Home Ventilation – The Key to healthy living & dry homes

SAM – Home Ventilation System

Installing a SAM solar powered home ventilation system will improve indoor air quality, as it removes moisture accumulated in your home. It ensures healthy living for you and your family, whilst the additional heat from the solar heating system will reduce your heating bills.

Solar Air Ventilation System Improves Indoor Air Quality

Energywise, a government-run website points out that “good ventilation is essential to maintain air quality” and remove excess moisture in your home. Having a draughty house is not the same as good ventilation. The article goes on to point out that ventilation also stops dampness in the house – which can be identified through symptoms such as condensation and mould. Ensuring healthy living through home ventilation is particularly important in modern, energy efficient homes as they are increasingly airtight and therefore lack natural ventilation.

If you live in or plan to build a modern energy efficient home – one of the last things on your mind may be the indoor air quality. However, it is a fact that many new homes have problems with condensation and indoor air quality due to lack of ventilation, causing high humidity levels and affecting the health of the occupants.

Asthma and allergy symptoms can often be exacerbated by poor ventilation but can easily be combated by the installation of SAM, as the increased ventilation and introduction of warm, dry air helps to improve indoor air quality. 

Remove Moisture to Ensure Healthy Living

The Department of Energy’s website highlights the importance of ventilation in energy efficient homes to avoid the negative health impacts of contaminants present in most homes, such as: formaldehyde, volatile organic compounds and radon. The department also highlights that moisture control is the key to mould prevention and avoiding structural damage.

The SAM solar ventilation system introduces fresh, pre-heated air into the home to remove moisture and ensure adequate home ventilation, as natural ventilation (as per the departments definition) is generally undesirable in winter due to significant heat losses.

A ventilation fan brings warm, dry air into the house from the SAM collector. The positive pressure will remove moisture by pushing it out through vents (e.g. kitchens, bathrooms) and small openings around doors and windows, which will provide effective humidity control, whilst also providing additional solar heating without any cost, contributing to your existing heating system and creating great home ventilation.

Reduce Condensation with Solar Home Ventilation

SAM is an effective alternative to dehumidifiers


A strong indication that your home has insufficient ventilation is condensation in the house, often seen on windows and skylights in the morning. Condensation will form on windows as a result of high internal moisture levels/humidity. In more serious cases condensation will stay on the windows for the entirety or for the majority of the day. The water then runs down the windows, eventually resulting in mould growth on windowsills – and possibly even on the windows themselves.

The SAM solar home ventilation system will remove moisture from the home as described above and acts effectively as a dehumidifier, although the principle is different to conventional dehumidifiers, our system achieves similar results but with the added benefits of solar heating and not having to empty the dehumidifier. 

A SAM solar home ventilation system reduces condensation and may even stop condensation in the house altogether by introducing fresh, warm and dry air whenever the sun shines (perfect home ventilation).

SAM ventilation systems can also be installed for use in drying rooms/cabinets.

A solar air ventilation system will not only ensure a healthy indoor climate and improve indoor air quality through whole home ventilation; solar house ventilation also has significant potential to assist you in your efforts to create a sustainable solar passive home.
