Characteristics

• Factory pre-assembled compact loading group, which ensures trouble-free and quick installation to heat storage and heat source systems
• The loading group provides a rapid rise in heat source temperature and storage loading starts automatically as soon as the operating temperature is reached, thus improving boiler efficiency and service life
• At the initial stage of loading, rapid storage tank temperature stratification makes it possible to obtain heat energy very quickly after the start of the combustion
• Automatic shut-off function closes the bypass line in the final stage of loading to ensure maximum loading the storage tank
• Return temperature is steplessly adjustable from 0 to 95 °C with a single control knob
• Ideal for use with water based fireplaces and stoves thanks to the easily adjustable return temperature, various heat sources can always be operated at optimum temperature
• The charging group is easy to maintain and all wearing parts are easily replaced without the need to drain the water system
