(Not used that site BTW, so cant vouch for it - just used it to compare prices/availability)
I've thought about going the separate tank route (diesel or gas) before I saw this heater, but I'm now just going to keep things simple and fit one for the existing fuel supply!

4Kw is a bit strong for our vans - you will be running it a low heat output for the majority of the time which can lead to premature coking. The best size for our vans is 2 - 3Kw then you can run them at full heat for all the time.
Unfortunately (fortunately for me

) Eberspächer do not make one this small any longer so the only choice is the Webasto Airtop 2000 (2Kw) or the older 3.2Kw (HL32 and Airtop32).
Consumption figures for Webastos:
Airtop 2000
Fuel consumption: through control range: 0.1 .. 0.2 kg/h (0.16 .. 0.27 l/h)PETROL, 0.1 .. 0.21 kg/h (0.12 .. 0.24 l/h)DIESEL.
HL24/32/Airtop32
HL24 B first, HL24D, HL32B, HL32D.
Mounting position is easiest where the factory fitted ones are as there is a nice clear access underneath. (Anywhere your ingenuity can fit it safely though.)
