How does a ground source heat pump work?

A ground source heat pump operates by leveraging the stable temperatures found beneath the surface of the ground to efficiently heat buildings. Here’s a simplified explanation of its heating operation:

Ground Source Heat Pump Temperature

The Basic Principle

Beneath the surface, the Earth maintains a nearly constant temperature throughout the year, which is typically warmer than the winter air temperatures above ground.

GSHP systems utilize this consistent underground temperature to extract heat for heating buildings.

System Components

  • Ground Loop: A series of pipes buried near the building, filled with a water-based fluid capable of absorbing and transferring heat.
  • Heat Pump Unit: Installed inside the building, it includes a heat exchanger and a compressor.
  • Distribution System: Circulates air or water throughout the building, delivering heat where needed.

Heating Mode

  • The fluid in the ground loop absorbs heat from the surrounding ground.
  • This warmed fluid is then pumped through the loop to the heat pump unit inside the building.
  • Within the heat pump, the heat from the fluid is transferred to the refrigerant in the heat exchanger.
  • The compressor increases the temperature of this heat to a level suitable for heating.
  • The heated air or water is then distributed throughout the building via the distribution system to warm the interior spaces.

Efficiency

GSHPs are highly efficient for heating because they transfer heat rather than generate it through combustion or electrical resistance, which requires significantly less energy. The efficiency is bolstered by the ground’s consistent temperature, providing a reliable and efficient source for heat exchange.

In essence, ground source heat pumps utilise the stable underground temperature as a source for heat exchange, offering an efficient and cost-effective heating solution with lower operating costs and a reduced environmental impact compared to traditional heating systems.

Should I get a ground loop or a borehole heat pump system?

Deciding between a ground loop and a borehole heat pump system for a ground source heat pump installation largely depends on factors such as your property’s size, soil composition, budget, and heating requirements. Here’s a comparison:

Ground Loop (Horizontal Installation)

  • Space Requirement: Requires significant land since pipes are laid out horizontally in trenches about 1-2 metres deep. It’s ideal for properties with ample space to effectively absorb ground heat.
  • Cost: Generally, less expensive than borehole installations due to simpler drilling processes.
  • Soil Conditions: Efficiency varies with soil type and moisture, with wetter soils often providing better heat conduction.
  • Best For: Properties with enough land for trenches and where budget is a key consideration.

Borehole Heat Pump System Vertical Installation

Borehole Heat Pump System (Vertical Installation)

  • Space Requirement: Suitable for properties with limited space. Pipes are installed vertically, requiring deep drilling (60 to 200 metres or more), making it practical for smaller plots.
  • Cost: More expensive upfront because of the extensive drilling required. However, the potential for higher efficiency and lower operational costs can offset the initial investment.
  • Soil Conditions: Less affected by soil type due to the consistent, often warmer, temperatures found at deeper levels.
  • Best For: Properties with limited outdoor space, in urban settings, or where the geological conditions favour deep drilling. It’s also for those willing to invest more initially for long-term savings.

Making Your Decision

  • Assessment: Conduct a detailed assessment of your property, considering space, soil conditions, and climate, to determine which system is more efficient and cost-effective for heating.
  • Professional Consultation: Engaging with one of our GSHP professionals can provide insights into the most suitable option based on your heating needs and property characteristics.
  • Regulations and Incentives: Investigate local regulations and potential incentives for GSHP installations, as these can influence your choice.

The decision between a ground loop and a borehole system should be based on evaluating your specific situation and heating objectives. Both options offer GSHP benefits such as high efficiency, environmental friendliness, and lower heating costs, but their feasibility and efficiency will differ according to your property’s unique features.

How much is a ground source heat pump to install?

The cost of installing a ground source heat pump in the UK varies widely depending on several factors, including the size of the system, the type of ground loop (horizontal or vertical), the soil composition, and the overall complexity of the installation. Here’s a rough guide to the costs:

GSHP Installation Cost
  • Initial Costs: The installation cost of a GSHP system starts at about £20,000 for smaller residential systems. For larger homes or properties needing more substantial heating capacities, the cost will rise accordingly. Our proposal costs are all-inclusive: the cost of the heat pump unit itself, the ground loop, all accessories, and installation labour.
  • Borehole Drilling Costs: If a vertical borehole system is chosen due to space constraints or soil conditions, the drilling can significantly increase costs. Drilling a borehole generally costs between £65 and £90 per linear metre, and a typical home might require boreholes drilled to depths of 100 metres or more, which does add significantly to the overall cost.
  • Operating Costs: While the upfront costs are high, it’s important to consider the operating costs. GSHPs are highly efficient and can lead to significant savings on heating bills over time. The precise savings will depend on the previous heating system replaced and the property’s insulation quality.
  • Incentives: The UK government has offered various incentives to encourage the adoption of renewable energy sources, including heat pumps. At the moment, a grant of £7,500 is available via the Boiler Upgrade Scheme (BUS). Contact us for further details and to check eligibility.

What’s the difference between a ground source and an air source heat pump?

Ground source heat pumps (GSHPs) and air source heat pumps (ASHPs) both provide efficient heating solutions, but they differ in their operation, efficiency, installation requirements, and costs, focusing primarily on heating. Here’s a comparison:

HEAT PUMP TYPE
GROUND SOURCE
AIR SOURCE
Heat Source & Operation
GSHPs harness heat from the ground through pipes buried underground, utilising the consistent temperature beneath the Earth's surface. This allows for efficient heating even when the air temperature is cold.
ASHPs extract heat from the outdoor air. They can still function in cold weather by absorbing heat from the outside air and bringing it indoors.
Efficiency & Cost
Tend to be more efficient than ASHPs for heating, as they leverage the stable underground temperature. The initial installation cost is higher due to the ground loop or boreholes, but this can be mitigated by lower operating costs and a longer lifespan.
Have a lower upfront cost and are still very efficient, although their efficiency can drop in very cold climates. Technological advancements have improved their performance in colder regions.
Installation & Space Requirements
Installation is more complex, requiring space for ground loops or vertical drilling for boreholes. The system's efficiency and feasibility depend on the property size and soil conditions.
Are easier to install with minimal space requirements, making them suitable for various properties, including those with limited outdoor space.
Environmental Impact
Generally have a lower environmental impact in terms of electricity usage and emissions, benefiting from the ground’s stable temperatures for efficient heating.
While efficient and better for the environment than traditional heating methods, their performance can be slightly lower than that of GSHPs in extreme weather conditions.
Maintenance & Lifespan
Offer a longer lifespan, with the ground loop system lasting over 50 years and indoor components around 25 years, requiring less maintenance.
May have a shorter lifespan due to outdoor units being exposed to the elements, necessitating more regular maintenance for optimal performance.

When considering a heating system, the choice between a ground source and an air source heat pump depends on factors such as budget, property characteristics, and climate.

GSHPs are more efficient and have lower operating costs but come with higher initial costs and space requirements.

ASHPs are easier to install and less expensive upfront but might be less efficient in very cold climates.
