Torrent ECO HP-Solar Models
The heat pump and space heating system
configurations and operation with the Torrent
ECO HP-solar models is the same as for standard
models. The solar thermal system operates
independent of the heat pump system. A
typical generic solar system configuration is
shown for guidance only. The solar system and
the associated controls should be planned and
installed following manufacturers instructions.
All components in the solar primary system
must be marked or identifiable in such a way
that their design pressure and temperature can
be readily determined.
A safety device i.e. pressure relief valve to control
the risk of over-pressure in the system components
should be fitted as per solar system manufacturers
instructions. A termination from the pressure
relief valve should minimise the risk of damage
to persons or materials. Suitable locations are a
high temperature receptacle, internal gully or else
externally at ground level. High level termination
from a wall or on a roof could cause injury to
people or animals below if the valve were to release
scalding water and steam.
The pipe leading to from the safety device to the
collector should be rigid and non-deformable
construction, without any possibility of
restriction, distortion or closure by any other
fitted component.
A typical wiring diagram for the solar thermal
system for the Torrent ECO HP-solar is shown
on page 35.
The control packages supplied with the heat
pump can not only control the heat pump but
any backup devices as well, for example, solar
thermal, gas boiler and immersion heater flow
boilers.
