Common Heater Types To Buy
Heaters come in various configurations to suit different heating needs and room sizes. Electric heaters plug directly into standard power outlets, whilst gas heaters require connection to natural gas or bottled LPG. Below is a breakdown of the most common:
Convection heaters: Warm air circulates naturally through the room
Radiant heaters: Direct heat towards people and objects
Fan heaters: Blow warm air for quick temperature increases
Oil-filled column heaters: Retain heat longer after switching off
Panel heaters: Wall-mounted for permanent installation
Micathermic heaters: Combine radiant and convection heating
Reverse cycle air conditioners cool in summer and heat in winter. Electric fireplaces add ambience alongside warmth. Electric blankets provide targeted personal heating for bedtime comfort.
Room Size And Heater Capacity Requirements
Room heater capacity measures in watts or kilowatts, with higher wattage needed for larger spaces. A general guideline suggests 100 watts per square metre for well-insulated rooms with standard 2.4-metre ceilings. Poorly insulated rooms require approximately 150 watts per square metre.
Capacity by room size:
10-15 sqm (small bedrooms): 1000-1500 watts
20-25 sqm (medium living areas): 2000-2500 watts
30+ sqm (large open-plan spaces): 3000+ watts or multiple units
Ceiling height above 3 metres, large windows, and poor insulation all increase heating requirements. Our heater buying guide provides detailed calculations for specific room configurations.
Safety Features To Look For When Buying A Household Heater
Household heaters should include overheat protection that automatically switches off when internal temperatures exceed safe levels. Tip-over switches cut power immediately if a space heater falls, particularly important for portable models. Below are the common safety features to consider:
Cool-touch exteriors: Maintain lower surface temperatures during operation
Child locks: Disable controls to prevent temperature adjustments
Automatic shut-off timers: Prevent heaters running indefinitely
Enclosed heating elements: Reduce contact burn risks
Stable base design: Minimise tipping likelihood
Flame-failure devices: Shut off gas supply if pilot light extinguishes
Heaters carrying Australian safety certification marks meet local electrical and fire safety standards. Manufacturers specify minimum clearance distances from curtains, furniture and walls to prevent fire hazards.
Rinnai manufactures gas heaters known for efficient performance in Australian conditions. Dimplex specialises in electric heating including panel heaters and electric fireplaces. DeLonghi produces oil-filled column heaters with Italian design aesthetics.
Other leading brands:
Hisense: Competitively priced with modern features
Kelvinator: Options across various heating technologies
Panasonic: Reliable performance across price points
Sunbeam: Personal heating solutions and electric blankets
Our best heater for any room guide compares models across different categories.
Smart heaters connect to home Wi-Fi networks, allowing temperature control through smartphone applications. Remote operation lets you activate heating before arriving home. Voice control integration with Amazon Alexa or Google Assistant enables hands-free adjustments.
Other common features:
Weekly timers: Programme different schedules for weekdays and weekends
Occupancy sensors: Automatically reduce output when spaces remain empty
Geofencing: Activates heating when you approach home
Energy monitoring: Tracks electricity consumption in real-time
Digital thermostats: Precise temperature control compared to dial controls
Learning about energy efficient heating helps identify which smart features deliver genuine savings.
Most household heaters require minimal maintenance beyond regular dust removal. Fan heaters benefit from filter cleaning every few weeks during heavy use. Oil-filled column heaters contain sealed systems needing no servicing throughout their operational lifespan.
Maintenance schedules:
Weekly: Dust removal from vents and surfaces
Monthly: Filter cleaning for fan-forced models
Annually: Professional gas heater inspection and servicing
Pre-season: Full inspection before winter heating period
Portable heaters should have vents wiped with a soft cloth when unplugged and cool. Gas heaters require annual professional servicing to check burner operation and verify safe combustion. Our efficient home heating systems article covers long-term maintenance strategies.
Climate zones across Australia vary from tropical northern regions to cold inland locations. Mild coastal climates with minimum winter temperatures around 10°C generally manage with smaller capacity heaters. Alpine and inland regions experiencing frosts below 5°C benefit from higher-capacity permanent installations.
Climate-specific recommendations:
Tropical zones: Minimal heating needs, portable models sufficient
Temperate regions: Medium-capacity heaters for occasional cold periods
Cold climates: Permanent installations with 2000+ watt capacity
Alpine areas: Consider whole-home heating with reverse cycle systems
Humid climates favour heaters that don't add moisture to air, making fan heaters and radiant models preferable. Coastal regions with salt air should choose heaters with corrosion-resistant components. Professional installation services ensure permanent heaters operate safely and efficiently.
