    We leave our van permanently plugged in at home. Heating is also set to low/winter setting on electric.
    What's the feelings re this? Any tips?

    My feeling is you are doing it exactly right, but only because I do exactly the same

    Will wait with you for other opinions / contradiction

    There was a comment on the TV programme 'Grand Designs' about leaving the heating on, it was to be fair, referring to a house with lots of windows.

    The view put forwarded was windows & heating bad idea, condensation.

    So I've got lots of windows in my MH... I use a dehumidifier.

    I'm a newbie and could be totally wrong (Wife claims that's normal), but so far no condensation in the MH and cushions etc. are dry, no musty smell.

    At the end of this winter I will personally know one way or the other, till then I'll keep going with the present method.

    Regards

    An interesting thread. :thumb:

    I have EHU on and flick the charger on regularly, however I was 'warned' against putting the heating on all the time as the damage from inner condensation can be quite harmful - this was by a few caravaner friends. I understand in the depths of a really cold snap it's a good idea to have some warmth around any areas likely to freeze, but I'm not too sure about a constant heat being a good idea.

    I am watching this thread carefully as I too am very interested in the outcomes/recommendations.

    Trikeman.

    I leave mine with an oil filled radiator on and two top vents slightly open and all cupboards and wardrobe doors open.
    All is cosy and dry and with the addition of water and food ready for the ferry to Spain mid Jan :thumb:

    Mine is kept inside all year so I don't worry about the heating side of it.

    I plug in a EHU every x2 weeks or so for a few hours just to keep the batteries going.

    I always kept mine on EHU at home. Unfortunately it kept the batteries full.

    Why unfortunately?

    The alternator wasn't charging due to a bad earth (I found out later). Although it was charging enough to extinguish the warning light. When I was away to a rally for two or three days - no problems (not a heavy power user). Drive back home, plug in, batteries recharged.

    After one longish drive and subsequent rally I couldn't get the van started, that's when the problem identified itself. Fortunately helpful Funsters helped me get it sorted:thumb:

    So please be aware that constant EHU charging can mask potential problems.

    Left on EHU, silver screens on, heating set to 14 degrees, all cupboards open a tad and ( at the moment) no water in the tanks.
    We have an old caravan (1987 Bailey) that we store on a farm. Haven't used it since Aug 2011 but have checked on it now and again. It is just left as it is, in a field, no damp, no smell, no leaks, in fact just as we left it.
    I suppose I could leave the heating off in the MH but it's handy if someone needs a bit of peace and quiet and to sit in when people are viewing the house ( it's for sale) if it's too wet to walk the dogs

    Hmm.. Mine has water on board (only a small travelling amount) and one of the reasons we leave it plugged in and warm is we will use it over the winter period. No condensation at all.

    Drained down, no heat, ehu plugged in and charger on.
    Our charger is designed to float and maintain all batteries. Not all are, notably some Sargent PSUs.
    If you have an old fashioned fixed output charger and leave it on, it WILL ruin your batteries!

    EHU plugged in, no heating but run a low wattage dehumidifier once a week for 24 hrs, all drained down etc, cupboards open, and on really nice days will open the roof lights for an hour or so. :thumb:

    :Wink: Use a combination of all these. Drain down. Dehumidifying crystals. Watch weather forecasts for severe frosts then use EHU and oil filled radiator. Solar panel in situ.
    But first ...........as many trips as we can. :Laughing:

    no problem.

    older vans had pretty primative chargers which may overcharge the battery but most modern ones are multi stage and can be left on indefinately

    SORRY< do you mean the MH's heating system?? we too plug into our home supply but we use an oil fired 700 watts heater to keep condensation and damp at bay and its surprising how it keeps the interior temp at 60-63F

    Mines always on, theres always water in the tank, always food in the cupboard and beer in the fridge (or the garage/locker this time of year!), the rads are left on in the winter months and the aircon in the summer, the TV's often on aswell.

    ...oh, hang on - thats 'cos we FT! :Doh:
