Is the Air Top 2000 STC worth it over a cheaper Chinese diesel heater?

Webasto brings dealer support, a documented 2 kW output and the SmarTemp 3.0 BT controller with Bluetooth scheduling. Budget heaters cost far less but often lack that control and parts network. At $1,295.00 at Amazon as of November 5, 2026, you pay for reliability and service.

How much diesel and power does it use?

It burns 0.12–0.24 L/h (0.03–0.06 gal/h) depending on heat stage. Electrical draw is 13–30 W on 12V, so a modest house battery runs it overnight.

What comes in the box?

The heater unit, SmarTemp 3.0 programmable controller, DP42 fuel pump with harness, 4.3 m electrical harness, 1 m stainless exhaust pipe and 0.5 m combustion intake pipe. An exhaust muffler is not included.

Will it fit a small van or camper?

The body measures 310 × 120 × 118 mm and weighs 2.6 kg, and it uses 60 mm ducting. Owners report it fits tight spaces like a Sprinter van.

Does it work at high altitude?

Webasto rates maximum operating altitude at 5,000 ft (1,500 m). Above that, combustion tuning or a high-altitude kit may be needed.

When is the price lowest?

Two stores list it new, with the best at $1,295.00 at Amazon as of November 5, 2026. Compare both listings and check the price history before buying.
