What is The Main Purpose of Ventilation?

Here at I-Sells, as the number 1 supplier of venting and ducting solutions in the UK, we endeavor to bring you the necessity of a properly ventilated home alongside all of the benefits that can be experienced. In this article we will be answering the question ‘What is the main purpose of ventilation?”

All of the solutions we offer are in an effort to disrupt the environment necessary for mould to formulate, as mould can have serious health implications as well as spread easily if left unattended.

Alongside mould control, our venting and ducting solutions also aid in the removal of condensation, retention (and in some cases addition) of heat, and the removal of stale air in your home.

History of ventilation

When we think of ventilation, we think of big tubular devices that remove & bring air into a room, but its beginnings like most things came out of necessity. It is theorised that stone age dwellings first made use of ventilation in order to keep smoke out of their living spaces.

As time developed and industrial societies became the norm, ventilation became a modern solution for hundreds of people sharing the same room for hours on end whilst still being able to breathe fresh air.

The main purpose of ventilation is to introduce outdoor air into a dwelling, building or room being evenly distributed. Its general purpose is to allow “healthy” air for breathing & diluting pollutants that may be present in the dwelling, building or area.

As a result of this fresh air, it prevents mould from growing as it disrupts the environment it needs. There are many devices and systems in recent times that can help to facilitate this function on an industrial level all the way to a local level like in your home.

Home ventilation systems

Home ventilation systems like our Drimaster range are the most effective method of curing and preventing condensation and dampness. Installed in thousands of dwellings each year, Home ventilation systems can be more cost-effective and simple to install, whilst still meeting building regulations.

Essentially the concept is to introduce fresh, filtered air into the dwelling at a continuous rate, encouraging the movement of air from inside to outside.

To achieve this, the unit is mounted in the loft space, drawing air through the filters and inputting it, at ceiling level, into the property. An integrated heater tempers airflow should the temperature in the loft space drop below a set point, ensuring ultimate comfort in the home.

The result of this airflow is a reduction in condensation and humidity, a key factor in preventing the cultivation of mould.

Benefits of a home ventilation system

  • Cure condensation dampness – reduces the humidity in the air, curing condensation dampness and preventing mould growth.
  • Improved indoor air quality and healthy living environment- Indoor pollutants from cooking and cleaning, as well as outdoor pollutants including pollen and Radon gas, are eradicated from the home
  • A Unique cost-effective solution
  • Meets Regulations – Meets Part F & L of Building Regulations as a low-energy ventilation strategy
  • Easy & simple installation – Typically installed in under one hour depending on the model you select
  • Modern, sleek circular diffuser – Provides occupant acceptability

Installing a home ventilation system

So how much does it cost to install a home ventilation system? The answer is dependent on the model you choose. It can even be done yourself.

The Drimaster units (positive input ventilation PIV) only have 1 vent. So installation is very fast. This is due to them not needing ducting as it only has 1 output vent. Someone who likes DIY can do this in a few hours.

Self-installation can be done with a handy guide by the manufacturer

If hiring someone, you will need an electrician to add power & sockets in the loft. If you already have power in loft, then the process will be straightforward.

Overall, hiring someone would be £200-£500 to install a Drimaster unit. Heat recovery options are more expensive to install simply because they need ducting and vents installed in every room or several rooms, several input and output vents. Due to it being ‘whole house’ ventilation.

However, the £200-£500 range is purely on the basis of a space that needs no additional work, or electrics. some factors may come into play when deciding the price of your installation and can be due to:

  • The complexities of the existing system
  • The energy needs of your building
  • The size of your property
  • Ease of access to pipework
  • The scope of work required in building/renovation

Ventilation without a fan

If you want the best possible prevention from the dangers of mould, ventilation systems along with having a regular ventilating routine is the most secure option you take.

However, there may be times when you don’t have access to a fan or it may not be working. Here are some steps you can take in that instance, and to add as a ventilation routine even if you do have a fan.

  • Opening a window and using an extractor fan during or after a hot bath/shower
  • Creating an airflow by opening windows on different sides of the home for around 20 minutes a day
  • Buying or making use of extractor fans within the home
  • Opening a window or using an extractor in the kitchen whilst cooking hot meals
  • (if living in a house) opening windows downstairs and upstairs, allowing the rising hot air to escape through upstairs windows, while cool, fresh air circulates in from the downstairs windows.

Track your humidity levels

Consider buying a Hygrometer. This device measures the levels of humidity in the air, which can indicate to you which rooms are creating the perfect environment for mould. This is a valuable maintenance and detection device that we offer.

Deal with it

If you find mould on your food, dispose of it and any other foods that may have been touching the moulded food, or open within the same area. If you find mould on any surfaces, clean it immediately with our anti-mould surface cleaner.

If mould reappears at a certain spot in your home, check to see if there is any leak or damage to the area that can be letting moisture in. If so, contact your landlord or trusted tradesman to fix the issue.

Browse our mould control options for the best possible solutions to dealing with mould.

Please note that these steps will not completely defend against mould if there are leakage issues in your home, but will certainly help to mitigate the growth of mould if done on a regular basis.
