Want something to put in the van to stop it freezing overnight, saw this on Facebook marketplace but can’t see what make it is. It’s a diesel air heater

[High-Tower]

It’s just a generic Chinese heater, hundreds of them on eBay. There’s a useful Facebook group if you need help choosing one and getting it set-up. ‘Chinese diesel heater uk’

I've got one,works a treat, takes about 5 liters of diesel and I use about  1.5  liters a night depending on settings.
Safer than using eletric fan heaters.

Just doing some research on these and I have a diesel tank in the back of the van to feed my jetter, so could use this to fuel the heater , so I don’t need this type of heater with a built in fuel tank.

As a sideline question...... I have a hot washer in my van,  if I fill my 450lt water tank with hot water would this act as a radiator  and keep the inside of the van above freezing through the night?
