Interesting comment on the discussion via the previous link from robmac ... the heaters not destined for Europe originally wouldn't pass the tests that would allow them to be CE marked - so the eBay jobs suitability would be suspect. And when sold in UK by PlanarUK (think that is the company?) after suitable mods to gain CE approval, the price benefit is (IMO) severely erroded.
That is how I am reading it anyway. Looks like more money heading to PF Jones for a D2 Airtronic.
Is that what the thread linked to by Robmac says?
I thought otherwise and can't find any mention of modifications to meet CE standards. It costs a lot of money to have such items tested and certificated so it is quite possible that the Chinese makers simply have not bothered to invest in that. On the whole I thought that link contained comments both for and against the cheap Chinese heaters and would not put me off.
The question for me is are the established makes actually better and if so are they better by a sufficient margin to make them worth the extra cost? I am not really bothered by the suggestion that one might raise the value of the vehicle by fitting an established make, seems unlikely to me.

Aux Heat thoughts – Oct 2016
http://www.defendersource.com/forum/f48/aux-heat-thoughts-73769.html
I have been curious about the name Espar, used in North America:
“The year 2016 marked the 150 year anniversary for Eberspaecher and Espar is very proud to announce that we will officially assume the Eberspaecher name in the marketplace, while still maintaining "Espar" as a legal business entity.”
If one is not willing to risk an import from China with perhaps little chance of service support the options seem to be:
1. Used but tested Eberspacher or Webasto heaters from about £350 upwards. With more or less installation kit, ducts etc so depending upon installation required may end up costing nearly as much as a new Planar kit.
2. A new Planar 2D from the official UK Supplier
www.planarheaters.co.uk for just below £500. Seems to come with a fairly comprehensive installation kit although their web site is poor and lacks clarity. Autoterm in Germany have a better web site, charge about the same and will send to UK.

3. A new Eberspacher Airtronic D2 Heater Kit from PF Jones for £650.

Has anyone found a better offer?
A simple oil burner, compact and quiet the diesel equivalent to the old gas fired Carver SB1800, could be interesting but have not seen anything suitable yet. Does such a thing exist?
