FAQs

What is smart control?

Ebac have developed a new way of controlling your dehumidifier, called Smart Control.

Smart Control is intelligent electronic software that replaces a normal humidistat.

It’s more effective at eliminating condensation and damp; it’s also more energy efficient and can save about half your running costs, between £30 & £50 per annum.

Smart Control is fully automatic. Once you switch your dehumidifier on and select Smart Control, you don’t need to make any adjustments to the controls; it simply runs and sleeps when it needs to.

Explore our Patented Smart Control in more detail or Watch John Elliott explain how it works

 

What is intelligent defrost?

In order to continue to operate effectively, a dehumidifier needs to defrost, just like your freezer.

A dehumidifier in defrost mode is not removing moisture, so defrosting should be minimised.

Ebac’s Patented Intelligent Defrost optimizes the defrost frequency and duration, keeping the dehumidifier running more frequently and more efficiently.

Ebac dehumidifiers are the only dehumidifiers that do this.

What’s the right size dehumidifier for me?

You may have heard that picking the right dehumidifier can depend on the size of your home. That’s not entirely accurate, for example, 2 people in a 5 bedroom house will need to remove less moisture than 2 people in a 2 bedroom house, because the bigger house has more capacity to hold the moisture.

Dehumidifiers have different extraction capacities and as a general guide the more people in the home, the more excess moisture that needs to be removed. However a unit with a bigger capacity will cost less to run than a smaller unit, providing it has a good control system.

An “oversized” unit will run less than a smaller unit to extract the same amount of moisture. They usually extract more moisture per unit of electricity and by running less frequently they last longer.

Our dehumidifiers are labelled with suitability, based on occupants, in order to help you decide which dehumidifier is right for you.

We’d recommend reading our how to choose a dehumidifier guide for more information on dehumidifier suitability.

 

How long will it take for my condensation to clear?

You should start to notice an improvement in your condensation after just 1 day, however, it could take up to a month to get excess moisture in your home under control.

We are so confident that an Ebac dehumidifier will resolve your condensation problem that we are offering a 60 day condensation cure guarantee. This is a no quibble money back guarantee. If you are not satisfied with your Ebac dehumidifier, we will refund your purchase price*.

*Guarantee only applies to dehumidifier purchases made from Ebac

What does the extraction rate mean?

The extraction rate is the amount of water that can be extracted in 24 hours.

What is the difference between the extraction rate and the water container size?

The extraction rate on a dehumidifier is the amount of water your dehumidifier will extract per day and the water container size is the amount of water your dehumidifier can hold at any one time

 

How much does a dehumidifier cost to run?

The cost of running a dehumidifier is reduced greatly with Ebac’s Patented Smart Control.

Smart control can save about half of the running cost of a typical dehumidifier, between £30 and £55 per annum.

An Ebac dehumidifier from the 2000 series will cost around 23p to remove a litre of water, a typical saving of 14p per litre of water extracted.

Where does the water come from?

The list is virtually endless; running a shower or bath, boiling a kettle, cooking a meal, doing the dishes and drying laundry all increase the level of moisture in your home.

Even something as simple as breathing, the weather and climate can add to the problem, creating condensation and damp.

 

Where do I put my dehumidifier?

For tackling problems like condensation we would recommend placing your dehumidifier in a central place, such as a hallway, keeping all doors slightly a jar. If you have certain problem areas that you would like the dehumidifier to fix then simply place it in that room/area until the problem is under control, then move the dehumidifier to a central place.

How quickly will the water container fill up?

This depends on how much excess moisture is in the air. At first you will probably find your dehumidifier collects as much as 2 containers of water per day, but after it removes the initial moisture from the air it will slow down and you will probably find yourself emptying the water container every 1-2 days.

How much moisture will I generate in a day?

Two people will generate 24 pints of moisture at home in one single day & up to two pints of this moisture cannot be absorbed by your home.

Will I need to service my dehumidifier?

The only thing you should need to replace on your dehumidifier is the filters; this should be done every 3 months.

 

Our filters come in two variants;

Bactiguard filters are designed to combat germs, bacteria and fungi.

Activated carbon filters are designed to remove unpleasant odours from your home.

 

How do I permanently drain my dehumidifier?

All Ebac dehumidifiers offer permanent drainage functionality. In order to take advantage of such functionality you can purchase a permanent drainage kit direct from Ebac – they’re simple to use and offer a simple solution.

  1. R Whittle

    We have only ever bought genuine Ebac Dehumidifiers direct from Ebac.com since the very early 1980s when we first learned about this company. They just work really well and if you do have any problems the Customer service department is the very best in every way. I wouldn’t even consider buying anything this company sells from anywhere else..

    I have had my machine for 2 weeks , and I am totally delighted . It’s operation is so smooth and quiet , even on full speed fan ; just a steady gentle hum in the background . No rhythmic vibration as I had in another machine . It cycles on and off very well , and takes out great amounts of water . Even on normal household setting in my 2 bedroom cottage it takes out at least 1 litre per day . very adjustable simple control knob like an electric cooker to create any level of humidity you want . . Plus the dark grey colour makes it unobtrusive around the house , and it is a neat compact design . Top marks Ebac
