Heat recovery unit fitted with very effective heat exchanger which is using heat from air inside to increase temperature of air coming from outside. Or opposite if air outside is warmer than inside. There is no mixing of air flows. There is only transfer of energy between them!

It is very efficient regarding energy consumption, allows to save up to 90% costs for heating or cooling, provides clear and fresh air inside 24/7, removes all potentially hazardous substances (dust, spores, toxic vapors etc.), helps to keep insects outside, improves comfort of life inside as there is no necessity to open windows (lower noise, less dust, no drafts).

Our approach allows to reduce heating/cooling costs below 20 kWh/m2 per year. Complete solution includes heat recovery ventilation, air-condition with inverter technology, additional electric heating in specific rooms and  proper insulation of the roof and walls. In such case  heating/cooling costs for 150 m2 house should not extend 450 EUR per year.

Air distribution system is based on flexible PE air vents with antimicrobial properties. Specifically designed components like distribution boxes, diffuser boxes with high quality diffusers provide quiet air flow and prompt exchange of the air inside the building. All parts of the system are hidden and do not prevent normal using of the premises.

Indoor air pollution can be as dangerous, or more, than outdoor air pollution. Indoor air is often more contaminated to begin with, and most people spend over 90 percent of their time indoors. Airtight modern buildings need to be properly ventilated to prevent or reduce the buildup of indoor air pollution

Ventillation is necessary to provide proper air quality inside any premises. Airflow cannot be to small  as concentration of CO2 will be to high and will cause discomfort to people inside. Too big airflow may cause very dry air inside, which also has to be avoided. Our expertise allows to design ventilation system properly for any building.
