Rex Nordic heaters use a patented oil burner with an electric fuel pump. Combustion gases circulate through ceramic-coated pipelines inside the unit, generating infrared (radiant) heat that warms objects and people directly rather than just heating the air. This makes them highly efficient in draughty or open environments.
No. Complete combustion inside the unit means no separate exhaust piping is required in most working environments such as garages, workshops, warehouses, marquees, and terraces. Exhaust piping is only necessary if the heater is to be used in sleeping quarters or spaces with very limited ventilation.
Use standard #2 diesel or renewable diesel (HVO/R99). Below 50 °F (10 °C), switch to winter-grade diesel to prevent fuel gelling and ensure reliable ignition.
Rex Nordic heaters operate at approximately 48 dB, which is comparable to a quiet office or normal conversation. They are designed to be unobtrusive in working environments.
Rex Nordic heaters are equipped with automatic shut-off systems that activate if the unit overheats, tips over, or detects a fault. Units sold in the US and Canada are cETLus-listed for North America.
After a power outage, the heater restarts automatically in the same operating mode it was in before the power cut. All settings are stored in non-volatile flash memory, so no manual re-programming is needed.
Yes. Rex Nordic heaters feature an LED control panel and a remote control as standard. WiFi-enabled models can also be controlled via the Rex Nordic App (available for Android and iOS), allowing you to adjust temperature and settings from anywhere within range.
Fuel consumption varies by model and heat setting. As a guide at full output: the AH-210i uses about 0.25 gal/h, the AH-310i about 0.30 gal/h, and the AH-810i 0.50–0.58 gal/h. The thermostat cycles the burner once your space is at temperature, so real-world consumption is typically lower. Refer to the product manual for full data.
A mild odour may occur during the initial start-up and shut-down cycle due to brief periods of incomplete fuel atomisation. This is normal and not hazardous. During steady operation, a properly maintained Rex Nordic heater produces no noticeable odour.
Yes. Annual maintenance is mandatory for the warranty to remain valid on Rex Nordic heaters. This service includes replacing the oil filter, nozzle, and gaskets. Rex Nordic recommends using authorized service partners. Maintenance kits and spare parts are available from our North American warehouses.
Rex Nordic heaters come with a standard 2-year warranty. Register your product at warranty.rexnordic.com within four weeks of purchase to extend your warranty to 3 years free of charge. Note that annual maintenance is a condition for warranty validity.
