125 degrees....that was the temperature of the water going into my geothermal heat pumps last night. No wonder our system is shutting down. It's never really worked...first they said it was the duct work, then lack of vents, and our R50 insulation in the attic was not enough. It's amazing what happens when you add COOLANT !!! Yes... no coolant in the system. It took many visits from Planet Geothermal and over 9 months to figure out why our system would not cool or heat our brand new home. Now it only barely works....well they're 3 tons short, we had to hire a professional for $700 to do a proper heat load calculation. We have a 3 ton and 5 ton unit, tranquility 27 split hooked in series. Yes, series not parallel as designed by the manufacturer and our installer REFUSED to change it (along with the damper installed backwards, and the filter that is 1/2 inch to large) It's sad when a housewife knows more than Dave, our GeoThermal contracted specialist. What do you do with loops at 110 - 125 degrees?? A. abandon system and put in all new conventional high efficient system. B. tear out poor duct system and replace with hard duct instead of flex tubing (that looks like spiderman's hideout) and hope that fixes it. C. Spend $11,000 for a cooling tower and then redo duct work. D. Add a conventional 4 ton unit to the house, sparingly use GeoThermal and hope the loop temp drops in the winter. while redoing all duct work. E. B C and D (est. $25,000) (ie adding loops is not possible, the lava we are on (that Planet Geothermal said would be no problem) was so hard to drill that his drillers will not come back. Any ideas, comments, leads to someone who could help would be appreciated. If we don't resolve this soon, we'll be moving into our in-laws home. Thanks!
