Heat Recovery Facts
Pre-heated, Filtered, Fresh air. Balanced Ventilation is key. Fresh air becomes a concern now that we tighten up our homes with insulation – sealing up all air leaks also prevents outside air from entering the building.
Heat recovery ventilation can remedy unhealthy situations
Stagnant indoor air can quickly be contaminated with pollutants like dust, mould, pollen, radon and even carbon monoxide. Heat recovery ventilation can remedy this potentially unhealthy situation, which for instance helps sufferers from asthma – but it also lowers your utility bills.
Benefits of heat recovery ventilation:
Relief of allergy problems
Controlled inlet of heated fresh air
Exhaust air evacuation
No draft sensation – “no holes in the walls”
Supports primary heating of building
Heat Recovery Venitlation Systems
Nilan VP 18 is an active heat recovery ventilation unit with heat technology for use in buildings of up to 230 sq. metres.
The VP18 produces hot water and heats the fresh air entering the house.
The heat energy in the exhaust air leaving the house is recovered by means of an air-to-water heat pump.

Demand Control Ventilation
Controlling humidity is a determining factor for a healthy building and for healthy occupants.
Small quantities of vapour are enough to cause a direct and indirect effect on the occupants health and on the building. A relative moisture ranging between 40 and 60 % is essential to the correct functioning of the respiratory system, then too much moisture turns out to be harmful for the building and occupants. In liquid or vapour form, water appears as the first cause of problems in the building sector.

Ventilate Right
This is the concept that directs the design of the Aereco products. So the "passive" components of the ventilation system are controlled and activated in various ways, according to the needs in each room and each occupation. According to the nature of pollutants and needs, the airflow can be adapted to the relative humidity, manually activated, activated by the presence or by the movement detection.

The humidity sensitive technology is applied to the air inlet and to the air extract units located in the rooms where humidity reveals the indoor pollution level. The cross sectional area of the ventilation units is controlled according to the humidity in the room. In order to keep it at an optimum level working all the year long, the sensor automatically takes into account the external temperature.

Positive Ventilation - How it Works
Condensation dampness is still a troublesome recurring problem in homes. If you can cure condensation dampness and mould growth, the rewards are enormous by improving the health of the occupants and achieving reduced maintenance costs.
The loft mounted unit is a sophisticated whole home ventilation and condensation control unit for homes with a loft space.
The unit gently ventilates the home from a central position on the landing in a house or central hallway to transform a stagnant, stale atmosphere into a fresh, healthy, condensation free environment.
