Heat Pump System Commissioning ensures a newly installed heat pump is set up to run safely, efficiently and as intended. It verifies key system settings, checks operation under heating and hot water demand, and fine tunes controls so you get steady comfort without unnecessary running costs.

## 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.

## Frequently Asked Questions

What is heat pump commissioning?

Commissioning is the set of checks and adjustments that confirm a new heat pump operates safely and delivers heat and hot water as intended. It also sets up controls and key temperatures so the system can run efficiently.

When should commissioning be done?

It should be done once the installation is complete, the system is filled and powered, and all controls and emitters are connected. Ideally it happens before the heat pump is relied on for day-to-day heating.

Will commissioning reduce running costs?

Correct settings and controls help the heat pump run at lower flow temperatures and avoid unnecessary cycling, which can improve efficiency. Savings depend on the property, emitters and how the system is used, but commissioning prevents avoidable waste.

Do you commission systems you did not install?

In many cases, yes, provided the system is safe, accessible and ready to test. If issues are found that require changes to the installation, you will be advised on the options before any further work is arranged.

What should I have ready for the commissioning visit?

Ensure power is available to the heat pump and controls, and that the system is filled, pressurised and able to circulate. Having any installation notes, controller manuals and details of room thermostats or zones also helps.
