discomforts arising from an unsound indoor climate. No operating costs, and a free heating supplement may be considered an extra bonus.

Building style and health

More often than not the problems with our indoor climate are caused by an abnormal accumulation of moist 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.

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 loss of heat and heat costs money. More and more money as the energy resources of our planet becomes 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 if our tight 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.

A SolarVenti on the wall or roof will typically work as a simple, low-cost and effective solution to 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.
