Should you turn your heat pump off at night?

The answer depends on your specific circumstances and preferences. While turning it off can save energy in some cases, it’s often more efficient to keep it running at a lower setting. We explain how you can determine if it makes sense for your case.

Night-time energy optimisation

When turning off your heat pump at night is useful.

Managing your heat pump's operation can lead to energy savings, especially when you consider turning your heat pump off at night. Ultimately, saving you money. This strategy is useful for reducing unnecessary energy consumption and optimising efficiency.

But turning off your heat pump at night to save money, is only useful if the energy consumed to heat up the house again in the morning is less than the energy saved in the night. This depends on factors like insulation - similar for all heatings and night set-back. Setting up a heat pump night set-back ensures your system runs only when needed, maintaining comfort without wasting power.

You can read our detailed guide on night set-back to get more insights in this concept.

An additional way of saving energy is to only turn your heat pump off for hot water during the night. This can help conserve energy further.

The case on keeping it on

Alternative: benefits of keeping your heat pump running all night long.

While turning off your heat pump at night can save energy in some scenarios, it’s mostly not the best approach. Here’s why you might want to keep it running:
  • Maintaining comfort

    Heat pumps maintain a consistent temperature throughout your home. Turning them off at night can lead to significant temperature drops, making your home uncomfortable. You might wake up to a cold house.

  • Enabling energy efficiency

    Our modern heat pumps are highly efficient and designed to run continuously. Turning them off and on can actually use more energy than keeping them running at a lower setting.

  • Protecting your home

    In extremely cold weather, turning off your heat pump can lead to frozen pipes and other issues. With our current system control frost-protection is activated during night set-back. But nevertheless, it is important to understand that there could be a risk.

  • Protecting health considerations

    A consistent, comfortable indoor room temperature is crucial for health and well-being. Keeping your heat pump running can help maintain a healthy living environment.

The myth of nightly heat pump noise is already debunked.

The times of loud heat pumps are long over. The noise of our modern heat pumps are similar in sound to a microwave.

Our ranks among the quietest on the market, with a sound power as low as 54dB(A) at three meters.

Therefore, an air source heat pump won't disturb your sleep. There is also a silent mode which can be activated at nighttime to reduce sound emissions.

Comfort and energy efficiency

Useful or not? It's more about the balance.

There's a lot more what you can do to ensure your heat pump saves energy. The key to managing your heat pump effectively lies in finding the right balance between comfort and energy efficiency. Here are some tips to help you achieve this:
  • Set a comfortable night-time temperatureInstead of turning your heat pump off completely, set it to a lower temperature at night via your control. This will save energy while ensuring your home remains comfortable.
  • Use heating controls wiselyTake advantage of programmable and smart thermostats to optimise your heating schedule. Set the temperature to lower when you’re asleep or away from home and raise it when you need warmth.Our heat pump controls portfolio

The ideal time

Perfect times to switch off your heat pump besides the night.

Turning your heat pump off at night can seem like a straightforward way to save energy. After all, if the heat pump isn’t running, it isn’t consuming electricity, right? Here are a few scenarios where this approach might also make sense:
  • Mild temperatures

    If you live in an area where night-time temperatures remain mild, turning off your heat pump can be a viable option. Your home may retain enough warmth from the day to keep you comfortable temperature through the night without additional heating.

  • Short holidays

    If you’re away from home for just a night or two, switching off the heat pump can save energy without significantly impacting your comfort when you return.

  • Using alternative heating

    If you have alternative heating sources, like a wood-burning stove or electric blankets, you might find it practical to turn off the heat pump at night and rely on these alternatives.

  • Eco-friendly choice

    Reducing your heat pump's runtime at night lowers your carbon footprint, contributing to a more sustainable lifestyle.
