5.6 Connection of External Heating Source (alternative / additional source)
Sanitary water in the water storage tank may be heated with the device generator - heat
pump (primary source) and / or additional heat sources (serially equipped electric heater or
various external sources).
The external source is that which produces heat separately from the device and is
connected to the device through a pipe heat exchanger inside the DHW tank. External heat
sources are considered those which are available at all times (additional external electric
heater, fuel oil/gas/pellet/biomass boiler) or those which are at disposal only occasionally
(solar panels, wood-fired furnace, fireplace, etc.).
If a temperature sensor is installed into the external source the regulation checks the
temperature of the external source and adjusts the activation of the external source
circulation pump according to the need for domestic hot water and according to the
temperature of the external source. For proper functioning you must connect the circulation
pump and the temperature sensor correctly and set the parameters in the device controller.
For a proper electrical connection of the attachments follow the instructions in the chapter
about the electrical connection, and for the setting of the controller, the chapter on operation.
WARNING
Due to use of different materials on the pipe installation, all connections (cold water,
hot water, circulation, heat exchanger) on the device must obligatorily be
galvanically isolated, or the corrosion of connections within the heat storage may
occur. We recommend galvanic separators from red alloy for each attachment, at
least 2x pipe diameter in length.
WARNING
Water used for sanitary water heating through the installed heat exchanger in the
hot sanitary water tank must comply with requirements of standard VDI 2035. The
heating system must be filled with soft water, which contains anti-corrosive and
anti-bacterial substances for prevention of corrosion. Before filling, the heating
system must be cleaned of all impurities.
The heating system must be thoroughly drained of all air. Prevent the intrusion of
air into the system, including diffusion air.
