    I have seen on Ebay 300w electric heaters has anyone tried these. I know the 150w dashboard mounted ones are useless.

    Be careful as that unit requires 25amps.

    The average cig lighter is only rated at 20amps which means a maximum of 240watts unit. That said, a sepaerate cable and fuse could easily be put in.

    Ratty, are these good? as I was thinking of getting one for mine as it has no heater box at all (71 lwt truck cab). I can cope in the summer but winter will be a different story

    No issues in running a new cable from the battery with an isolator and fuse on it

    Mine came with ring connectors on it

    In -5 to -15 deg C temps my landys standard heateris just about acceptable when moving. It struggles to blow out even luke warm air if it's on tickover although it

    The leccy heater takes a little while to heat up the inside of my landy from 'icebox' status but once it gets up to temp it's capable of keeping it warm. It does make a big difference in de-icing my windscreen too.

    I had it mounted behind the front seats and pointing at my windscreen on my previous 110. It could defrost the screen in just a few minutes.

    On my current 110 it's located behind the second row seats so doesn't defrost the windscreen anywhere near as fast.

    Instead of heating the screen to defrost it as it used to with my previous 110, it heats the interior of my landy which in turn gradually defrosts all the landys windows. Coupled with the standard heater it does make a big difference though.

    Hi Ratty, that's the one I was looking at. Are they any good? I have seen them on Ebay for about £79/80.
    Oh, just seen the rest of your comment. I take it you think they are a worth while investment then. I have the same problem, my Landy takes ages to warm up and when it is really cold ( -12 to -18 here) Heat only starts to come out of the heaters when I arrive to where I am going. I am going to fit a Kenlowe fan and remove the Viscos one, I am hoping that might help also.

    Hi Bigsi, I have looked at Webasto heaters but they seem very expensive and more complicated to fit as you need an exhaust vent and a link up to the diesel fuel tank. Finding somewhere to fit it is also a bit of a problem as you need air to circulate. I have a Webasto heater fitted in my Sprinter van. You have more room to play around in there. That one cost over a grand. I was hoping these electric ones for about £75/80 might do the job.

    I am just wandering if my Alternator will cope with one of these electric heaters and the two 100w spots I have on the front?

    its your thermostat not fan that controls warm up ,electric fan heaters arent much cop,there a lot of energy needed to produce heat fuel burning one is the only real way

    Yes you should be fine - I have a similar set-up and when parked up leave the engine on tick over - never had a a problem and still on my original LR battery after 8 years and 120,000 miles

    I use mine through the winter time connecting via the battery itself. It has the round lugs with a fuse, to attach by screws to the terminals. I rigged up some flexible heating ducts to heat the dreaded sides windows on 1988 CSW. Seems to work well and faster when directing the heat source. I tried to copy the Arctic heater used on the lightweights vehicle.

    Have just bought a 200w unit for use as an overnight heater, or at least a Pre heater.

    It has a 3 hour timer fitted which is handy.

    I have a twin battery setup so the idea is to set the fan up an hour before bed then leave it on for a little while after, maybe 30 mins (I have a bed setup in the car)

    Obviously it is no problem to drain the secondary battery, I just hope that the heater will at least work at all to take the chill off, and that I will get a few hours without draining the battery completely flat, which is bad for battery health.

    My battery monitors are visible from the bed so I will be able to keep tabs on what the situation is.

    It hasn't arrived yet so will see later on whether it works at all (was 30 quid so I expect it to be half decent) and if it will suit my purpose.

    My batteries are over 70ah I think so even at 20 amps it should manage 1.5 hours easy!

    Use mine as a night heater when kipping in the back and as a secondary when it's really cold. Wired direct to aux battery. Does make a difference but wouldn't want to rely on it alone :eek:

    I have the same as Ratty hard wired (via a fuse) to the battery. Would be lying if I said it was hot hot hot, but does help the cab warm up quicker than the Landy's heater alone.

    Only use when engine is running so no battery drain concerns

    Hey SH ... hope you're well up there in Jockland.

    Do you not just wear more clothes up there when it gets cold?

    Having a heater must really emphasise you're a true southerner! ;)

    I have one of those Kenlowe preheaters (I think they are called "Kenlowe Hot Start") which is a lot like a kettle element that you plug into the mains via a cable and it heats up the water in your engine so that when you start up the system is already at running temperature and you get hot air through the vents. If your landy is within an extension lead of a 240v socket then its worth considering.

    I think the Kenlowe units are quite expensive but they are easy to fit (just inset them into the exisiting water pipe system). I have taken mine off as I was not using it so if you want it then feel free to make an offer. I think they go for around 100 quid on fleabay, send me a PM if you are interested....was probably going to post in the for sale section next week.

    When winter kicks in up here, I run a 240 extension on a timer switch out, plug in a small fan heater sittin on my cubby box set to come on about half an hour before I'm due to go to work. No frosty windows and cars are toasty. And a bit of cardboard over the rad doesn't go wrong too.:)

    The best way to get heat is to either use a rad muff to keep cold air off the radiator or to fit a hotter stat (I run a 75 in summer and an 88 for winter). In winter you can safely run the engine at a higher temp as the lower surrounding air adds a hell of alot of extra cooling...

    these muffs, was thinking of getting one, but what effect on power does it have? after all, your covering up the intercooler too.
