1 - Description
VEGA 390 Thermal Store is intended for accumulation and subsequent distribution of heating wa-
ter thermal energy. It is
fi
tted with a stainless steel immersed DHW heat exchanger, a
fl
ange in the
lower section permitting installation of a solar heat exchanger, enabling to install electric heating
rods and to connect other heat sources (a heat pump or gas boiler). The Thermal Store shall be
always connected to a sealed heating circuit.
In order to reach proper working of the tank, it is necessary to design optimum hydraulics of the
whole system, i.e. position of circulation pumps for sources and heating circuits, valves, non-return
valves etc. When more heat sources shall be combined, it is recommended to use an intelligent
controller, e.g. Regulus IR12, for both the source and load sides of a heating circuit, i.e. also for
charging and discharging the Thermal Store.
1.1 - Models
VEGA 390 with stainless steel DHW heat exchanger.
1.2 - Tank protection
The Thermal Store comes with no inner surface
fi
nish, its outside painted in grey. Its DHW heat
exchanger is made of stainless steel.
1.3 - Thermal insulation
Thermal insulation is included in the supply. It consists of 3 layers: the
fi
rst one is soft insulation
fi
tting tightly on the tank; the second, main layer, features thermal conductivity l=0.032 W/m.K; the
third layer is a hard, glossy washable surface. The total insulation thickness is 100 mm.
1.4 - Connection points
1 top sleeve with G 1/2“ F thread
7 side sleeves with G 1/2“ F thread
2 side sleeves with G 6/4“ thread
6 side sleeves with G 1“ thread
2 G 1” sleves - stainless-steel heating coil inlet and outlet
1.5 - Packaging
Tanks are delivered standing, each screwed to its pallet, packed in bubble wrap.
Included in the package are all components to be
fi
tted on the tank. Insulation is packaged sepa-
rately.
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 con-
cerning safety, installation, operation and maintenance. Keep this Manual for later reference.
This appliance is designed to accumulate heating water and distribute it subsequently. It shall be
connected to a heating system and heat sources. This appliance is also suitable for instantaneous
water heating.
Using the Thermal Store for other purposes than above described is forbidden and the manufac-
turer accepts no responsibility for damage caused by improper or wrong use.
The output of heat sources not equipped with their own safety valve and connected to the tank
fi
tted with the enclosed safety valve shall never exceed 110 kW.
