Unico System Geothermal Ducted Heating & Cooling Efficiency and Comfort
Direct Energy uses the renown Unico Mini-Duct System (see illustrations below) to supply high quality heating and cooling. This allows homeowners to enjoy the greatest comfort whilst using a renewable energy source.
Quiet Operation and Hidden Ducting
The Unico System’s Air supply ducting is lined with sound attenuating material to assure quiet operation, so comfort is felt but air movement is not heard. The fully enclosed and insulated geothermal system can be located outside or in a basement, utility room or garage so that no component of the system interferes with the quiet living space.
UnicoSystem – Ducted Heating & Cooling
Unico System’s unique cooling method removes 30% more moisture from the air than traditional forced air systems. It draws, rather than pushes, air directly over the evaporator coils, creating colder temperatures than conventional systems. This means that even in the warmest, most humid months the air in your house or office will be dryer, more comfortable.
In colder times and climates, the Unico System delivers comfortable hot air in one of two ways – using either a hot water coil or a true-hot-air heat pump coil – never the scorched air method used by most conventional forced-air systems. Perfect comfort all year-round.
- Better Performance
Even temperatures in any house or office. Eliminates drafts. Flexible tubing also absorbs sounds. - Better Efficiency
Removes 30% more moisture than conventional systems in cooling mode. More comfortable for you, your family and your business. - Matches any Dècor Outlets are small and subtle and can be painted, wallpapered or stained to blend with any dècor.
In existing structures, 2″ (ID) flexible supply ducting can be routed through existing joists in the ceiling, floor or wall cavity, thus eliminating the need for large duct space.
Conventional vs Unico Ducted Heating Systems

Combining Unico with Direct Energy
- Up to 75% energy saving due to reduced energy consumption
- Direct Energy offers the most energy efficient means of heating and cooling buildings in most areas. Transferring renewable energy reduces cooling costs an average of 30% as compared to a 10 SEER air conditioner, and heating costs by 75% as compared to electric heat.
- Reduced emission of greenhouse gases
- Drawing heat from the earth itself, the Direct Energy EarthLinked® system delivers renewable geothermal energy with higher efficiency than any other powered water or associated heating system. The U.S. Environmental Protection Agency has rated it the most environmentally clean and efficient conditioning system.

- Combined heating and cooling system
- Reliable and renewable energy
- The constant earth heat source is always available and is not dependent upon sunlight hours or temperature climate due to the stable temperature of the earth. It can therefore provide reliable heating and cooling.
Why High Velocity Mini-Duct Systems?
High velocity air conditioning and heating systems are the most efficient way to retrofit buildings where:
- no central air conditioning duct work exists;
- unobtrusive ductwork and outlets are desirable to preserve architectural design integrity;
- supplemental cooling or heating is needed for an inadequate existing system; or
- conventional large ducting simply will not fit without major remodeling.
