- Condensation Control: Treating Household Condensation Issues
If your property has been constructed in the last 40 years your damp problem is 90% more likely to be condensation than any other type of damp problem.
The most obvious symptom of a condensation problem is going to be water streaming down the inside of windows or walls particularly in the morning.
Condensation is one of the most common forms of dampness in residential buildings, it is caused mainly by warm, moist air formed from cooking, washing, bathing or even by just breathing condensing onto colder services in the home.
Condensation can occur at any time but is more likely to occur at night because the air temperature falls or when your heating shuts down for the night, this will be more of a problem when the outside weather gets colder.
The warm, moist air will travel to the coldest areas in your property and not just the areas causing the problem and condensate on these areas, normally this can be on the windows, corners of bedrooms and behind furniture.
Damp patches can appear on plaster walls in odd places particularly on outside walls often appearing and disappearing on a regular basis.
Even if your bathroom has no mould it is normally the main source of moisture and when you open the window the moisture naturally goes to the coldest area in the property and condensates there.
How to treat condensation
Improving heating, insulation and installing a dehumidifier will help but generally does not prove a solution as it does not treat the actual source of the problem and can be very expensive to install or run.
We recommend you following to combat condensation:
- Avoid drying clothes over radiators or in un-ventilated rooms
- Open all window trickle ventilators if installed
- Avoid the use of portable LPG gas heaters
- Vent outside tumble dryers
- Close bathroom and kitchen doors when bathing and cooking
- Leave a space between walls and furniture
A single room or multi room condensation control extraction fan (C-DMEV - D-MEV) is a energy efficient controlled way of continuously extracting moist and stale air from the wet rooms in your property to help control condensation.
Units are available with a large range of options from integral humidity sensors, CO2 sensors, heat recovery and low voltage units suitable to zone 1 wet area.
By replacing your normal bathroom extractor with a condensation control extraction fan the moist, stale air is continually extracted at a low speed from any wet room at near silent levels helping to combat condensation with a boost via a sensor or light switch achieving better ventilation and saving energy.
Our range of top quality positive ventilation units (PIV) are energy efficient units that control condensation by gently providing air to your home from a central position in the stairwell or store room.
A loft mounted positive ventilation unit draws fresh air and heat that exists in lofts, filters it and pushes it into the dwelling via a ceiling mounted diffuser simultaneously circulating existing heated air that has risen to ceiling height.
All stale air in the property is forced out through natural forms of ventilation such as doors and windows or a condensation control fan.
