10 home heating mistakes costing you money

As temperatures fall and we crank up the heating, it pays to be clever with how you stay toasty warm. After all, whether you’re buying a new system or just running an older one, it’s easy to fall into traps and bad habits that can quickly burn a hole in your wallet over winter.

To stop that happening, CHOICE heating expert Chris Barnes reveals the common heating mistakes many of us make – plus smart tips to save you money.

1. Assuming expensive models are always the best

Ready for a burning-hot revelation? CHOICE product testing often reveals retail price isn’t the best indicator of performance. So splashing cash on a high-end heater or air con without doing your research could still leave you out in the cold.

Although CHOICE experts did test some heater models costing in the $400 to $500 range that they’d happily recommend, they also uncovered quite a few exxy units that disappointed.

Just as importantly, they found budget heaters for under $100 that were better than models costing hundreds of dollars more. So don’t assume that just because a heater is expensive or from a well-known brand that it’s going to give you the best value for money.

2. Buying a dud budget heater

Surprise, surprise! It’s not just expensive models that can disappoint – cheap ones can too, leaving you both frosty and frustrated.

Kmart Anko’s heaters, for example, have had the lowest test scores in the past two years. Their terrible 2020 model may have cost just $55, but it scored only 45 recent in CHOICE testing – the worst heater result we’ve seen since 2014.

But don’t be disheartened if you’re on a budget. Those same tests also uncovered some cheap gems that cost the same but performed a lot better.

3. Presuming all heaters cost the same to run

Don’t just look at the price tag when you buy. CHOICE testing reveals heaters can have vastly different running costs that will have an ongoing effect on your pocket.

In CHOICE’s analysis of more than 40 electric models, experts found heater running costs for winter can vary from $193 to $368, depending on the brand and design of heater (based on an estimated 500 hours of use and an electricity price of 30c/kWh).

4. Not using your ceiling fans’ reverse mode

Think ceiling fans are just for summer heatwaves? Think again.

Switch your fans to reverse or winter mode (clockwise) and use them in combination with your heating system. This will help distribute the hot air more evenly around the room(s) – and ensure it’s not just hanging around the ceiling where it’s no use to your cold tootsies.

CHOICE lab analysis shows that, used this way, your heater has to do far less work to maintain a constant temperature, which means lower power consumption and lower bills.

5. Not using your air conditioner for heating

If you’re wondering whether you should be using an electric heater or your air conditioning to warm your home this winter, CHOICE experts have you covered.

Although electric heaters are convenient and have cheaper upfront costs, reverse-cycle air conditioners are a more efficient heating option and can save you big bucks on your energy bills in the long run.

6. Constantly cranking up your air con temperature

The cost of using reverse-cycle air con to heat your home can range from $113 for a small unit up to $335 for a large one (based on an estimated 500 hours of use and an electricity price of 30c/kWh).

To give you optimal warmth for the cheapest price, CHOICE expert Chris Barnes says you should try to stick to a difference of about 8°C between the temperature on your reverse-cycle air conditioner and the outside temperature (easy enough in the more temperate parts of Australia).

Basically, the harder your air conditioner has to work to heat your room, the more electricity it’s going to use – and the more it will cost you. As a helpful rule of thumb, each degree warmer usually adds about 10 percent to the running cost of your air conditioner.

7. Neglecting your heater and air-con maintenance

Even heaters and air cons need a little love to work their very best. Regularly cleaning your air conditioner or heater means better energy efficiency and lower running costs.

This is because the more clogged the dust filters and the interior of the machine become, the harder it has to work (and the more energy it uses) to move the air and heat your home.

8. Drying washing on or in front of a heater

On a freezing night, it’s tempting to plonk yourself in front of your heater or pop the wet washing right in front of it, or even directly on it – but it will do your heating bill no favours.

Any obstruction will restrict or block the flow of hot air around your home. This means your heater will have to work harder and longer to get the temperature up.

9. Letting draughts in

Tracking down any draughts in your home, particularly around doors and windows, then sealing them up, will help keep your home warmer and save on energy bills. Likewise, keeping windows securely fastened or even locked can really help.

Cover gappy floorboards with rugs, close curtains and, if necessary, do a bit of simple DIY where the cold air is getting in. Use things such as silicone sealant, weather seal tape or draught strips from the hardware store to fill gaps in, or use an old-fashioned door snake to keep the cold out.

10. Ignoring insulation

When it comes to keeping all that lovely warm air inside your home, insulation is a no-brainer – especially as 25–35 percent of an uninsulated home’s warmth is lost through the roof in winter.

“Average households that install wall, floor and ceiling insulation can save hundreds of dollars on energy bills each year,” says Chris Barnes.

You can call in the professionals, but ceiling and underfloor insulation can often be done by a capable handyperson, too.
