Overview of benefits

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 floor standing cylinder

2 years on electrical and moving parts
