2.1. A comfortable living environment
and energy conservation
A comfortable living environment and energy
conservation are becoming increasingly important in
housing construction. The insulation of modern dwellings
is getting better all the time, but unfortunately good
insulation often comes at the expense of the indoor
climate. Without good ventilation, there is nothing to
stop damp, mould and dust mites, and the air in the
dwelling can quickly start to feel stale due to the
increasing CO
2
concentration (carbon dioxide). Heatrae
Sadia installs appliances which manage the indoor
climate and take account of requirements for comfort and
energy consumption in dwellings.
The HRU ECO 4 ventilation system from Heatrae Sadia is
an example of these advanced appliances.
The HRU ECO 4 is a balanced ventilation system with
heat recovery. The ventilation unit is equipped with two
fans: one for air exhaust and one for air supply.
The unit ventilates several rooms in the dwelling. Stale or
humid air is extracted from the kitchen, bathroom, toilet,
and any indoor storage spaces or washrooms ("wet
rooms") through ducts connected to the ventilation unit.
The living room, bedrooms and hallway are also
connected to the ventilation unit by ductwork, but in
these rooms there is no air extraction, just fresh air
supply.
To ensure good air distribution, the extraction and supply
points in the ventilated rooms are fitted with extractor
valves and supply grilles.
The HRU ECO 4 helps to reduce humidity in your
bathroom, keep the toilet smelling fresh and remove
cooking odours from the kitchen.
