REGULUS - DUO N P Thermal Stores - www.regulus.eu
1 - Description
DUO N P Thermal Stores are intended for storing and subsequent distribution of thermal energy from various
heat sources like solid-fuel boilers, heat pumps, electric boilers etc. A DHW tank is integrated inside the thermal
store. For a better thermal layering, the tank volume is separated by a metal plate. The thermal store shall to be
connected to a closed heating system with forced circulation.
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 consumer sections of a heating circuit, i.e. also for charging and discharging a thermal store.
1.1 - Models
Models DUO 390/130 N P, DUO 600/200 N P, DUO 750/200 N P, DUO 1000/200 N P, DUO 1700/200 N P
permitting installation of electric heating elements and other external heat sources.
1.2 - Tank protection
The inner DHW tank is made of stainless steel. A chain-type magnesium anode is installed in it for an increased
level of protection. The thermal store has no inner surface finish, the outer surface is lacquered.
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. The insulation is made of fleece, 100 mm thick, with a hard
polystyrene surface. It is closed by quick locks.
1.4 - Packaging
Thermal stores are delivered standing, each screwed to its pallet, packed in bubble wrap. The tank is then
shrink-wrapped together with its pallet.
It is forbidden to transport and/or store the thermal stores in a horizontal position.
