Is the Jacgood diesel heater worth it at $84.99?

At $84.99 at Amazon as of November 5, 2026, it is one of the cheapest complete all-in-one kits. Budget for a CO alarm and careful exhaust routing, since it has no NRTL listing or written warranty.

How long does the 5L tank last?

The listing claims up to 48 hours, which only holds at low output. At full 5 kW expect roughly 10 to 12 hours, since a diesel heater burns about 0.4 to 0.5 L per hour at that level.

Can I use it in a car or small van?

Yes, but 5 kW is a lot for a small space. Run it on the low setting and make sure the exhaust goes outside and a CO alarm is fitted.

What comes in the box?

The heater unit with its 5L tank and LCD controller, a remote control, and the usual wiring and fuel line parts. Check the listing for the exact kit contents before buying.

Does it need a 12V supply?

Yes. It runs on 12V DC and draws several amps during startup, so connect it to a battery that can handle the load, not a small power adapter.

Diesel heaters usually drop in late summer and early fall, before cold weather demand. The current $84.99 at Amazon is already near the bottom of the market.
