1 - Description
HSK PV Thermal Stores are intended for storing and subsequent distribution of thermal energy of heating water. They
are fitted with a stainless-steel tube DHW heat exchanger, permitting installation of electric heating elements and
connection of other heat sources. For a better thermal layering, the tank volume is separated by a baffle.
For proper operation of a tank, it is necessary to have an optimum hydraulic design of the entire heating system, i.e.
position of circulation pumps for both heat sources and heating circuits, valves, check valves etc. When more heat
sources shall be combined, it is recommended to use a smart controller for both the heat source and heat sink sides
of a heating circuit, i.e. also for charging and discharging a thermal store.
1.1 - Models
Four models of 557, 757, 922 and 1684 l total volume, with stainless-steel tube DHW heat exchanger.
1.2 - Tank protection
The thermal store has no inner surface nish, the outer surface is painted in gray. The DHW heat exchanger is
made of stainless steel.
1.3 - Thermal insulation
Thermal insulation is available as a separate item. For easier handling, the insulation shall not be fitted on the tank
until it reaches its definite place of installation. This is a fleece insulation, 100 mm thick, with a hard polystyrene surfa-
ce. It is closed by quick locks.
1.4 - Packaging
Thermal stores are delivered standing, each screwed to its pallet, packed in bubble wrap.
It is forbidden to transport and/or store the thermal stores in a horizontal position.
2 - General Information
This Owners Manual is an integral and important part of the product and must be handed over to the User. Read
carefully the instructions in this Manual as they contain important information concerning safety, installation, operation
and maintenance. Keep this Manual for later reference. The appliance shall be installed by a qualified person
according to valid rules and Manufacturer‘s Instructions.
This appliance is designed to accumulate thermal energy and distribute it subsequently. It must be connected to a
heating system and heat sources. This appliance is suitable for continuous heating of domestic hot water.
Using the thermal store for other purposes than above described is forbidden and the manufacturer accepts no
responsibility for damage caused by improper or wrong use or filling procedure.
The appliance shall be installed by a qualified person according to valid rules, otherwise the warranty becomes null
and void.

HSK 600 PV Combination Thermal Store
Main features
Application accumulation of thermal energy for space and DHW heating
Description
this combination Thermal Store utilizes a heat pump with
PV panels as a heat source for both space and DHW heating;
DHW is being prepared in 2 integrated stainless-steel heat
exchangers; a tightly tting separating metal plate increases
the heat pump’s seasonal coe󰀩cient of performance,
a dedicated PV heating element is placed in the lower
tank section; more electric heating elements can be
installed if needed
