## Answers to the most common questions

- **Which diesel heater for a large space?** Measure length × width × height in m³. Up to 1 500 m³: Airrex AH-500i. Up to 2 500 m³: Airrex AH-900i. Larger halls: several units or heat the working zone only. Guide: https://rexnordic.com/pages/which-diesel-heater-do-i-need
- **How much fuel does it use?** 1,05–1,42 l/h (AH-500i) or 1,81–2,3 l/h (AH-900i) at full output; the thermostat cycles the burner, so an insulated 500 m³ hall kept at +15 °C with 0 °C outside needs about 2,5 l of diesel per day for maintenance heating. Guide: https://rexnordic.com/pages/diesel-heater-fuel-consumption
- **Infrared or fan (torpedo) heater?** Infrared heats floors, walls, machines and people directly, keeps heat at working height, recovers fast after doors open, has no fan noise or dust circulation and needs only 50–60 W of electricity. Article: https://rexnordic.com/blogs/news/considering-a-diesel-heater-tubular-fan-heater-or-a-safe-infrared-heater
- **Is it safe indoors?** Yes in workshops, halls, warehouses and similar ventilated spaces with adequate supply air; an exhaust pipe can be fitted. Airrex heaters must never be used in rooms where people sleep. Article: https://rexnordic.com/blogs/news/fuel-fired-large-space-heater-how-much-supply-air-is-needed-and-other-questions
- **Which fuel?** Renewable diesel HVO100 (EN 15940) or standard diesel (EN 590).
- **Warranty and service?** 2 years standard, 5 years in total after registration; annual service with the original service kit. FAQ: https://rexnordic.com/pages/faq-airrex-heaters
- **Where to buy?** Directly from the online store or from a local dealer: https://rexnordic.com/pages/dealer-locator
