Air source heat pumps are installed with both an indoor and outdoor unit, requiring specific steps for proper setup. Here's a breakdown of the installation process:

Air Source Heat Pump Installation Process

The installation process involves connecting an indoor unit to an outdoor unit through a wall. Here's a step-by-step overview:

  1. Indoor Unit Placement:
    • The inside unit will usually be positioned on an external wall within the property.
    • It's mounted on a bracket to ensure stability.
    • The location should allow for proper airflow and access for maintenance.
  2. Wall Penetration:
    • The installer drills a hole through the wall at the chosen location.
    • This hole will accommodate the necessary cables and pipes.
  3. Connecting the Units:
    • The installer feeds the cables and pipes through the wall to the outside.
    • These are then connected to the external unit, establishing the connection between the indoor and outdoor components.
  4. Outdoor Unit Placement:
    • The external unit is typically placed in a location that allows for efficient air circulation and is accessible for maintenance.
    • It is often mounted on a base or brackets to keep it off the ground.
  5. Final Checks:
    • After the physical installation, the installer will perform final checks to ensure proper operation and sealing.
    • These checks include checking for leaks, ensuring the system is correctly wired, and testing the heat pump's performance.

Key Considerations for Installation

  • Professional Installation: It is highly advisable that an air source heat pump be installed by a certified professional to ensure proper installation and maximize efficiency.
  • Location Matters: Both indoor and outdoor unit placement are crucial for optimal performance.
  • Regulations: Installers must follow local regulations and guidelines for heat pump installations.
