Consider the size and insulation of the space. Check power output (kW), airflow (m³/h), number of heat settings, and whether it has a thermostat and overheat protection.
A powerful 3–5 kW unit can quickly heat garages, workshops or site huts. In poorly insulated spaces, heat may escape fast, but as a spot heater it works very well.
Heating needs are typically 60–100 W per m² depending on insulation. A 20 m² insulated room may need 2 kW, while larger or drafty areas require 3–5 kW.
Clean air inlets and the fan regularly to prevent dust buildup. Check the power cord for damage and avoid using the heater in damp areas unless it's IP-rated.
Yes, for temporary and flexible heating it’s simple, quick, and safe. For larger spaces or continuous use, a heat pump or diesel heater may be more energy-efficient.
