Buying Guide

Buying Guide: Best Gas Space Heater

Heating Capacity & Coverage Area

  • Measure the square footage of the area you need to heat
  • Check the heater’s BTU (British Thermal Unit) output, which indicates its heating power
  • Consider ceiling height, as taller rooms require more BTUs
  • Account for insulation quality and climate; poorly insulated spaces in colder climates need a more powerful heater

Safety Features

  • Ensure the heater has an Oxygen Depletion Sensor (ODS) that automatically shuts it off if oxygen levels drop
  • Look for a tip-over switch that turns the unit off if it’s accidentally knocked over
  • Check for a cool-to-touch exterior to prevent burns, especially important for homes with children or pets
  • Verify it has safety certifications from recognized testing laboratories like UL or CSA

Ventilation & Installation Requirements

  • Determine if you need a vented or vent-free model based on your space and local building codes
  • Vent-free heaters are more flexible for placement but require adequate room size and air circulation
  • Vented models require installation to an exhaust system but are safer for prolonged use in airtight homes
  • Consider professional installation costs and requirements for more complex units

Fuel Type & Efficiency

  • Decide between natural gas or propane models based on availability and your home’s existing connections
  • Check the heater’s efficiency rating to understand fuel consumption and operating costs
  • Consider models with adjustable thermostats and multiple heat settings for better energy control
  • Look for features like electronic ignition instead of a standing pilot light to improve efficiency

Portability & Design

  • Consider whether you need a fixed unit or a portable model with caster wheels for easy movement
  • Check the dimensions and weight to ensure it fits your intended space
  • Look at the design and finish to ensure it complements your room’s decor
  • Consider the noise level, especially if you plan to use it in a bedroom or quiet space

Convenience Features

  • Look for models with remote controls for easy adjustment from across the room
  • Consider programmable thermostats and timers for automated operation
  • Check for multiple fan speeds for better control over heat distribution
  • Some models include built-in humidifiers to prevent dry air during heating

FAQs

What should I look for in a gas space heater?

Look for safety features like oxygen depletion sensors and tip-over switches to prevent accidents. Consider the heating capacity (measured in BTUs) to ensure it can warm your space efficiently. Portability and ease of installation are also important factors.

How do vented and ventless gas heaters compare?

Vented heaters expel fumes outside, making them safer but more complex to install. Ventless models are easier to set up but require proper ventilation to avoid indoor air quality issues. Choose based on your space and safety preferences.

Are gas space heaters energy-efficient?

Gas heaters are generally more energy-efficient than electric models, especially for larger spaces. They provide faster heating and lower operating costs in areas with cheap natural gas. However, efficiency can vary by model and usage.

What safety features are essential?

An oxygen depletion sensor (ODS) is critical to shut off the heater if oxygen levels drop too low. Tip-over protection and overheat shut-off are also must-haves for safe operation. Always check for certifications like UL or CSA.

How do I determine the right size heater for my room?

Calculate the room’s square footage and match it to the heater’s BTU rating (typically 20-30 BTUs per square foot). Consider ceiling height and insulation levels, as poorly insulated rooms may require more power. Oversized heaters can waste energy, while undersized ones won’t heat effectively.

Are gas space heaters cost-effective?

Gas heaters often have lower operating costs compared to electric models, especially in cold climates. However, upfront costs can be higher due to installation and venting requirements. Factor in long-term savings versus initial investment.

Can I use a gas heater in a bedroom?

Ventless gas heaters are generally not recommended for bedrooms due to potential CO buildup. Vented models with proper installation may be safer but check local codes. Always prioritize ventilation and safety when using heaters in enclosed spaces.

What maintenance do gas heaters require?

Regularly clean the burner and check for gas leaks to ensure safe operation. Inspect the venting system (if applicable) for blockages or damage. Annual professional servicing is recommended for optimal performance and longevity.
