Frequently asked questions

Is 2kW enough to heat my van?

Yes for most builds. The 2000 PRO modulates between 0.9 and 2.3 kW and comfortably heats spaces up to about 20 m³ — a typical Sprinter, Transit, or Promaster conversion, truck bunk, or boat cabin — even in sub-zero conditions. For a large box truck or poorly insulated space, step up to the 4kW model.

How loud is it?

Quieter than the numbers suggest. In an independent bench test of the Aerolyn line, the reviewer measured 55 dB on low just one foot from the hot-air outlet — a bare, uninstalled unit in a 40 dB room — and titled the video "The Quietest Diesel Heater I've Ever Tested," calling the sound "a very pleasant white noise" he could sleep to. Installed in a vehicle — heater in a cabinet or under the floor, pump mounted remotely, intake and exhaust outside — typical in-cabin noise is around 45 dB, about library level.

How much diesel and battery power does it use?

Fuel: 0.10–0.29 litres per hour — a typical overnight run uses one to two litres. Battery: independent testing measured an average draw of well under 1 amp on low once running; the glow pin draws more only during the 2–3 minute start.

Does it work at high altitude?

Yes — automatic altitude compensation keeps combustion clean up to roughly 10,000 ft with no manual adjustment. This is a key difference from budget heaters, which typically run rich and soot up at elevation.

What's included in the box?

Everything needed for a standard install: the heater, WiFi (or Bluetooth) digital controller, mounting plate, exhaust system, 5 m fuel line with protective cover, air ducting, wiring harness, and fuel filter. No hidden "installation kit" upcharge.

Can I install it myself?

Most owners with basic tools can, in an afternoon, using the included plain-English manual and our step-by-step guides. Critical rule: combustion air intake and exhaust must be routed outside the vehicle.
