Short description

Hygienic stratification storage tank
HSK-ÖKO 700 PLUS, the versatile heating
centre with integrated corrugated
stainless steel pipe for legionella-safe
hot water preparation. Two large heat
exchangers for zone loading for improved
efficiency of the solar thermal system.
Integrated stratified charging tower for
improved stratification of the heating
return for higher system efficiency.
Connections for sensors, thermometers
and an electric immersion heater for
more flexibility. Double fire protection
fleece insulation ISO-B1-PLUS with 220mm
insulation thickness made from recycled
fibres (Oeko-Tex® Standard 100) incl.
floor insulation for low heat loss.
Rugged PVC jacket with stainless steel
quick-lock system for easy installation.
In order to penetrate the second
insulation layer, we recommend the
optionally available connection piece
extensions as well as the B1-Plus
thermometer set.
