Electric heaters

- Good for: heating modest spaces, or individual people.
- Read our electric heater reviews to find which models we recommend.
Gas heaters
A gas heater can be very efficient and good value for money, and some people prefer the feel of gas heating over electrical heaters and air conditioners. Gas heaters can run from reticulated natural gas (gas connected to your abode) or bottled LPG, simply you need to make certain you have the right model for the type of gas you accept available, every bit a heater designed for natural gas won't piece of work with LPG, and vice versa.
Gas heating produces minor amounts of waste products: these include carbon monoxide, which is dangerous, and water vapour, which tin can lead to condensation and mould bug. They besides release nitrous dioxide and fine particles, which several studies have shown are a factor contributing to childhood asthma and other respiratory health issues. Flued gas heaters and central ducted gas heating may be less likely to have this risk as they vent near of the waste outside, simply they can still release a minor amount of emissions into the indoor air, so the take chances is not nada for these types either.
- Flued heatersdirect their fumes outside through a flue, or pipe, and are generally more expensive to purchase and install. This removes the waste product products such equally carbon monoxide and water vapour from the home, which is safer, only tin as well create a small amount of heat loss, reducing the efficiency.
- Portable, or unflued heatersmiscarry theirwaste products into the room being heated. Australian standards and regulations strictly limit the amount of emissions allowed, but notwithstanding yous need to keep the room ventilated.
- Gas heaters need to be professionally serviced every few years to ensure they're operating safely and effectively.
- NEVER apply an outdoor gas heater for indoor heating! They don't have the aforementioned emission standards as indoor gas heaters and tin give off a dangerous amount of carbon monoxide and other gases if left running indoors for several hours. The same applies for your kitchen'southward gas cooktop or oven.
- If you have a gas heater of whatever blazon (whether flued, portable unflued, or ducted central heating) and so make sure to install a carbon monoxide alarm too – they're readily bachelor from hardware stores. This could save your life if the heater develops a error and starts putting out dangerous amounts of this mortiferous gas.
- Bank check our gas heater ownership guide for more details.
If you're going to leave a heater on all day, a gas heater may exist cheaper to run than a portable electric heater, though probably not equally cheap as a opposite-cycle air conditioner. Still, average national gas prices have risen in recent years and solar ability is making electricity much cheaper in many homes – information technology'due south not a given that gas heating is always cheaper than using electricity. Gas is besides a fossil fuel, a cistron to consider if y'all're trying to go green.
- Good for: heating smaller to medium-sized spaces.
- See our gas heater reviews if you're fix to purchase.
Reverse-cycle air conditioners
These are very effective for heating individual rooms and big spaces such as an open-programme living area. And they're much more economical than trying to heat the aforementioned space with portable electric heaters, because for every unit of electricity they eat, they can put out 3 or more units of oestrus, due to the heat pump technology they utilize. The downside of a contrary-wheel air conditioner is that it'due south more expensive to buy and install than a portable electric heater. Check our air conditioner buying guide for more details.
- Skilful for: small models are skilful for a unmarried room, while larger models can heat bigger spaces such as open-program living areas.
- Nosotros rate small, medium and large units in our reverse-cycle air conditioner reviews.
How much does it cost to heat your home?
The costs below are based on using the heater in a moderate climate, for 6 hours a solar day over 12 weeks in winter. They're indicative costs only; your costs will depend on your home, your local climate and the prices you pay for electricity and gas. For example, for a dwelling with its own solar console arrangement, running an electric heater or air conditioner in daytime can be significantly cheaper than running a gas heater.
| Suitable heater type | Running cost / 500 hours |
|---|---|
| Small gas (1.5kW) | |
| Portable electric heater (2.4kW) | |
| Pocket-size reverse-cycle air con (3.5kW) | |
| Suitable heater type | Running cost / 500 hours |
|---|---|
| Medium gas (3.5kW) | |
| Medium contrary-bicycle air con (6.0kW) | |
| Suitable heater type | Running cost / 500 hours |
|---|---|
| Large gas (7kW) | |
| Large reverse-cycle air con (8.5kW) | |
How can yous make heating your home cheaper?
Before buying a heater
Make your home equally thermally efficient as you tin to proceed the rut inside in winter and exterior in summertime.
- Eliminate draughts. Make sure windows and doors are well sealed. Use draught excluders and door snakes if needed and close off any rooms you don't demand to heat. But remember that if you're using a portable gas heater, you need some ventilation.
- Insulate the ceiling. Ideally, walls and floors should also be insulated. Rugs can provide some useful insulation on a hard floor.
- Curtains and blinds will aid keep the warmth from escaping through drinking glass windows and doors.
Programme ahead
Earlier the winter chill hits, retrieve about what sort of heating y'all're going to demand.
- If you know you're going to need a new electric or gas heater, try to beat the rush and buy one ahead of winter (which is not always like shooting fish in a barrel, as stores frequently don't stock many heaters until the common cold weather arrives). Expect online for cheap 2nd-mitt models, but these might need a service to ensure they piece of work safely. Alternatively, pick one upward cheap in a clearance sale afterward wintertime and store it for adjacent year.
- Clean your reverse-cycle air conditioner's filters to keep it running effectively, and consider whether information technology needs a service.
- If y'all're looking at having a new air conditioner or flued gas heater installed, get this done well alee of the peak common cold flavour; don't wait until the installers are decorated. You might choice up an off-season bargain this style.
The correct sized heater
Make sure you become the right size of heater for the space yous're looking to heat – encounter in a higher place for our size tips for each heater type.
- Room heating calculators can be found online; try searching for room heater size.
- There are several factors to consider when choosing your heater'due south capacity: the climate you live in, the floor area and ceiling meridian of the room, how much natural sunlight it receives, whether the room is carpeted, whether side by side rooms or floors above and beneath are heated, and of class the amount of other insulation.
As a general guide: for moderate climates, a well-insulated room of twenty square metres will probably need a 2000W electrical heater or a gas heater with six–8MJ input. The same room would need more heating if poorly insulated; even a 2400W electrical heater could struggle, and you could need at least a 10–12MJ gas heater. In common cold climates, you'll need more than heating power still.
How to keep it cheap
- Only use the heater when you actually need to. That sounds obvious, but it's easy to get into the habit of routinely switching the heater on when maybe just putting on a jumper is a better option.
- Don't oestrus rooms to tropical temperatures; for example, try 20 degrees instead of 23 degrees. Each degree less volition save about 10% on your energy apply.
- Only estrus the rooms you're actually using.
- Hot air rises to the ceiling, so if you lot have a ceiling fan with a opposite-direction option, consider using it at a low speed to aid circulate the hot air more evenly through the room without creating a down cakewalk.
Other heating options
Wood-burning stoves and fireplaces
Wood fires can give a cosy look and feel to a room on a cold dark. Modern slow-combustion wood-burning stoves can exist quite efficient too.
Firewood should be well seasoned (left to dry out for at least 2 summers) so you don't waste energy evaporating water by burning light-green forest. Hardwood contains more than energy than softwood, and burns longer and more steadily. Just it's likewise harder to light. Softwood tin can spit and spark in open fires.
Pros
- Wood is available most everywhere.
- Forest heating can exist very economical if y'all accept cheap or fifty-fifty free firewood (even so, bank check whether y'all need a permit to collect firewood from forests).
- If firewood is produced sustainably (by regrowing the corporeality that's used) and burned in a slow-combustion heater, it produces the least amount of CO2 of all the fuels in our comparison.
Cons
- You need somewhere to store wood in reasonable quantity.
-
If you're buying your firewood, information technology tin price several hundred dollars (or more) for a winter'due south worth of good firewood.
-
You have to load the heater or grate, start and maintain the fire and dispose of the ash.
- Autonomously from modern slow-combustion heaters, solid-fuel heaters are less energy-efficient than electrical and gas heating.
- They produce combustion gases and need a flue or chimney, which makes installation expensive.
- Not all the fume and other combustion products go upward the chimney; some will get into the indoor air and tin can exist a serious irritant for people with asthma and other respiratory conditions.
- The smoke from wood fires can be a major correspondent to outdoor air pollution.
Ethanol fireplaces
These use denatured ethanol (methylated spirits) which doesn't requite off dangerous fumes such as carbon monoxide when burned (though it does give off h2o vapour and carbon dioxide). So these burners don't need vents or flues, or a gas or electrical connectedness.
They're comparable in heating chapters and efficiency to an unflued gas heater, and typically cost a few hundred dollars. However, they're more than expensive to run – one litre of fuel, costing well-nigh $half-dozen, will requite roughly 90 minutes to two hours called-for on a loftier setting. The same corporeality of heating with gas would cost around 50c.
Decorative booze-fuelled burners were temporarily banned years ago post-obit a long listing of serious burn injuries and fire incidents, simply they tin at present be sold as long as they meet the specified decorative alcohol-fuelled device safety standard. Under this standard, table top burners (devices weighing less than 8kg or with a footprint less than 900cm2) are not allowed. Freestanding and fixed devices must pass a stability test, have a flame arrester or automated fuel pump system and be labelled with warnings almost refuelling hazards.
Many models have open flames, so you need to have the aforementioned intendance around them as with an open wood fireplace, and you lot too demand to be conscientious when handling the fuel. A number of people take been burned by them through mishandling, hence the ban and safety standard mentioned in a higher place.
Whole house heating
Hydronic
Hydronic heating works through heating water (or steam), piping it through the house into panel radiators and returning the water dorsum to the heating system to be reheated for the cycle to echo. Y'all tin likewise utilise this method to provide heating to in-floor systems.
The advantages: straight control of how much rut y'all desire to each room via the organization's panel radiators, which are quiet and unobtrusive. It'south a relatively quick mode of heating, depression maintenance and it's well tested, having been used in many countries for effectually a century.
The disadvantage is it'due south quite expensive to install; quotes tin can get-go at effectually $6000.
The heating supply is usually a boiler, fuelled past natural gas, LPG, electricity, or solid fuel. Wait for a low content boiler then it'south not wasting fuel, panels that heat up rapidly and can be controlled independently, and pipes that don't lose rut where they don't need to.
Electrical
Ducted reverse-wheel ac
Ducted air conditioners consist of a compressor (which can be installed outside or in the ceiling space, for example) and ducted outlets in the rooms you lot desire to heat or absurd. A good system can be very efficient, but installation can be plush, in the several thousands of dollars. Consider it if you're building or renovating a house.
Underfloor heating
For this type of heating, electric wiring or water pipes are installed into the concrete floor slab. The slab is heated, using cheap off-acme electricity or hot water (in which case you lot can utilize a gas heater to estrus the h2o if gas is bachelor). Information technology then releases the stored estrus during the mean solar day, in a like fashion to an off-elevation storage heater. The substantial structure piece of work required for this blazon of heating means information technology'due south more than appropriately installed when a house is being built.
Gas
Ducted gas key heating
This organization consists of a gas furnace (which can be installed exterior or underfloor) and ducting vents in the rooms y'all want to heat. A ducted system may work out cheaper to run than 2 gas space heaters, though installation costs are usually much higher.
Solid fuels
Typically a slow-combustion stove with rut shifters: the stove in one room is connected to a system of ducts and fans in the ceiling space that shift warm air to other rooms. This could be a good option if you have a big supply of cheap wood or other solid fuel, only the aforementioned negatives listed above for any woods-burning stove still apply.
