How Efficient Are Indoor Heaters?

Indoor Heaters

There are a few ways we try to keep our houses toasty when it gets cold outside.  Gas heaters, electric ones, and reverse cycle air-con all do the trick, but it pays to consider their efficiency with rising power bills.  Gas heaters in Sydney are pretty popular.  They're known for working well and being affordable, especially for big spaces. The way they work - they burn natural gas or LPG to heat this heat exchanger, which blows hot air around your room.  Nice and warm! Electric heaters are dead easy to use but might not be as efficient as gas ones, particularly in bigger areas. Reverse cycle air con is efficient and can heat and cool a room.  So it's nice and flexible. 

With rising costs and wanting to help the environment, efficiency is key when picking which heater to use.  The different types have different efficiency ratings to check out.  It's also good to consider ways to use heaters more efficiently around the home—little things to save money and emissions.

Factors Affecting Efficiency

A few things can impact how well your indoor heater works.

Size of the room

If your heater is too small for the area, it has to work extra hard to keep things cosy. Proper insulation helps; otherwise, you'll lose heat and waste money.

Setting on your heater

Thermostat settings also play a role because setting them too high when you don't need them just burns energy for no reason. The actual heater age and how well it's maintained also matter.  

Check out the ratings

Those energy efficiency star ratings are useful when getting a heater.  More stars means it uses less energy, which is good for your wallet and the planet.  Here in Australia, heaters must have a label to compare.  It's worth looking at the upfront cost and potential savings from lower electricity bills. 

Benefits of Efficient heaters 

Picking an effective indoor heater has a few perks. It can seriously cut energy costs, especially in chillier months when we blast the heat more. Efficient models also have less impact on the planet since they consume less power and release fewer emissions. This shrinks your carbon footprint and helps you achieve a greener future. Lastly, efficient heaters make rooms more comfy with steady, even warmth, so your space feels cosier.   

Tips to Boost Your Heater’s Efficiency

Properly installing and correctly sizing your heater is key. 

You want it positioned to spread warmth evenly throughout the room. An oversized heater is overkill and uses more energy than it needs to. On the other hand, one that's too small may not cut it when the temperatures drop.

Regular maintenance helps with efficiency.  

Replacing filters and clearing out ducts improves airflow. Smart thermostats are also pretty slick because they automatically adjust the temperature at different times of the day.  

Try to contain the warmth.

Doing small things like closing doors to unused rooms or putting up curtains traps heat better, so your heater doesn't have to work as hard.

Little tweaks like these can optimise your heater efficiency!


Heaters inside the house make your home feel nice and cosy during the cold months. Picking one that uses energy efficiently can save you money on bills, help the environment, and just make your rooms more pleasant to hang out in.
