Common questions about Giantz Diesel Air Heater All-in-one 12V 5KW LCD Remote Control for Car RV Indoors 2025 caravan machinery
Is 5KW too much heat for a small van?
For a single-axle van, yes, on full noise. That is why it runs 1-5KW adjustable, and you will spend most winter nights near the bottom of that range with a window cracked. Bigger tourers and canvas campers are where 5KW earns its keep.
How many nights will the 5L tank give me?
A few nights if you idle it low, closer to two hard ones flat out. Fuel burn runs 0.2-0.5L/h, so the setting you choose matters far more than the tank size. Carry a jerry if you are heading somewhere cold and remote.
What has to be sorted before the first burn?
Three things: the exhaust must vent outside and away from windows, the 12V feed needs heavy cable straight to the battery because start-up pulls 15A, and a carbon monoxide alarm goes in the van. Skip any of those and you have a problem, not a heater.
