A 2,625 ft² car repair workshop with 20-foot ceilings is not the easiest space to keep warm in a harsh winter. Concrete walls, a partially insulated sheet-metal roof, and a frequently opened overhead door let heat escape easily. With a Rex Nordic diesel space heater, the hall holds a steady 60–63 °F all winter.
Owner Janne Mukkala has used the heater for six years — and wouldn't switch. “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-fired heater that backs up the main heating in freezing weather
Before the Rex Nordic heater, the shop's temperature fluctuated all winter. The building's main heating alone wasn't enough when the overhead doors opened in sub-zero conditions. The 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,” Mukkala says. “It reacts quickly to temperature changes and supports the main heating system.”
An energy-efficient heater like this is an excellent choice for garages or workshops that need efficient, odor-free heat without complicated installation. Here it's used daily through the winter, sometimes overnight.
Easy to use and built to last
The Rex Nordic AH-810i infrared heater has run in the shop for six years without a single service call. “I've never had to do anything to it — it just works.” Thanks to its advanced oil-burner technology and simple design, it's nearly maintenance-free, running quietly and odor-free with no smoke or fumes indoors. We still recommend the annual service kit to keep performance and efficiency year after year.
A satisfied user — warm workshop, minimal effort
Simple, reliable and economical is how many Rex Nordic customers describe these infrared heaters. “It has been the most reliable heating solution we've ever had,” Mukkala says. It complements the main heating and keeps the workshop warm all winter, even with imperfect insulation and doors opening frequently.
Who is the Rex Nordic diesel space heater for?
It's ideal for garages, repair shops, warehouses and workshops — any space that needs efficient heating and ease of use. It moves easily wherever warmth is needed, and performs reliably where electrical power is limited or traditional heaters fall short.
