Main Features
Application
Combination thermal store with integrated stainless-steel heat
exchanger and a tight separating metal sheet is intended for
heat accumulation and DHW heating. Thanks to its modified
design and the tight separating metal sheet, just one zone
valve is sufficient for switching between heating the upper
and lower tank sections. The tank is suitable for installations
with heat pumps and RegulusBOX indoor unit. The tank
insulation is not included in supply and shall be ordered
separately, see the code below.
Working fluid
water; water/glycol mixture (max. 1:1) or water-glycerine
mixture (max. 2:1) (tank); water (heat exchanger)
