    Is My Garden Big Enough for a Ground Source Heat Pump?

    Garden size requirements depend on whether you choose horizontal ground loops or vertical boreholes.

    Garden Space Requirements

    There are two main types of ground source heat pump systems, each with different space requirements. The right choice depends on your available land and budget.

    Horizontal Ground Loops

    Pipes laid in trenches at 1-2 metres depth across your garden.

    • Space needed: 150-300 sqm
    • Trench depth: 1-2 metres
    • Cost: Lower installation cost
    • Disruption: Significant during installation

    Vertical Boreholes

    Deep holes drilled 75-200 metres down, requiring minimal surface area.

    • Space needed: Just drilling rig access
    • Access required: 6m x 4m minimum
    • Cost: Higher installation cost
    • Disruption: Minimal garden disruption

    Quick Garden Size Guide

    • Under 100 sqm: Vertical borehole system recommended
    • 100-200 sqm: Either system may work, depending on heat demand
    • Over 200 sqm: Horizontal loops often more cost-effective

    Other Considerations

    • Trees and roots: Loops should be kept away from large trees
    • Soil type: Clay, sand, and rock have different heat transfer properties
    • Future plans: Consider if you plan to build extensions or add pools
