Heat Pump System Commissioning

What Heat Pump System Commissioning covers

Commissioning turns a completed installation into a correctly operating heating system. The visit typically includes:

• Start-up checks on pipework, system pressure, air removal and safe operation
• Verification of circulating flow rates and temperature settings
• Setup and testing of controls, schedules and thermostats
• Checking hot water cylinder performance (where fitted), including target temperatures
• Configuration of weather compensation and heating curves where applicable
• Operational checks such as defrost behaviour, noise and vibration observations
• Basic performance checks and fault code review, with clear actions if issues are found
• A practical handover so you understand day-to-day use and what to monitor

Who this service is for

This service is ideal if you have a newly installed air source heat pump that needs final setup, sign-off or troubleshooting before it is relied on day to day. It also suits landlords and small commercial sites that need consistent performance across multiple zones, controls or occupancy patterns.

How commissioning is carried out

Commissioning is completed on site once the system is filled, powered and ready to run. Settings are confirmed against the installed emitters and controls, then adjusted to match your property’s heat demand and how you use the space. You will be shown how to operate the controller, what normal running looks like, and how to avoid common issues such as overheating, short cycling or unnecessary backup heating.

After commissioning: optimisation and ongoing value

Following commissioning, you should have stable temperatures, clearer control over heating and hot water, and a baseline setup that supports efficient operation. If you want further refinement, optimisation visits can be scheduled after a few weeks of real use to adjust the heating curve, time settings and room control strategy based on actual performance.
