The Webasto Air Top 2000 is a 2kW diesel heater, the main competitor to the Eberspächer Airtronic D2.

Verdict

The Webasto Air Top 2000 is an excellent heater and slightly cheaper than the Eberspächer. Servicing is slightly harder in remote areas.

Specs

  • Power output: 0.9-2.0kW (modulating)
  • Fuel: Diesel (from vehicle tank or separate tank)
  • Voltage: 12v
  • Fuel consumption: 0.12-0.27 L/hr
  • Power draw: 0.5-3A
  • Noise: 32-45 dB

Running Costs

At 1kW output (typical UK autumn night), the heater burns 0.16L/hr of diesel. Diesel at £1.50/L: £0.24/hr. Running 8 hours overnight: £1.92. A tank of fuel lasts 2-3 weeks of winter use.

Reliability

Webasto heaters are generally very reliable. Common issues: failed glow pin (every 2,000 hours), carbon build-up from running on low for long periods.
