Ground Source Heat Pumps

Ground Source Heat Pump

Ground source renewables, commonly referred to as geothermal energy or ground source heat pumps (GSHP), utilise the natural warmth accumulated in the earth to offer environmentally friendly alternatives for heating and cooling purposes. 

This innovative renewable energy technology capitalises on the consistent temperatures present below the Earth’s surface, allowing for the extraction of heat for space heating or cooling of buildings, thereby promoting sustainable and energy-efficient solutions.

Ground Source Heat Pump

How Does Ground Source Heat Pumps work?

Ground source heat pumps (GSHPs) work by utilising the relatively stable temperature of the ground to provide heating, cooling, and hot water for residential, commercial, and industrial buildings. 

These systems consist of three main components: the ground loop, heat pump unit, and the distribution system.

Ground Loop

The ground loop is a closed-loop system of pipes buried in the ground. These pipes are typically made of high-density polyethylene and are filled with a heat transfer fluid (usually a mixture of water and antifreeze). The loop can be installed horizontally in trenches or vertically in boreholes, depending on available space and geological conditions.

Heat Pump Unit

The heat pump unit is located inside the building and consists of a compressor, condenser, expansion valve, and evaporator. The heat pump extracts heat from or transfers heat to the ground loop, depending on whether heating or cooling is required.

Heating Mode

In heating mode, the fluid in the ground loop absorbs heat from the ground, which is at a relatively higher temperature compared to the ambient air during colder months. The heat pump compresses the absorbed heat, increasing its temperature further, and transfers it to a higher temperature fluid in the distribution system, which circulates throughout the building.

Cooling Mode

In cooling mode, the heat pump reverses the process. The fluid in the ground loop absorbs heat from the higher temperature fluid in the distribution system, which has absorbed heat from the building. The heat pump then transfers this heat to the ground, which acts as a heat sink, effectively cooling the fluid. The cooled fluid is then circulated back to the building to provide cooling.

Distribution System

The distribution system distributes the heated or cooled fluid throughout the building. It typically consists of underfloor heating pipes, radiators, or air handling units, depending on the specific requirements of the building.

The heat pump unit continuously monitors and adjusts the system’s operation to maintain the desired indoor temperature. GSHPs can achieve high energy efficiency because they rely on the stable temperature of the ground, which remains relatively constant throughout the year, as opposed to the more fluctuating ambient air temperature.

Overall, ground source heat pumps provide a sustainable and efficient solution for heating and cooling, utilising the Earth’s natural heat to reduce energy consumption and greenhouse gas emissions.

Where Ground Source Heat Pumps Can Be Used

They can be used in various applications, from residential homes to large-scale commercial buildings, and are particularly effective in areas with moderate climates.

By utilising the heat stored beneath the Earth’s surface, ground source renewables play a vital role in transitioning towards a more sustainable and low-carbon future, reducing reliance on fossil fuels and mitigating the environmental impact of heating and cooling systems.
