Heat pump tips

Central Leader - - & LIFESTYLE LEISURE -

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.’’
