overall orientation. Then we enter this information into a computer program that usues the latest version of ACCA's Manual J to calculate your home's heating and cooling loads.
While evaluating the home, we look at possible locations for the earth loop. Things to avoid are: septic system drain fields, corrals, underground utility lines, and trees you may not want to lose.
At this point, we'll decide if horizontal or vertical loops are the better option. If the land area is limited, it is likely that the earth loop will need to be drilled. Surface area required for drilling may be up to a 14 foot diameter circle per heat pump (some homes are large enough to need multiple units). Also, if the soil is full of rock and/or cobbles, drilling may be the better option. However, in areas of very little rock, horizontal may be the lower priced choice.
Now that we have the heating and cooling loads of your home, we can select the proper size of heat pump it needs. Selecting the right size will ensure that your home is heated as comfortably as possible. After all, that's what your heating system really should do--deliver comfort.
For homes with little or no duct work, we will study out what the best route for retrofitting duct work is.
