Don’t Switch the Heat Pump Off Completely
Unlike a gas boiler, switching a heat pump off completely during winter risks frost damage to the property and makes the reheat inefficient. Use holiday/frost protection mode instead.
Holiday Mode Settings
- Set the controller to holiday or away mode
- Target temperature: 12–15°C (frost protection, not zero heating)
- Hot water cylinder: reduce to minimum or switch to once-a-week legionella cycle only
Coming Home
Set the heat pump to resume normal operation a few hours before you return — heat pumps take longer than gas boilers to bring a cool house back to comfort temperature.
