Heat Pump Performance Optimisation

Heat Pump Performance Optimisation fine-tunes your existing heat pump system so it runs efficiently while keeping your home or premises comfortable. If your system feels expensive to run, struggles to hold temperature, or cycles on and off too often, optimisation focuses on settings, controls and system balance to get the best from what you already have.

More information

What heat pump performance optimisation includes

Optimisation is about matching your heat pump’s operation to the building, your heat emitters and how you use the space. Depending on the system, this can include:

  • Reviewing current comfort and running-cost issues and how the system is being used
  • Checking control strategy (weather compensation, room stats, schedules and setpoints)
  • Adjusting flow temperatures to improve efficiency without sacrificing comfort
  • Improving system balance across radiators or underfloor heating where applicable
  • Reviewing hot water settings (target temperature, reheat timing and anti-legionella cycle)
  • Checking circulation settings and basic hydronic performance (where accessible)
  • Identifying settings or installation factors that can cause short cycling or poor heat-up
  • Clear recommendations if a fault or design limitation sits outside optimisation

When this service is the right fit

This service is most useful when:

  • Your heat pump is working, but bills feel higher than expected
  • Rooms heat unevenly or take too long to reach temperature
  • The system frequently switches on and off (short cycling)
  • Hot water performance is inconsistent
  • Controls feel confusing, or settings have been changed without a clear plan
  • You want a seasonal check to keep performance on track

What happens during the visit

You can expect a practical, methodical approach:

  1. Initial review of your concerns, comfort expectations and typical schedules.
  2. System checks of key settings, controls and how heat is being delivered.
  3. Targeted adjustments to improve efficiency and stability while maintaining comfort.
  4. Plain-English handover explaining what was changed and why, plus what to watch for.

If optimisation highlights an underlying issue (for example, controls wired incorrectly or emitters not suited to low flow temperatures), you will get clear next steps.

After optimisation: keeping performance consistent

Heat pump performance can vary with outdoor temperatures and occupancy. Where helpful, follow-up can include:

  • Advice on day-to-day control use to avoid undoing the gains
  • Suggested tweaks after you have lived with the new settings
  • A plan for further improvements if the system is being held back by design or component choices

Frequently Asked Questions

Will optimisation reduce my heat pump running costs?
Often, yes, particularly if flow temperatures are higher than needed or controls are not set up well. Savings depend on your property, emitters and current settings, and you will be told what improvements are realistic.
Do you need access to all radiators and thermostats?
Access to key rooms, heat emitters and controls helps us balance and verify performance. If some areas are restricted, we can still optimise, but results may be limited.
Can you optimise underfloor heating systems as well?
Yes, optimisation can cover underfloor heating controls and how the heat pump feeds the manifold. We focus on stable temperatures, sensible schedules and low flow temperatures where the system allows.
What if you find a fault rather than a settings issue?
If there is a mechanical or control fault, we will explain what we have found and what it means for performance. You will receive clear options for repair or further investigation before any additional work goes ahead.
How quickly will I notice a difference?
Some changes are noticeable the same day, such as steadier room temperatures and quieter operation. Efficiency improvements are usually clearer over the next few weeks as the system runs through different weather conditions.
