Hi all. Just starting out to learn more about residential geo-thermal systems. My question is: Why should a homeowner ask for a geo "cost analysis"? Thanks for your expertise. |

The choice to go geo is based on many factors. there are places in the country where the cost of natural gas is very cheap. So when a low nat gas price is coupled with reasonable electric rates the choice of weather to geo or not is not so easy a decision.
short answer = you need to know about all the costs associated with anything, including cost to operate monthly.

How does then the installer "calculate a cost analysis", to determine what the utility savings may be?

It is a function of many of the different software applications associated with the manual j calculation.

Actually, "what is the make-up" of the different software applications?
Can you post a applicable software application. I'm familiar with the manual j. This is much obliged.

A lot of the software like what my company uses is fairly expensive. Just ask your contractor and most will be happy to show you the cost savings so long as they have the software. If not anybody should be able to do simple math figuring out cost per 100K BTU's for each type of heat source. |

.... So the annual "utility savings" are then based on - Historical whether data/temp. ..(Bin load calc.../Balance point conflict.../Modified Building
Load curves...../?

What really should be done is a deep energy audit - gather a year or more's worth of energy bills (gas, oil, wood, coal, electricity, pellets, whatever) and analyze the WHOLE house so as to figure out where the energy $ are going. The lowest hanging energy fruit may NOT be the HVAC system - could be anything from improving the envelope (reduced infiltration, increased insulation) to simply retrofitting a more efficient pool pump, water heater, or even a couple dozen CFL light bulbs. |
