Screed heating
Heat pump heating systems partially have a basically other behaviour them conventional incinerators since they are
pretty well designed for the nominal heat requirement and dispose of a minimum surplus power in order to help you
save money. Our experiences have shown that exactly for this reason some building owners have doubts about the
performance of the heat pump in their new detached house when moving in. When moving in a new massive built
home in the cold season it often reveals that the heat pump heating cannot perform both requirements: drying out a
solid construction and covering the transmission and ventilation heat requirement.
In a solid built house there are huge quantities of water (walls, plaster, screed, etc.). In former times at least one year
past from the start of construction until moving in the house naturally dried out in winter. Nowadays everything must
happen within only a few weeks – but not only with the help of the heat pump.
Please note:
In order to evaporate 1000 l of water at a temperature of 20 °C about 680 kWh energy are required!
When using a gas heater for instance a 17-20 kW device is used for a nominal heat requirement of 10 kW in order to
guarantee the required hot water preparation. Of course there are sufficient reserves for the dry heating phase. Expect
to spend more money in electricity costs during the first heating period due to the dry heating phase. In pre-fabricated
houses where there are no solid walls the dry heating phase is limited to the floor screed and therefore this period is
considerably shorter.

Decommissioning
Provisional decommissioning:
By actuating the power switch and turning it to the position "OFF“ the system is
decommissioned. Due to the risk of freezing it is only allowed to decommission
the system without emptying the heating circuit at temperatures of more than
0°C.
Final decommissioning / disposal:
Before removing the heat pump, disconnect the machine from the power supply
and shift it off.
A final decommissioning / disposal is only allowed if it is performed by an expert
company.
The heat pump contains electrical and electronic components. In case of improper
disposal they might have adverse effects on the environment. Herewith the manu-
facturer specially points out that the device must not be disposed of as domestic
waste but it is necessary to dispose of it as hazardous waste.
Environmentally relevant requirements with regard to recycling, reuse and dispos-
al of fuels and components according to the common standards must be complied
with. At this it is particularly important to ensure a professional disposal of the
coolant and refrigeration oil.
