    I am currently in the process of trying to convince Nikki that we [STRIKE]need[/STRIKE] [STRIKE]want [/STRIKE] [STRIKE]must have[/STRIKE] one of these to remain married.

    Any how, I think its a battle that I can win as they can save money :whistle: and will be very useful for our winter holidays.

    I have had a look at the fitting advice and think I could probably handle most of it my self. Im not keen on T piecing in to the van fuel line so may just nip it up to my friendly garage to do that last bit having done all the other work myself.

    A couple of questions though. I think I would like to pipe it in to the already existing ducting as that travels nicely around the van. However, I will probably offer it a new ducting in to the cab area of the van as this gets really cold in the winter and in fact almost unuseable area of the van when we are skiing.

    Is it ok to pipe it in to the existing pipe work? I am sure Im not missing anything? im sure a couple of T pieces added would be fine.

    Does anyone know the fuel consumption of one of these units? and the power drain from the batteries for the fan?


    If any one has or knows of one for sale, I would be happy to receive a PM from you. :thumb:


    I would really like to here the thoughts of those that own one as well please. Especially in terms of noise.

    Many thanks

    Thanks aba,

    Never really thought of doing it that way as that would mean carrying spare diesel around presumably in a jerry can, which I do for the Genny so not that fussed.

    But what would the running time be? how long would it run for on 10L of fuel?

    thinking about it, its certainly not the best way I dont think, just another way.... for £55 im sure my local garage would stick me in a t piece, and I have no idea where to get red diesel from.

    Keep us informed mate as I'm thinking along the same lines, I would also add a pipe into the engine bay for the skiing trips.
    I've been doing some research on these and would probably go with Webasto seems to get better reviews than Erberspacher. Biggest problem I forsee is battery life I reckon 3 deep cycle is the answer don't think my 2 standard leisure would handle it. In fact thats 1leisure now as I ruined one recently now wont hold a charge.

    Hi

    Have you looked at http://www.eberspacher.com/products/air-heating/
    With mine I recon it uses about a litre in 3 to 4 hours. I have a battery monitor fitted and notice it using around 9amps on start up and also for a short while on shut down. It is using less than an amp when running. Mine is a small van and it does seem very effective.

    Hi Paul, As you know we have one in the RMB and its great. On the lowest setting the van is kept at 20 deg plus. They are a little noisy outside by the exhaust but inside its quiet. Its not piped into the gas piping and just has one blower duct in the lounge which is more than adequate. Its wired into the engine battery for some reason, and I must admit this was a worry at first, but having left it running overnight at home it used 6amps in a 10 hr period, so no worries there. If the battery drops below a set level it will not fire up, so you are always able to start the engine. Once the initial start up has happened it uses very little 12 volt power. The running costs are vertualy zero compared with running gas all night, more so for me as mine runs happily on bio diesel from the main fuel tank. If I was fitting one as an after market job I would consider fitting a small dedicated fuel tank and running it on red diesel, then it would cost next to nothing to run. You will wonder how you managed without one once fitted. There are several on ebay and there is a guy at Middlewich boats which is close by who is a trained fitter and does a service cheaply. There is not much really to go wrong with them and youtube has several good videos showing how to fit and service them. IMO if you are winter using your van as you do, they are a must have.

    just had another thought on this...

    if you have a common rail diesel you wont be able to just tee in to the fuel pipe because of the lift pump in the tank for 2 reasons 1. it may not allow the passage of fuel when engine off
    and 2. when the engine is running it may overpressure the eberspacher fuel pump.

    so if you are going down the route of using your road fuel you will need to remove the vans fuel tank and fit one of these. http://www.ebay.co.uk/itm/FUEL-TANK...tEquipment_Accessories_SM&hash=item3cc0034d14

    as for the noise the exhaust is the noisiest bit but you can get a silencer for them http://www.ebay.co.uk/itm/EBERSPACH...ervan_Caravan_Accessories&hash=item4165b4c1e5

    mate...dont you think it would be easier getting a proper van or could you not just run the hairdryer off the soon to be installed inverter?:getmecoat:

    now for the serious bit. I had a problem with one of the blown air outlets, its on a long run and the air gets cold by the time it comes out.

    So after doing some searching etc found that it was mainly down to the output of the heater - which is quite a good piece of kit but it seems the vents need to be balanced. our heater has 4 main outlets that all the pipe work is connected to. To make them all work equally i have to go around and mess about with the vents to get the balance right

    So, by adding in another vent may cause you a problem with too many outlets off one run and they will lower the pressure to the rest...and reduce the overall effectiveness of the system so beware you might get a good kickin from the boss if it gets worse after shelling out loads a wonga:BigGrin:

    Hi Paul (happy belated birthday) these units (2 and 3 outlet) are regularly for sale in the boating world as they are without doubt the most common heating units in the marine world.

    They run off the engine fuel supply because of course the boat fills its tank with red diesel.

    You could as already suggested run it off a separate tank if that is convenient.

    They are slightly more noisy than a Trauma running at full chat, but of course they do chuck out a considerable amount of heat.

    The difference between the various manufacturer doesn't vary much in electrical power usage so be sure to check out Webasto as well as Eberspacher.

    My Pal purchased his first unit (2 outlet) at Beaulieu Boat Jumble for £200 and it is still working today 16 years later.

    You can also get them to heat water these days, very good units. :thumb:

    best place to fit it would be centre of the van or as close as possible to the middle then pipe equal lengths of ducting to the front and rear.
    simple and balanced.

    Have read all three of Aba's posts and they all make a lot of sense, especially the common rail diesel one. The working pressure is far too great to Tee in to.

    Hi Paul

    In VT last year over the 6 days, our Webasto burned about 15 litres. That was for heating AND water.

    The temperature in the van was a constant 20 degrees C.

    With reference to the red diesel suggestion, if you want to become an expert at burner insert changes, then go ahead!

    It is well known that Webasto and Eberspacher will reject warranty claims on units run on red due to the increased fouling.:Eek!:

    A seperate tank is definately the way to go, forget red diesel they will run on central heating fuel even cheaper and no chance of running your main tank dry. . Smudger has a couple fitted in his conglomeration giganticus. An outboard motor fuel tank in a locker did the job for him and they kept us as warm as toast in the snow when we went to Portugal a couple of years back. I can't remember the fuel consumption except to say we were surprised how little it used. no problem using the existing ducting and adding a few extra outlets. Smudger had his fitted under his driving seat. I don't think he bothered with blown air ducting the output is so great there was no need. I found it quiet though others who are not deaf like me might find otherwise. The system is far superior in output to a gas fired jobbie. given the amount of time you spend in the snow I think that should be upgraded to a Must have. They are not cheap though. fitting yourself is a possibility but I would advise against it as insurance companies would run rings around you if it ever caused a fire. Heat and fibreglass don't mix well.

    thanks so far.

    I have sort of located one, and Nikki is getting keen on the idea, told her she could dry her hair with one :Wink:

    Thinking about it, I think the best method may be using the external tank and fitting that somewhere especially if problems are caused to the normal van running.

    so much to think about on that.

    The place to fit is almost in the middle of the van, under the front seats, that way I can pipe to the cab and then to the bathroom. It doesn't really need to go any further than that.

    If I never had to T piece in to the fuel line of the van then I could probably fit it all my self. :thumb:

    Am also told the early model D1 is more forgiving to alternative fuels and less problematic.

    good point on the hair drying use all you need is a T in the outlet pipe and a bit of vacuum cleaner hose and bingo 1 hairdrier.

    Just remember to make sure your new heater doesn't draw fuel from the bottom of you fuel tank!
    When your heater stops it will be nice to have some diesel left to get to the fuel station!!:thumb:

    As Roger suggested a 20/25 litre outboard engine plastic tank would be ideal. It has the fittings already there and is cheap to buy. Should last you on a ski trip and is lightweight.

    Why ???. If its bolted down and secure why would they ban you from the tunnel. I have a 110 litre tank as an extra and am not banned from anywhere.
