Electric Fan Heaters vs IDF Heaters – What’s Best Temporary Heating Solution for Your Site?
Choosing the right temporary heater can dramatically impact safety, productivity and running costs on your site. Whether you’re heating a welfare cabin, warehouse, construction project or event marquee, the decision often comes down to two main options: electric fan heaters and indirect diesel-fired (IDF) heaters.
In this in-depth guide, we break down exactly how each heater type works, their technical specifications, ideal applications, pros and cons, and which environments they’re best suited for. From our compact 2kW electric heaters to high-performance 72kW MDA units, and our industrial 47kW–375kW IDF heater range, you’ll learn how to match the right heater to your space size, insulation level, power availability and heating demand.
Whether you need fast, fume-free heat for enclosed rooms or high-capacity, fuel-efficient heating for large industrial zones, this guide helps you choose the safest and most cost-effective temporary heating solution for your site.
