    Anyone any experience of the above?

    My new wagon has Alde heating and I am interested to know the difference in consumption from those that have experience.

    Come on Paul......more details.
    Do you mean an Alde wet radiator system or an underfloor installation
    You obviously mean gas consumption or possibly 12v but against what......blown air, old style convection, Bunsen burner, catalytic heater.
    Huh....just read the title so that narrows it down a bit :D

    Having just changed to a van with Alde, Anthony thinks that the difference in consumption is negligible, although it takes more gas to bring the van up to temperature from a cold start (we don't have an Alde heat exchanger). Once it's reached your desired temperature it seems really efficient consumption wise.

    I believe the Alde is a lot more efficient as far as 12v power is concerned, I would have thought gas wise heat was heat so not much to choose between the two, you will find that the N+B heats all the locker spaces underfloor and garage so your bikes will be toasty and the garage makes a good drying area for your wet gear on that basis it may use a little more gas.

    Have you got the heat exchanger.

    We’ve had both and not noticed any difference in fuel consumption, however the van feels warmer and more cosy with Alde. Plus if you’ve got the optional engine heat exchanger, you can heat the whole van and the hot water for free whilst driving - Truma can’t do that

    Echo what has been said and a big plus for the heat exchanger. Wouldn't want a van without Alde heating now, it's a much better type of heating, and doesn't use anymore gas in my opinion.

    I’d agree with that. The underfloor heating is wonderful and once up to heat does not seem to use excessive gas

    We were away over New Year (5 nights) and we had a few very cold nights when we left the Alde heating on low over night. The heating was on every day in our A class which is 7.9 Mts long - we used 14 ltrs of gas for heating, hot water and fridge over the 5 days which equates to less than £10.00 on our refillable Gaslow system.

    My RMB 760 had the Alde wet system with underfloor and radiators. It had the engine heat exchanger so during cold weather you could warm the van whilst driving. Once the van has warmed up it takes very little gas to keep it warm in a well insulated van. The Alde pump that pumps the water round is tiny compared to a conventional fan on gas heating so uses little or no 12 volt power. If the van is cold, it does take longer to warm up with the Alde system.

    Slightly off topic, but there do appear to be hidden costs associated with the Alde system.

    Every 5 years (or it may even be every 3 years) the system needs to be flushed and replaced with special non-corrosive fluid. There is a UK Alde service centre somewhere in the Midlands. Probably best to allow at least £30 per year if you have the system replenished at the Alde service centre. Failure to have the system regularly serviced can lead to very expensive bills if affected by corrosion involving ripping out the pipework and replacing. I know someone who bought secondhand where the system had not been serviced and the dealer was left with a £10k bill.

    It's just standard long life antifreeze for alloy engines and easy to change yourself, when I asked the Alde guy (at one of the shows) about servicing they said "nothing to do" but you could get the fluid tested or just change it, I changed it, you should drain a bit of hot water (fresh not heating) off now and again as the systems needs a cushion of air in the top.

    If it has a heat exchange from the engine.. Being N/B I should imagine it has..

    If you can plug in at home and put it on full a couple of hours before you set of...

    Then while mobile to your camp site venue the engine keeps an already hot system topped up and when you arrive it is only a short time to bring right up to hottest mode..

    I know what I mean... :doh:

    I think I know what you mean, the heat exchanger is on the option list for N+B vans so they don't all have it.

    Set at 30 deg on heat exchanger,from 10 pm to 5 am at 18 deg and 5 am to 10 pm at 23 deg.Perfect .Takes average 8 litres per 24 hrs in winter including the fridge and cooking.
    We use Gaslow and find many Repsol garages provide it here in Espania.

    Are you saying you can fill up Gaslow cylinders at a Repsol garage?

    Yes but I always need to borrow a Spanish adaptor to fit my French one.
