All heat pump guides in one place

Common heat pump problems — high consumption, short cycling, lukewarm water — with likely causes and checks.

• The heat pump uses too much electricity
• The heat pump starts too often (short cycling)
• Hot water is lukewarm or runs out quickly
• Some radiators or underfloor loops don't heat up
• The electric backup heater runs too often
• The outdoor unit defrosts too often
• Room temperature fluctuates during the day

Step-by-step guides for optimising the heating curve, flow temperature, ΔT and hot water settings.

• Setting up the heating curve step by step
• Lowering flow temperature safely
• Setting up domestic hot water economically
• Tuning ΔT and flow rate
• Balancing radiators and underfloor heating
• Night setback — when it works

How to reduce a heat-pump home's electricity use: night tariffs, ventilation, building envelope and consumption tracking.

• Night tariffs and the heat pump — how to benefit
• Tracking and comparing electricity consumption
• Ventilation and heat recovery in heating cost
• The building envelope: where heat actually escapes
• Smart use of an air-to-air heat pump
