Patio Heater FAQ
Updated 25 Jun 2025
+− Are electric patio heaters safe for covered patios?
Yes—choose a model rated for indoor or semi-enclosed use and respect the manufacturer’s overhead and front clearances.
+− How much does it cost to run a propane heater per hour?
A 40 000 BTU propane heater burns about 1 lb of fuel per hour—roughly $1.50 at a $15 cylinder refill.
+− What coverage area will a 1 500-watt electric heater warm?
About 50 sq ft in calm conditions (5 × 10 ft). Windy patios reduce effective range.
+− Do patio heaters need to be covered when not in use?
Yes—use a UV-resistant, breathable cover to prevent corrosion and extend element life.
+− Can I leave a patio heater outside in the rain?
Look for IPX4 (splash-proof) or higher weather ratings; otherwise move or cover the unit during heavy rain.
