Geo-thermal Heat Pumps

Geo-thermal heat pumps work by moving heat not by producing it.  Heat is absorbed from the ground and “boosted” or “concentrated” and put into your home. 

Geo-thermal system are not new.  Geo-thermal systems have been on the market for over 20 years.  It is a proven technology whose time has come. 

Lang Heating and Cooling has a full line of residential and light commercial geo-thermal heat pumps.  We deal with some of the biggest and largest manufacturers of these systems. We have the software and capabilities to correctly size these systems and calculate projected fuel savings. 

Why Choose Geo-thermal? 

• Savings:  Generally no other heating and cooling system offers lower operating cost as much as 60% compared to ordinary systems.

• Comfort: These systems provide even temperature throughout the home year round, and excellent dehumidifying during cooling.

• Environmentally Friendly:  Geo-thermal is a clean, green, and renewable technology to reduce your carbon footprint now and for future generations.

• Quite Operation: Unlike ordinary air conditioners and heat pumps no outdoor unit is needed.

• Flexibility:  Heating, cooling, and supplemental hot water heating from a single unit.  Wide variety of units and options to fit most applications.

• Free Hot Water:  When unit runs excess heat is used to produce hot water.  This is a supplement to the normal hot water heater.

• Clean and Safe: No fuel, no flame, no chimney.

• Tax Credit: Geo-thermal heat pumps qualify for a 30% income tax credit with no limit which helps reduce the installation investment.

Installation

Geo-thermal heat pumps use the warmth of the earth to operate.  The heat can be collected from the ground by using closed or open ground loops.  Open consist of a well to draw water and a place to dump the water.  These are the simplest type but have high water usage, and usually will not last as long as closed loop.   

Closed loop system can be horizontal, vertical, or pond loops.  Horizontal loops are pipes buried in the ground at about 5” deep.  This type requires from 500 to 1,500 feet of trenching.
Vertical loops are installed by a well-driller.  The vertical bores are drilled and u-bend pipe is inserted, and the hole around them is refilled with grout.  The vertical bores are anywhere from 250’ to 450’ deep, and most systems require multiple bores.
