Getting the best from your heat pump
Heat pumps are the most efficient way of heating with electricity, but some are much more efficient than others. The more Energy Rating stars, the more energy-efficient. And some struggle in very cold conditions, so it’s worth asking which option is best, and what size is needed for the room to be heated.
In any event, start by insulating (which will make heating and cooling your home cheaper). The look for a quality brand with at least a five-year warranty on parts and labour, and make sure it’s the right size for the room.
Check the installer complies with the EECA guide. Correct location and installation is essential for optimum performance and for avoiding draughts and noise nuisance.
Make sure it’s right for your climate and environment. In coastal areas heat pumps need suitable protection against corrosion.
Only heat when you need it — don’t leave it on all day if you’re not there. Use the timer to turn it on shortly before you get home, and turn it off when you don’t need it. And only heat the space you’re actually using; shut doors and curtains to keep the heat in.
Set the thermostat to a healthy temperature — aim for 18-20 degrees Celsius. High thermostat settings equal high electricity use, while inadequate heating can lead to mould and dampness.
Using the auto mode has the pump trying to maintain the set temperature by constantly changing between heating and cooling, as the room temperature fluctuates. This can waste a lot of energy.
Clean the filter regularly, as per the manufacturer’s instructions.
