Breakthrough Technology
Do you need affordable geothermal installed where you have limited space or restricted access adjacent to your home or business? Our novel concentric pipe borehole heat exchanger is the solution.
The concentric pipe heat exchanger allows shorter boreholes that are accessed and drilled using smaller equipment, ...
The Market
This site had a small back yard area 16 ft X 37 ft (600 ft2). The well field was drilled and installed within grass using a remote-controlled, tracked drill rig. The rig accessed the area through a fence panel at the back of the property.
The well field included 6 boreholes, drilled to 50 feet, along angles 30 ...
Field Trial
Our patented Concentric Pipe geothermal heat exchanger reduces the required length of wellfield, reducing the total installation cost and making a renewable energy solution more affordable and accessible for homes and small businesses. If you want geothermal heating and cooling, but are faced with higher costs ...
The Concentric Pipe Heat Excanger
Two Heat Transfer Modes
Convection Q˙=h A ΔT (BTU/hr)
Convection requires fluid flow in the heat exchanger which cycles on and off with the thermostat. This is an issue because, even for extreme temperatures, convection is active less than half the day and generally one sixth to one quarter of the day (4 to 6 hours)....
