5.1.4. Laying plan
As an example for one heat pump TERRA SW 8
Complete HGL with 4 pipe circuits, distributor con-
nection in the cellar
-
In the pipe junction area, insulate the pipe to a
length of 2 m.
-
Insulate the brine supply line with cold-resistant ma-
terial; zinc-plated pipes are not permitted for use.
-
Minimum distance of the lines of 1m to water and
run-off lines, and to masonry.
-
Masonry openings must be insulated and water-
tight.
-
Insert a warning strip approx. 0.5 m above the pipes.
-
Create a laying plan and take photos.
-
The distributor connection can also be made in a
shaft outdoors.
5.2. Brine depth sensor
5.2.1.
Popis
With this system, earth probes are used for the heat
extraction in the earth area, which consist of plastic
pipes with a special plastic head.This evaporator sys-
tem requires the minimum ground surface area from
the earth evaporators. The hole diameter is 125 mm,
the drilling depth and sensor length depends on the
heat pump size. The brine medium circulates in these
plastic pipes. The heat exchange between the brine
medium and refrigerant takes place in the evaporator
set (stainless steel plate heat exchanger).
The following is required for the brine circuit con-
nection: Brass distributor with shut-off valves, safety
valve, pressure gauge, expansion vessel. Thermom-
eter and brine circulating pump are already integrated
The flexible connection hoses supplied should be
installed to avoid sound transmission. The connection
lines between the distributor and the heat pump need
to be created by the customer; zinc-plated pipes must
not be used!

5.2.2. Scope of deliver y
- Earth sensors made from plastic pipes, size de-
pends on heat pump size
- Connection set in the heat pump integrated
- Distributor, depending on order
