What Is the Best Dehumidifier?

Humidity can happen in the cold countries but also warm places

In some countries warmer weather brings humidity problems such as in many States of America and in those countries a dehumidifier can be used instead of a central air conditioning system to lower the humidity of the air and make it feel cooler and is sometimes called.. a poor man’s air conditioner.  Humid air in the summer can feel sticky and unpleasant and makes us sweat more.

dampness condensation and mould

Basements are relatively cool areas of the home and they are mostly built into the ground where again it is relatively damp or even wet.  The moisture from the home will tend to condense in the coldest part leading to harmful effects such as condensation, dampness and mould.  In the worst case this can even be wet rot.  A dehumidifier can help prevent damage to these areas.  Condensation is a symptom of the whole house not just one room.  The room affected just happens to be cooler than the other places in the house.

Condensation, mould spots, loft condensation, mouldy wardrobes, utility areas or bathrooms are all symptoms of excess humidity problems often originating from inside the home.  

The need for home dehumidifiers in Europe generally follows the pattern of winter rainfall patterns in the regions, proximity to lakes, rivers & the sea.  All of which increase the levels of humidity and there is predominantly a winter need.  Excess humidity in the home condenses on the coldest surfaces whether on windows, bathrooms, in wardrobes with external walls or even it can migrate through the ceiling to the loft.   Condensation in the loft is not a problem of the loft its a problem of the whole home.

The map shows why for instance the West of England generally suffers more from humidity problems & why not surprisingly more dehumidifiers are sold to this region.  Weather is not the only issue in Europe contributing to humidity, its generally our modern living.

In certain conditions, usually in cold climates or winters, the space under house or crawl space can have excess moisture.  This does not have an immediate noticeable affect but can damage especially any wooden construction unless dehumidified or protected with expensive protective coatings.

Rising damp is something very different and is often due to the damp membrane home & house construction issues.

Insulation,  double or triple glazing makes the problem worse

Double glazing & insulation keeps the moisture generated in the home of course inside.  It is a modern goal to conserve energy and keep the heat in which also traps in moisture.  A draughty home will not have a problem with condensation.  The more people cook, bathe, wash or simply breathe in a modern insulated home to keep the heat in, the more the potential problem gets worse.

What Are The Signs Of Excess Humidity in Colder Climates?

The first sign of excess humidity in the home is simply condensation on the windows.  The next most common sign is mould spots & general dampness.

where problems are caused in the home

Another key factor apart from the weather & insulation is the number of people in the household. The more people, the more water due to bathing etc, A larger house will have less problem with condensation than a larger house with the same number of people.

Conservatories & Single Story Houses Need Larger Units

In a two story buildings air is circulating up and down the stair well circulating and moving the air around the home.  This means there is less need to physically move air to a dehumidifier with a fan.  Air needs to move to and from the dehumidifier.  In a single story building you need to draw the air to a single point from potentially further away from the dehumidifier.

Solving a problem in a room or cupboard is usually pointless,  The issue tends to be in the whole home.  Solving it in one place means it may still appear somewhere else

A conservatory is a large area to keep dry.  Possibly a dehumidifier may be needed just for this space & a cold surface.  Same is true for a basement, crawl space or loft.

Desiccant Verses, Compressor & Rotary Dehumidifiers

A reciprocating compressor is the oldest technology.  Its usually the same as you will see at the back of your refrigerator or freezer.  A rotary compressor is what you find in an air conditioning unit.  Rotary compressors are generally quieter, more energy efficient and allow the uni to be more compact.  Ecor Pro only uses & sells rotary compressor units.

A desiccant dehumidifier uses a special material that absorbs moisture but gives out moisture when heated. Therefore, there is a heater inside. in our blog

If the room a dehumidifier is being used will be below 19°C its better to use a desiccant.  Above 19° its sometimes better to use a compressor unit.  Desiccant units do consume more power but the Watts per liter of water extracted can be similar to a compressor unit which will be a subject of a later blog.

Ecor Pro prefers desiccant technology   The reason being that in most cases extraction will be higher with desiccant dehumidifiers.  The heating & higher running cost of a desiccant may be offset against home heating bills.

The Ecor Pro dehumidifiers use “SEA” technology that can save 40% of the energy anyway by smart operation controller technology matching usage to your home environment, number of people and weather conditions.  A true innovation.

Often desiccant units are used in homes with poor heating to maintain a habitable temperature.

 

Where to Put a Home Dehumidifier?

where to locate your dehumidifierThe ideal location of a home dehumidifier is a in a hallway or ideally landing with all doors slightly open to allow circulation of air. In the first weeks of using a domestic dehumidifier should be located  in the room that has the most issues with excess humidity. When the amount of extracted water from that room falls significantly and the room feels dry, move the dehumidifier to a central location in the home either a hallway or landing.  Don’t turn it off.  simply regulate the setting that maintains the moisture balance for the home over the winter period.  You will find you can turn the setting down.

Please not that a humidistat that is used to regulate the dehumidifiers in general is counter intuitive. A high setting is a setting to high humidity which people want to regulate.  So high is more damp & Low is less damp.  Some will have percentages on the humidistat and humans are comfortable between 45 & 65% humidity levels.  65% being the most humid.

Please not that a domestic humidistat can have a 15% tolerance factor built in at manufacturing stage (Ecor Pro’s 5%) meaning they are not perfectly accurate.  Also, our controllers will allow for minor fluctuations so the Ecor Pro dehumidifiers are not turning off & on in quick cycle saving wear and tear on the Ecor Pro units and giving longer life to the product.

What is a Dehumidifier Alternative?

Simply keep a window open!  That will stop condensation or install air bricks or an extraction fan and turn up your heating.  Sounds simple but they will work.  Old houses that were draft ridden had few problems with condensation.

But we want to keep the heat in

PIV systems or air bricks

You could also buy a system of pumping fresh air from outside into a home (Positive Pressure Ventilation Systems).  These alternatives will all work but of course they are ultimately expensive.  Heating the home is very expensive.  Sealing the home with better windows & doors, loft insulation is also very expensive so why put a system in that counters all that energy saving expense?  Not to mention damages the environment.

De humidification works best because it allows you to keep the heat in and keep the drafts out.  Ultimately, a dehumidification system is far more cost effective than other alternative solutions.

Downside of Home Dehumidifiers?

Generally, they cost money to purchase & of course run.  The compressor home dehumidifiers will use a little more electricity that your home refrigerator & the desiccants around the same as a large plasma TV.

The other problem is they have a footprint so take up living space.

No matter what a dehumidifier will make a noise.  We are very accurate on our sound level tests and our units tend to be the quietest when placed next to competition products so you can make of that what you will.

Our construction of solid plastic means sound is reduced more than other models but we feel that is important.  The fan in an Ecor Pro dehumidifier is always true unlike other models again a sign of sound reduction and quality in manufacture.  If you see the fan of any product wobble side to side through the grills its a sign of a poorly constructed unit.

Often customers will buy a unit that is too small & not suitable for their home so will not solve the problem.  In some cases, 2 or even 3 dehumidifiers are used to keep the problem under control in places around the home.

Lack of Fresh Air

However, the biggest problem with a home dehumidifier is lack of fresh air.  Fresh air is essential to keep the family healthy.  If we close the windows, prevent the drafts & create a highly energy efficient home we can still have a sick home.

Ideally we want to keep the home dry, keep the heat in but allow fresh air in also
