    Depends on insulation etc but my 4.5 kw heater copes fine with 7 or 800 sq feet standard height ceiling. My old workshop was 700sq feet with a 20 foot high ceiling and even a 40kw space heater did nothing.

    It was an option on TD5s so you may be able to find the wiring is already in place.

    Genuine units are very spendy, cheap Chinese one in the rear quarter

    Thanks Fizzy. I did some Googling:

    For a poorly insulated room it looks like 12.5W/sq ft (15W for cooler climates) for 8ft ceiling. Add 25% for every 2ft over 8ft ceiling.

    Obviously that's a room in a house, but you don't need a garage to be as warm as that, just to take the chill off.

    My garage is 40mm log cabin construction, almost 500 sq ft with shallow pitched roof....I might just have to try the 8KW to see how it performs.

    I bought one about 12 months ago cant fault it, cost about £170, Genuine Eberspacher is £700+. Campers toasty in 10 mins, one thing I noticed about the Face book group is a few people kicking off when its clearly a poor installation thats stopping it working, simple to fit even with my chinese instructions.
    I did a temp fitting with a petrol can but then fitted a boat fuel tank as I can now run it from Red or Kero which I felt was worth the extra £26 and fitting as it would be a pain to tap in to the van fuel line. Tank is now strapped in and vented through the filler cap to under the van, fuel is drawn through the small plastic dip tube

    @Kayos there were Webasto heaters fitted to other Land Rovers and also some of the Rover cars. Have 1 in my D3 and think it's about 5Kw, no remote and it kicks in when temp drops below 5c but I have acquired a GSM remote for it so I can get it warn and toastie by sending it a text.

    The D3 uses W bus protocol but you can buy a gizmo off eBay to activate it via a switch if retro fitting

    It's not a warn air heater but warns the engine coolant and circulates it

    That’s the sort I want rather than an air heater but the air ones seem a lot cheaper

    I think I may need to look into the jet kart a bit more also!!!

    I service both Webasto and Eberspacher heaters at work, there isn't a lot to them so I can easily see how the Chinese can knock out clones cheaply, My only concern with the cheap copies is that they are properly sealed so that the fumes can't leak into the heated air. Just to be on the safe side you should have a Carbon Monoxide alarm in the space that you intend to heat.

    I have just ordered an 8kw one - What temp does the hot air outlet reach? Will need to run ducting.

    Not sure off the top of my head, it's too hot to comfortably touch though. I'll try and find some specs in the service manuals we've got but I suspect it's not listed. IF I remember the next time I'm messing with one I'll stick a temperature probe on it and report back.

    The recommended ducting is aluminium stuff like what used to go between the plate over the exhaust manifold and the air intake on old carburettor engined cars to help them in cold weather.

    Well as I'm the UK service manager for Eberspacher best declare my colours !, air heater will add enough to burn if you leave your arm or leg in front of it ! Don't use an air heater direct on a windscreen!

    The chinese stuff is cloned in appearance however the materials used are not the same , horses for courses , but yet to see a European OEM use a chinese heater, the testing and validation before release to vehicle production takes considerable time and money, remember there are still plenty of Eberspacher D1L running and those are 20 years old minimum, wonder how many chinese heaters will be?

    We're generally a tight bunch on here, So might struggle to convince us to pay more! :laughing::scared:

    Of course the quality wont be the same. And they will need a lot more tinkering to work. I bet the heat output wont be accurate either - but I paid £135 for one - you could buy 6 or 7 for the cost of an Eberspacher. Would I use it somewhere critical? No! And if I forked out £80k for a Range Rover I wouldn't be impressed with a Chinese one either!

    Prices seem to go up in winter :laughing:

    Back in the summer you could pick up a Rover 75 or D3 unit to warm your coolant for about £70
