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
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.

Warmth that stays – Airrex heater keeps the workshop comfortable all winter
A 244 m² car repair workshop with six-meter-high ceilings is not the easiest space to keep warm during Finnish winters. Concrete walls, a partially insulated sheet-metal roof, and a frequently opened overhead door allow heat to escape easily. Thanks to the Airrex diesel space heater, the hall maintains a steady temperature of +16–17 °C throughout the winter. Janne Mukkala, owner of JM-Konehuolto Oy from Finland, has been using the Airrex heater for six years – and wouldn’t switch to anything else. “The heater has worked flawlessly. It starts automatically when the door has been open and the temperature drops, and it quickly brings the warmth back. Reliability is what I value most.” A fuel-powered heater that supports district heating in freezing weather Before installing the Airrex, the workshop’s temperature fluctuated constantly during the winter. District heating alone wasn’t enough to keep the workspace comfortable, especially when the overhead doors were opened in sub-zero conditions. The Airrex diesel space heater provided the extra boost that was missing. “Now we can open the door as often as needed without losing the indoor warmth,” says Mukkala. “Airrex works as a fuel-powered supplementary heater that reacts quickly to temperature changes and supports the district heating system.” An energy-efficient heater like Airrex is an excellent choice for garages or workshops where efficient, odorless heat is needed without complicated installation. At JM-Konehuolto, the unit is used daily throughout the winter season, sometimes even overnight. Airrex – easy to use and built to last The Airrex infrared heater has been operating in the workshop for six years without a single service need. “I’ve never had to do anything to it – it just works.” Thanks to its advanced oil burner technology and simple design, Airrex is nearly maintenance-free. The heater operates quietly and odorlessly, without smoke or fumes inside the building. We still recommend replacing the annual service kit to maintain optimal performance and energy efficiency year after year. A satisfied user – warm workshop, minimal effort Simple, reliable, and economical – that’s how many Rex Nordic customers describe the Airrex infrared heaters. “It has been the most reliable heating solution we’ve ever had,” says Mukkala. Airrex perfectly complements district heating and keeps the workshop warm all winter long, even though insulation isn’t perfect and the doors are opened frequently. Who is the Airrex diesel space heater for? The Airrex diesel space heater is ideal for garages, repair shops, warehouses, and workshops – any space that requires efficient heating and ease of use. Thanks to its mobility, the unit can be easily moved wherever warmth is needed. The fuel-powered heater also performs reliably in locations where electrical power is limited or traditional heaters fall short.
