Electric Patio Heater vs Gas - Which Suits You?

A patio that looks exceptional at 4pm can feel deserted by 7pm when the temperature drops. The electric patio heater vs gas decision determines how comfortably guests can use your terrace, outdoor kitchen or dining area through the British shoulder seasons. Both options have a place, but they heat differently, suit different layouts and create very different buying considerations.

For a compact covered seating area, an electric infrared heater can provide focused, instant warmth with minimal visual impact. For a larger, open entertaining space, a powerful gas heater may be the practical answer. The best choice is not simply the heater with the highest output - it is the one matched to your available power, shelter, seating plan and how often you want to entertain outdoors.

Electric Patio Heater vs Gas: The Core Difference

Electric patio heaters use infrared elements to warm people and nearby surfaces directly. They do not need to heat all the surrounding air first, which makes them particularly effective in sheltered spaces, beneath pergolas and around dining tables. Switch one on and the heat is almost immediate.

Gas patio heaters burn propane or butane from a cylinder. Their heat is more ambient, creating a wider area of warmth around the appliance. This makes them a familiar choice for open patios, pub gardens and larger hospitality terraces where guests move around rather than sit in one fixed position.

That difference matters on a breezy evening. Infrared electric heat can still reach the people sitting in its line of coverage, whereas warm air generated by a gas heater is more easily carried away. On the other hand, one freestanding gas mushroom heater can serve a broad central zone without relying on wall space, ceiling height or a nearby electrical supply.

Heat Output and Coverage

A gas heater will usually deliver more headline heat output. Many domestic freestanding models sit around 12kW to 13kW, while commercial units can be higher. This makes gas a strong contender for expansive patios, beer gardens and open-sided spaces where a single source needs to make a noticeable difference.

Electric heaters are commonly rated from around 1.5kW to 3kW, although larger commercial installations can use multiple units. Comparing kilowatts alone can be misleading. A 2kW infrared heater mounted correctly above a six-seat dining table can feel far more effective than a powerful gas heater positioned too far away in an exposed garden.

Coverage is determined by mounting height, heater angle, wind exposure and the type of use. For seated dining, focused radiant heat is usually preferable. For standing drinks receptions or a large outdoor bar area, broader gas warmth can be more suitable. Commercial buyers should also consider zoned heating: several electric units over occupied tables often use energy more intelligently than trying to heat every square metre of an outdoor terrace.

Installation, Positioning and Flexibility

Electric heaters need a suitable electricity supply and should be installed in line with the manufacturer’s guidance. Wall-mounted and ceiling-mounted models deliver a clean, integrated finish, particularly with awnings, covered terraces and modular outdoor kitchens. They also keep floor space clear - valuable where furniture, grills and serving stations already compete for room.

Portable electric models offer more flexibility, but the cable still needs careful management. Avoid trailing leads across walkways, and use outdoor-rated electrical equipment where required. A dedicated outdoor circuit installed by a qualified electrician is often the right route for permanent, premium installations.

Gas heaters are usually easier to place anywhere on a level patio because they are self-contained. This is useful in gardens without convenient power access and for hospitality operators who rearrange tables frequently. However, they need safe clearances, upright storage and space for the cylinder within the base or alongside the heater.

Do not treat a gas patio heater as an indoor or enclosed-space appliance. Carbon monoxide and ventilation requirements are serious considerations. Electric infrared heaters are generally the more straightforward option for well-ventilated covered areas, but every model has its own clearance and installation rules. Check these before ordering rather than trying to make a heater fit a space it was not designed for.

Running Costs: What Should You Expect?

Electricity and bottled gas prices vary, so there is no universal winner on running cost. Calculate the likely spend from the heater’s rated consumption, your current electricity tariff or cylinder price, and the number of hours you expect to use it.

Electric heaters make cost control simple. A 2kW unit running for one hour uses 2kWh of electricity. Timers, remote controls and multi-level heat settings can reduce waste, particularly when guests only use the patio for a short period after dinner. Direct infrared heat also means you are heating the occupied zone rather than an entire garden.

Gas heaters can offer strong heat for the money when a large, open area needs coverage. The trade-off is cylinder management. A 13kg propane cylinder will not last indefinitely at high output, and running out halfway through a party or service period is an avoidable frustration. Keep a full spare cylinder ready if gas is central to your entertaining setup or commercial operation.

For occasional home use, electric often feels easier because there is no fuel to order, lift or store. For long evenings in an exposed, larger space, gas may justify its fuel requirement through its higher overall output.

Appearance, Atmosphere and Noise

A gas flame heater adds visual presence. Traditional mushroom designs create a familiar terrace atmosphere, while pyramid models place the flame at the centre of the experience. They suit customers who want their heating to be a visible feature alongside fire pits, outdoor bars and statement garden furniture.

Electric heating is more discreet. Slim black, stainless steel or contemporary wall-mounted units can blend into a pergola, canopy or exterior wall without interrupting the view across the garden. There is no flame, no cylinder in sight and no need for guests to sit around a central appliance.

Neither system should create significant operating noise, though gas units may produce a faint burner sound. If design continuity is the priority, choose electric heaters during the planning stage of an outdoor kitchen or covered dining area. Retrofitting is possible, but positioning and power provision are much easier before surfaces, cabinetry and lighting are finalised.

Safety and Maintenance Considerations

Both heater types require sensible use. Electric models should have the correct IP rating for their intended location, be securely mounted where applicable and be kept clear of combustible materials. Inspect cables, plugs and fixings regularly, especially after winter weather.

Gas heaters need additional attention. Check hoses and regulators, inspect the burner and ignition system, and keep the cylinder stored and connected according to the manufacturer’s instructions. Never attempt makeshift repairs to gas components. In busy venues, staff should know how to switch the heater off safely and where cylinders are kept.

For homes with children, pets or tight seating arrangements, a mounted electric heater can reduce the risk of someone brushing against a hot freestanding unit. Gas heaters have protective guards, but their surfaces and surrounding areas can still become very hot in operation.

Which Patio Heater Is Right for Your Space?

Choose an electric patio heater when you have a sheltered or semi-covered patio, a reliable power supply and a defined seating or dining zone. It is the strongest choice for pergolas, outdoor kitchens, balconies, garden rooms with open sides and refined entertaining spaces where a clean installation matters.

Choose gas when you need broad warmth across an open, flexible area and do not have practical access to outdoor electricity. It remains a compelling option for large gardens, temporary event spaces, hospitality terraces and busy entertaining areas where people are standing, circulating and gathering around the heater.

If your patio includes both a covered dining table and an open lounge area, a mixed approach can be sensible. Use electric infrared heaters for the fixed dining zone, then add a gas heater or fire feature for the more exposed social area. This avoids over-specifying one appliance to solve two very different heating jobs.

Before the first cold evening arrives, measure the area, identify prevailing wind exposure and decide where people actually sit. Buy for that real-world layout, not just the product photograph. The right heater turns a premium outdoor space from something admired through the window into somewhere guests genuinely want to stay.
