How much space will the Mecale 2kW heater warm?

The maker rates it for 108 to 161 sq ft, roughly a van cab, a truck sleeper or a small cabin. Larger spaces will take longer to reach temperature and may need a second unit.

Can I start it before I get to the vehicle?

Yes. Pair it over Bluetooth and preheat from up to 98 ft away, then set the target between 46 and 96.8 F. The 32 ft remote and LCD panel work when the phone is not at hand.

Does it work at high altitude?

It adjusts itself automatically at elevations up to 18,045 ft, so mountain passes and high campsites do not need manual tuning. That is a step up from heaters that require a separate altitude kit.

How long does the 10 L tank last?

At 0.12 to 0.26 L per hour, the tank runs up to about 38 hours at the low end. Expect shorter runs when the heater works hard in very cold weather.

What comes in the box?

The heater, the 32 ft remote and the LCD display are listed. Check the listing for the mounting plate, fuel line, exhaust and ducting, since those parts are needed for installation.

Is it safe to leave running overnight?

It has overheat protection at 518 F and constant temperature control, but it burns diesel and must be installed with the exhaust vented outside. Follow the maker's clearance and venting instructions.

Our take on the Mecale 2kW Diesel Air Heater with Bluetooth App and LCD Display

The Mecale is a 2 kW diesel air heater for vehicles and small spaces, sold with Bluetooth app control, a 32 ft remote and an LCD display. It claims to warm 108 to 161 sq ft in about 10 minutes and to run up to 38 hours on its 10 L tank. Automatic altitude compensation up to 18,045 ft and overheat protection at 518 F set it apart from basic diesel heaters that need manual altitude tuning. It suits van, truck, RV and boat owners who want a warm cab before they get in, though it is a combustion heater that needs proper exhaust and intake routing.
