  • Solar pump assembly for fitting directly to the SEM-2 solar cylinder
  • High grade rigid PUR foam or polyester fleece thermal insulation below the foil jacket of the cylinder for low heat losses
  • The interior of the cylinder and the internal indirect coils are protected against corrosion by a two-layer enamel coating and sacrificial magnesium anode
  • Large internal indirect coil surface areas ensure a short heat-up time and a high continuous DHW output
  • Side flange for additional internal indirect coils and maintenance
  • Connection for an electric booster heater
  • Optimised diameter/height ratio for good temperature stratification
  • 5 year statutory warranty on the floorstanding DHW cylinder
  • 2 years on electrical and moving parts
