Hydronic Floor Heating
Can I use temperature reduction periods when I have floor heating?
Yes, you can, as long as you keep certain things
in mind.
Heavy floor heating
We recommend one long temperature reduc-
tion period (at least 7 hours) with a slightly
lower
economy temperature
setting.
The difference between the
comfort
and
the
economy temperature
must not be more than
1-2 degrees.
Lowering the temperature too much will pre-
vent the system from reaching the low tempe-
rature and no energy saving will be achieved.
Please note: You should be particularly aware of this if
your heat source is a heat pump.
If you attempt to achieve too great a reduction
in temperature you risk the heat pump having
to activate its supplementary heat source (elec-
tric heating element) when reheating begins.
This will have a negative impact on your energy
consumption.
Light floor heating
We recommend setting a lower
economy tem-
perature
for one or two extended periods.
The difference between the
comfort
and
the
economy temperature
must not be more than
3-4 degrees, as otherwise the system will not
be able to keep up.
Please note: You should be particularly aware of this if
your heat source is a heat pump.
If you attempt to achieve too great a reduction
in temperature you risk the heat pump hav-
ing to activate its supplementary heat source
(electric heating element) when reheating be-
gins. This will have a negative impact on your
energy consumption.
