We agree that one should not jump to conclusions too early.  When Linda and I saw the first usage bill, we considered all of the possibilities including the electrical usage related to installation.  We considered the initial readings and subsequent daily readings to be an indication that something wasn’t right but wasn’t certain.  Following the great advice received in this forum, we began monitoring incoming water temps. We began a daily log of kilowatt usage.  We watched everything used in the house to make sure that we had not increased use in another area.   Various individuals on this site have requested data and information.  Their comments and recommendations have been greatly appreciated. I began using some of the watering techniques recommended to achieve some compaction.  (We do not have a well, so electrical pump usage is not a factor.)  To date incoming water temps do not meet specs.  Based on information received from this forum, the system cannot achieve the desired efficiency under the present incoming water temps.   What I have learned is that there is little or no compaction.  Once you punch into the trenches at almost any point (using a pipe attached to a water hose), there are large voids where no soil is compacted around the pipes.  I have attained some compaction but have a long way to go.  Where I have worked on the trenches, there is now anywhere from six inches to two feet drop in the trench level.  I have not replaced or added any soil to the trenches where I have been working.  I am still trying to get the contractor back out here and want him to see this for himself.  We have seen some drop in the incoming temps.  We were getting readings 110.  Now seeing 95-100.  There have also been some weather changes including the first rains in months.  Until the trenches are properly compacted and additional soil added, true results are uncertain.  Changes in weather will also be a factor.  I intend to post all of our readings and compaction efforts.  There has been some excellent advice given to us.  I think the fix is forthcoming but will take time.

Just completed lengthy discussion with our installer.  He, in turn, has been in contact with the manufacturer.  He will install a sensor five feet underground to see what the sub-ground temps actually read.  If the desired sub-ground temp can be achieved according to what was projected, then we know to continue with compaction efforts. Should have that data by this weekend.  

Linda,

Did you get your system fixed?  I'm aware of problem installers in Texas and can turn you on to a very reputable geothermal guy to help you debug your install if you still need help.

Thanks, 183eej.  We're hoping to report something similar.  So far, although this result has not been what we expected with regard to the energy savings, costing us more energy usage, I'm impressed with how much more comfortable our house is, even though we've actually had to go up on the temperature settings to at least partially offset the higher energy usage.  So far, too, our installer, although working more slowly than we would prefer, has been great about assuming responsibility.  We'll see if that continues.  If not, I may be taking you up on your suggestion to provide other names.
