100% GEOTHERMAL HEAT
USER MANUAL
1. Safety
In order to ensure trouble-free operation of the Lämpöässä geothermal
heating system and achieve the best efficiency, the system must be
transported and installed in accordance with the manufacturer’s instruc
-
tions. After performance of installation works, the installation checklist
must be reviewed in order to minimise the risk of potential errors. The
manufacturer shall not accept any responsibility for equipment defects or
related expenses caused through installation faults.
The pipe and electrical installations for the Lämpöässä geothermal heat
-
ing systems can only be installed by qualified persons. If problems
should occur during installation, we recommend that you contact your
dealer or consult with Lämpöässä maintenance specialists by phone.
If the fault symbol is displayed on the touch screen, a system
malfunction has occurred. Press this button to display infor
-
mation on the cause of the malfunction.

2. Geothermal heating system operation
A geothermal (or ground source) heat pump can extract geothermal heat
from soil, water bodies or a bore hole. For an overview of the heat pump
and its operating environment, see the picture below. Of the total thermal
energy required for heating, Lämpöässä collects more than 75% from
natural sources. For thermal energy collection, approx. 25% of electrical
energy is required for running the various sys
-
tem components.
The geothermal heating system consists of heat
collection piping, water/ethanol (ethyl alcohol)
mixture circulating within the piping, and a
ground source heat pump unit. The ground
source heat pump unit comprises an integrated
hot water storage tank, compressor, heat
exchangers, and closed refrigerant circuit, i.e.,
compressor unit. The heat collection fluid in the
ground circuit, the refrigerant and the water in
the heating network never mix at any stage of
the process. Heat is transferred between fluids
using plate heat exchangers.
