Quick Answer: What You Need to Know
For the best balance of heating power, running cost, and convenience, choose a gas patio heater for large open areas or an electric infrared heater for covered patios and smaller zones. Gas models produce higher heat output (typically 10–13 kW) and warm people directly, while electric units offer instant operation, zero emissions, and lower ongoing expenses. Consider your local wind conditions, ceiling height, and whether you need portability. For permanent installations, wall-mounted or ceiling-mounted infrared panels save floor space and deliver consistent warmth without a bulky standing unit.
Practical Guide: Core Types of Outdoor Heaters
Standing Gas Patio Heaters
These tall, freestanding units are the most recognisable outdoor heaters. They run on LPG bottles, produce immediate radiant heat, and can cover a diameter of about 3–4 metres. Their main limitation is that heat disperses quickly in windy conditions, so you may need a windbreak or a more powerful model. Modern gas heaters include tilt switch safety mechanisms and piezo ignition, making them straightforward to operate.
Wall-Mounted Electric Infrared Heaters
Electric infrared panels mount flush against a wall or ceiling and emit directional heat that warms objects and people directly rather than the air. They work well under pergolas or eaves where weather exposure is limited. Operating costs are lower than gas because electricity is cheaper per unit of heat in New Zealand, and there is no need to refill fuel cylinders. Installation requires professional electrical wiring, but once set up they require minimal maintenance.
Tabletop Heaters and Portable Models
Smaller units designed for dining tables or small balconies typically run on a small gas canister or electricity. They are convenient for renters or people who want a temporary solution, but their heat output is limited—usually 2–4 kW—so they only warm a small zone directly above the table. If your space is larger than 10 square metres, a tabletop heater will likely leave you cold.
Comparison: Electric vs Gas vs Infrared
Choosing between these three primary technologies depends on your specific use-case, budget, and local climate. The table below summarises the most important distinctions to help you narrow down your options quickly.
| Feature | Electric Convection | Gas Radiant | Infrared Panel |
|---|---|---|---|
| Heat output (typical) | 2–3 kW | 10–13 kW | 1–2 kW per panel |
| Best for | Small covered areas | Large open patios | Permanent covered zones |
| Running cost (per hour) | $0.40–$0.70 | $1.50–$2.50 | $0.20–$0.40 |
| Installation | Plug and play | Gas bottle + regulator | Hardwired electrician |
| Wind resistance | Low | Medium | Medium (with good housing) |
| Maintenance | Minimal | Annual burner check | Clean panel surface |
Electric convection heaters are the cheapest upfront but struggle to warm large spaces. Gas models deliver powerful heat but involve ongoing fuel costs and cylinder swaps. Infrared panels excel in efficiency and low running expenses but require permanent installation. If you need to heat a semi-enclosed outdoor room where people sit close together, infrared provides the most comfort per dollar over time.
Features Table: Key Specifications to Compare
Once you settle on a heater type, comparing specific technical features ensures you pick a model that performs well in New Zealand conditions. Pay attention to the details in this table when reading product descriptions or visiting showrooms.
| Specification | What to Look For | Why It Matters |
|---|---|---|
| Heating area (square metres) | Minimum 20 m² for gas, 10 m² for infrared | Determines whether the unit can actually warm your space |
| Ignition type | Piezo or electronic push-button | Electric ignition is more reliable in windy conditions |
| Safety shut-off | Tip-over and oxygen depletion sensor | Essential for gas models to prevent accidents and carbon monoxide buildup |
| Material quality | Stainless steel or powder-coated aluminium | Resists rust and corrosion from coastal air in many NZ locations |
| Weight and portability | Under 25 kg for portable units | Crucial if you need to move the heater around the garden or store it seasonally |
Most manufacturers list these specs on the packaging or website, but retailers often skip them in the product description. When comparing two models, the one with a higher-grade stainless steel housing and a more robust safety system is almost always the better long-term investment. Never base your decision solely on the listed kW rating because heat distribution varies significantly between designs.
Checklist: Pre-Purchase Evaluation
Before you commit to a specific heater, run through this practical checklist to avoid costly mistakes. Each item addresses a real-world issue that first-time buyers often overlook.
- Measure your patio or deck area in square metres, including any overhead cover.
- Check the clearance height—gas heaters need at least 2 metres, infrared panels need 0.5 metres above people.
- Decide whether you want a fixed or portable unit based on whether you entertain in different spots.
- Confirm local council rules regarding gas bottle storage and placement near combustible materials.
- Review annual running costs by multiplying hourly consumption by your local electricity or LPG price.
- Inspect the warranty period and after-sales support available from the NZ distributor.
- Read owner reviews specifically about heat distribution, noise levels, and build quality after one year of use.
Taking ten minutes to complete this checklist can save you hundreds of dollars and the disappointment of a heater that underperforms. Many returns happen simply because people misjudged the space or the fuel type.
Expert Tips: Optimising Placement and Efficiency
Positioning for Maximum Heat
Place gas heaters in the centre of the seating area so the heat radiates outward in all directions. If the unit is against a wall, half the heat is wasted. For infrared panels, angle them downward at about 30 degrees toward the seating area to focus warmth on people rather than the ground. Reflective surfaces like light-coloured paving stones help bounce heat back into the zone.
Wind Management Strategies
New Zealand’s coastal and breezy conditions can steal heat from any outdoor heater. Use glass windbreaks, dense hedging, or retractable screens to create a sheltered pocket. Even a simple outdoor curtain on one side reduces heat loss by up to 40%. If your site is exceptionally exposed, consider a high-output gas model rated for windy environments.
Seasonal Storage and Maintenance
At the end of winter, clean the burner ports on gas heaters with a soft brush to remove spider webs and debris. Store electric units indoors or under a waterproof cover. For infrared panels, wipe the surface with a dry cloth to prevent dust buildup, which reduces efficiency. Proper care doubles the lifespan of most outdoor heating equipment.
Frequently Asked Questions
Can I use a gas heater under a covered patio?
Yes, but ensure the ceiling is at least 2.4 metres high and the area is well-ventilated. Never use a gas heater inside an enclosed room or under a low carport. A carbon monoxide detector is a wise addition if you frequently run the heater for long periods.
How much does it cost to run an electric patio heater for four hours?
A typical 2 kW electric heater running for four hours consumes about 8 kWh. At New Zealand’s average electricity rate of roughly 26 cents per kWh, that totals around $2.08 per session. This makes electric heaters significantly cheaper to operate than gas models over the same duration.
What is the most energy-efficient outdoor heater?
Infrared panel heaters are the most efficient because they heat objects directly without warming the air. They lose very little energy to convection or wind. For a permanent installation, infrared panels can reduce your heating cost by up to 50% compared to a gas unit, especially in sheltered patios.
Do outdoor heaters need to be cleaned regularly?
Yes, especially gas models. Dust, cobwebs, and grease can clog burner ports and reduce heat output. Clean the reflector and burner screen at least once a month during heavy use. Electric heaters usually only need the surface wiped down to maintain efficiency.
Can I leave my outdoor heater outside year-round?
Only if it is explicitly rated for outdoor storage with a high ingress protection (IP) rating and corrosion-proof materials. Most standard models will rust or degrade quickly if left uncovered through a New Zealand winter. A good quality waterproof cover is the simplest way to protect your investment regardless of the heater type.
Final Recommendations
Selecting the right outdoor heater comes down to matching the heat source to your space, budget, and typical weather. For covered patios in sheltered backyards, infrared panels offer the lowest running costs and a clean aesthetic. For large, open entertainments areas where you need intense heat on demand, a gas radiant heater remains the most powerful option. Whatever you choose, prioritise safety features, warranty coverage, and proper installation. Start by measuring your space and reviewing the checklist above, then test a few models in person to feel the difference in heat distribution before you buy.
