Which Dehumidifier Should I purchase?
There is often confusion over which dehumidifier people need for their homes, as one the UK’s leading experts we regularly receive calls asking for advice on dehumidifiers, which dehumidifier you should select depends of factors such as size of area, what the temperature is and what is the purpose of the dehumidifier?
The two main uses for dehumidifiers in the UK are to solve condensation problem in homes and for drying washing, condensation often occurs in homes in the winter, usually forming on cold north facing walls condensation can occur when the humidity level is above 60%rH, this condensation can be a breeding ground for mildew and mould, often resulting in black mould spots forming on walls and in closets which is damaging to health. Dehumidifiers reduce the relative humidity to a level below 60% rH where condensation cannot form, in winter it is impossible to dry clothes outside and the cost of running a tumble dryer is excessive, dehumidifiers can dry clothes in an enclosed space quickly and efficiently.
There are two main types of dehumidifier you could purchase, these are refrigerant or desiccant:
Refrigerant dehumidifiers such as Meaco or the Ebac range are very effective when used in homes which are normally heated, they are quiet and energy efficient.
Desiccant dehumidifiers such as the DD8L can be used in heated homes but are also better in colder areas as they extract the same amount of water regardless of temperature, the refrigerant units performance drops the colder it gets.
Desiccant dehumidifiers are excellent for use in garages, sheds, holiday homes, boats and caravans. Desiccants are also the best choice to use for drying clothes as they produce more heat which gives a faster drying time.
The guide below is for sizing dehumidifiers in homes, depending on temperature an 8 litre desiccant dehumidifier is about equivalent to a 18 litre refrigerant machine, so for instance the DD8L could effectively manage the humidity in up to a 3 bedroom home and would be the choice if you were drying clothes.
If you have a cold area such as a conservatory or if the house is not heated at night I would tend to recommend a Meaco DD8L desiccant dehumidifier.
