Complete Buyer's Guide: How to Choose a Gas Heater for Your Home
1. Understanding BTU and Room Size
BTU (British Thermal Unit) measures heating capacity, and getting this right is crucial for efficiency and comfort. For small rooms up to 300 square feet, 10,000 BTU is usually sufficient, while medium spaces (500-750 sq ft) need 15,000-20,000 BTU. Larger areas or open floor plans (1,000+ sq ft) typically require 25,000-30,000 BTU or more.
Remember that factors like ceiling height, insulation quality, and window efficiency can significantly affect your actual heating needs.
2. Ventless vs. Vented Heaters
Ventless heaters are easier to install since they don’t require external venting, but they do need adequate room ventilation to prevent moisture buildup and ensure proper combustion. Vented models, like direct vent heaters, are safer for tightly sealed modern homes because they bring in fresh air from outside and exhaust combustion gases directly out.
Ventless units are typically more energy-efficient (up to 99.9% efficient) since no heat escapes through vents.
3. Blue Flame vs. Infrared Technology
Blue flame heaters work by convection, warming the air first which then circulates throughout the room – similar to central heating systems. This provides even, consistent warmth that’s ideal for well-insulated spaces. Infrared heaters use radiant heat, warming objects and people directly rather than the air, making them more effective in drafty areas or spaces with high ceilings.
Infrared heat feels more immediate but can be less evenly distributed, while blue flame provides that familiar, whole-room warmth.
4. Safety Features You Shouldn't Compromise On
Always prioritize heaters with oxygen depletion sensors (ODS) that automatically shut off the unit if oxygen levels drop dangerously low. Look for cool-touch cabinets to prevent burns, especially in homes with children or pets. Tip-over protection is another critical feature that cuts power if the unit is knocked over.
Modern safety certifications like ANSI approval ensure the heater meets rigorous safety standards for indoor use.
5. Natural Gas vs. Propane: Fuel Considerations
Natural gas is convenient if you have an existing gas line, offering continuous operation without tank refills. Propane provides portability and is ideal for areas without natural gas service, though you’ll need to monitor tank levels. Some dual-fuel models offer the best of both worlds, giving you flexibility based on availability and cost.
Consider your local fuel costs and availability – natural gas is often cheaper per BTU, but propane offers more installation flexibility.
6. Installation: DIY vs. Professional
Many ventless wall-mounted heaters are designed for DIY installation with included hardware, while freestanding models typically require no installation at all. However, any heater requiring gas line connections or venting should be installed by a qualified professional to ensure safety and compliance with local codes.
Always check your local regulations, as some areas have restrictions on ventless heater use or require specific installation standards.
7. Energy Efficiency and Operating Costs
Look for high-efficiency models (99.9% efficient) to minimize fuel consumption and reduce operating costs. Ventless heaters are typically more efficient than vented models since no heat escapes through ventilation systems. Features like modulating burners or programmable thermostats can further improve efficiency by precisely matching heat output to your actual needs.
While initial cost is important, consider long-term operating expenses – a slightly more expensive but efficient heater may save you money over time.
Frequently Asked Questions
1. Are gas heaters safe to use indoors?
Yes, modern gas heaters are designed with multiple safety features that make them safe for indoor use when properly installed and maintained. Look for units with oxygen depletion sensors (ODS), automatic shut-off features, and cool-touch cabinets. Always ensure adequate ventilation according to manufacturer instructions, and never use outdoor-rated heaters indoors.
2. How much does it cost to run a gas heater?
Operating costs vary based on fuel type, local rates, and heater efficiency. Natural gas typically costs less per BTU than propane, and high-efficiency models can reduce fuel consumption by 20-30% compared to standard units. The most economical approach is choosing a properly sized heater for your space and using thermostat controls to maintain consistent rather than maximum temperatures.
3. Can I install a gas heater myself?
Many ventless models with included mounting hardware are designed for DIY installation, but any heater requiring gas line connections or venting should be installed by a qualified professional. Always check local building codes and manufacturer recommendations – improper installation can void warranties and create safety hazards. When in doubt, professional installation is worth the investment for peace of mind.
4. What's the difference between blue flame and infrared heaters?
Blue flame heaters use convection to warm the air, providing even, whole-room warmth similar to central heating systems – ideal for well-insulated spaces. Infrared heaters use radiant heat to warm objects and people directly, making them more effective in drafty areas but potentially less evenly distributed. Blue flame feels more like traditional heating, while infrared provides immediate warmth to whatever it’s pointed at.
5. How long do gas heaters typically last?
With proper maintenance, quality gas heaters can last 10-15 years or more. Regular cleaning of burners and components, annual inspections, and following manufacturer maintenance schedules significantly extend lifespan. Higher-end models with better construction materials often outlast budget options, making them better long-term investments despite higher initial costs.
