Ground Source Heat Pumps - How do they work? A comprehensive guide by Summit Energies

Ground Source Heat Pumps are a cost effective and efficient way to heat your home or commercial property during the winter months and cool your property in the summer months. At Summit Energies we have been installing ground source heat pumps in South Wales and beyond for many years. Our team are trusted installers of ground source heat pumps with over 50 years of experience in the heating sector.

How Ground Source Heat Pumps Work

Ground source heat pumps work in a simple yet effective way, they transfer heat from the ground into your home or business during the winter and reverse the process during the summer to keep the property cool. This will reduce the need of installing internal fans and heaters that would use excessive amounts of electricity.
A ground source heat pump system consists of a series of pipes which are installed and buried underground outside your property, the pipes are then connected to a heat pump unit which is then installed inside the property.

Benefits of Ground Source Heat Pumps

Energy Efficiency and Cost Savings

One of the primary benefits of ground source heat pumps is their high energy efficiency. Unlike conventional heating systems that burn fossil fuels, GSHPs use electricity to transfer heat, making them significantly more efficient. For every unit of electricity used, a GSHP can generate three to four units of heat, resulting in lower energy bills and reduced greenhouse gas emissions.

Environmental Impact

GSHPs are an environmentally friendly heating solution. They produce no onsite emissions and significantly reduce the reliance on fossil fuels. By using the renewable energy stored in the ground, they help decrease carbon footprints and contribute to a more sustainable future. Additionally, the installation of GSHPs can often qualify for government incentives and grants aimed at promoting renewable energy technologies.

Reliability and Longevity

Ground source heat pumps are known for their durability and long lifespan. The underground components can last up to 50 years, while the heat pump itself typically has a lifespan of 20-25 years with proper maintenance. This reliability ensures a consistent and dependable source of heating and cooling for many years.

The Installation Process

Site Evaluation and Design

The first step in installing a ground source heat pump is a thorough site evaluation. This involves assessing the property’s heating and cooling requirements, the available land area for the ground loop, and the soil conditions. At Summit Energies, our experienced team conducts detailed evaluations to design a system that meets the specific needs of each client.

Ground Loop Installation

Once the design is finalised, the installation of the ground loop begins. There are two main types of ground loops: horizontal and vertical. Horizontal loops are laid in trenches about 1-2 metres deep, making them suitable for properties with ample land. Vertical loops are installed in boreholes up to 150 metres deep and are ideal for properties with limited space. Our team at Summit Energies ensures the ground loop is installed efficiently and with minimal disruption to the property.

Heat Pump Installation

After the ground loop is in place, the heat pump unit is installed inside the building. This unit connects to the ground loop and the building’s heating system. Our skilled technicians ensure the system is integrated seamlessly, providing optimal performance and efficiency. We also offer guidance on how to operate and maintain the system to ensure it runs smoothly for years to come.
