Buying Guide: Gas Heaters
📋 Table of Contents
1What size gas heater do I need for my room?
Check your room's square footage and ceiling height, then match it to the heater's BTU output—roughly 10 BTU per square foot is a good starting point. A heater that's too small won't warm the space effectively, while one that's oversized wastes fuel and money.
2What's the difference between flued and unflued gas heaters?
Flued heaters vent exhaust outside through a chimney or wall duct, making them safer for enclosed spaces. Unflued heaters release heat and fumes directly into the room, so they're only suitable for well-ventilated areas and require periodic air changes.
3Should I buy a wall-mounted or portable gas heater?
Wall-mounted heaters save floor space and are permanent fixtures best for regular use, while portable units offer flexibility if you move between rooms. Portables are easier to install but less efficient since they're not ducted, and they take up valuable floor space.
4What safety features matter most in a gas heater?
Look for oxygen depletion sensors (ODS), automatic shutoff switches, and sturdy guards to prevent burns. These features prevent dangerous carbon monoxide buildup and reduce fire hazards, especially important if you have kids or pets.
5Is it worth paying more for a high-efficiency gas heater?
High-efficiency models convert more fuel to usable heat, meaning lower running costs that add up over time if you use the heater regularly. If you only need occasional heating, a basic model is fine, but for daily winter use, efficiency pays for itself within one or two seasons.
