Worcester Greenskies 300L Twin Coil Unvented Indirect Solar Cylinder

The Worcester Greenskies cylinder is a Stainless Steel Unvented Twin Coil Storage

vessel specifically designed to be installed in conjunction with the Worcester Greenskies

solar package. Should installation with an alternative solar package be considered please

seek guidance to ensure compatibility prior to commencing installation.

The Greenskies cylinder is not compatible in an installation utilising two individual boilers.

The Greenskies solar cylinder is made from Duplex Stainless Steel for excellent corrosion

resistance. Greenskies cylinders have a strong rust-proofed steel case and are well

insulated with environmentally friendly foam. It is available in a range of 4 sizes from

180 – 300 litres.

The Greenskies cylinder is supplied complete with all the necessary safety and control

devices needed to connect to the cold water mains. All are pre-adjusted. High quality

controls have been selected to combine high flowrate performance with minimum pressure

drop to make Greenskies cylinders perform well in most areas.

Greenskies cylinders are WRAS approved to show compliance with Building Regulations
