Warmth that stays – Airrex heater keeps the workshop comfortable all winter
Keeping a 244 m² car repair workshop warm in winter is no simple job, especially with six-meter-high ceilings, concrete walls, a partly insulated sheet-metal roof, and a door that opens constantly. In Finnish winter conditions, heat escapes fast. With an Airrex diesel space heater, the indoor temperature stays at a steady +16–17 °C throughout the winter. Janne Mukkala, owner of JM-Konehuolto Oy from Finland, has used his Airrex for six years – and wouldn’t switch to anything else. “The heater has worked flawlessly. When the door opens and the temperature drops, it starts automatically and brings the heat back quickly. Reliability is what I value most.” A fuel-powered heater that supports district heating in freezing weather Before installing the Airrex unit, the workshop temperature fluctuated constantly during the winter. District heating alone wasn’t enough to keep the workspace warm, especially when the overhead doors were opened in sub-zero conditions. The Airrex diesel heater provided the missing boost. “Now we can open the door whenever we need to without losing the indoor warmth,” says Mukkala. “Airrex reacts quickly to temperature changes and supports the district heating really well.” For garages and workshops where effective, clean heat is needed without complex installation, Airrex is an excellent choice. At JM-Konehuolto, the heater runs daily throughout the winter, sometimes overnight. Airrex – easy to use and built to last The Airrex infrared heater has been operating for six years without a single service requirement. “I’ve never had to do anything to it – it just works.” Airrex technology is designed with simplicity in mind. Thanks to its advanced oil-burning system and clean combustion, the heater is almost maintenance-free. It runs quietly and without odour, smoke or fumes inside the workshop. For best performance, we still recommend replacing the annual service kit to maintain efficiency and long-term reliability. A satisfied user – warm workshop, minimal effort Simple, reliable, and economical – that’s how many Rex Nordic customers describe the Airrex heaters. “It has been the most reliable heating solution we’ve ever had,” says Mukkala. Airrex complements district heating system perfectly, keeping the workshop warm all winter, even with imperfect insulation and frequent door openings. Who is the Airrex diesel space heater for? The Airrex diesel space heater is designed for demanding environments where consistent warmth, fast recovery, and ease of use matter. It performs exceptionally well in garages, repair shops, warehouses, and workshops – especially in spaces where doors open frequently and indoor heat is easily lost. Thanks to its mobility, the unit can be moved wherever warmth is required, making it a practical solution for busy work areas with changing layouts. It’s also a reliable option in locations with limited electrical power, providing steady, clean heat even when traditional heaters struggle to keep up.
