- Controls and thermostats: Look for adjustable heat settings and reliable thermostatic control to maintain comfortable temperatures without wasting fuel.
- Installation compatibility: When selecting replacement ODS assemblies, verify model compatibility with your heater brand and model number to ensure proper operation and safety.
- Safety features: Tilt switches, protective grilles, and tip-over protection are important for preventing accidents in occupied spaces.
- Portability vs. permanence: Decide between portable units for temporary warmth and wall-mounted/infrared options for permanent room heating needs.
- Maintenance and replacement parts: Availability of replacement ODS assemblies, thermocouples, and service parts affects long-term reliability and uptime.
