I'm in charge of marketing at a rural power district in Southwest Nebraska and we want to increase the number of geothermal units installed by our customers. At the moment most of our HVAC dealers give the customer two loop options, vertical or pump-n-dump. I understand that the horizontal loops are less expensive and there are three options-- normal, slinky or boring. We want to be able to get the HVAC dealers to look at other less expensive options for the loops, hoping that there are more installations because of a lower installation cost. I'm looking for some input and advice from anyone on how we can accomplish our goal.
