Factors to Consider When Choosing Backyard and Garden Heaters

Choosing the right heater can make all the difference in the comfort and usability of your outdoor space. Here are some key factors to consider when making your selection:

1. Heater Type and Heat Output: From fire pits to gas heaters, each type has its unique benefits and drawbacks. Consider your specific needs and preferences. Do you want the ambience of a wood-burning fire pit? The simplicity and cleanliness of an electric heater? Or the powerful heat of a gas heater? Additionally, think about how much heat you’ll need. The heat output of outdoor heaters is usually measured in BTUs (British Thermal Units) for gas and watts for electric heaters. Higher BTU’s or watts mean more heat.
2. Fuel Source and Accessibility: Consider what type of fuel you prefer to use. Wood can create a beautiful, natural ambience but requires a steady supply and leaves ash behind. Propane is a convenient, clean-burning fuel, but you’ll need to keep spare tanks. Natural gas heaters provide continuous operation, but they require a permanent gas line. Electric heaters are very convenient and clean but may not provide as much heat as their gas counterparts. Additionally, remember that electric heaters will need access to an electrical outlet, which could be a limiting factor in your yard or garden.
3. Space Size and Configuration: When selecting a heater for your outdoor area, you must take into account the size, layout, and safety considerations of the space. Heaters come in various sizes and heat outputs, making some models better suited for certain environments than others. If your outdoor space is large and encourages group gatherings, a centerpiece heater such as a fire pit could be an ideal choice. However, due to the open flames and potential for emitting sparks, fire pits should be situated at least 20 feet away from any structures, vegetation, or overhead obstructions (including tree branches). This safety buffer helps to prevent accidental fires. Similarly, gas and electric heaters also require specific clearances for safe operation. A standard rule is to maintain a minimum of 3 feet of clearance on all sides of the heater and 6 feet above it.When it comes to enclosed or structured spaces, mounted infrared heaters can be an excellent choice, given you have access to a power source. These heaters should be mounted at a safe distance from flammable materials and high-traffic areas to avoid accidental contact or disruption. The right placement ensures both efficient heating and safety for everyone.
4. Climate and Weather: Your local climate significantly influences the effectiveness of your outdoor heater. Most outdoor heaters can operate efficiently when the ambient temperature is above 40°F (4.4°C). Below this, the efficiency may drop, making the heater less effective. Also, it’s crucial to remember that while outdoor heaters can reduce cooler temperatures, they can’t combat extreme cold.Wind can greatly affect heat dispersion, making the heater less efficient, and potentially creating safety concerns. Therefore, if you frequently encounter windy conditions in your area, it would be beneficial to consider using your heater in a more sheltered outdoor setting like a walled patio or gazebo. Alternatively, choosing a heat source that isn’t as affected by wind, such as an infrared heater, could be a more effective solution.For areas that get more rainfall, heaters made of materials resistant to rust and corrosion like stainless steel or certain treated metals should be considered. Regardless of where you live, it’s always a good practice to cover your heater or store it in a dry place when it’s not in use to protect it from weather damage.
5. Safety Features: Safety should always be a priority when using backyard and garden heaters and refer to our below section where we cover safety features for out door heating in detail.
6. Budget: Finally, consider your budget. Outdoor heaters can range from affordable to high-end, with various features and capabilities. Consider not just the initial cost of the heater but also the long-term operating costs. Electric heaters typically have lower running costs, while propane and natural gas can be more expensive over time.

Taking the time to consider these factors can help ensure you select a heater that’s right for your space, meets your needs, and provides you with enjoyable outdoor experiences for many seasons to come.
