Utilizing a dehumidifier in a motorhome or camper
Look on any discussion board or group, and also you’ll see a dialogue concerning the practicalities of utilizing a dehumidifier in a camper, motorhome, RV or boat to take away moisture from the air.
Some folks swear by them, others say they’re a waste of cash. So which is it? If you happen to’re going to go away your motorhome unused for a time frame (normally over winter), must you be utilizing a dehumidifier?
Why Moisture is a Downside in Motorhomes
Motorhomes are AWFUL for moisture construct up. The confined area and vary of makes use of (kitchens, bogs, residing areas, and sleeping) create the right setting for moisture to build up.
Simply being in a single for a day causes one thing like a litre of moisture to enter the air. Add to that moist coats, pets, restricted air flow and many sizzling drinks, and you’ll see the way it rapidly builds up- particularly in Autumn and Winter.
Left unchecked, all this moisture can result in a number of points that have an effect on each your consolation and the longevity of your motorhome, together with:
- Condensation Buildup: Persistent condensation can result in water pooling on surfaces like window ledges, which can seep into the construction of the motorhome (particularly unhealthy when you’ve got any wooden within the base construction.)
- Mould and Mildew: Excessive humidity ranges create an excellent breeding floor for mould and mildew, which cannot solely harm your motorhome’s inside but in addition pose well being dangers, notably for these with allergic reactions or respiratory situations.
- Damp Smells: A musty odour is commonly one of many first indicators of moisture issues, attributable to damp materials, carpets, or hidden mould development.
- Harm to Fixtures and Fittings: Over time, moisture can warp picket fittings, corrode steel fixtures, and harm upholstery or insulation.
- Everlasting Harm: Extra moisture can considerably cut back the lifespan of your van’s inside and result in expensive repairs. For full-time vanlifers or these touring in cooler seasons, addressing moisture is essential to make sure a dry, wholesome residing setting.
The way to monitor the humidity ranges in your camper
If you’re not sure of the humidity degree in your van and don’t have an inbuilt monitoring system, you might add one in all these humidity displays to your motorhome or campervan:
If you happen to’re leaving the van in storage for winter and aren’t there on a regular basis, you’ll in all probability favor one thing just like the final one, which has an app and alerts for monitoring the automobile if you’re not there.
The Issues with Dehumidifiers
So, we all know we don’t need quite a lot of moisture within the automobile. Absolutely a dehumidifier is the right solution- sure?
Effectively… perhaps. Nevertheless it’s not that straight ahead.
Dehumidifiers work by eradicating moisture (humidity) from the air, stopping that moist air resulting in issues like mould and condensation in your motorhome.
They work to take away any extra moisture till it’s in an optimum vary (normally 40-60% humidity).
The difficulty is, most motorhomes and campers aren’t absolutely sealed. They’ve (intentionally) air holes to permit gasoline to flee. There are additionally typically tiny gaps round door frames and window frames (intentionally or attributable to many miles of driving over bumpy roads!)
All of which means- the dehumidifier isn’t glad. As extra (damp) air enters the van, it retains working and dealing… and dealing.
This will result in issues reminiscent of giant electrical drain, burnout and, in essentially the most excessive circumstances, hearth.
However that doesn’t imply they’re not worthwhile. The truth is, there are some I extremely advocate. Learn on…
Fulltime Vanlife vs Storage
Many individuals who reside full-time of their motorhome or camper haven’t any want of a powered dehumidifer, as they’re continually within the automobile to present air flow and heating. For that cause, in case you’re in your van so much all year long, I like to recommend one thing like these Moisture Absorbers – a good friend of mine who lives full-time in her van swears by these.
HOWEVER… in case you’re winterising your motorhome (placing it away for the winter), you’ll want to do one in all these three issues:
Dehumidifiers Vs Heaters Vs Air flow
As talked about above, there are a few different methods to cope with the winter damp and chilly. Heating and Air flow.
A dehumidifier actively removes moisture from the air, tackling condensation and decreasing the chance of dampness and mildew. Nevertheless, it doesn’t deal with the foundation explanation for moisture. It would heat the air barely, however not sufficient for chilly air to change into heat.
Heating raises the temperature contained in the motorhome, which might help cut back condensation by warming chilly surfaces, however by itself, it doesn’t take away humidity from the air.
Air flow permits moist air to flee and recent air to flow into, stopping humidity from build up within the first place. Whereas air flow is important for decreasing general moisture ranges, it may be much less efficient in chilly or wet climate when holding home windows or vents open isn’t sensible.
The best choice is to mix these strategies. which is simply one of many causes it’s best to verify in your automobile often and keep it if you’re not utilizing it.
How Do Motorhome Dehumidifiers Work?
For the aim of motorhome, caravans and campers – there are two forms of dehumidifiers that we’ll have a look at:
- Compressor Dehumidifiers
- Desiccant Dehumidifiers (I’ve additionally added in moveable dehumidifiers, as they work the identical manner for our functions)
Compressor Dehumidifiers
Compressor or Refrigerant dehumidifiers work by drawing in moist air utilizing a fan. This air then comes into contact with cooled coils, the water within the air condenses and drops down right into a water reservoir, whereas the (now dry) air passes by the nice and cozy coils and heats again up, earlier than being launched again into the encompassing setting.
As a result of these use cooling and heating strategies, these dehumidifiers normally require mains energy to work. Additionally they require you to empty the water tank often or they cease working.
I’ve used a compressor dehumidifer for years in my lavatory and it’s good (particularly for bogs with out home windows). It’s additionally nice for motorhomes that are saved someplace with a mains energy supply and could be monitored (like on a driveway)
- How They Work: These use a compressor and refrigerant to chill a coil, inflicting moisture within the air to condense.
- Greatest For: Heat or reasonably cool environments.
- Benefits: Vitality-efficient and highly effective in greater temperatures.
- Drawbacks: Much less efficient in colder situations, as they depend on heat air to operate effectively. Want mains energy. Must be emptied often. Shouldn’t be left on for hours unattended.
Desiccant Dehumidifiers & Transportable Dehumidifiers
Desiccant fashions work utilizing water-absorbing materials to gather moisture. They normally encompass absorbent supplies like gels, silica beads, or salts. Humid air is drawn over the fabric and because the air cools moisture is collected.
As soon as the absorbent materials is full you’ll need to both change or recharge the pouches or change your entire dehumidifier gadget.
As a result of these dehumidifiers use a fabric already in place, they typically don’t want any energy supply in any respect. These are good for motorhomes or caravans that are in storage over winter. The powered variations are higher in bigger areas, however are sometimes noisy.
- How They Work: These use a chemical desiccant to soak up moisture from the air.
- Greatest For: Chilly climates, off-grid or winter motorhoming, small areas like wardrobes
- Benefits: Operates effectively in low temperatures, quieter than compressors. Most don’t require energy
- Drawbacks: Powered variations use extra vitality in comparison with compressor fashions. Want altering often to be efficient. Not good for giant areas.
Which Dehumidifier to decide on?
So, which sort is greatest in case you’re not utilizing your automobile all through winter? Listed here are some questions that will help you select:
- Do you retailer your automobile at dwelling or very close to by so you possibly can verify it day by day/ often?
- Do you will have 230v energy whereas your van is in storage or on the driveway?
- Will you have the ability to get to the van to empty a full container?
If the solutions to those are all sure, then I like to recommend a compressor dehumidifier alternated with a heater like an oil-filled radiator. Depart the heater on, and a few times per week, run the dehumidifier.
If the solutions to 1 or all aren’t any, go for a number of non-powered dessicant dehumidifiers. Ideally, go to the automobile not less than as soon as per week to place the heating on, air it out and forestall giant ranges of moisture build up. (The humidity monitor can actually assist together with your peace of thoughts.)
Ultimate Ideas
A dehumidifier could be a useful device in managing moisture in your camper. Nevertheless, it’s not a standalone answer. Combining a dehumidifier with correct air flow and heating ensures the very best outcomes for holding moisture below management.
If you happen to’re nonetheless not sure, begin by monitoring your motorhome’s humidity ranges with a hygrometer and assessing the moisture points you face. With a little bit trial and error, you’ll discover the right steadiness to maintain your motorhome dry and cosy on each journey.
