Heat Pump Consumer Units

Our heat pump consumer units and heat pump boards are built for dedicated air source, ground source and hybrid renewable heating supplies. They give installers a clear route for specifying RCD protection, RCBO protection and surge protection devices where required for inverter-driven heat pump loads.

Use this range when you need a dedicated heat pump power supply board rather than trying to adapt a standard domestic consumer unit. Options include pre-configured boards, Type A or Type B RCD protection, RCBO capacity and enclosures suited to renewable heating installations.

Heat pump circuits can place different demands on the electrical installation because of inverter-driven equipment, start-up current, control gear and wider renewable system integration. Choosing the right board helps keep the installation cleaner, easier to inspect and easier to expand later.

  • Built for heat pump installs – suitable for air source, ground source and hybrid renewable systems
  • RCD and RCBO options – choose suitable protection for the circuit design and manufacturer requirements
  • SPD-ready protection – helps protect sensitive inverter and control equipment from transient overvoltage
  • Installer-focused setup – useful where a dedicated heat pump fuse box or consumer unit is preferred

Specifying a Heat Pump Consumer Unit

Use the heat pump manufacturer’s electrical data and the circuit design as the starting point. Inverter characteristics, starting current, protective device type, surge protection and available supply capacity can all affect the correct board configuration.

Type A Protection

Suitable for some heat pump systems where permitted by the manufacturer and supported by the expected residual-current characteristics.

View Type A RCDs →

Type B Protection

Used where smooth DC residual current may occur and the equipment instructions or circuit design call for DC-sensitive protection.

View Type B RCDs →

RCBO & SPD Boards

Pre-configured boards can combine individual circuit protection, spare capacity and surge protection for a tidy dedicated supply.

Specification Checklist

  • Manufacturer data: confirm supply, protective device and residual-current requirements
  • Design current: coordinate load, conductor size, upstream protection and any starting current
  • RCD type: select from the expected leakage waveform and manufacturer instructions
  • Surge protection: consider the installation assessment and protection of inverter/control electronics
  • Board capacity: allow for required circuits, isolation and sensible spare ways
