Gledhill PLUIN300B StainlessLite Plus Indirect Buffer Store 300L Vented Cylinder

The Gledhill PLUIN300B is an open-vented duplex stainless steel indirect buffer store designed specifically for use with air source or ground source heat pumps. It provides additional volume to the heating distribution system, helping to reduce short cycling of the heat source while supporting indirect connection to gas or oil boilers via a high-efficiency corrugated coil.

Manufactured to the highest standards with automated welding and post-weld treatment, this 287-litre model suits trade installers and specifiers working on renewable heating projects where potable domestic hot water storage is not required. It is the lightest cylinder in its class and carries an ErP C rating.
