Hydronic Floor Heating
You should be aware that for the first year,
heating expenses for a newly laid, heavy floor
heating system will be 20-30% higher.
This is because the energy required to evapo-
rate the water trapped in the concrete can only
be derived from the heating system.
In a 150 m
2
house with heavy floor heating,
some 1500 litres of water have to evaporate
during the first year.
Operating economy
1500 litres of water
30 tonnes of concrete
Opening windows to ventilate a room
When ventilating a room, you can use the
heat-stop button on the room sensor in that
room.
By pressing the button, all heating in the room
concerned will be stopped and the display will
turn completely blank.
Pressing the button again turns on the heat
and the current room temperature will be
shown in the display.
Please note: You can lock the heat-stop button if you are
afraid of accidentally pressing it or e.g. have
young children in the house. See the front
of this user guide:
Does the Danfoss One
®
system have a tamper-proof lock?
If you have a Danfoss Air ventilation system, it is
of course not necessary to open the windows.
