Differences Between a Gas and an Electric Patio Heater

Heat Output and Coverage

Gas patio heaters are excellent for heating large spaces, covering up to 20 square meters, and provide powerful radiant heat. They warm areas quickly, making them ideal for open spaces and larger gatherings. However, wind can reduce their efficiency, although some models include ceramic fascias to help counteract this issue.

Electric outdoor heaters work best in smaller, enclosed spaces, covering up to 15 square meters. Using infrared technology, they heat objects and people directly rather than the surrounding air. Their performance is consistent even in windy conditions, as there is no open flame to extinguish.

Efficiency and Running Costs

An average gas patio heater typically incurs higher running costs, averaging around £3 per hour in the UK due to the expense of gas refills. While natural gas models may offer better long-term savings, they often require professional installation.

Electric heaters are more cost-effective, with running costs averaging £0.67 per hour in the UK. They are highly energy-efficient, delivering targeted heat directly to the user. However, their operational cost depends on electricity prices, which can vary regionally (1).

Portability and Placement

Gas outdoor heaters offer full portability as they do not rely on power sockets. They are suitable for large, open spaces but require storage space for gas canisters or a connection to a gas line. This flexibility makes them ideal for areas without easy electrical access.

Electric heaters are lightweight and compact, making them easy to move and install. However, they depend on nearby power outlets, limiting placement options. Their plug-and-play design is convenient for small patios or semi-enclosed spaces with access to electricity.

Pros and Cons of Each

Pros of Gas Heaters

An outdoor gas heater provides powerful heat, making it perfect for larger gatherings and expansive outdoor areas. They quickly warm spaces and are not reliant on electrical sockets, offering greater placement flexibility.

This makes them well-suited for open-air settings and social events, especially in larger gardens or patios without easy access to power.

Cons of Gas Heaters

Outdoor gas heaters come with higher running costs due to regular refills for portable propane models. They are often bulky and require routine maintenance, including gas line checks, to ensure safety and efficiency. Additionally, they produce CO2 emissions, which negatively impact the environment.

Pros of Electric Heaters

Electric patio heaters deliver instant and adjustable heating, providing targeted warmth for smaller spaces. They are cost-efficient to operate, with no need for fuel refills.

Environmentally, they are a cleaner option with zero direct carbon monoxide emissions, especially when paired with renewable energy sources.

Cons of Electric Heaters

An electric heater must be positioned near power outlets, which can limit their placement options. They are less effective for heating larger areas compared to gas heaters.

Additionally, the warmth they provide dissipates quickly once turned off, making them less ideal for prolonged use in open spaces.

Choosing a Gas or Electric Patio Heater For Your Space

Environmental Impact

A gas patio heater emits CO2 and other pollutants during operation, contributing to a larger carbon footprint. While some models are designed for cleaner burning, they still produce emissions.

Electric heaters, on the other hand, offer a more environmentally friendly solution with zero direct emissions. They can also be powered by renewable energy sources, further reducing their impact on the environment.

Space and Location

Gas heaters are better suited for large gardens, where their quick and powerful heat can cover more space effectively. For small patios or semi-enclosed areas, electric heaters are a safer and more practical option, as they require no ventilation and are easy to position.

Maintenance and Longevity

Gas heaters often require professional installation and regular maintenance to ensure safety and efficient performance. This includes checking gas lines and burners.

Electric heaters are simpler to install and maintain, with no need for special ventilation or fuel storage. Regular cleaning is typically all that’s required to keep them functioning.

Design and Aesthetics

Gas heaters tend to be bulkier, though modern designs are available to suit different outdoor styles.

Outdoor electric heaters offer more compact and stylish options, such as wall-mounted or tabletop designs, making them ideal for smaller spaces or decorative purposes. They blend easily into various outdoor setups while offering efficient heating.

Frequently Asked Questions

What is the Price Difference Between a Gas and Electric Outdoor Heater?

Electric heaters are more affordable upfront, with prices ranging from £50 to £200 for smaller to medium-sized models available for around £50.

Gas heaters, while often more powerful, typically start at £200 for a quality model. Cheaper options under £100 are available, but they may lack durability.

How Important Is Ventilation for These Types of Heaters?

Ventilation is critical, especially for gas heaters, to prevent the buildup of harmful gases like carbon monoxide. Without adequate airflow, there’s a risk of the heater blowing out or producing unsafe emissions.

Electric heaters, in contrast, don’t rely on ventilation, making them a safer choice for enclosed or semi-enclosed spaces.

Which Heater Is Better for Year-Round Use?

Electric heaters are better suited for year-round use due to their ease of operation, consistent performance, and suitability for both indoor and outdoor settings.

Gas heaters, while powerful, are less practical in extreme weather and require more effort to maintain. For frequent, year-round use, electric options are more versatile.

How Weather-Resistant Are Gas and Electric Patio Heaters?

Gas patio heaters are generally more weather-resistant and designed to handle outdoor conditions, though they require protection from rain to avoid damage.

Electric patio heaters, while effective, are more sensitive to moisture and need to be shielded from rain or snow. Proper placement and weatherproofing are essential for both types to ensure durability.

Conclusion

In conclusion, the choice between gas and electric patio heaters depends on your specific needs, space, and budget.

Electric heaters are ideal for smaller, enclosed areas, offering energy efficiency and convenience, while many gas patio heaters excel in heating larger, open spaces with their powerful output.

Consider factors like running costs, environmental impact, and placement options to make the best decision for your outdoor setup. Both options provide reliable warmth, ensuring you can enjoy your patio comfortably year-round.
