1 - Description
Regulus LYRA Thermal Stores are intended for accumulation and subsequent distribution of thermal energy from
solid-fuel
fi
red boilers, heat pumps, solar collectors, electric boilers etc. The Thermal Store shall be always connected
to a sealed heating circuit. The tank comes with complete accessories for connection to heating circuits, solar system
and hot water.
The accessories supplied represent a complete solution for connecting a heating system, connecting cold water inlet
for DHW heating and subsequent DHW output. In the recirculation variant this also enables connection of a circulation
pipe. The hot water circulation pump is already integrated in a fresh water station. Heat sources shall be connected to
the free inlets at the tank rear, following the diagrams included in this Manual (Chapter 5.5). When more heat sources
are combined, some intelligent controller should be used to control the heat sources and sinks, incl. the Thermal Store
charging and discharging, for example Regulus IR12 Intelligent Controller.
1.1 - Models
There are 4 models of Regulus LYRA:
- for one heating circuit, no hot water recirculation (code 12231),
- for one heating circuit, with hot water recirculation (code 12229),
- for two heating circuits, no hot water recirculation (code 12230),
- for two heating circuits, with hot water recirculation (code 12228).
1.2 - Tank protection
The inner surface has no
fi
nish, no anticorrosion protection, the outer surface is lacquered in gray.
1.3 - Thermal insulation
Thermal insulation is included in the scope of delivery. The insulation consists of 3 layers; the
fi
rst layer is made of
soft insulation tightly
fi
tting to the tank. The second, main insulation layer, features a coef
fi
cient of thermal conductivity
l=0,032 W/m.K. The third layer is represented by a tough, glossy, washable surface. The total insulation thickness is
100 mm.
1.4 - Packaging
Tanks are delivered standing, each screwed to its pallet, packed in bubble wrap. Included in the package are all com-
ponents to be
fi
tted on the tank. Insulation is in a separate package.
2 - General Information
This Owners Manual is an integral and important part of the product and must be handed over to the User. Read care-
fully 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 quali
fi
ed person according to
valid rules and Manufacturer‘s Instructions.
This appliance is designed to accumulate heating water and distribute it subsequently. It shall be connected to a heat-
ing system and heat sources. It is intended also for DHW heating, but exclusively through the enclosed fresh water
station with a plate heat exchanger.
Using the accumulation tank for other purposes than above described (e.g. as a domestic hot water tank) is
forbidden and the manufacturer 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 fitted with the
enclosed safety valve shall never exceed 110 kW.
