Building a well insulated house means you will need mechanical ventilation.

ARCOS.SP installs a ventilation system with heat recovery saving you about 90% of heating and cooling costs compared to just ventilating.

How does it work ?
The unit consists of 2 fans: one to extract the stale air out of the house and the other to bring fresh air in. Both airflows pass a turning wheel equipped with a special filter material that in winter captures  the heat out of the outgoing air and transfers it to the incoming air. The material also takes care of filtering the incoming air.

In summer the system works the other way around and cools down the incoming air using the relatively cold air coming from inside the house. The system is also used to cool your house at night, when the outside temperature is warmer than the temperature inside.
