Can I use a dehumidifier through the winter to stop condensation in a caravan or motorhome?
Dehumidifiers have a place where there’s a large build-up of water inside a caravan or motorhome, perhaps from condensation after you’ve been sleeping inside. It may, therefore, be useful to run such an appliance in a tourer immediately after a trip for up to 48 hours or so.
Once the interior has been brought to the same level of humidity as the outside, a dehumidifier cannot do anymore. In fact all you’ll be doing, if you leave it running, is attempting to dehumidify your garden or storage yard.
Double check against any storage advice from your caravan or motorhome manufacturer, but where none’s given consider a gentle amount of heat periodically if possible. Leave cupboard doors open. The heat will encourage air movement by convection and with the cupboard doors open airflow will be maximised, reducing cold spots, thus reducing how much moisture will condense out.
