- Safety features: Select units with tip-over protection, overheat shut-offs, and sturdy casters for mobility, especially in homes with kids or pets.
- Mobility and placement: Consider models with wheels or carrying handles for easy relocation between rooms or under desks.
- Maintenance: Oil-filled heaters require minimal maintenance, but ensure the unit can be emptied or serviced if needed for extended longevity.
- Remote controls and smart features: Remote operation and digital controls provide precise temperature management and scheduling.
