Buying Guide
- Space and heat needs: Calculate required BTU based on square footage, ceiling height, insulation level, and whether doors are frequently opened. Larger or drafty spaces typically need higher wattage models or multi‑stage heaters.
- Electrical requirements: Most 240V garage heaters need a dedicated circuit with appropriate wire gauge and a compatible breaker. Verify panel capacity and available amperage before selecting a model.
- Mounting and placement: Ceiling mounting frees floor space but requires proper clearance and secure mounting. Wall or floor installations offer flexibility in cramped layouts but can reduce wall clearance for tools or vehicles.
- Controls and efficiency: Look for thermostats, remote controls, and energy‑saving features such as ECO modes and programmable timers to reduce operational costs.
- Safety and reliability: Choose models with ETL or UL listings, overheat protection, and durable enclosures to withstand garage conditions and long service life.
- Maintenance and warranty: Consider ease of access for routine checks and the length and coverage of the warranty to assess long‑term value.
