How to Ventilate Your House?
28 September 2021
Every single property in Scotland, England, and Wales sits in the shadow of condensation – a by-product of everyday life that if left untreated and ignored can lead to some pretty serious damp issues.
Now, in nearly every single situation in which condensation is involved, the inhabitants are going to be told that one way to control condensation is via ventilation. This is great advice and can have a major impact on the amount of condensation that is actually present, but what does ventilation actually entail?
So, we hope here to run through the steps you should be taking to open up your property and promote better ventilation within, giving you a much better chance of keeping condensation at bay.
Why Do I Need to Ventilate?
Ventilation might not be at the forefront of your priorities when it comes to your household management. The simple fact though is that without adequate ventilation you are opening your property up to the possibility of damp.
It happens like this. Condensation builds up as a result of your everyday activities and life; washing, cooking, cleaning, and any other activity you can think of that contributes moisture to the air. Yes, the amount of moisture released will vary depending on what’s being done, but the fact is, it’s there.
So, without proper ventilation that condensation is going to have nowhere to go. That means it’s going to settle on your properties walls, and other surfaces. Which, in areas like bathrooms or kitchens where dense condensation is more likely to occur, you might find that your property starts to develop damp problems.
Damp leads to black mould issues, to your properties fittings and decorations being damaged, to unsightly blemishes, and even affecting your health if left unchecked. All of this is avoidable, if you just learn to ventilate your property correctly and reduce the level of condensation in your home.
So, what are the best ways and methods of ventilating your property?
How to Ventilate Your House
When you are looking to ventilate your house, you want to keep in mind your end goals. Remember, humidity is always going to be produced, so focus on measures that either reduce condensation massively, or aim to remove the humid air from your property.
How can you do that? What follows are a few different methods through which you can actively reduce the amount of condensation coming to rest within your home.
Let’s start by talking about the different measures you can take in your everyday life that can assist in ventilating your home.
First off, consider your bathroom habits. The bathroom is one of the rooms in your home that is most prone to damp being borne out of condensation, so consider your routine in here very carefully. Could you reduce the temperature or length of your shower?
How about your taps, are you turning them off when they aren’t being used? Or, could you switch from washing your face with hot water to cold water? If you take a bath, could you fill it partly with cold water first, then hot, to avoid it steaming as it fills?
A big step towards controlling the condensation in your home is the temperature that it’s kept at. If you have a home that goes through rapid shifts in temperature, it is much more likely that you are going to have condensation appearing on your walls.
The reason is pretty simple: If you have a room full of hot humid air after a shower on a cold day for example, and that air is coming into contact with cool walls, the moisture making up the humid air is going to transfer to the cool walls and become a liquid state thanks to the lower temperature on the walls.
So, by keeping your home at a consistent temperature, you might be able to control the amount of condensation making its way onto your walls and other surfaces.
All of these little actions add up. This translates to other rooms too – if when your cooking, could you put lids on your pans? Or, instead of drying clothes on your radiator, could they be dried outside, or in a room with more rigid and capable condensation control measures.
All of these small actions add up, and examining your everyday life might go a long way in reducing the overall amount of condensation staying in your home.
Single Room Ventilation
There are a number of approaches you can take when it comes to ventilation, one of which being a single room approach. If you believe that your home is adequately equipped when it comes to ventilation, but one room is giving you issues, then you can tackle them individually – or find solutions bespoke to the room itself.
So, what options are available to ventilate a single room? The answer most people arrive on first is a dehumidifier.
Whilst dehumidifiers are handy in smaller rooms, they can be less effective in areas that are more spacious – so make sure you keep this in mind before you make a final purchase. If you do want a more active solution to help remove humidity and moist air from a specific room, there is a great option available: an extractor fan.
It might well be an obvious solution, but extractor fans are brilliant at removing potentially damaging humid air from a room either at the owners control, or automatically. This is because some extractor fans are made with built in sensors to only turn on when a certain level of humidity is reached, whilst others can be turned on with a light switch, or with an independent power source built right into the extractor fan.
These fans create pressure that collects and expels the humid air out of your property, either directly through a wall, or through vents that can be installed in a loft or between floors, which in turn lead outside.
Consider contacting a professional to learn more about installation options, but extractor fans are best utilised in rooms like kitchens (above cookers) or in bathrooms (near showers) where a lot of humid air is likely to be created.
Opening Windows and Doors
You can also look into methods of creating natural drafts and airways through your rooms. Opening windows and doors is always a good start, but look into the possibility of having a trickle vent installed.
Trickle vents are vents that sit in your window that can allow air to pass through even when your windows are closed. That means even when it’s raining you can have an air current running through your room, allowing humid air to escape and for fresh air to enter.
Whole House Ventilation Options
When it comes to ventilating your whole home, you are going to need to look into mechanically based options that can keep a steady airflow that promotes the intake of fresh air, and the expulsion of humid air at the same time.
A perfect option here then is a positive input pressure system.
A positive pressure system is a device installed in your home (usually in your loft or a high point within your home) that creates a consistent flow throughout your house. The positive pressure system draws in cool air from the exterior of your home, and then channels it around your property through vents into the different rooms of your house.
This process has two primary resulting effects. The first is that fresh air is being pumped into every room that the positive pressure system feeds into, and the second is that this influx of fresh air pushes humid and dense air out of your property.
So, a low level of pressure is created in your home that works to constantly keep your home free of dense, humid air.
Positive pressure systems are a constant solution as well, working around the clock to ensure that your home remains well ventilated at all hours. These are great systems for rooms that might not have other forms of ventilation available to them as well, like basements and cellars, or interior rooms, as they will have newfound access to a fresh air supply that might otherwise be unavailable to them.
