    Having invested in a dehumidifier I would be interested to hear other user's views on most efficient usage. Is it better to use continuously, daily, timed, etc.? Thanks in anticipation.

    Keep it on 24/7

    Most have a setting which works a bit like a thermostat but to be honest we have ours on high and it never switches off except to tell you the bucket is full

    I have to ask, why do you need one ?

    Nature abhors imbalance, unless your van is hermitically sealed it's a total waste of energy, the dryer only pulls in more moisture from outside.. the air in a van will always be at the same humidity as the ambient outside, it's doing absolutely no good whatsoever, unless of course your van has a leak in which case it would be better to rectify.

    I assumed he was talking about one in his house :Eeek:

    Agree with you if its for the van......far to much ventilation/holes in the vans to make them any use at all.

    I think maybe you have your answer now, useless in the motorhome unless you have a leak. But then perhaps you intend using it in the house. Dry heat, i.e. not from gas is the best way to keep the damp outeven a low wattage greenhouse heater will do the trick.

    why's that then Jim......is the house hermetically sealed.

    just the same as the van, it will only pull in more moist air from outside.

    Hi John

    No and correct, but if your living in a house or van you are producing a lot of moisture, cooking, showering, washing etc .. not forgetting what we breathe out, which can be removed by a dehumidifier, but again, not lower than outside humidity..

    Having owned a boat for years all I can say it without one I had to remove all the cushions every winter to avoid the dreaded black mildew spots but with one even set low I could leave the soft furnishings in and no spots ever.
    I agree though that having it work flat out is a waste of energy. I tend to use mine for a few days after I have been out on the road just to get any excess moisture out then I leave off .

    Stick a few Funsters in.

    The hot air will keep everything in good shape

    Hi

    I can understand why a boat in storage would benefit, different set of conditions, with a virtually sealed space and no air circulating moisture would be trapped and as you say cause mildew.. I don't imagine there are many drop out vents in a boat .. :Laughing:

    Definitely not in the hull …. mind you I’ve seen a few in my time usually accompanied by extreme dampness and of course some ripe swearing :Rofl1:

    Back to the subject in hand, :BigGrin:

    About a couple of hours a day @ night just to lower the RH. I take on board comments about waste of energy, but the action of dehumidifier seems to "sweeten" the air and make the interior not smell "damp" (If you can smell such a thing).

    We know that moist air will still get into a van, but what the point of a dehumidifier is, is to stop the soft furnishings absorbing excess moisture. Which they will do and eventually reach the point where the moisture and stagnant air could produce mildew and mould.

    A dehumidifier will lower the humidity in a van, I have compared it with an unused, closed bedroom and the humidity in the bedroom is consistently higher than the van with a dehumidifier.

    Another benefit is that as the dehumidifier uses a fan to draw the moist air in it also whooshes the air around the van to stop any stagnation occurring.

    I have mine set at a medium level which roughly equates to 50% humidity on a wet day. At this setting in switches itself on and off as required and I get about 1.5 litres a day out of it.
