Moist and low indoor air quality (IAQ) can cause health problems

Mould, termites and dry rot thrive in moist conditions and can be harmful for furniture, buildings and people.

Low indoor air quality or unsound indoor climate – indoor air quality in general may cause discomfort and add to the risk of disease.

Allergic reactions to unhealthy living conditions caused by mould and dry rot in our houses are numerous and increasing.

Termite infestation in Australia is increasing with high use of timber in construction and increased dampness.

The need for venting and drying out our homes and other buildings peaks during winter and autumn periods when good venting habits involve high fuel bills.

A SolarVenti solar air collector mounted on the wall or the roof is a simple, low-cost and effective solution to the discomforts arising from an unsound indoor climate.

No operating costs, high energy efficiency, consistent positive air changes and a free heating supplement may be considered an extra bonus

Child with respiratory allergic reaction

The incidence of allergy is increasing in the industrialized countries. For example it is estimated that 25% of the Danish population will suffer from allergy once in their lifetime.

Building style and health

More often than not the problems with our indoor climate and IAQ are caused by an abnormal accumulation of increased moisture in the furniture and structure of the house thereby also affecting the air we breathe every day.

We quite simply build and insulate our houses more and more to keep the expensive heat inside the building and forget that we thereby reduce the air flow and increase the air humidity.

In Australia, we allow high humidity to enter our homes when windows are left open for cross ventilation, all day or at night.

The simple solution to high air humidity has always been and still is proper airing. However, traditional venting through exterior doors, windows and air shafts involves quantify ambient air humidity levels and loss of heat, heat is energy and costs money. Even more expense and money as the energy resources of our planet become increasingly expensive to gain access to.

Economy and health

During winter and autumn periods when the need for airing and drying out peaks, the rising energy prices weigh heavily on our private budgets. But our homes are to be vented sufficiently through air shafts or by regularly opening the exterior doors and windows. Many people also want to benefit the environment by avoiding unnecessary loss of heat accompanied by carbon reduction and energy saving.

A SolarVenti on the wall or roof will typically work as a simple, low-cost and effective solution to high indoor air quality and an improved indoor climate. No matter whether your goal is to solve or improve health related problems or you just want to avoid experiencing daily discomfort in general. A SolarVenti will air your house without any loss of heat at no running costs for neither the owner nor the environment. A free supplement of heating is frequently an extra bonus.

The costs for setting up a SolarVenti will often be far less than half of the costs for a mechanical ventilation system using heat recycling. And because of the choice of material and the simple construction a SolarVenti is extremely reliable and will perform for many years without any maintenance.
