What is the difference between secondary air and
recirculating air?
Recirculating air is extract air which is treated and then
fed back as a component of the supply air to at least
one room from which it was not originally taken. This
means it is possible for odours and substances to be
transmitted. In contrast, secondary air is removed from a
supply air zone, fed through a separate duct system and,
after treatment, is fed back into the same room.
Mixing with the extract air is therefore excluded. This
also applies to the Genius system. The only difference is
that the secondary air is fed back into the entire supply
system after treatment, not to one room.
For what buildings is Genius appropriate?
The application limits are:
Passiv house/KfW 40: max. 230 m2 living area
KfW 55: max. 190 m2 living area
Heating load calculation necessary.
What other basic requirements must be met?
The supply air duct system must be designed for the
higher ow rates and must be insulated
A separate duct system is required for the secondary air.
Additional electric convectors or underoor heating is
recommended in bathrooms
Is the Domestic Hot water tank sufcient to supply a
one-family household without additional electrical
energy?
With Genius, the hot water is produced on demand and
is possible during all operating states, i.e. also during
heating and cooling. The domestic hot water tank
holds 150 litres. Thanks to the parallel operation and
the performance of the heat pump, this is sufcient
for a one-family household, even with a high level
of consumption. The additional electrical heating
element only has the following functions: Legionella
control program, fast charge, emergency operation and
assistance when the outside temperatures are extremely
low.
Can Genius be operated in combination with a
replace?
Yes, as long as the replace is installed independently
of the ambient air. This is because if an ambient
air-dependent replace is operated in parallel to a
ventilation system, the possibility must be ruled out
that, if an underpressure forms, exhaust gases from
the replace enter the room. Here, safety measures are
required which could result in the system being switched
off. Since Genius also provides the entire heating
function, any shutdown must be prevented.
The heat from an ambient air-independent stove
operated in parallel can be simply and evenly distributed
throughout the whole house via the Genius secondary air
duct system.
How can the temperature be regulated in individual
rooms?
With an air heating system, you can control the
temperature of a single room using the PTC reheating
elements. Here the heat pump only supplies the
temperature which is demanded by the room controller
which is congurated as reference room (this is generally
in the bedroom). The temperature increase in the other
rooms is provided individually by the electrical reheating
elements
