Best Extension Cord For Space Heater Buying Guide

Before choosing the best extension cord for space heater you should consider following options:

1. Length: Space heaters have short cords that limit their placement. Make sure the cord is long enough to reach from an outlet to the space where it will be used.

If you plan to use the heater in a large room, buy a model with an extension cord already attached.

2. Wattage: The higher the wattage, the faster the heater will warm up a room. But higher wattage also causes the heater to cost more to operate and may pose a fire hazard.

Generally speaking, you should not buy a space heater with a wattage above 1500 watts unless you plan to use it in a large, open area.

3. Energy Efficiency: Look for a heater that has an energy efficiency rating of at least B or higher. This rating is expressed as a ratio of heat output to energy input, with a higher number indicating a more efficient heater.

4. Temperature control: Look for a heater with a built-in thermostat that turns the unit off when the room temperature reaches your desired setting.

Also, look for a heater with a tip-over switch that cuts off the power source when the heater is knocked over.

5. Safety features: Look for a unit with a screen over the heating element to protect against accidental contact. Also, make sure the heater has a stable base so it doesn’t tip over.

6. Cost: The cost of energy to operate a space heater is generally very low, but the cost may be a factor in your buying decision.

The higher the wattage, the more expensive the unit will be to operate.
