Australia's outdoor living culture does not stop when the temperature drops. A well-designed patio, deck, or garden space is a genuine extension of the home, and the investment in outdoor furniture, landscaping, and lighting loses its return the moment the evenings get cold and everyone moves inside. Outdoor heating extends the usable season of these spaces, sometimes by months, and the right product matched to the right space makes the difference between a heater that works and one that runs constantly without making anyone comfortable.
This guide covers how outdoor heating works, the main product categories, how to choose the right type for your space, and what Vent Experts currently has available.
Quick Insights: Outdoor Patio Heating for Australian Homes
✓ Purpose-built for outdoor use: Outdoor heaters are designed to extend the use of patios, decks, gardens, and alfresco areas during colder months.
✓ Radiant beats convective outdoors: Radiant heaters are generally more effective outdoors because they warm people and surfaces directly instead of trying to heat the surrounding air.
✓ Electric radiant is the practical default: Electric radiant heaters offer instant heat, flexible mounting options, and no fuel management, making them practical for most Australian homes.
✓ IP ratings matter outside: Higher IP ratings provide better protection against moisture and weather exposure — a minimum of IP44 for covered areas, IP65 for more exposed positions.
✓ Gas suits larger open areas: Gas and natural gas heaters can suit larger or open areas but require consideration of wind, fuel, ventilation, and clearance requirements.
✓ The Ventair Solstice covers up to 40 m²: The Ventair Solstice 2000W carries an IP65 rating and an effective heating area of approximately 20–40 square metres.
✓ Match heater to space: Choose outdoor heating based on space size, coverage, ceiling height, wind exposure, mounting position, and climate zone.
✓ Licensed electrician required: Outdoor electric heaters must be installed by a licensed electrician and comply with AS/NZS 3000.
How Outdoor Heating Works
Outdoor heaters work on one of two principles: convective heating, which warms the air, or radiant heating, which warms people and objects directly without heating the air between them.
In an outdoor environment, convective heating is largely ineffective. Warm air disperses into the atmosphere immediately and the space never reaches a comfortable temperature regardless of how much energy is put into it. This is why outdoor spaces feel cold even on still nights despite ambient temperature being manageable indoors.
Why Radiant Is the Right Technology for Outdoors
Radiant heating transfers energy directly to people and surfaces in its path, the same way sunlight warms you on a cold day. The air temperature is irrelevant to the comfort of people sitting in the heater's radiant range. This is why radiant heaters are the correct technology for outdoor spaces, and why wattage output needs to be matched to the area being heated rather than simply choosing the largest available option.
Types of Outdoor Heaters
Electric Radiant Heaters
The most versatile category for Australian residential outdoor use. Available in wall-mounted, ceiling-mounted, and freestanding configurations, operating on standard domestic power with no fuel management and no emissions. Instant heat on switching on, with no warm-up period required.
- Best for: Covered patios, verandas, and alfresco dining areas
- Mounting: Wall, ceiling, or freestanding
- IP requirement: Minimum IP44 for covered areas; IP65 for exposed positions
- Fuel: Standard domestic power; no bottles or gas lines
Gas Patio Heaters
The tall freestanding units familiar from pub beer gardens and restaurant outdoor areas. Operate on LPG bottles, require no fixed installation, and can be moved wherever the warmth is needed. Practical limitations include wind sensitivity, bottle management, and minimum overhead clearance requirements.
- Best for: Large open outdoor areas where electric installation is impractical
- Clearance: Minimum 1 metre overhead clearance from heater head to any structure
- Limitation: Not suitable for covered patios with limited ceiling height
- Fuel: LPG bottles; requires ongoing management and replacement
Natural Gas Outdoor Heaters
Connect to the home's gas supply rather than LPG bottles, eliminating bottle management and replacement costs. Lower ongoing operating cost than LPG and significantly more convenient for regular outdoor entertaining use. Installation requires a licensed gas fitter.
- Best for: Homes with existing gas supply and frequent outdoor entertaining
- Installation: Licensed gas fitter required to run supply and connect
- Running cost: Lower than LPG; no bottle management
- Limitation: Fixed installation; cannot be relocated
Infrared Heating Panels
A flat, low-profile alternative to conventional outdoor heater formats. Available in ceiling and wall-mount configurations, produce no visible glow, and integrate into outdoor structures more discreetly than standard heater units. Radiant output is comparable to conventional electric units at equivalent wattage.
- Best for: Contemporary outdoor spaces where aesthetics matter
- Mounting: Ceiling or wall fixed
- Appearance: No visible glow; blends with structure
- Output: Equivalent to conventional electric radiant at same wattage

The Ventair Solstice: Vent Experts' Featured Outdoor Heater
The primary outdoor heater available at Vent Experts is the Ventair Solstice Infrared Outdoor Heater at $609.95. The IP65 weather rating makes it one of the more robustly weather-resistant options in its category, suitable for covered outdoor areas including patios, pergolas, and alfresco dining spaces.
✓ What Works Well
- IP65 rating exceeds the IP55 minimum most covered outdoor installations require
- Wall or ceiling mountable; flexible across different outdoor configurations
- Remote control with three heat settings reduces energy waste in milder conditions

Matching the Heater to the Space
Covered Patios and Verandas
The most favourable outdoor heating environment. Apply 1–1.5 kW per m² in temperate climates (NSW, QLD); 1.5–2 kW per m² in colder southern climates (VIC, TAS, ACT). A single Ventair Solstice at 2,000W comfortably covers up to 20 m² in temperate conditions. Ceiling height matters, a heater at 2.4 m delivers more effective warmth at seated level than the same unit at 3.5 m.
Open Decks and Garden Areas
A more demanding environment, radiant heat disperses more rapidly without a reflective overhead surface, and even low wind speeds significantly reduce effective warmth. Wind breaks, whether structural or through planting, substantially improve heater performance. Reducing wind speed at the occupied zone by half more than doubles the effective warmth from the same wattage output.
Commercial Alfresco Areas
Higher traffic, longer operating hours, and greater heating demands than residential applications. Multiple Ventair Solstice units positioned to create overlapping heating zones cover larger commercial alfresco areas more evenly than spacing fewer, higher-wattage units further apart.
💡 Sizing Rule of Thumb
For a covered patio of six to ten square metres, the Solstice's three heat settings allow the unit to run at a lower level without waste. For a very large alfresco area above 40 m², two units positioned to create overlapping heating zones produce more even warmth than a single unit trying to stretch its range.

Year-Round Outdoor Entertaining Across Australia
Australia's climate varies enough across regions that year-round outdoor entertaining has different requirements by state.
| Region | Heating Season | Heating Demand | Recommended Capacity |
|---|---|---|---|
| QLD / NT | June–August (dry season) | Low–moderate | 1 kW per m² covered area |
| NSW | May–September | Moderate | 1–1.5 kW per m² |
| VIC | April–October | Moderate–high | 1.5–2 kW per m² |
| SA / WA south | April–October | High | 1.5–2 kW per m² |
| TAS | March–November | High | 2 kW per m² minimum |
Installation Considerations
Electric outdoor heaters installed in covered areas require electrical installation by a licensed electrician. The power supply needs to be rated for the heater's current draw, and outdoor-rated wiring and weatherproof fittings are required throughout. Wiring must comply with Australian Standard AS/NZS 3000.
Installation Checklist
- Licensed electrician: All fixed outdoor electrical installations must be completed by a licensed electrician — this includes supply wiring, weatherproof fittings, and circuit protection.
- Structural fixing: For ceiling-mounted units, the structural fixing must be rated for the heater's weight. Confirm with your installer before specifying a mounting point.
- Wiring capacity: Higher wattage units draw more current. Confirm the circuit can safely support the heater's load before installation proceeds.
- Outdoor-rated fittings throughout: Conduit, junction boxes, and switch fittings used outdoors must carry appropriate weatherproof ratings.
- Minimum clearances: Maintain minimum clearances from combustible materials as specified in the product documentation. Confirm with your electrician before finalising the mounting position.
- Test all functions post-installation: Verify heat output, remote control operation, and timer function immediately after installation.
⚠ AS/NZS 3000 Applies to Outdoor Installations
Outdoor electrical work is not less regulated than indoor work, in many respects the requirements are more specific because of the exposure to weather. Outdoor-rated wiring, weatherproof fittings, and correct IP ratings for the installation environment are all mandatory under AS/NZS 3000. DIY electrical work is illegal in Australia regardless of whether the installation is indoors or outdoors.
Extend Your Outdoor Season Year Round
The right outdoor heater matched to your space means your patio, deck, or alfresco area earns its keep through winter instead of sitting empty for four months of the year.

Frequently Asked Questions
Electric radiant heaters in ceiling or wall-mount configurations are the most practical choice for covered patios. They require no fuel management, produce instant heat on switching on, and are available in IP-rated variants suited to outdoor installation. The Ventair Solstice at Vent Experts covers 20–40 square metres at 2,000W with an IP65 rating, making it well suited to most residential covered patio applications without requiring LPG bottles or a gas line.
Heaters with an appropriate IP rating can be used in covered outdoor areas exposed to rain splash and spray. IP44 is the minimum practical rating for a covered outdoor area. Fully exposed installations, or covered areas subject to heavier weather exposure including driving rain, require IP65 or higher. The Ventair Solstice carries an IP65 rating, which covers most covered outdoor installation scenarios in Australian conditions. The IP rating of any outdoor heater should always be confirmed against its specific installation position before purchase.
A 2,000W electric heater running at full output costs approximately 60 cents per hour at a rate of 30 cents per kilowatt-hour, a typical residential rate across most Australian states. The Ventair Solstice's three heat settings allow operation at lower output levels when full wattage is not required, which reduces running cost in milder conditions. The built-in timer function prevents the unit running beyond the period it is actually needed, so you are not paying to heat an empty patio after guests have left.
The Ventair Solstice covers an effective heating area of 20–40 square metres depending on conditions, ceiling height, heat setting in use, and wind exposure. In a covered patio with a standard ceiling height and limited wind exposure, 20–25 square metres at full output is a realistic working figure for consistently comfortable warmth at seated level. For larger areas, two units positioned to create overlapping heating zones produce more even warmth than stretching a single unit across a wider space than its rated coverage.
The Ventair Solstice Infrared Outdoor Heater is available through Vent Experts at ventexperts.com.au for $609.95.
