Terrace heater, hall heater and BBQ hut heater – Airrex AH-300
Harry Mäkelä has an impressive terrace in his house. Mäkelä uses his grill a lot in winter, so the Airrex infrared heater may be switched on from Friday until Saturday. “We used to use this duct-shaped fuel oil heater. We found its flame and blast slightly dangerous in terms of heating a BBQ hut constructed of log beams with a diameter of 20 cm. A few years ago, when my son acquired an infrared heater and put it by the door of a 200-square metre maintenance hall as a kind of an air curtain, I decided to get these devices for our personal use as well. In temperatures of 20 degrees below zero, we consume around one litre of oil per hour in the BBQ hut. The 2-storey terrace is 17 metres wide and 5 metres deep. One Airrex AH-300 heater is in the lower terrace and one is upstairs. When we had to start refuelling the old heater with fuel oil, the tank of the new heater, in comparison, remains almost half-full,” Mäkelä describes his experiences. In Mäkelä’s experience, an exhaust pipe is not necessary in a big terrace or even in a BBQ hut. The heater does not emit any smoke at all because the oil burns so cleanly. Switching off the heater only causes a small fizzling sound, after which you can smell fuel oil for a while. Mäkelä, however, reckons that the consumption and odour emissions of older Airrex infrared heaters could be reduced if at least their filters were replaced. The heaters have been used for 3–4 years without requiring any particular maintenance. “I can warmly recommend these heaters to everybody, I have been very satisfied with them,” Harry Mäkelä says, summing up his experience.

Flower friendly Airrex AH-300 infrared heater solves greenhouse heating problem
Three years ago, at the Munkkivuori Garden, it was considered how the premises would be kept warm and the flowers happy. The gas heater didn’t work, but the diesel-powered Airrex AH-300 was chosen as the right heating solution. The garden has a smaller store section and a larger greenhouse. The entire space is about 5 meters wide and 30 meters long. Initially, they purchased one heater, but very quickly they bought another to the store section. The product has been very easy to use and working perfectly. Now the company has even bought a third heater. – We have been very pleased with these infrared heaters. Two of them are constantly in use and the third is used when needed. On the greenhouse side, the heat is kept at just under ten degrees Celsius and then at the store again at 13-14 degrees Celsius, says store manager Aki Lahtinen. ”Cost-wise, I can say that Airrex is much cheaper than gas heaters” The AH-300 has a charm of comfort and the flowers are happy. The device is almost odorless and produces carbon dioxide, which is great in such an environment. The 15kW / h heating output is just optimal and the low fuel consumption has brought the desired cost efficiency. Workers do not have to worry about using the equipment, just refuel and let the heater do its job. – Yes, these are easy to use, all you have to do is refuel. In terms of cost, I can say that it is much cheaper than gas-fired heaters, says Lahtinen. The Airrex AH-300 has many things that make it easy to use in such spaces. It can be easily moved and does not require a separate exhaust pipe. It is almost odorless and does not make any noise. Infrared radiation heats the material instead of the air. No fan is needed so dust or other contaminants do not rise from the floor. All in all, the Garden has been very satisfied with Airrex heaters. The thermostat-controlled heater is set at the desired temperature and then everyone can concentrate on the essentials. Read more about AH-300
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.
