FAQs

How is a Nordkapp® heater different from a typical low-cost diesel heater?

European type approval

Nordkapp® Air and Cube road-vehicle heaters are engineered and laboratory-tested to the applicable UN ECE R122 and R10 requirements. Current approval documents are available on our Documents page.

Type approval is only one part of a compliant installation: the heater must also be installed according to its instructions and the applicable national, inspection and vehicle-specific requirements.

Control options

Control options vary by model. Gen 3 Air and Cube heaters are available with Bluetooth, Wi-Fi + Bluetooth or GSM 4G + Bluetooth control, while every version can also be operated from its physical control panel.

Warranty and support

Nordkapp® heaters include a 24-month warranty, with a 36-month warranty in Spain. Spare parts and support are available in Europe.

Installation components

Nordkapp® heater kits use purpose-selected fuel lines and installation components for the relevant heater model.

Quieter operation

Nordkapp® Air and Cube Gen 3 heaters include the SuperSilent™ fuel pump, designed to reduce the repetitive ticking noise associated with a conventional diesel-heater dosing pump.

What does ECE R122 type approval mean for a diesel heater?

UN ECE R122 covers vehicle heating systems and combustion heaters. A type-approved heater has been tested against the applicable requirements of the regulation.

For a compliant road-vehicle installation, the heater model and installation must also meet applicable national, inspection and vehicle-specific requirements. Current Nordkapp® approval documents are available on our Documents page.

What is the Difference Between GSM and Bluetooth Control in Diesel Heaters?
  • Bluetooth: local smartphone control near the heater without an internet connection.
  • Wi-Fi + Bluetooth: local Bluetooth control plus remote control when the heater is connected to an internet-enabled Wi-Fi network.
  • GSM 4G + Bluetooth: local Bluetooth control plus remote control through the mobile network using a compatible SIM card and mobile service.
How Much Fuel and Electricity Does a Diesel Heater Consume?
  • Fuel Consumption: Approximately 0.1 liters per hour per kilowatt of power.
  • Electricity Consumption: Around 40 watts.
What are the Common Uses for Diesel Heaters?

Diesel heaters are used in various settings, including vehicles, garages, cabins, camper vans, boats, greenhouses, and heavy machinery.

Can I Connect a Diesel Heater to Mains Electricity (220–230 V)?

What Size Area Can a Diesel Heater Warm Up?
  • 2 kW Heater: Suitable for 20 square meters.
  • 5 kW Heater: Good for 40 square meters.
  • 8 kW Heater: Can heat up to 60 square meters.
Can One Diesel Heater Warm Multiple Areas?

Yes, by using an Air Share Kitto split the airflow.

What is the Difference Between a Diesel Air Heater and a Liquid Heater?
  • Diesel Air Heater: Warms the air inside a space.
  • Liquid Heater with Water Circulation: Can heat both the engine and the interior of a space, such as in vehicles.
Can I homologate a Nordkapp® heater in Spain?

Nordkapp® Air and Cube road-vehicle heaters have UN ECE R122 and R10 type approvals. In Spain, the final installation must also comply with the applicable ITV and vehicle-modification requirements. You can find the current certificates on the Documents page.
