Heat-pump controls & optimisation

Get more from the heat pump you already have.

If your home feels wrong or electricity use seems high, FLO can review the settings and system behaviour before recommending changes.

Tell us what is happening with your system. FLO will get back to you about the next step.

The answer you need

Can better settings improve a heat pump without changing the equipment?

Often, but only after checking the system and building. Weather compensation, schedules, set points and zone behaviour should be adjusted from evidence and then monitored, not changed repeatedly by guesswork.

The property-specific checks

How will FLO find the problem?

We use these details to work out what is practical, what needs more investigation and what the next step should be.

01

Comfort pattern

Record room temperatures and complaints against time and outdoor conditions.

02

Control logic

Review weather curve, schedules, thermostats, zones and hot-water priority together.

03

System response

Check flow temperatures, run time, cycling and backup heat before optimising.

The next step with FLO

Tell us what is happening. We'll work out what to check.

Describe the fault or performance issue first. FLO will discuss the appropriate checks and any proposed work with you before you decide.

Good to know

Questions you may have.

Should a heat pump run for long periods?+

Long steady operation can be normal. The useful question is whether it maintains comfort efficiently without excessive cycling or backup heat.

Should I turn it off overnight?+

The best schedule depends on heat loss, emitter response, tariff and comfort. Large temperature setbacks can create inefficient recovery for some systems.

How long should changes be monitored?+

Allow enough time and comparable weather to see a pattern. Record one controlled change at a time wherever practical.

What might change the recommendation?+

Controls cannot compensate for an undersized emitter, hydraulic fault or unsuitable system design. Those findings should lead to corrective work, not increasingly extreme settings.
