This time of year, the evenings are starting to cool off, but we STILL want to sit out on the deck. Many of us will turn to using a Patio Heater to take that chill out of the air...but are Patio Heaters SAFE???
When used correctly, patio heaters offer a safe way to heat your favorite outdoor spaces. But like any home heating source, they can be dangerous if not used correctly. Always follow the manufacturer’s instructions, and never leave a patio heater unattended.
Here are some tips to ensure your patio heater is being used safely:
• Give it space. Over time, your patio heater will generate a lot of heat. (That’s why you bought it, right?) To prevent fire hazards, keep your heater a safe distance away from walls, ceilings, furniture, carpet or any other flammable material. Experts recommend providing three feet of clearance around all sides of the heater, unless otherwise specified by the heater’s manufacturer.
• Find a level spot. Only use your patio heater on a flat, level surface. Placing your heater on an incline could cause it to roll or tip over, creating both a fire and burn hazard.
• Check for leaks. When setting up a natural gas or propane patio heater, always conduct a thorough inspection to ensure there are no gas leaks. You can do this by applying a soapy water solution to your gas tank and hose connections. If you see bubbles rising from any connection points or smell gas, turn off the heater and tighten the connections. If you can’t stop the leak, get your heater serviced before using it.
• Light it safely. When lighting up a gas patio heater, always follow the manufacturer’s instructions. While most heaters have an electric ignitor button, others may require you to light the pilot manually. If so, use a candle or grill lighter that allows you to start the flame from a safe distance. If you can’t get the burner to light right away, turn off the heater and wait at least five minutes. Then try again. This will prevent gas buildup, which could lead to an explosion or flash burn.
• Keep a fire extinguisher nearby. Even if you follow every safety precaution, accidents can still happen. That’s why it’s wise to always keep a fire extinguisher nearby. Just make sure the fire extinguisher you buy is the right class for your patio heater’s fuel source (Class B for gas; Class C for electric; or a multipurpose extinguisher for both).
• Watch it carefully. Never leave a patio heater running while unattended. Be sure to keep kids and pets a safe distance away at all times to prevent burns. And avoid using your heater when winds exceed 10 miles per hour – the heater could blow over, or the flame could blow out.
• Cover it up. Patio heaters are designed to be weather-resistant. But over time, your heater may develop problems if it’s left out in the elements. Correctly storing your heater when it’s not in use will prevent it from getting clogged with bugs and debris, and also prevent rust. You can purchase a custom cover to protect your heater when it’s not being used. And if you won’t be using it for several months, it’s a good idea to disassemble it and store the heater indoors. Just be sure to leave the propane tank outside. Propane should never be stored indoors — even in a shed or garage.
