How to reduce heat pump consumption: 10 practical tips

Heat pump consumption can be influenced considerably by settings and maintenance – not just by the choice of unit. Here are ten steps that help, in order of greatest effect.

1. The lowest possible heating water temperature

The water temperature has the greatest effect on efficiency. Set the heating curve so that the water is only as warm as the house needs – Weather-compensated heat pump control: how to set the heating curve.

2. Stable operation instead of large setbacks

Especially with underfloor heating, it is better to keep a stable temperature than to cool the house significantly overnight and reheat it in the morning.

3. Open thermostatic heads

If the heads restrict the flow unnecessarily, the heat pump has to raise the water temperature. Leave the heads open in the main rooms and control the temperature with the controls.

4. A sensible hot water temperature

Each extra degree in the tank increases consumption – Hot water heating with a heat pump: tank, temperature and savings.

5. Limit the electric backup heater

Check when and how often the backup electric heater runs – A heat pump and a backup heat source: fireplace, boiler or electricity.

6. A clear outdoor unit

Leaves, snow and objects around the unit impair airflow and efficiency.

7. Regular servicing

The technician checks the pressure, filters, venting and settings – Heat pump servicing: what it includes and how often.

8. Ventilating sensibly

Short, intensive ventilation instead of windows left ajar for a long time. In modern houses, heat recovery ventilation helps – A heat pump and heat recovery ventilation: how they work together.

9. A favourable electricity tariff

Check with your supplier and distributor whether you have a suitable tariff for a household with a heat pump – Heat pump electrical connection: breaker, supply and tariff.

10. Your own electricity from photovoltaics

You can move water heating and cooling to the hours of production – A heat pump and photovoltaics: why it is worth combining them.
