Do you leave your heatpump on all day?

As tempting as it is to leave your heatpump on read the article from stuff.co.nz below to find out more about heating your home

As the weather gets colder, it might be tempting to leave your heat pump on all day. But relying on this heating method is likely to mean unnecessarily high power bills. 

While lots of people believed leaving a heat pump on all the time was economically efficient, Energywise technical expert Christian Hoerning said switching your heat pump off while you were at work could slash "roughly $50 to $100 a month" from a power bill, depending on the size of the heat pump and the size of the space it needed to heat. 

"You should only heat your home when you need it," Hoerning said. "Don't leave your heat pump on all day if you're not there. You can set the timer to turn the unit on half an hour or so before you get home or before you get up in the morning." 

Hoerning said heat pumps are the most efficient way of using electricity to heat your home, but there are many ways people could use them more efficiently. 

‚ÄčINSULATE FIRST

By making sure your home is properly insulated, your heat pump won't have to work as hard. 

"If your ceiling and floor are adequately insulated you'll be able to buy a smaller heat pump and your home will be cheaper to heat and cool effectively. If you already have insulation, it pays to get it checked by a professional every few years to ensure there are no gaps and it isn't too thin." 

SIZE MATTERS

It's important to make sure your heat pump was right size for the room you want it to heat.

"If it's too small, it may cost you more to run and will struggle to provide enough heat when you most need it," Hoerning said. "You should also choose a heat pump with a high energy efficiency rating."

SET THE THERMOSTAT TO A HEALTHY TEMPERATURE

Hoerning suggested setting the thermostat between 18ºC to 20ºC.

"Setting the thermostat to the maximum level will cause high electricity use and could cancel out any other measure you've put in place to make the system more efficient."

CONSIDER YOUR CLIMATE

Some heat pumps struggle to perform when the outside temperatures are just above freezing point.

"As the temperature drops, so does the performance of many heat pumps," Energywise said on its website. "If you live in a cooler climate, ask your supplier if the heat pump you're looking at performs well and efficiently at cooler temperatures, and get it sized for the room you want to heat."
