Checking the charge
Tim checking the charge for one of four units replacing oil heat in a commercial building.
A clean easy to work on layout
In the lower part of the cabinet to the right, you can see the two compressors that allow this advanced design to be efficient.
The indoor units
There are two air handlers and the associated duct work in a storage area that used to be filled with oil tanks.
Digital thermostat and information center
The control of the system is from a glow in the dark, digital touch pad. It can tell you the status of the system, let you program detailed temperature profiles for different times of day, or simply adjust the temperature by a degree or two.
Geothermal Drilling Operation
Posted on July 30th, 2008 by admin
This is a example of a residential GeoExchange drilling operation. Multiple wells are drilled and the pipes placed in them are connected to a manifold. Pipes in a trench will connect to the rest of the equipment inside the home’s basement. After installation, there are no visible outdoor components.
