Ground Source Heat Pump and Underfloor Heating in Sussex

Client brief

The owners of a new build property in Sussex wanted an energy-efficient, future-proof heating solution that would provide comfortable, low-carbon warmth throughout the home. The brief required a complete ground source heat pump system integrated with underfloor heating to deliver sustainable heating and long-term energy savings.

Our solution

Better Planet provided a full design, supply, installation, and commissioning service, starting with a detailed room-by-room heat loss calculation to correctly size the heat pump and underfloor heating system.

Key system components:

  • Heating system:
    • NIBE F1345 – 30kW Ground Source Heat Pump for efficient, low-carbon heating.
    • 500L and 300L Heat Pump Cylinders to ensure ample hot water supply.
    • 300L Buffer Tank to optimise system performance and temperature stability.

  • Ground loops:
    • Heat collected from the field using 1.2 km of 40mm collector pipe, installed with trenching machinery subcontracted by Better Planet.
    • Four ground loops of 300m each, connected via a ground manifold with 63mm flow and return pipes to the plant room.

  • Underfloor heating:
    • 16mm PERT pipe from Swedish manufacturer LK for durable, efficient heat distribution.
    • Screed system on the ground floor and dry screed boards for the first and second floors.
    • Heatmiser Controls for precise, user-friendly temperature management throughout the property.

This fully integrated solution ensures optimal comfort, energy efficiency, and low operating costs while enhancing the property’s long-term sustainability credentials.

Project success

  • Efficient, low-carbon heating: The ground source heat pump and underfloor heating system deliver even, comfortable warmth across all floors with significantly reduced carbon emissions.
  • Lower energy costs: The renewable heating system provides long-term energy savings by reducing reliance on fossil fuels and optimising efficiency through modern controls and a well-designed system.
  • Future-proofed comfort: The integration of underfloor heating and renewable technology ensures a modern, sustainable home that meets current and future energy efficiency standards.
