I don't know how to get a lot of the details that will be needed, but I learn fast. The few things I do know are listed below. Geo Excel, closed loop installed Dec 2012 (replaced oil furnace) 2 vertical wells, 270 ft deep. Originally was to be 3 wells 180 ft deep, but while drilling, said ground not stable, caving in, and needed to put in steel casings for a portion of each well. Since casing drove up cost, they said the system could run just as good using 2 deeper wells and increasing loop diameter to one inch. Electric consumption much higher than expected and has continually increased over the 3 years. Before geo, electric usage about 800 kwh/month. After instal, 2500 to 3500 to 4500 per until Feb. I repeatedly asked then to come out and check it. Thermostat replaced 3 times, geo 'thoroughly' checked out at least twice by my request (besides twice yearly maintenance.) This March (2016) electric bill was for $1100, saying we used 9,000 kWh in February. After talking with electric company at length analyzing our appliances, electronics, etc, they said it had to be the Geo system. This time when I called geo company to come check it, they called the manufacturer and found out the flow settings were wrong. The settings were for an open loop. The huge spike in Feb was because aux electric strips were on so much and they got stuck in on position, partially burned out, which he replaced. Since the settings were changed, the kWh usage has decreased a lot, but the change in temp was drastic so I'm not sure I can compare severe winter usage with spring usage. We are using about 1.000 - 1500 avg for Mar Apr and May. A few questions..... would flow settings cause the increase I saw? Would it continue to increase over time (grow more inefficient as time went on)? Would the incorrect settings have other repercussions on my system? (Such as shortening life on my pumps) Who can evaluate my system to make sure it is now done correctly? I feel dependent on the company...I can't change settings, measure flow rates and temps. There were only 3 geo contractors within an hour of me and only 2 responded with quotes for the install. I went with the one that had been in business longer, though they don't do many geo installs. Thanks ahead of time for any guidance.
