Heater for Outdoor Patio: How to Find the Right Option
Every Canadian patio has a point when colder evenings shorten the time people spend outside. Choosing a heater for outdoor patio use can extend the season when the unit is suited to the space and operated according to its instructions. Propane, electric and natural gas outdoor patio heaters differ in output, installation, portability and operating cost. The right choice depends on whether the space is open, covered or supplied by a suitable outdoor electrical circuit.
What Types of Outdoor Patio Heaters Are Available?
Patio heaters can use propane, electricity or a permanent natural gas connection. An outdoor electric patio heater may suit a covered or compact space, while fuel-burning models have different ventilation and clearance requirements. A portable power station can supply a compatible electric model temporarily, but heater wattage can reduce battery runtime quickly.
Propane Heaters for Open Outdoor Spaces
A freestanding propane patio heater carries its fuel cylinder in the base, so it does not need a fixed electrical outlet or buried gas line. Many models are designed for open patios and publish their heat output and coverage area on the rating label. Because combustion produces carbon monoxide and other exhaust gases, use the heater only in locations and configurations permitted by the manufacturer, with the required ventilation and clearances.
Electric Heaters for Patios and Covered Decks
Many electric patio heaters use infrared elements that direct radiant heat toward people and nearby surfaces instead of trying to warm all the surrounding air. They are sold as wall-mounted panels, ceiling bars and freestanding units. Suitability for a covered porch, pergola or balcony depends on the model’s outdoor rating, mounting instructions, clearances and electrical requirements. Operating cost depends on wattage, runtime and the applicable electricity rate.
Natural Gas Heaters for Permanent Outdoor Setups
A natural gas patio heater uses a permanent fuel connection and may suit an outdoor area used regularly. Installation cost and operating cost depend on the site, local gas prices and the heater’s output. Gas piping and appliance installation must follow the manufacturer’s instructions and applicable provincial and local requirements, normally with a qualified gas contractor.
Heater Type | Best For | Typical Heat Output | Mobility | Fuel or Power Supply |
Propane | Open-air patios, large yards | 30,000 – 48,000 BTU | High (wheeled bases) | Tank exchange / refill |
Electric Infrared | Covered decks, balconies, pergolas | 1,500W – 3,000W | Medium to Low (fixed/portable) | Grid or battery power |
Natural Gas | Permanent outdoor living areas | 30,000 – 50,000+ BTU | Fixed in place | Continuous line |
How to Choose the Right Outdoor Patio Heater
What narrows the field is how much space you’re heating, how much wind it gets, what power or gas reaches it and whether you want to wheel it away when the season turns.
Match Heat Output to Your Patio Size
Patio size and exposure determine whether one heater can cover the occupied seating area. Compare the model’s stated coverage with the area you intend to heat rather than choosing only by wattage or BTU rating. Wind, outdoor temperature, mounting height and nearby barriers affect perceived warmth, while every screen or enclosure must still preserve the ventilation and clearance required for the heater.
Consider Wind, Temperature and Patio Exposure
Wind can reduce the comfort provided by an outdoor heater, particularly when warm air disperses from an exposed space. A directional infrared model may focus heat more effectively on a sheltered seating area, but performance still depends on the model and installation. For freestanding units, follow the manufacturer’s wind limits and look for the specified stability or anchoring features.
Choose Between Portable and Fixed Heaters
The question is whether the heat needs to follow you around. A portable propane tower rolls up beside the dining table in early fall and over toward the hot tub or fire pit on weekend nights. Fixed heaters take the opposite approach. A flush-mounted electric panel leaves the floor of a narrow balcony clear and puts nothing at ankle height for kids and dogs to trip over.
Check Power Supply and Installation Requirements
A patio heater must match its power source and installation conditions. Battery-powered use is practical only when the heater’s continuous wattage is within the power source’s rated output and the expected runtime is acceptable. The EcoFlow DELTA 3 Classic Portable Power Station can support compatible temporary outdoor loads when its output and operating conditions match the equipment. For a patio heater, estimate runtime from the heater’s measured wattage and the available battery capacity, then allow for conversion losses.
The EcoFlow DELTA 3 Max Plus Portable Power Station (2048Wh) offers greater capacity for compatible outdoor electrical loads. Actual heater runtime depends on continuous wattage, battery state, temperature and conversion losses, so check both products’ instructions before connecting them.
How to Reduce Outdoor Patio Heating Costs
Operating cost depends on the energy price, heater wattage or fuel consumption and runtime. If a power station is used, include charging losses and the limited stored energy when comparing options.
Heat Occupied Areas Instead of the Entire Patio
Heating the whole patio means paying to warm cold air nobody is standing in. Point a radiant panel at each seating area, whether that’s the couch or the dining chairs. Switch each panel on as guests settle in, and turn it down when that spot empties.
Use Wind Barriers to Reduce Heat Loss
Cold air sweeping the deck carries away heat you paid for. Roll-down vinyl weather screens, heavy outdoor curtains, a cedar trellis or glass railing panels all cut the wind chill. The payback shows up on the dial: block the draft and the heater can run on medium and still deliver noticeably more warmth than before.
Set Heating Times Around Outdoor Activities
Use the heater only while the area is occupied and follow its instructions for supervision and controls. Do not connect a timer, smart plug, extension cord or power bar unless the heater manufacturer expressly permits that accessory and its rating matches the load. Adjustable heat settings can reduce energy use when full output is unnecessary.
What Should Canadian Homeowners Know Before Installing a Patio Heater?
Before installing a patio heater, check its power or gas requirements, how much clearance it needs and what your province and municipality require.
Check Electrical Circuits and Outdoor-Rated Equipment
Check the heater’s voltage, current, wattage, plug type and installation instructions before use. High-wattage heaters can use much of a branch circuit’s available capacity, and some models require a dedicated circuit or a properly installed 240V supply. Avoid adding other high-demand appliances to the same circuit, and ask a licensed electrician to confirm capacity when the requirements are unclear.
The receptacle matters as much as the load. When using portable power outside, protect equipment and connections from weather exposure and follow the product’s environmental limits. Outdoor outlets need the weather protection and ground-fault protection required for the location. Do not use an extension cord or power bar unless the heater manufacturer expressly permits it. Ask a licensed electrician when circuit capacity or suitability is uncertain.
Maintain Safe Clearance Around Combustible Materials
Clearance varies with the model, the output and how the unit is installed, so the distances that count are the ones printed for yours. Clearances from ceilings, walls, railings, furniture and other combustibles get measured, not eyeballed. Don’t put a propane heater under a wooden pergola or covered deck unless the instructions explicitly allow it.
Follow Ventilation Rules for Fuel-Burning Heaters
Fuel-burning heaters produce carbon monoxide and require the ventilation and placement specified by the manufacturer. Do not use an outdoor-only propane or natural gas heater in an enclosed or substantially enclosed space. A screened porch, awning or three-season room is suitable only if the heater is specifically approved for that configuration and all ventilation and clearance requirements are met.
Check Local Codes and Applicable Canadian Certifications
Choose a heater carrying a certification mark accepted by the relevant Canadian authority, and confirm that the mark applies to the complete product. Electrical and gas installations must meet the applicable provincial and local requirements, along with the manufacturer’s instructions.
Permit and inspection requirements differ by province and by municipality. Check with your local authority or a qualified licensed contractor before installing a permanent gas heater or running a new circuit out to the patio.
Conclusion
Propane gives you portability and the higher output an open space needs. On a small covered deck or a sheltered corner, electric infrared is often the practical answer, and natural gas may suit a permanent patio a gas line can reach. Whichever you choose, you’ll still want to check what it costs to run for a night, the clearance it needs, the area it covers and whether it’s approved for that spot. Sort those out before the cold sets in, and the patio stays good for dinner once the weather turns.
FAQ
What Is the Best Outdoor Patio Heater in Canada?
The best patio heaters depend on the space, exposure, available power or fuel, clearances and installation limits. An outdoor-rated electric infrared heater may suit a covered deck when its mounting and clearance requirements can be met. An open backyard may call for a different output or fuel type, based on the model’s stated coverage and wind limits.
Are Propane or Electric Patio Heaters Better?
They’re better at different things. Electric often costs less to run per hour at the lower wattages. Propane generally puts out more heat overall, and you can move it wherever the evening is. Your own hydro and propane prices, the heater’s output and how long you tend to leave it on all decide which actually costs less.
What Is the Cheapest Way to Heat My Patio?
A lower-wattage electric infrared heater may be economical for a small occupied area, but actual cost depends on the current electricity rate and runtime. Calculate electricity use by multiplying kilowatts by operating hours, then apply the local rate and applicable charges. Propane and natural gas costs likewise depend on local prices and fuel consumption. Focus heat on occupied seating and turn the heater off when the area is empty.
Do Outdoor Heaters Work in the Winter?
Outdoor heaters can operate in winter when the model is rated for the temperature, weather exposure and installation. Directional infrared units heat people and surfaces directly, while wind can reduce comfort from any heater in an exposed area. Compare the stated operating range, coverage, clearances and wind limits before choosing a location.
Can an Outdoor Space Heater Work Under a Covered Patio?
Yes, an electric infrared heater can, as long as you maintain the clearances from ceilings and beams specified in the manual. Don’t run a propane or natural gas heater under a covered patio unless the area is open on multiple sides and the unit is specifically certified for covered residential installation. If you can’t find that certification in the instructions, assume the answer is no.
