What do you want to know?

Overview of benefits

Solar pump assembly for fitting directly to the SEM-2 solar cylinder

Rigid PUR foam or polyester fleece thermal insulation is designed to reduce heat losses during operation

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 support heat transfer and domestic hot water generation within the cylinder system

Side flange for additional internal indirect coils and maintenance

Connection for an electric booster heater

Diameter and height dimensions are designed to support temperature stratification within the cylinder

5 year statutory warranty on the floor standing cylinder

2 years on electrical and moving parts
