How to Use Lasko Space Heater: A Comprehensive Guide

Lasko space heaters are a popular choice for supplemental heating in homes and offices. These versatile devices offer a range of features and functions to help you stay warm and comfortable while also saving energy. In this comprehensive guide, we’ll dive deep into the step-by-step process of using a Lasko space heater, covering everything from electrical safety to advanced energy-saving features.

Electrical Safety and Outlet Compatibility

Before using your Lasko space heater, it’s crucial to ensure that the electrical outlet can handle the device’s power requirements. Lasko space heaters typically draw between 1,500 to 1,800 watts of power, depending on the model. To avoid overloading the circuit and potential fire hazards, have a certified electrician test the intended outlet to confirm its compatibility.

Outlet Compatibility Checklist

  • Outlet capacity: The outlet should be rated for at least 15 amps to safely accommodate the heater’s power draw.
  • Circuit breaker: Ensure the circuit breaker for the outlet is properly sized and functioning correctly.
  • Grounding: The outlet should be properly grounded to prevent electrical shocks.
  • Outlet condition: Check for any signs of damage, such as loose connections or exposed wiring, which could pose a safety risk.

Placement and Positioning

Proper placement and positioning of your Lasko space heater are crucial for both safety and efficiency. Follow these guidelines to ensure your heater is set up in a safe and optimal location:

  1. Level Surface: Place the heater on a flat, level, and stable surface to prevent it from tipping over.
  2. Clearance: Maintain a minimum clearance of 3 feet (0.9 meters) from any walls, furniture, or other objects. This helps prevent the heater from overheating or causing a fire.
  3. Avoid Flammable Materials: Keep the heater away from curtains, bedding, clothing, and other flammable materials.
  4. Ventilation: Ensure the heater is placed in a well-ventilated area to allow for proper air circulation and prevent overheating.
  5. Accessibility: Position the heater in a location that is easily accessible for adjustments and monitoring.

Heat Settings and Thermostat Control

Lasko space heaters typically offer multiple heat settings, allowing you to customize the warmth to your desired level. The available settings may include fan-only, low heat, and high heat. Choose the appropriate setting based on your room temperature and personal comfort preferences.

Thermostat Control

Many Lasko space heaters feature advanced thermostat controls, enabling you to maintain a consistent and comfortable room temperature. Here’s how to use the thermostat functions:

  1. Save-Smart® Function: If your Lasko heater has a small, green leaf pictured on one of its control buttons, it features the Save-Smart function. This allows you to set the automatic thermostat to maintain your room’s warmth while using less energy. To use this function, press the green leaf to activate it, then set your heater’s thermostat to the desired temperature using the plus and minus buttons. The heater will automatically adjust its heat output to maintain the set temperature while using less energy.

  2. Auto-Eco Thermostat Function: This feature helps maintain comfort in your room while using less energy. Press the plus and minus (or up and down arrow) buttons on your heater or its remote while it’s running to activate the Auto-Eco function. Once activated, you can set the thermostat to your desired temperature. The heater will now maintain your room’s perfect warmth level while using less energy.

Thermostat Settings and Energy Efficiency

  • Recommended Temperature: The default Save-Smart temperature is typically set to 72°F (22°C), which is considered an energy-efficient and comfortable setting.
  • Temperature Range: Lasko space heaters generally allow you to adjust the thermostat within a range of 60°F (15°C) to 90°F (32°C), depending on the model.
  • Energy Savings: The Save-Smart and Auto-Eco functions can help reduce energy consumption by automatically adjusting the heater’s output to maintain the desired temperature.

Monitoring and Safety Precautions

Proper monitoring and safety precautions are essential when using a Lasko space heater. Follow these guidelines to ensure safe and responsible operation:

  1. Unattended Operation: Never leave the heater unattended or running while you sleep. Always turn off the heater when you leave the room or go to bed.
  2. Overheating Prevention: Lasko space heaters are equipped with various safety features, such as automatic shut-off mechanisms, to prevent overheating. However, it’s still important to monitor the heater’s operation and immediately turn it off if any issues arise.
  3. Cleaning and Maintenance: Dust and debris can accumulate in the heater, reducing its efficiency and increasing the risk of fire. Unplug the heater, wait for it to cool down, and then use a soft brush or vacuum attachment to clean the unit regularly.
  4. Troubleshooting Power Issues: If your heater isn’t turning on, check the power cord for damage and ensure it’s plugged in securely. If the problem persists, try resetting the circuit breaker or using a different outlet.
