    Hi,
    Have any funsters had experience of diesel heaters?
    Are they good at the job? what is the cost of running these?
    Any major problems encountered?

    Sorry for all the questions, should ask the dealer but prefer to get feedback from funsters who have lived with them.

    Cheers
    Steve

    Yes but not good I'm afraid, we bought a new van last year and had lots of problems with it so the dealer had it back and fixed everything under warranty then two days later the diesel heater packed up and the dealer said they were not capable of repairing it and it would have to be taken to a specialist 70 miles from us. That was the final straw we got rid of that van and went back to a Rapido with gas /electric heating.
    I should also say that we found the diesel heater very noisy ! :Sad:

    If you want HEAT then you want an Aberspacher. I have had them in trucks for years and have one in my camper. Cheap to run and give out loads of heat. They can be a bit noisy outside the van, but if its cold enough outside to have a Aberspacher switch on inside, does it matter. A great bit of kit and a must for winter van users.

    We wouldn't be without our Webasto. It's not noisy , it's cheap , and it's very warm. No cold spots in our motorhome even in the depths of winter. The whole vehicle can be warm when you drive , if you want. Not just the cab. Ours isn't a dual top. It's the other version.
    When you turn it off it continues going and you can hear it then , but that's it servicing itself , I'm told. Also you hear the fan on start up , then it's silent. You can hear a ticking noise outside , but it's not loud .
    We didn't know , when we bought the van , how good it would be. But compared to the gas Truma ? Heaters we've had in caravans, no comparison at all.....
    When we eventually downsize to our PVC before we retire, we shall make sure we have diesel heating again. Until then we shall keep the first motorhome we have bought, because luckily for us , we got it right 1st time. :thumb:
    It ticks all our boxes.
    Unless we have unforeseen circumstances :Eek!: we shall have our mizzi a long time.

    I too have a webasto in my van, I would never heat my van with gas as its too expensive, if you are using your diesel for heating your gas bottles can last months :thumb:
    As for diesel usage, I use about a litre per night, my webasto uses 0.08 litres per hour, and this is only when actually heating, they have thermo stats so they aren't running diesel through all the time

    We have an Eberspacher diesel heater, it is fantastic. Turn up high to start, yes a little bit noisy but then turn it down to maintain the right heat and you don't notice it. Very effective. Haven't worked out the costs as yet.

    Have had a couple of eberspacher and was very happy with them running costs minamal,noise as already been said by others :Wink:presently got a gas truma e2400 blown air heater and quite happy with that as well.Also had a propex which is not as good the Truma did it's job and keept us warm :BigGrin:Noise does not really bother me while I am asleep so no problems there :Smile:When on hook up we have a thermostacicaly controled fan heater that compaired to all the above IS noisey but I take heart that I hear it switch on and off :BigGrin:When I don't hear it may be the time to worry or not as the case may be :BigGrin:

    Not sure if i should post a new thread for this but I have an Eberspacher Hydronic D5WS fitted as original equipment on a Mercedes Rapido. It warms up the Alde heating in the van really quickly via a heat exchanger. Not sure how economical it is yet but the only problem is that it only works when the engine is running. (difficult to tell how noisy....) Does anybody know if it is possible to re-configure this to run without the engine? Thanks

    Just change the electric feed cable to the leisure battery. Job done.

    should be possible with a decent sized battery Alan.

    running current is just over 3 amps (37 watts)
    startup current is just under 10amps (110 watts)
    water pump current is 1.25amps (16 watts)....but is included in the running current

    probably no more or even less than running a conventional blown air system.

    google these words exactly..... Eberspacher Hydronic D5WS specifications

    click on the first result, download the PDF and scroll to page 13...Technical data for diesel heaters

    gives all current and voltage data.

    why it has been connected to the engine electrics is a mystery unless the installer connected to the fridge supply.

    Strangely my Eberspacher is connected to the engine battery and will only go through the startup program if the engine is running or if on hookup. Once the startup program is complete I can switch off the engine and it runs fine.

    We'll never go back to gas.

    Ours is a Webasto Dualtop. Hot water and van, even on the move. No worries about exchanging gas bottles or looking for autogas.
    Good batteries are a must for off-hookup use though, as with any blown air heating.:thumb:

    Our experience pretty much reflects the above. And whilst we have not properly calculated the running costs, we feel it's pretty economical. Never notice the diesel going down in the tank as a result of having used the heater.

    One point we have to remember, however, and I'm not sure if others are the same - apparently, we need to have at least a quarter of a tank of fuel or otherwise it will not operate. Designed to avoid the risk of running the diesel dry and not being able to start the van.

    One other thing, we notice the lights flicker somewhat whilst the heater is 'firing up' - no doubt due to the heavy current drain. Perfectly, OK once up and running. Guess you need plenty of umph in the leisure battery, or alternatively run the engine to get the heater started, although we've never needed to do that.

    And as mentioned by others, our gas lasts for ages and ages as we're not using it for space heating. :thumb:

    Hi
    Not had one, but when on site you can hear next doors noisy. Pete :Sad:

    It might be worth rewiring the supply to your heater to stop the flickering lights.
    On ours, the entire left side of the van used a single neg connection. This continually eroded and loosened due to the excess current.
    A new supply, directly from the battery connection at the CBE panel, got rid of the flickering.
    This has been the case on at least one other Chausson I know of. A low voltage heater fault can occur because of this too.

    Hope this helps.:thumb:

    my main experience of the various diesel heaters is Eberspacher airtronics D2 / D4 models as fitted loads of them in the patient transport vehicles we built for East of England NHS, they are very economical in use but must be wired up correctly ( as in wire sizes) to prevent voltage drop. Most people say they are noisy but this can be drastically reduced with the use of an exhaust silencer, for an even quieter heater the best improvement is to put a silencer on the combustion air inlet pipe as well http://www.ebay.co.uk/itm/Eberspach...-Combustion-Air-Intake-Silencer-/290858854094

    have also used webasto in the past also very good, and Mikuni MY30's again very good,

    5kw = 0.62ltrs/hr

    2.4kw = 0.27ltrs/hr

    Eberspacher D2 = 2.2 KW = Fuel Consumption average 0.15 L/Hr
    D4 = 4.0 KW = Fuel Consumption average 0.25 L/Hr
    D5 = Heat Output: 1600 / 2700 / 4800 / 5500 Watt
    0.20 / 0.34 / 0.58 / 0.66 l/hour

    I'm a Webasto fan. Very economical heater. Very efficient. Only noisy if you stand outside in the cold??? And that's just during the start-up period when its achieving thermostat setting. Once it's done that it's silent.
