Trane Geothermal Heat Pump Features

The Trane geothermal heat pump comes in many different models and sizes. In fact, if you are searching online for any geothermal heat pump the industry name for it is......water source heat pump.

Below is my review of the features, benefits, and options among the many Trane geothermal heat pump models.



Trane GEH/GEV - Residential

GEH: Horizontal unit configuration

GEV: Verical unit configuration

Capacity: 1.5 - 5 ton (typically residential 600-800 sq. ft per ton cooling)

Compressor: Rotary and scroll

Cabinet: Galvanized Heavy Gauge Steel

Operating Range: 25 - 110 F entering fluid temperature, 55 - 95 F entering air temperature.

Airflow Configurations: A left and right side return is available on all GEH models with a left, rear, or right side supply. A left and right side return is available on all GEV models with a top or back supply.

Sound Attenuation: Every unit comes with a standard sound attenuation package. For added cost, a deluxe sound attenuation package provides thicker cabinetry and a foam gasket sealant placed around the perimeter.

Auxiliary Heat (Optional): Electric Heat can be added to this Trane geothermal heat pump. This allows a boiler or furnace to be removed from systems in climates that require only 15 - 30 days of heating.

Waterside Economizer (Optional): If the outdoor temperature is low enough to provide cooling without operation of a compressor, an internal diverting valve will allow cooling use outdoor air temperature.

Hot Gas Reheat (Optional): If dehumidification is desirable for your home or building, the hot gas reheat option can be selected. In this operation, a coil is added to the airstream, heating the air after leaving a cooling coil. This lowers the relative humidity of the air.

For more information take a look at the Trane geothermal heat pump product catalog for the GEH/GEV models.


Trane GEH/GEV - Commercial

GEH: Horizontal unit configuration

GEV: Verical unit configuration

Capacity: 6 - 25 ton

Compressor: Scroll R-410a (eco-friendly)

Cabinet: Galvanized Heavy Gauge Steel

Operating Range: 25 - 120 F entering fluid temperature, 55 - 85 F entering air temperature.

Airflow Configurations: A left and right side return is available on all GEH models with a rear or right side supply. A front return is available on all GEV models with a top or back supply. A back return comes with a front or top supply.

Sound Attenuation: Special sound attenuation is not available on these models.

Auxiliary Heat (Optional): Just like the residential versions of the GEH and GEV model, an electric heater option is available.

Waterside Economizer (Optional): Using a low outdoor air temperature during cooling mode is used if this option is selected. This can save energy during low ambient conditions.

Hot Gas Reheat (Optional): This option gives you the opportunity to dehumidify your home or building.

Trane EXH - High Efficiency

The EXH Trane geothermal heat pump is a high efficiency version of the GEV and GEH residential models.


Trane VS - Variable Speed

Trane's VS model uses cutting edge technology which varies the speed of the compressor. What is the benefit of this?

During periods where the heat pump requires a small amount of heating or cooling, the compressor motor rotates at a lower speed, resulting is less cooling or heating provided to the house or building.

The key here.....

In most air conditioners or heat pumps, the compressor still uses a comparatively large amount of energy during periods of low heating or cooling.

..... However this is not the case when the compressor motor is spinning slower due to a variable speed drive!

This Trane geothermal heat pump is a very high tech, high efficient option!


Trane GERA - Rooftop Heat Pump

Most commercial and industrial buildings utilize space on the roof for the HVAC equipment.

To satisfy that sector of the market, this Trane geothermal heat pump uses the same technology from other Trane Axiom models, and applies it to a rooftop configuration.

Since many commercial buildings contain a lot of ductwork, these rooftop units can be ordered with a standard static or high static fan. A building will require a high static fan if there are long runs of ductwork or duct fittings.

This unit may also be ordered with a belt-driven motor which, if the motor is over-sized, can re-sheaved allow for more airflow or higher static pressure.


Trane Water to Water WSHP

Most heat pumps that are discussed on this website are air conditioning heat pumps. In other words, the purpose of the heat pump is to cool or heat air.

The purpose of a water to water WSHP (water source heat pump) is to heat or cool water (or some mixture of water with an antifreeze).

This is often used in a large building where there are many offices or rooms that contain separate coils for heating or cooling the air. For example during the summer cold water flows through these coils and a fan blows are across the coil, thereby cooling the air.

Below are a few features of this Trane geothermal heat pump:

Capacity: 2 - 6, 20 ton

Compressor: Scroll R-410a (eco-friendly)

Operating Range: 25 - 120 F entering fluid temperature

Sound Attenuation: Compressor contains vibration mounting for noise attenuation. Water to water heat pumps do not contain fans, so the noise level is dramatically reduced compared to a standard heat pump.

Modular: These heat pumps are rack-able and can be cascaded to increase the total cooling or heating capacity of the entire system.


Console and Vertical Stack Heat Pumps

Trane also offers heat pumps that can be separately installed in places such as hotels, office buildings, or schools.

Most hotel rooms contain fan coil or console units allowing for easier control and supply of on-demand requirements in each room.

These units apply the Axiom heat pump concept to the individual room air conditioner and heater.
