Living comfort and energy savings
Living comfort and energy savings are becoming
increasingly important in housing construction.
Nowadays, homes are increasingly insulated, but
unfortunately good insulation often comes at the
expense of the indoor climate.
Without good ventilation, moisture, moulds and dust
mites can escape, and the air in the house can quickly
feel 'stuffy' due to an increasing concentration of CO2
(carbon dioxide). Itho Daalderop installs equipment that
regulates the indoor climate and takes into account the
requirements for comfort and energy consumption in
homes.
One of these advanced devices is the Itho
Daalderop ventilation system HRU ECO 350.
The HRU ECO 350 is a balanced ventilation system
with heat recovery. The ventilation unit is equipped with
two fans; one for the return air and one for the supply
air.
The ventilation unit ventilates several rooms in the
house. By means of ducts, the kitchen, the bathroom, the
toilet and possibly the indoor storage/laundry room (the
'wet rooms') are connected to the ventilation unit for the
removal of polluted/humid air.
The living room, the bedrooms and possibly the
corridor/hallway are also connected to the ventilation unit
by means of ducts, but fresh air is brought in here.
To ensure good air distribution, the supply and return
points in the rooms to be ventilated are fitted with
extraction valves and supply grilles respectively.
In this way, the HRU ECO 350 helps to reduce the
humidity in your bathroom, refresh the toilet and drive
cooking odours out of the kitchen.

Heat recovery
Before the polluted air is removed to the outside, it is
filtered and passed through the heat exchanger. The
fresh outside air is also filtered and passed through the
heat exchanger before it is brought into the house. In the
heat exchanger, the two air flows are routed past each
other (i.e. they are not mixed with each other). As a
result, the heat
of the exhaust air transferred to the fresh supply air, so
that this energy is not lost.
Heat recovery takes place with a very high efficiency.
On average, about 90% of the heat removed is
returned to the home. So there is only about 10% heat
loss.
