- Try to avoid setting your heater above 21°C. If your unit is not heating your room to the required temperature, you may have a heater that is too small for the area you are trying to heat.
- Use the correct size heater for the room. Overheating wastes energy, while small heaters on a maximum setting will struggle to heat your room.
- To prevent drafts and heat loss, close windows and doors, and seal gaps with weather stripping.
- Heat or cool only those rooms that are being used.
- Turn your heater or cooler off overnight if possible.
- Carpet on wooden floors minimises heat loss.
- Use timers to make sure your heating or cooling turns on and off only when you need it.
- Block off any chimneys that are unused or install dampers to stop draughts and prevent heat loss.
- Place draft stoppers under door cracks or use a rolled up towel as an alternative.
- Remember to close your curtains to keep the heat in on cool nights, and to keep your home cool on hot days.
- Close doors to rooms that arent being used. This will ensure the heating or cooling is staying where is most needed.
- If you have ceiling fans in rooms that have high or cathedral ceilings. The fan should be running at its lowest speed to slowly push the air where it is needed.
- Outdoor shading of windows in summer will help to cool the room.
Heat pump efficiency
- Make sure the heat pump is the right size for your space. If it is too small or too large it may not heat the space effectively.
- Make sure the airflow around the unit isn’t obstructed, as this will affect efficiency and the operation of your heat pump, this is for both the indoor and outdoor units.
- The temperature of a heated room in winter should be between 18–21°C.
- The temperature of a cooled room in summer should be about 23–26°C (the humidity indoors will be low, so it will feel cooler).
- When using a heat pump, keep windows and doors closed and close window coverings on hot summer days and cold winter nights.
- Don’t try to heat the whole house with single room heat pumps.
- If the machine has adjustable louvres, adjust them towards the ceiling when cooling, and towards the floor when heating (cool air falls, hot air rises).
- Follow the manufacturer’s instructions for filter cleaning, but as a rule cleaning should be done at least once a week. Since the filters are cleaning the air by removing dust and pollen, the filters will accumulate dust build up. If this dust is not removed the heat pump will work inefficiently.
- Don’t have furniture or stand in front of your heat pump, this may disrupt the air flow and temperature of the room.
Should a heat pump be run overnight?
- All heat pumps operate differently and operational efficiency is dependent on a variety of factors including brand, age, wattage etc.
- For a more accurate assessment of your heat pump, and how to operate it for maximum efficiency, you should refer to the operating manual, or obtain advice from your heat pump specialist or electrician.
- Until you get the right advice – a heat pump that is switched on will always use more energy than one that is switched off.
