Quick questions
Are propane patio heaters safe to use on a wooden deck?
Yes, if you follow the manufacturer's instructions. Place the heater on a stable, level surface, keep it away from flammable materials, and never leave it unattended. Use a heater with a tip-over safety shutoff. Always check local fire codes.
How much does it cost to run an electric patio heater vs a propane one?
Electric heaters are generally cheaper per hour, especially if you have average electricity rates. Propane costs vary but are usually higher. However, electric heaters have lower heat output, so you may need more of them or run them longer to warm the same space. Check the current price on Amazon for both types.
Can electric patio heaters be used outdoors in rain?
Only if they are rated for outdoor use and have an IPX4 or higher water resistance rating. Always keep the plug connection dry and use a GFCI outlet. Never use a heater that is not explicitly designed for outdoor exposure.
