How Much Land Do You Need for a Ground Source Heat Pump?

Land Requirements by Property Size

The amount of land needed for horizontal ground loops depends on your home's heat demand. Here's a general guide:

Factors That Affect Land Requirements

• Heat demand: Larger or less insulated homes need more ground area
• Soil type: Clay provides better heat transfer than sandy soil
• Loop configuration: Slinky coils need less space than straight trenches
• Climate: Colder regions may need more ground loop capacity

No Space for Horizontal Loops?

If your garden is too small for horizontal ground loops, vertical boreholes are an excellent alternative:

• Only require access for drilling rig (approximately 6m x 4m)
• Minimal permanent land impact
• Higher upfront cost but ideal for smaller plots
