I don’t give negative recommendations for contractors lightly. After all the problems and screw ups the contractor did, I never identified that actual company that did the installation, but I can only take so much. When I ordered the system I had emergency heat installed, but I specifically told the sales person and told the installer several times I did not want the emergency heat to kick on, ever. I only wanted it installed so I would have heat in a situation such as the water pump died, I would have some heat until it could be fixed. Well the power failed tonight, it was off roughly 3 hours, after the power came back on, the house temperature was 59 degrees, roughly 9 degrees below what I normally keep the system set at. Ok no problem, the system will just take longer to catch up, but I noticed 30 minutes later, it’s 68 degrees in the house already. Way too quick for a geothermal system, I check the heat coming out from the heating vents and its HOT, I check the unit and its hot on the top where it’s blowing the air into the house. Well I’m really pissed at this point, I stressed exactly what I wanted and the contractor didn’t deliver. After looking at the wiring diagram, I identified the dip switch what needed to be turned off to prevent the aux heat from kicking on and flipped it. So I don’t think it will happen again. If your looking for a Heating Contractor in South Jersey, I can not recommend Laury Heating of Vineland New Jersey.     

The system is an open loop, what i want is a system that runs effiecency as possible, Im not concerned that it will take the system a little longer to recover when the temperature is below normal. Besides I leave it at a set temperature now, unless there's a power failure like I had today, there should be no reason for it to drop more than a degree or two below the set temp.
