1 Description
Regulus LYRA Thermal Stores are intended for accumulation and subsequent distribution
of thermal energy from solid-fuel fired 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. 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 3 models of Regulus LYRA 1000 DVS:
- for 1 heating circuit, no DHW recirculation, no pool
- for 2 heating circuits, with DHW recirculation, with pool
- for 2 heating circuits, with DHW recirculation, no pool
1.2 Tank protection
The Thermal Store comes with no inner surface finish/anticorrosion protection, its outside
is painted in grey.
1.3 Thermal insulation
Thermal insulation is included in the supply. It consists of 3 layers: the first one is soft
insulation fitting tightly on the tank; the second, main layer, features thermal conductivity
λ=0.032 W/m.K; the third layer is a hard, 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 components to be fitted on the tank. Insulation is packaged separately.
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. Installation shall be done by qualified staff only, in compliance with
valid rules, standards and manufacturer’s instructions.
This appliance is designed to accumulate heating water and distribute it subsequently.
It shall be connected to a heating system and heat sources.
Using the Thermal Store for other purposes than above described (e.g. as a
drinking 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.
