Infratech W-Series

What to check before buying a patio heater for a large garden
Choosing the right patio heater for a large garden requires careful consideration of several key factors. The size of your garden and the specific area you want to heat will determine the necessary heat output. For a large garden, you typically need a heater with at least 40,000 BTU for gas models or 4,000W for electric models to effectively warm a 150-200 square foot area.
Fuel type is another critical decision. Electric heaters are cleaner, quieter, and require less maintenance, but they may have higher running costs and need a nearby power outlet. Gas heaters, usually propane, offer higher BTU outputs and are more portable, but they produce fumes and require fuel tank management. Consider your garden's layout and access to power or gas when making your choice.
Build quality and weather resistance are essential for outdoor use. Look for heaters with stainless steel or powder-coated aluminum construction that can withstand rain, wind, and UV exposure. Safety features like automatic shut-off switches, tip-over protection, and cool-touch surfaces are also important, especially if you have children or pets.
Mistakes to avoid when buying a patio heater for a large garden
One common mistake is underestimating the heat output needed for a large garden. A small 10,000 BTU heater will not effectively warm a 200 square foot patio, leading to disappointment and wasted money. Always measure the area you want to heat and choose a heater with a coverage rating that matches or exceeds that size.
Another mistake is ignoring wind conditions. In an open garden, wind can significantly reduce a heater's effectiveness. Infrared heaters are less affected by wind than convection heaters, making them a better choice for exposed areas. Additionally, avoid placing the heater too far from seating areas; the heat should be directed where people will sit.
Finally, do not overlook installation requirements. Some electric heaters require hardwiring by a professional, which adds to the total cost. Gas heaters need proper ventilation and safe propane tank storage. Always check the manufacturer's specifications and local regulations before purchasing.
