Heat pump tips
Heat pumps need to be used in a smart way to make houses warm and healthy, the Energy Efficiency and Conservation Authority (EECA) says.
EECA ENERGYWISE technical expert Christian Hoerning says there are simple tricks to avoid wasting energy. He advises only heating the space you’re using and shutting doors and curtains to keep the heat in.
He says the next step is learning to use the timer feature.
‘‘Don’t leave your heat pump on all day if you’re not there. You can set the unit to turn on half an hour or so before you get home or before you get up in the morning.’’
Using the timer will also avoid the common mistake of coming into a cold house and cranking up the heat pump to its highest setting, he says.
‘‘Set the thermostat to a healthy temperature. Aim for a minimum of 18ºC while you are using a space and 16ºC in bedrooms overnight.’’
Cleaning the heat pump filters regularly will also mean the heat pump runs more efficiently
If you are considering buying a heat pump, look for the blue ENERGY STAR mark to identify superior energy efficiency. Like all heaters, heat pumps can use a lot of energy so it pays to get an efficient model.
‘‘Some heat pumps also ice up if the temperature falls to between 5 and 0°C. That’s why ENERGY STAR now includes a requirement that’s designed to ensure a correctly sized ENERGY STAR heat pump will perform efficiently in this temperature range.’’
