Dehumidifiers are electric appliances that reduce the humidity level in an enclosed space. A dehumidifier extracts moisture from the air to decrease humidity levels.
Too much moisture in the air can create an unhealthy environment and cause a range of issues including condensation, damp, bad odours and mould. Daily household activities such as cooking, taking a shower, using a dishwasher or washing machine, can increase humidity levels in the home. Dehumidifiers help to reduce the amount of moisture in the air.
The optimal humidity level in a domestic environment is 50-55% RH (Relative Humidity). 50% RH means that the air contains only half of the moisture it can hold. As temperatures decrease the amount of water in the air may remain constant, but the relative humidity (RH) will dramatically increase. This makes dehumidifiers very useful over winter periods.
Home is where the heart is; where we spend time with the ones we love. We all strive to make our homes a clean and healthy place to be, but you may be surprised at how much a dehumidifier can help. Rooms such as the bathroom, kitchen, garage or basement are often prone to damp and wet areas, which is perfect for mould to start growing. A dehumidifier will remove the excess moisture in the air and prevent mould build ups; delivering a healthy living space. Mould, fungus and dust mites are big triggers for asthma suffers and those with other respiratory issues. Our dehumidifiers are able to maintain a relative humidity of 50-55%, this is ideal for a healthy home.
We have a large selection of compressor dehumidifiers and desiccant dehumidifiers that will cater for both small and large homes. Check out our dehumidifiers with ionisers and antibacterial filters too! They are specially designed to keep your house mould and fungus free.
Dehumidifiers are surprisingly efficient to run. Most of our models will even automatically stop dehumidifying once the desired humidity is reached; saving on the amount of electricity used.
A dehumidifier will help to reduce bills over those winter months too. This is because dry air heats much quicker than humid air, also a desiccant dehumidifier heats the air passing through it (by approximately 10°C) helping to warm your home.
In Britain we are constantly plagued with high humidity.
Its cold outside and we have our heating blazing indoors to fight the cold; as a result humidity starts to rise. We cannot open our windows to ventilate our homes because it is far too cold and nobody wants to be heating the whole street! A dehumidifier helps to lower the humidity and keep water vapour down. This dryer air is also much easier to heat and results in lower energy consumption.
When it is not hiding away from us, the summer brings with it a lot of humidity. This humidity coupled with the heat makes for a very uncomfortable environment. A simple compressor dehumidifier will help to keep the air dry and create a more comfortable summer in your home.
A dehumidifier is an economical way to dry your clothes quickly without the cost and space needed with a tumble dryer. A dehumidifier is especially good for drying your laundry in the winter, as you can safely dry your clothes quickly, keep humidity levels down and leave your home smelling clean and fresh.
While any dehumidifier can help you with drying your clothes, most of our dehumidifiers have a special laundry function to get your clothes dry in no time.
A high humidity and damp conditions can cause bad smells and odours in the home; dangerous compounds are also created as a result of mould growth. A dehumidifier will help to regulate the air in your home and remove smells or odours.
Dampness in the home encourages insect pests to enter and breed. A dehumidifier is a lot like a quiet landlord; ensuring that the home stays at the perfect humidity and preventing any maintenance issues caused by a high humidity and damp.
Moisture in the air can cause wood to warp, shrink, expand and eventually rot. A dehumidifier will help to prevent this. A dehumidifier is perfect for use in an unattended building or during any maintenance; preventing damage caused by a high humidity or damp and helping to keep maintenance costs to a minimum.
When we take a shower, cook, wash the dishes or dry our clothes we release water vapour into our environment and this increases the overall humidity. This water vapour will either soak into our walls, floors and ceilings or become apparent as condensation. Prevent condensation and keep excess water vapour out of the air with a convenient dehumidifier.
Using a dehumidifier is one of the most effective ways to dry a home, a carpet, a wall, etc.
A dehumidifier will help to alleviate the distress that comes with a flood or a leak. You will be surprised at how effective and efficient a dehumidifier is at drying your home.
If you have suffered a flood or are dealing with a water leak, using a dehumidifier is a great way to bring your home back to normal.
There is a dehumidifier for almost everyone and every space. Whether it is for your cupboards and drawers, a small box room, a whole flat, a house, an office, a garage, or even a warehouse; we have a dehumidifier to accommodate your needs. You will be surprised once you get your dehumidifier as your family, friends, business partners or clients will want one too. Just call us on 0871 984 4416 to get help from our team.
There is no better place to find a dehumidifier than right here at APD
There are two main types of dehumidifiers on the market: compressor dehumidifiers and desiccant dehumidifiers.
A compressor dehumidifier has two cycles:
• The cold cycle freezes the water, from the air drawn in, over the refrigerant coils.
• The hot (or defrost) cycle then defrosts the ice and water is collected in the water tank.
A compressor dehumidifier will work on the principle of refrigeration. The compressor in a dehumidifier is similar to those found in domestic fridges (a rotary compressor). Compressor dehumidifiers are economical to run and efficient at temperatures above 15°C. Performance will deteriorate at temperatures below 15°C.
Water extraction is measured typically at 90% RH and 30°C for compressor dehumidifiers. A 10 litre compressor dehumidifier will extract around 3-5 litres of water at normal domestic temperatures of 18°C - 21°C and a RH of 70%.
Typical power consumption is around 200 W for a 10-12 litre compressor unit, operating at temperatures from 5°C - 35°.
During the last few years desiccant dehumidifiers (often referred to as absorption dehumidifiers or zeolite dehumidifiers) have really improved. Zeolite is a natural volcanic rock-type structure. This is formed into a honeycomb disc, which is placed inside the desiccant dehumidifier. As humid air is passed through the dehumidifier it is absorbed by the zeolite disc.
Desiccant dehumidifiers have a heating element that heats the zeolite; this discharges the absorbed water into the water tank. As there is no compressor gas, but a natural rock in the absorption disc; desiccant dehumidifiers are very ecological. The zeolite regenerates itself during the heating process.
Desiccant dehumidifiers are able to perform at temperatures close to freezing point. An 8 litre desiccant dehumidifier will extract 8 litres per day even at 5°C, provided that there is enough moisture in the air. Desiccant dehumidifiers are able to dry beyond 40% RH if required. They are ideal to use in domestic and office environments as well as storage spaces, unoccupied houses, garages and boats.
All modern dehumidifiers, whether a compressor or desiccant model, boast a range of features including things like an auto stop (when the water tank is full) or a permanent drainage option.
Top of the range dehumidifiers benefit from features like a humidistat, timer, ioniser, directional louvers, advanced air filters, auto restart and intelligent power management features.
Using a dehumidifier will help to create a healthier environment by reducing humidity, controlling mould and mildew, etc. Less humid air also heats up quicker, so a dehumidifier can help to reduce your energy bills.
* RH = Relative humidity is a measurement unit representing the amount of moisture in the air at a specific temperature compared to the maximum amount of moisture that the air can hold at that temperature and is a percentage value. Hot air can take more moisture in than cold air. The higher the RH the higher is the risk of condensation. 100% RH means that any additional moisture in the air will immediately condensate.
For a dehumidifier to work at its best it is a good idea to keep doors and windows closed while you are using the appliance. Place the dehumidifier away from walls, curtains, or any furniture, this enables it to create a good air flow. You could also vacuum first, in order to remove dust particles. You can move a dehumidifier from room to room.
It is recommended that you use it on the highest setting for a week or two. You can then place the dehumidifier in a hallway or corridor, leaving your doors open, and it will regulate humidity levels. Depending on the capacity of the unit, a dehumidifier may be able to regulate the humidity across the whole house, if not you could use one on each floor.
For permanent installation, make sure that correct hose is used at the back of the unit. This hose needs to be plumbed correctly allowing sufficient drainage. If you use a dehumidifier in a cellar or want to pump excess moisture upwards or for a long distance, we recommend using an inline pump with the machine.
