Air conditioning
The included outlet hose is only 1.5 m. Can I extend it?

No, because when extended, you lose the cooling effect and the machine can shut down.

Is there a tank for water collection?

Yes, an internal tank that can be emptied via the drain plug. (The internal tank cannot be removed.)

How do I empty the collected water?

Simply unscrew the plug at the bottom. Feel free to tilt the machine slightly over a floor drain.

How do I get the most out of my AC?

By starting the machine in the morning when it is the coolest in the room, as well as pulling down blinds and keeping doors closed to the desired space that needs to be cooled.

Can I place my AC in the middle of the room?

Yes, it works well if the hose is enough.

Is there a lot of water that needs to be emptied when you run the AC a lot?

It all depends on the humidity in the room, as a rule, a lot of the moisture comes out with the exhaust air.

Does the AC draw a lot of power? Can you compare this with any ordinary household appliance?

Our AC can be compared with an air source heat pump and stove.

What is R290?

Wood’s air conditioning is equipped with environmentally friendly refrigerant called, R290 (propane). Legislation on environmentally friendly refrigerants entered into force in 2020.

Crawl space
What should I choose for my crawl space; a condensation dehumidifier or an adsorption dehumidifier?

– An adsorption dehumidifier uses a chemical material (often a type of salt material, lithium, or similar) to capture the moisture. To then dry this material, heat is used. Moisture and heat are conducted out of the space being dehumidified. A condensation dehumidifier generates a hot side and a cold side often with the help of a compressor. The moisture is condensed on the cold side to water which is then led away via a hose to a sewer or into the ground. (Note that the amounts of water are very small and the soil absorbs the moisture without any problem. It is important to keep in mind, however, that you must seal all valves so that no moisture enters from the outside). In the last 8 years, Wood’s has sold more than 17,000 dehumidifiers for use in crawl spaces and is used by leading house manufacturers as standard equipment for use in crawl spaces in all of their houses. (Wood’s dehumidifiers are made for Nordic conditions in Sweden and work very well even in cold conditions, down to +2 degrees).

Dehumidification
I want to use my Wood’s dehumidifier in a storage room that is cold in the winter. Do I need a heating fan?

– The temperature must not fall below + 5° C because the defrost does not work below this temperature. Therefore, it can be smart to use a heating fan with so-called frost protection that always ensures that the temperature does not fall below + 5° C. Our MRD14, MRD20, MDK11, MDK21 / 26 models and the SW series have a function that switches off the machine when the temperature drops below + 5° C. The machine starts up again when the temperature rises above + 5° C.

Is it possible to connect a hose to the Wood’s dehumidifiers for continuous dehumidification without emptying the container, if so, does it work for all models?

– It is possible to connect a hose to drain the condensed water to all models. It comes with an adapter that is screwed onto the water trough on the SW series machines and DSC50FM. This is especially suitable because you then do not have to empty the tank and the machine can instead maintain the right moisture level at all times. Most models use a standard ½-inch garden hose; on the smaller models a 10mm hose is used.

Can a Wood’s dehumidifier manage to dehumidify the entire basement level while drying laundry?

Did you know that a dehumidifier is like a small heat pump? Let us explain: Wood’s dehumidifiers consume between 0.240-0.803 kW in maximum mode – when it is very hot and very humid (30 degrees Celsius heat and 90% relative humidity). The lower the temperature and humidity, the calmer the machine runs. This is significantly smaller than drying cabinets and dryers, which usually consume 2 kW. Every water molecule in the air carries energy, and when water is removed from the air, heat is released, more specifically 0.63 kWh / litre of water. This means that all the energy that the machine consumes comes back as heat (at the same time as heat energy is released when the water is condensed), which the elements do not have to contribute. Very clever! In addition, it is easier to heat dry air than humid, so you save heating costs that way too. Even when using the dehumidifier in a crawl space, you can feel that the floors on the ground floor get a little warmer. The stronger the dehumidifier, the more energy efficient it becomes (gets more litres of water per kWh used).

To summarize, the answer is YES! A dehumidifier from Wood’s can dehumidify the entire basement while drying the laundry.

What should you keep in mind when choosing a dehumidifier to dry the laundry?

What distinguishes a dehumidifier with a higher power from a weaker one is that it dries the laundry much faster and more energy-efficient. How long the drying time will ultimately depend on several variables such as washing volume, spin speed on the washing machine, basement ventilation, etc. With SW42FW and DS40FS, the drying time on a washing machine is usually 2-3 hours. With a weaker dehumidifier, it dries overnight. Not only does it dry laundry, but Wood’s dehumidifiers can, thanks to its superior capacity, also dry wood in a boiler room, a wet golf bag, and children’s rainwear while keeping mould and musty basement odours away.

What are the advantages of condensation dehumidifiers compared to adsorption dehumidifiers?

There is only one advantage to an adsorption dehumidifier and that is that it also works when it is below + 5 ° C. On the other hand, the air is so thin then that it hardly contains any moisture (in grams / m³ seen), in addition, mould does not grow below + 7 ° C. The advantages of Wood’s condensation dehumidifiers are many:

  • They have significantly lower power (150-400W) against adsorption dehumidifiers (600-1200W).
  • They are easy to install (just connect to a grounded outlet) and you avoid the cumbersome piping etc that are required for many adsorption dehumidifiers.
  • They do not require service (only clean the filter at regular intervals).
  • They are relatively inexpensive to buy.

 

The only thing that needs to be bought is a garden hose (½ inch PVC hose). Adsorption dehumidifiers can cost 10x the price of a condensation dehumidifier, including installation.

What moisture level should the machine be set to?

– We recommend that you keep 50% relative humidity in the entire space that the machine is to dehumidify. This is to avoid the growth of mould, (which grows above about 70% R.H.) and bacteria that grow above about 55% R.H. (Read more about mould under the tab mould, etc.).

What does relative humidity mean?

– The humidity in the air depends on the temperature in the air. The higher the temperature, the more moisture the air can carry. This ratio is exponential so, for example, 5 ° C and 80% R.H. contains about 3 grams of moisture per m³ of air while 15 ° C and 80% R.H. contains 8 grams of moisture per m³ of air.

What should I choose for my crawl space; a condensation dehumidifier or an adsorption dehumidifier?

– An adsorption dehumidifier uses a chemical material (often a type of salt material, lithium, or similar) to capture the moisture. To then dry this material, heat is used. Moisture and heat are conducted out of the space being dehumidified. A condensation dehumidifier generates a hot side and a cold side often with the help of a compressor.

(Wood’s dehumidifiers are made for Nordic conditions in Sweden and work very well even in cold conditions, down to +2 degrees).

Tests and comparisons are often made at very high temperatures and/or humidity levels. How to compare different machines with each other and at what values?

–Most dehumidifiers available on the market are manufactured and adapted for use in countries where temperature and humidity levels are very high. The defrost function etc., therefore, do not make them suitable for use in areas that are colder and even slightly drier. We recommend that you set the dehumidifier to 50% R.H. because you want to avoid bacteria and mould. Normal temperatures in basements and other spaces in the Nordic countries are 15 – 20 ° C. In normal use, we recommend setting the dehumidifier to 50% R.H.

As soon as the moisture level exceeds 50% R.F. then the machine starts, which means in practice that a large part of the machine’s use takes place between about 55-65% R.F.

It is under these conditions that capacity and not least energy efficiency are most interesting. (Tests can also be done at lower temperatures, for example, in crawl spaces). In some tests and brochures, it can be seen that values of 90% R.H. and 30 ° C occur. This is completely uninteresting because tests at values of 90% R.H. are completely fictitious when moisture is injected into a space for 24 hours. Then even a dehumidifier with poorer airflow and capacity can get good values.

Can you buy a dehumidifier with too much capacity?

– It is always better to buy a machine with a large capacity that works properly during the periods of the year when it is more humid (late summer and autumn). Many people also use their dehumidifiers in the basement to dry laundry while drying out of the basement. This is perfectly fine, but you should then keep in mind that you add moisture to the space (through the laundry) and you should then make sure to use a machine with good capacity (eg SW series: SW22, SW38, SW42, and SW59).

Why should I buy a dehumidifier instead of a heating fan?

– A Wood’s dehumidifier is made for basements and cold spaces and condenses in an energy-efficient way to remove the moisture from the air. Each litre of moisture in the air has about 800 watts of heat energy. As the moisture condenses on the dehumidifier’s cooling coil, this energy is regained as pure “gain” in the form of heat. The energy effect in the space is consequently the compressor’s effect + the “energy gain” (approximately 800 watts per litre per water that is dehumidified).

There are Wood’s dehumidifiers with smaller and larger sized tanks. Which one should I choose?

– A large tank volume is always preferable because a smaller tank can be quickly filled during a day if it is high season and humid in the room.

Humidifier
When should I use my humidifier?

Especially in winter, when the air in our homes and our workspaces can be extra dry. A humidifier simply makes the air more humid. A person who feels dry mucous membranes has asthma, allergies, or a respiratory infection can use a humidifier. Many also experience that their mucous membranes are not as dry when they add moisture to the indoor air during the winter. If the humidity is below 40-50% RH for a long period.

When should I use my humidifier?

When the relative humidity is below 50% RH, it is recommended to use a humidifier. Normally the relative humidity is 15-30% during late autumn and winter, so it is mainly during autumn and winter that a humidifier should be used.

Do I need a humidifier?

In the winter, the air in our homes, and our workplace, becomes extra dry. During this season, when the outdoor air is cold, the indoor air cannot carry as much moisture. When the air is ventilated, and heated to the indoor temperature we want, the relative humidity becomes even lower. The dry air can cause itchy, dry eyes, itchy hands which can sometimes cause stinging dry cracks or cracked cuticles. But also dry sinuses and mucous membranes, which for some can lead to discomfort in the nose and throat that makes us more susceptible to viruses and bacteria. A humidifier raises the humidity in the room and reduces the inconvenience caused by dry air.

What is the difference between an ultrasonic and a hybrid humidifier?

An ultrasonic humidifier has a diaphragm that breaks down the water molecules so that visible steam is blown out with the fan. Then the fog is usually at room temperature, as neither cold nor heat is added. A hybrid is usually a combination of hot and cold steam. It has a heating element in which heats the water so that the steam that comes out feels more tropical and warm.

Why do you have filters for the humidifiers?

The filter binds the lime in the water so that lime does not follow out and settles as white dust on surrounding surfaces.

What are the benefits of the humidifier Vienna HSW100?

Wood’s Vienna HSW100 is a unit that produces invisible cold water vapour to increase the moisture level in the air (humidity). The device has a water level sensor to make sure you know when there is enough water for the device to work. The dry air passes through the wet filter and moisture spreads in the room. Minerals and other contaminants will get stuck in the filter. Clean and invisible steam is released throughout the room employing a powerful but silent fan. The cold fog spreads easily in the air. Wood’s humidifiers have incredibly low energy consumption in combination with a very low noise level. The Vienna HSW100 can be used all days of the year, all year round and will still not consume more than 20 kWh throughout the year. The filter is an antibacterial filter made of honeycomb paper that is both environmentally friendly and healthy.

Where should I place my humidifier?

A humidifier can be placed high on a shelf or chest of drawers, 1-2 meters up from the floor. When it is a little higher up, it is easier for the steam when it falls towards catching the moisture emitted by the humidifier. It is also easier to direct the flow converter when the machine is placed a little higher up from the floor.

 

Should I turn on my humidifier during the night?

Absolutely! The humidifiers from Wood’s are very quiet and energy efficient and with the moving nozzle, you can direct the steam where you want.

Can I turn on my humidifier all year round?

It is more common for a humidifier to be used for offices and public environments all year round. But dry air can also occur in private homes or apartments, so check the humidity with a hygrometer. If the humidity is low, then a humidifier can help create the right level of humidity in your indoor air.

Ozone generator
What are ozone generators used for?

Ozone units are used for odour removal in restaurants, kitchens, garbage rooms, and hygiene areas, as well as for smoke/odour remediation of cars, caravans, summer cottages, hotel rooms, and homes.

What should I think about before an ozone treatment?

Clean the room properly, vacuum and wipe all surfaces, and/or repair/remove the problem that caused the odour. Remove pets and plants. Remove valuable high-tech equipment, e.g. laptops and valuable oil paintings. Make sure no people are present in the room.

How do I ozone a space?

Place the ozone generator in the center of the room (preferably on a slightly raised surface, such as a table). Switch on the ozone generator and set the timer to the desired time (models with one timer).

What should I think about when my ozone treatment is finished?

Turn off the ozone generator and open the windows. Let the remaining ozone come out (smells like chlorine). Check the room. Repeat the procedure if the unwanted odours persist. All affected rooms must be treated separately.
