Buying Guide: Gas Wall-Mounted Heaters For Bathrooms
What type of gas heater is best for a bathroom? Direct-vent models expel combustion byproducts outside, offering safer operation in indoor spaces. Vent-free models provide more flexible placement but require room ventilation and are subject to local codes. Choose based on bathroom size, ventilation, and whether you prefer natural gas or propane.
Key considerations
- Room size and BTU needs: Larger bathrooms need higher BTUs. Match BTU output to space for efficient heating.
- Ventilation and code compliance: Vent-free units must meet local ventilation requirements. Direct-vent units typically require exterior venting.
- Fuel type: Natural gas vs propane. Propane units work where natural gas isn’t available but require LP supply access and storage.
- Mounting options: Wall-mounted units save floor space and simplify installation in tight baths.
- Safety features: Look for sealed combustion, electronic ignition, and built-in regulators. Consider automatic shutoff and overheat protection.
- Thermostat control: Thermostatic control helps maintain steady comfort and can improve energy efficiency.
Installation reminders
- Follow manufacturer instructions and local codes for venting and clearance to combustible materials.
- Ensure proper clearance above tubs or showers and avoid obstructing exhaust paths.
- Professional installation is recommended for gas connections and venting work.
