Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Heat Output And Room Coverage
- BTU Rating: Choose a unit with BTUs matched to your space. Higher BTUs cover larger areas but require proper clearances and gas supply.
- Room Size: Estimate square footage and insulation levels. A well-insulated room needs fewer BTUs than a drafty space.
- Supplemental Vs. Primary Heat: Use lower-BTU units for zone heating and higher-BTU ventless systems for primary supplemental heat.
Ventless Vs. Vented Systems
- Ventless (Vent-Free): Delivers most heat into the room and typically has higher efficiency ratings. Check local building codes; some regions restrict or regulate ventless use.
- Vented: Requires a chimney or flue and vents combustion products outdoors. May provide less immediate room heat but is accepted more universally by codes and may improve indoor air quality concerns.
Fuel Type And Flexibility
- Natural Gas Vs. Propane: Confirm your home fuel supply and whether conversion kits are available. Dual-fuel units provide flexibility if fuel availability changes.
- Supply Infrastructure: Ensure gas line capacity and pressure meet the BTU demands. Larger BTU units may need professional gas line upgrades.
Controls And Convenience
- Thermostat Control: Automatic cycling maintains set temperatures and can improve comfort and efficiency.
- Remote Operation: Remote controls with LCD screens add convenience for ignition and mode switching; check for standing pilot requirements.
- Manual Adjustment: Manual flame controls allow fine tuning of visible flame and heat output.
Installation Format And Aesthetics
- Free-Standing Units: Portable and easier to place; may still require safety clearances.
- Inserts And Mantles: Designed to integrate into an opening and can include decorative mantles or trims for a built-in look.
- Log Sets: Available vented or vent-free; check compatibility with existing burners and fireboxes.
Safety, Ventilation, And Regulations
- Clearances And Combustible Materials: Follow manufacturer clearance specifications to walls, ceilings, and furnishings.
- Carbon Monoxide And Combustion Byproducts: Vent-free units release some combustion products into the room. Install CO detectors and ensure adequate ventilation, especially in tightly sealed homes.
- Local Codes: Verify local building codes and HOA rules regarding ventless appliances before purchase.
Durability And Materials
- Logs And Liners: Look for hand-painted ceramic fiber or refractory ceramic materials that retain detail and resist thermal degradation.
- Control Electronics: Remote receivers, thermostats, and ignition components vary in robustness. Check warranty and serviceability.
Maintenance And Operating Costs
- Routine Inspection: Annual inspection by a qualified technician is recommended to verify gas connections, burners, and pilot assemblies.
- Fuel Efficiency: Vent-free units often advertise high efficiency, but actual cost depends on local gas rates and run time.
- Replacement Parts: Confirm availability of logs, burner parts, and replacement controls for the selected model.
Comparison Perspectives
- Performance-Focused: Compare BTU output, thermostat control, and dual-fuel flexibility for heating effectiveness.
- Aesthetic-Focused: Evaluate log realism, mantle finish, and visual options like liners or doors to match décor.
- Regulatory-Focused: Prioritize vented options or compliant ventless units based on local restrictions and indoor air quality concerns.
- Installation-Focused: Consider whether you need a freestanding unit, insert, or complete mantel system and the complexity of professional installation.
