What size heater do I need for my space?

As a general rule, you need approximately 100W per square meter for well-insulated spaces, and 150-200W per square meter for poorly insulated areas like workshops or warehouses. For example, a 3,000W heater is suitable for a 20-30m well-insulated room, while a 9,000W unit can heat a 60-90m workshop. Contact us for personalized recommendations.

Are DAHTEC heaters safe for indoor use?

Our electric and ceramic heaters are safe for indoor use. They produce no emissions and include overheat protection and tip-over switches. Gas and diesel heaters require proper ventilation and are designed for well-ventilated spaces, construction sites, or outdoor use. Always follow the safety instructions in the user manual.

What is the difference between ceramic and standard electric heaters?

Ceramic heaters use PTC (Positive Temperature Coefficient) elements that self-regulate their temperature, making them more energy-efficient and safer. They heat up quickly and maintain a consistent temperature. Standard electric heaters use resistance coils and are typically more powerful per unit size.

How do I choose the right dehumidifier capacity?

For basements and small rooms (up to 50m), a 30L/day unit is sufficient. For larger basements, warehouses, or flood recovery, consider a 50L/day or 70L/day unit. For server rooms and industrial applications, the 30L/day industrial model with continuous drainage is ideal.
