Heat pump optimisation guides
Step-by-step guides for optimising the heating curve, flow temperature, ΔT and hot water settings.
- Setting up the heating curve step by stepHow to tune the heating curve and offset safely: measure, change one step at a time, observe for a week. A practical guide.
- Lowering flow temperature safelyEvery degree lower in flow temperature means roughly 2–3% less consumption. How to find the lowest temperature that still works.
- Setting up domestic hot water economicallyTank temperature, legionella cycle and timing. How to reduce hot water cost without sacrificing hygiene.
- Tuning ΔT and flow rateThe flow/return temperature gap (ΔT) shows the hydraulic system's condition. What values are healthy and what to do about deviations.
- Balancing radiators and underfloor heatingHow to distribute heat evenly around the house: flow meters, thermostatic valves and the order to follow.
- Night setback — when it worksDoes night temperature setback save with a heat pump? The difference between underfloor heating and radiators, practical advice.
