Buying Guide: How To Choose A Gas Parlor Heater

Selecting the right gas parlor heater requires careful consideration of room characteristics, installation constraints, fuel type, and safety marks. Below are key factors to compare and verify before purchase.

Room Size And BTU Output

• Match BTU To Room Size: Estimate square footage and choose a heater with appropriate BTU capacity. Smaller parlors (100–500 sq. ft.) typically need 5,000–15,000 BTU; medium rooms (500–1,400 sq. ft.) need higher output models up to 30,000 BTU.
• Ceiling Height Matters: Higher ceilings increase volume and heating needs; select models with higher output or supplemental circulation.

Venting Requirements

• Vent-Free (Ventless) Units: Provide easier installation and steady convection heat but require adequate room ventilation and adherence to local codes.
• Infrared vs. Blue Flame: Infrared (radiant) heaters warm objects and people directly; blue flame (convection) heaters warm air and distribute heat throughout the room.
• Local Codes: Check local building codes—some jurisdictions limit ventless gas heater installation in certain rooms.

Fuel Type And Availability

• Natural Gas vs. Propane: Choose based on what gas service is available. Some units are natural gas only; portable models often use propane.
• Conversions: If conversion kits are offered, confirm manufacturer guidance and professional installation requirements.

Controls And Features

• Thermostat Control: Built-in thermostats allow better temperature regulation and energy efficiency.
• Ignition Type: Electric ignition provides automatic start; piezo/manual ignition allows operation without electricity.
• Mounting Options: Wall-mount, floor-mounted with base feet, or portable options affect placement flexibility.

Safety Systems

• Oxygen Depletion Sensor (ODS): Shuts the unit off if oxygen levels drop—critical for ventless appliances.
• Tip-Over Switch: Important for portable units to prevent operation if the heater falls.
• Clearance Requirements: Review minimum clearances from combustible materials and floor height recommendations.

Installation And Clearance

• Professional Installation: Hard-piped units and natural gas wall heaters often require licensed installer work and adherence to local code.
• Clearance And Location: Check manufacturer-specified clearances from walls, floors, and ceilings to ensure safe placement in a parlor.

Operating Cost And Efficiency

• Fuel Consumption: Higher BTU output increases fuel usage. Consider thermostat control to reduce runtime and save fuel.
• Heat Distribution: Infrared units can feel warmer at lower operating temperatures because they heat objects directly, which may reduce runtime.

Maintenance And Durability

• Service Access: Choose units with accessible controls and service points for routine maintenance.
• Warranty And Support: Review warranty terms and brand support options.

Comparison Perspectives

• Small Parlor Use: Compact blue flame units around 10,000 BTU or portable propane heaters with tip-over protection suit smaller parlors.
• Larger Parlors Or High Ceilings: Consider 30,000 BTU blue flame or infrared models for broader coverage and faster heat-up.
• Ventless vs. Radiant: Ventless blue flame provides consistent ambient heat; infrared radiates warmth to occupants and objects, often perceived as quicker warmth.

Before purchasing, confirm product specifications and installation requirements directly from the manufacturer and verify local code compliance for ventless gas appliances in living areas. Professional consultation is recommended for natural gas connections and fixed installations.
