Overview of benefits
SEW-1W for additional integration of solar collectors
Smooth tube heat exchanger designed for DHW heating and heat transfer within the storage system.
Rigid PUR foam thermal insulation below the outer jacket is designed to reduce heat losses during operation
The interior of the cylinder is protected against corrosion by a special enamel coating and sacrificial magnesium anode
Inspection and cleaning apertures support maintenance access
